What are bio-fuels considered carbon neutral?
Answer:
Science considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel, such as soybeans and palm oil trees, absorb carbon dioxide (CO2) as they grow. The absorption of CO2 by these plants offsets the CO2 that forms while making and burning biodiesel.

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?
Answer:
Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.
Explanation:
Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.
In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.
How is your body temperature held constant despite different weather temperatures
outside?
Answer:
Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.
Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

Where is most of the baryonic matter (ordinary matter) of the universe found?
A. in planets and natural satellites
B. in comets and asteroids
C. in dark matter and dark energy
D. in interstellar gases and stars
Most of the baryonic matter (ordinary matter) of the universe is interstellar gases and stars. Baryonic matter is the visible matter. Thus, the correct answer is D.
What is Baryonic matter?Visible matter is also known as the baryonic matter. It consists of baryons which are subatomic particles such as protons, neutrons and electrons.
In cosmology, baryonic dark matter is the dark matter composed of baryons. Only a small proportion of the dark matter in the universe is likely to be baryonic the rest of the matter is all dark matter. Baryonic matter only includes matter composed of baryons. It can be described as the baryons are made up of protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude other things like electrons and neutrinos.
Therefore, the correct answer is D.

What is the sediment deposited by surface water?
Answer: Delta
Explanation:
A delta is the sediment deposited by the surface water. When the river flows it carries the sediments from the bedrock and also from the surface of the top layer of the soil. These sediments are deposited on a fan like formation that is called as delta. It leads to the development of a landform. It is the most fertile landform as the sediments are rich in mineral content that promote the growth of the plants. This develops when river enters into the ocean, estuary, reservoir, lakes, and any other water body supplying the sediments on the surface.
Calculate the ratio of the size of the bacterial cell to the size of the mesophyll cell
bacterial cell is 1 micrometer
mesophyll cell is 0.05mm
Answer:20 to 1
Explanation:
]
The ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20. It means that 20 bacterial cells can fits into a mesophyll cell.
Given here,
Size of the bacterial cell = 1 micrometer
Size of the mesophyll cel= 0.05mm
Equalize the measuring unit,
1 micrometer = [tex]\bold{10^-^6 m}[/tex]
1 millimetre = [tex]\bold { 10^-^3 m}[/tex]
So the ratio will be
[tex]\bold { = \dfrac{ 1 x10^-^6 m}{0.05 x 10^-^3 m} }\\\\\bold { = \dfrac 1{20} }[/tex]
Therefore, the ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20.

10. Refer to p. 484 of your textbook. In sex-linked heredity, the characteristic gene is found on the X
(sex) chromosomes; therefore, it is inherited along with the sex of the individual. Hemophilia (X") is
the result of a recessive sex-linked allele. A carrier has one recessive allele for hemophilia; therefore,
she does not have hemophilia but can pass it on. If a normal male marries a carrier, what is the
probability that they will produce a male child who will be a hemophiliac? What is the probability
that they will produce a female child who will have the disease? What is the probability that they
will have a daughter who is a carrier?
Answer:
they have a chance of 25% of producing a male child who will be haemophiliac.
Explanation:
0% of producing a female child who will have haemophilia
25% of having a daughter who is a carrier

Explanation:
what is to be searched for is a scientific knowledge of essences in contradistinction to a scientific knowledge of facts?
Answer and Explanation:
Scientific knowledge must always be focused on the search for facts and not essences, since they are the facts that manage to expose the functioning and composition of elements that are directly or indirectly interacting with human beings.
This is due to the fact that scientific knowledge is knowledge produced through tested and proven evidence, which is able to answer a question based on evidence, that is, the nature of scientific knowledge is the exposure of facts. Thus, we can affirm that, there is no scientific knowledge established in essences, because essences are subjunctive elements, impossible to be tested and proven.
what is photosynthesis
Answer:
photosynthesis is the cycle of plants using sunlight water and carbon dioxide.
Answer:
Photosynthesis is the process in which carbon dioxide, sunlight, and water gets turned into energy (glucose) by plants, and the plant releases byproducts (oxygen) back into the air.
Explanation:
Inside the plant is a small organelle (a little body inside a cell dedicated to a certain job) called a chloroplast. When a plant is in sunlight, it gets absorbed into the chloroplast and converted into energy by the chloroplast. While the plant is absorbing sunlight, it is also taking in CO2 (Carbon Dioxide), H2O (Water) and minerals from the soil to help in the process to generate energy.

A.Meiosis and fertilization B. Mitosis and fertilization C. Mitosis and Meiosis
D. Asexual reproduction and sexual reproduction
Answer: c
Explanation:
Meiosis and fertilization, two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fish and other animals.
What is meiosis and why is it important?Meiosis occurs in chromosomes which allows the production of haploid germ cells necessary for seˣual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Fertilization restores the diploid number of chromosomes, that is 46 in human being. It provides stimulus for the ovum to complete its maturation.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.
Genotype
Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green
84%
F (dominant)
Dark green plumage
ff
White
16%
f (recessive)
White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)
Group of answer choices
The student needs the percent of the population with the Ff genotype in order to find the F frequency.
Her research advisor would first want her to find the males' mating success rate for the calculations.
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.
