Observe: Hold your cursor over one of the insects. The two rod-like structures under Genotype on the right side of the Gizmo represent chromosomes. The three letters next to each chromosome represent alleles. Which alleles does the insect have
Complete question:
Question: Where does variation in a population come from?
1. Observe: Hold your cursor over one of the insects. The two rod-like structures under the Genotype on the right side of the Gizmo represents chromosomes. The three letters next to each chromosome represent alleles.
Which alleles does the insect have? ____________________________________________
The alleles carried on an organism’s chromosomes make up the organism’s genotype
Answer:
Allele = WGenotype = WWW WWWExplanation:
First, you need to set red = 100, gree = 255, and blue = 50.You will see that the average fitness of individuals changed to 53%. Natural selection should be selected. Now, you need to click on any of the insects, and it will appear the chromosome on the right. You will see the word Genotype, and under it, you will see the chromatids.You will see that each chromatid has three alleles. Next to each allele, you will see which version of the gene is (W). In this particular example, all the alleles are the same, so all of them express white. Both chromatids carry only W alleles.
Think about alleles as an alternative form of the gene. So on this chromosome, we have only three genes but eight possible alternatives, which will be coding for white, red, blue, green, cyan, magenta, yellow, or black. The color expression will depend on the individual´s genotype.
In this case, the selected insect carries only the W allele, and its phenotype is white. The genotype of this insect is WWW WWW.
Note: If you click on any other insect, you will find the same genotype for all of them.
However, consider that depending on the environmental conditions and the selective pressures, these alleles might change. Individuals might carry other alleles that code for another color instead of having only W alleles.

One way to think about the importance of biodiversity is simply to think in terms of natural capital: the roles that genes, species, ecosystems, and ecological processes play in supporting human society and a healthy biosphere. What are benefits provided by biodiversity?
Answer and Explanation:
Biodiversity composes of different species living in a certain restricted area. It is the variability of living beings in a natural environment, involving all the species on the planet and their genetic material. This variety includes all plants, animals, fungus, and microorganisms living in a certain place, their genetic variability, and the ecosystems these species form.
Ecosystems include all the biotic, physical, and chemical components of nature, continuously interacting and depending on each other. The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.
Biodiversity, in equilibrium with abiotic factors, provides ecosystem services, which are important for the maintenance of all forms of life, including human beings.
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems provide a recreational place or area to spend time and learn. They provide a spiritual/religious space, are a source of inspiration. Ecosystems are cultural patrimony and the source of scientific knowledge.

In the lab, you isolate a mutant strain of bacteria in which the phosphatase that would normally dephosphorylate NtrC-P is defective. Assuming the levels of NtrB and NtrC protein remain normal (same as wild type), what is the expected phenotype of this mutant
Answer:
GlnA will be overexpressed and the cells will have more glutamine than glutamate
Explanation:
Glutamine synthetase (glnA) is an enzyme involved in nitrogen metabolism that catalyzes the amidation of glutamate to glutamine. Moreover, the phosphorylated form of the NtrC response regulator protein (NtrC~P) acts as a transcriptional activator of genes associated with nitrogen metabolism, including glnA. NtrC~P exhibits 1-an enhanced DNA binding activity (increased oligomerization on the target DNA template) and 2-ATPase activity (oligomerization of the NtrC phosphoprotein), which are fundamental features for transcriptional activation. In consequence, it is expected that a higher level of NtrC~P (due to a defective form of the phosphatase that dephosphorylates NtrC~P) leads to the overexpression of glnA, thereby increasing glutamine levels and simultaneously decreasing glutamate concentration.

Explanation:
In a college biology experiment, 50 mg of methane and 60 mg of sulfate are mixed in a closed container. What is the limiting reagent, and how much excess reagent remains when that species has been exhausted
Answer:
CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.
0.040 g
Explanation:
Step 1: Write the balanced reaction for the methane anaerobic oxidation
CH₄ + SO₄²⁻ ⇒ S²⁻ + CO₂ + 2 H₂O
Step 2: Establish the theoretical mass ratio between the reactants
According to the balanced equation, the theoretical mass ratio of CH₄ to SO₄²⁻ is 16.04:96.06 = 0.1670:1
Step 3: Establish the experimental mass ratio between the reactants
50 mg (0.050 g) of CH₄ react with 60 mg (0.060 g) of SO₄²⁻. The experimental mass ratio of CH₄ to SO₄²⁻ is 0.050:0.060 = 0.83:1
Comparing both mass ratios, we can deduce that CH₄ is the excess reagent and SO₄²⁻ is the limiting reagent.
Step 4: Calculate the mass excess of CH₄
The mass of CH₄ that reacts with 0.060 g of SO₄²⁻ is:
0.060 g SO₄²⁻ 16.04 g CH₄/96.06 g SO₄²⁻ = 0.010 g CH₄
The mass excess of CH₄ is:
0.050 g - 0.010 g = 0.040 g
Which statement is true of human cultures? O A. All human societies share the same cultural traits and practices. O B. Every human has a unique set of cultural traits and practices. O C. Culture includes a society's knowledge, customs, and achievements. O D. Cultures are groups of people united by blood relationships. SUBMIT
Answer:
B. Every human has a unique set of cultural traits and practices.
Explanation:
Culture can be defined as the general way of life of a group of people living together in a particular location or society.
Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
This ultimately implies that, culture are acquired and passed from one generation to another.
A cultural trait can be defined as the smallest characteristics of human activity (actions) that is mainly acquired socially and transmitted from one generation to another through various modes of communication.
This ultimately implies that, these unique behavioral informations or characteristics and beliefs acquired by people socially are transmitted from one individual or group of people to another.
Hence, the statement which is true of human cultures is that every human (race) has a unique set of cultural traits and practices that were acquired from the environment and society.

