Explain how an algal bloom affects the oxygen levels in a lake ecosystem.

Answers

Answer 1

Answer:

Algal bloom causes by eutrophication (when excess nutrients run into a body of water). Eutrophication provides nutrients for algal bloom. As a result, there is an increasing in algal bloom population. Increasing in algal bloom population can block the light that is needed by other organisms. This could impact these organisms survival. Furthermore, when these algae die, their body sink into the bottom of the sea, which consider as nutrients for bacteria, increasing bacteria population. This means that the respiration rate by bacteria is increasing as well. When bacteria respire, they need to absorb oxygen. Over time, these oxygen level will eventually decrease and later form a dead zone.

Scientific evidence shows that modern dogs, wolves, and foxes all have a common ancestor. Further evidence shows that dogs are more closely related to wolves than to fixes. Which of the following observations provides the BEST evidence that dogs are more closely related to wolves than to foxes? *
A. The diets of dogs and wolves are more similar that the diets of dogs and foxes.
B. The lifespans of dogs and wolves are more similar than the lifespans of dogs and foxes.
C. The genetic sequences (DNA) of dogs and wolves are more similar than the genetic sequences of dogs and foxes.
D. The body sizes of dogs and wolves are more similar than the body sizes of dogs and foxes.

Answers

The observation that provides the best evidence that dogs are more related to wolves than to foxes is the DNA sequence of dogs and wolves being more similar than that of dogs and foxes.

The DNA is a molecule that stores the genetic information of organisms. Thus, closely related organisms have similar information on their DNA, usually indicated by similar nucleotide sequences.

Therefore, if dogs and wolves are more closely related in ancestry than dogs and foxes, the DNA sequence of dogs and wolves will be more similar than the DNA sequence of dogs and foxes.

Which is an effect of lower levels of solar radiation striking Earth?

Answers

Answer:

B) decreased rates of photosynthesis

Explanation:

Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.

They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.

[tex]6CO_{2} + 6H_{2} O + light ---> C_{6}H_{12}O_{6}[/tex][tex]+6O_{2}[/tex]

Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.

The exerpt states that movements in the Earth's crust (unbalance) causes Earthquakes. When it's balanced, there is no plate movement.

Answer: c

Explanation: if there is no plate movement that means that there is a balanced force there is nothing that is disrupting it. but if there's an earthquake in that means that there are unbalanced forces in that they cause an earthquake. a force is balanced if the two individual forces are of equal magnitude and of the opposite direction. And an object is said to be acted upon by an unbalanced force when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

Dr. Mrs. Brown has Rh+ blood, but her father is Rh-. What must her full blood type genotype be?

Answers

Answer:

Her full blood type genotype is Dd.

Explanation:

Rh (Rhesus) factor is a type of protein found on the outside of red blood cells. It is genetically inherited. An individual that has this protein is Rh-positive, and the one that doesn't is Rh-negative. The Rh-positive gene is dominant, while the Rh-negative gene is recessive. This means that a person must inherit at least one dominant (D) allele from their parents in order to be Rh-positive.

If Dr. Mrs. Brown is Rh-positive, and her father is Rh-negative, her mother must be Rh-positive (DD or Dd), as well. Her father has two recessive alleles (dd), which means that Dr. Mrs. Brown must have one recessive allele. Since she is Rh-positive, she must have one dominant allele. This makes her genotype Dd.

A. Extension
B. Abduction
C. Pronation
D. Adduction
In need of help!!!!

Answers

Answer:

If an agonist muscle produces a flexion, the primary action of the antagonist muscle will be extension.

Explanation:

Muscles are the organs of the musculoskeletal system that, through their contraction and relaxation, allow body movements.

Due to the location of each muscle in relation to the bone and joint, they can perform diverse movements, there being the so-called agonist and antagonist muscles for each movement.

If an agonist muscle makes a movement, the antagonist muscle or muscles will make the opposite movement, so the extension corresponds to the antagonistic action of the flexion.

The other options are not correct because:

    B y D. Abduction and adduction are antagonistic movements, not related to flexion.

    C. The antagonistic movement of pronation is supination.

The characteristics that protists and fungi both have that make them eukaryotes is the possession of a membrane bound nucleus and other organelles.

EUKARYOTES:

Eukaryotic cells are cells that possess a membrane-bound nucleus to house their genetic material (DNA). Eukaryotes also possess other membrane bound organelles like mitochondria, golgi apparatus etc.

This feature particularly differentiates them from prokaryotic cells. Eukaryotic organisms include plants, animals, fungi, some protists etc.

Therefore, it can be said that the possession of a membrane bound nucleus and other organelles is the characteristics that makes fungi and protists be considered eukaryotes.

Explanation:

Imagine you are studying a population of finches on one of the Galápagos Islands. You have been recording many of the birds' physical traits, including the length of both wings. You observe that for 80% of individuals measured, the length of the left wing is not significantly different from the length of the right wing (in other words, they are symmetrical). But for about 20% of birds measured, the wing lengths are asymmetrical. This distribution is true from generation to generation. Suddenly, a rare 5-day windstorm takes over the island. After the storm, you spend the next several days netting each bird on the island that survived the storm. You discover that 85% of the birds with symmetrical wings survived the storm, whereas only 5% of the birds with asymmetrical wings did.
a. Propose a hypothesis to explain this observation.
b. If such storms become increasingly common due to changes in climate, how might you expect the population to change over time with respect to wing symmetry? The distribution of symmetrical to asymmetrical will change so that close to 100% of birds will have symmetrical wingspans.

Answers

Answer:

a) The change in the character of an organism relies upon the ability of the adaption on the base of the external change or the environment change, "An organism that is not able to adapt accordingly would not survive and eliminated from the population."

b) In the given case, Symmetric wings are far more suitable for the survivorship as it provides better flight than the organism with asymmetric wings, it is also given that there is 20% of the population have asymmetric wings.

After the storm which is selection pressure, there is the elimination of the entire bird population with asymmetrical wings from the ecosystem so the final frequency would be 100% of the entire population with symmetrical wings.

Natural selection benefits the phenotype that increases the fitness. a) Symetrical wings increase the fitness of finches because they are better to face selective pressures. b) natural selection will favor symmetrical wings.

-------------------------------------

a) Hypothesis:

Symmetrical wings increase the fitness of finches because these type of wings are better to face selective pressures like severe windstorms.

b) If such storms become increasingly common with time, natural selection will favor symmetrical wings by increasing its frequency in the population, while animals with asymetrical wings will decrease to near cero.

Natural selection is an evolutive force that selects beneficial alleles and increases their frequency in the population.

It is the result of the phenotype-environment interaction which determines gene destiny in space and time.

Natural selection results in adaptation, which means the increase of the aptitude phenotype.

Aptitude is the contribution of each genotype to the next generation.  

Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.  

Adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.

The selective agent is the environmental trait that determines the differential survival of the phenotypic classes.

The environment influences the probability that each genotype passes its gametes to the next generation.

So in this example,

⇒ The strong storms are acting as selective pressures.

⇒ This selective pressure is modeling the phenotype of finches.

Natural selection favors the phenotype that performs better when facing storms.

⇒ Symmetrical wings are the phenotype that better suits and increases the animal's fitness.

⇒ Hence, natural selection favors this phenotype over asymmetrical wings.