Peppered Moths
Before the Industrial Revolution there were more sightings of light-colored moths and
fewer sightings of dark-colored moths. As factories were built during the Industrial
Revolution, pollution increased. At this time, scientists observed that the number of
light-colored moths decreased, while the number of dark-colore moths increased and
became more abundant in the population than the light-colored variety.
Which graph represents how natural selection acted on moth coloration during
the Industrial Revolution? The dotted line represents the original population and the
solid line represents the population after selection.
Answer:
The correct answer is - Option B.
Explanation:
Before the Industrial Revolution, the light color moths were predominant so that they can blend in with the light-colored trees and lichens in their environment. After releasing coal smoke from factories, the trees became darkened, and the light-colored moths become an easy target for predator birds to spot.
Over time, the frequency of the dark moth increased due to they had a higher survival rate in habitats affected by the air pollution and it blends with darker coloration blended with the sooty trees. This is a shift in the population’s genetic variance toward the new, phenotype.
In graph B, light color moth frequency decreases, and after natural selection increases over time and after a decrease in evolution the dark color again decreases.

¿De qué manera pueden complementarse la
teoría Sintética y la teoría de los Equilibrios
Puntuados?
La teoría sintética
El redescubrimiento en 1900 de la teoría de la herencia de Mendel por el botánico y genetista holandés Hugo de Vries y otros llevó a un énfasis en el papel de la herencia en la evolución. De Vries propuso una nueva teoría de la evolución conocida como mutacionismo, que esencialmente eliminó la selección natural como un proceso evolutivo importante. Según de Vries (a quien se unieron otros genetistas como William Bateson en Inglaterra), en los organismos tienen lugar dos tipos de variación. Una es la variabilidad "ordinaria" observada entre los individuos de una especie, que no tiene consecuencias duraderas en la evolución porque, según de Vries, no podría "conducir a una transgresión de la frontera de la especie [es decir, al establecimiento de nuevas especies] incluso en las condiciones de la selección más rigurosa y continua ". El otro consiste en los cambios provocados por mutaciones, alteraciones espontáneas de genes que dan lugar a grandes modificaciones del organismo y dan lugar a nuevas especies: “La nueva especie se origina así de repente; es producido por el existente sin ninguna preparación visible y sin transición ”.
Muchos naturalistas se opusieron al mutacionismo y, en particular, los llamados biometristas, liderados por el estadístico inglés Karl Pearson, quien defendió la selección natural darwiniana como la principal causa de la evolución a través de los efectos acumulativos de variaciones individuales pequeñas y continuas (que los biometristas se supone que pasa de una generación a la siguiente sin estar limitado por las leyes de herencia de Mendel).
The button-like structure that holds homologous chromosomes together at their middles during cell division is called the
Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.
Sickle cell disease is a recessive trait which causes a deformation in red blood cells due to a mutation in the gene that codes for hemoglobin. Consider a father and a mother BOTH with the genotype Hh, where H is the normal hemoglobin gene, and h is the gene that codes for the defective hemoglobin. What percent of their children will have the genotype hh, which means they will have the full-blown disease?
Answer: Sickle cell disease is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. Hemoglobin transports oxygen from the lungs to other parts of the body. Red blood cells with normal hemoglobin (hemoglobin-A) are smooth and round and glide through blood vessels.
Explanation:
A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 4,000 gC/m2/day; Primary consumers: 480 gC/m2/day; Secondary consumers: 72 gC/m2/day; Tertiary consumers: 24 gC/m2/day.
Does this ecosystem follow Lindeman's Law for ecological efficiency?
a. Yes, the average efficiency is 20%
b. Yes, the average efficiency is 10%
c. No, the average efficiency is 20%
d. No, the average efficiency is 10%
Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
Yes, the energy available to all trophic levels is in the average of 10% which
follows Lindeman's Law for ecological efficiency.
Lindeman's Law for ecological efficiency states that the energy transfer from
one trophic level to the other should have a 10 percent efficiency. The
trophic level starts with the primary producers having more energy and the
tertiary consumers having the least amount of energy.
The example given shows that the different trophic levels in the ecosystem
have about 10 percent efficiency during energy transfer and availability.

force is the overall force on an object after all the forces
are added together.
Answer:
The correct answer is - Net force.
Explanation:
Adding all the forces that are applied to a particular object, body, or particle is the net force. This overall force that is applied can be calculated by a vector sum of all other forces exerted on the body.
So if two forces are applied in opposite directions to one another, they combine by subtraction whereas If one force is less than the other force, the net force is in the direction of the greater force.
