In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). A black male guinea pig is mated to a white female guinea pig. The offspring were 7 black and 6 white guinea pigs. What are the genotypes of the parents?

Answers

Answer 1

Answer:

Male: Bb

Female: bb

Explanation:

1. I made punnet squares to test each genotype pairs:

BB (black male) x bb (white female)

Bb (black male) x bb (white female)

** B is dominant over b so if Bb, black will be expressed

3. I calculated the percentage of each phenotype to see if it matched the the number of white and black guinea pigs produced. I found that Bb x bb had 50% chance for white guinea pigs and 50% chance for black guinea pigs, which is about the same in the scenario above (7 black, 6 white).

4. I infered that the male black guinea pig's genotype is Bb and the female white guinea pig's genotype is bb.

In Guinea Pigs, The Allele For Black Fur (B) Is Dominant Over The Allele For White Fur (b). A Black Male

Which statement accurately describes the scenario?

Answers

According to the given situation, the fish experienced an evolutionary change because of genetic drift.

What is genetic drift?

Genetic drift is the change in the frequency of a present gene variant or allele in a population due to random chance.

Genetic drift may cause gene variants to disappear completely and thereby reducing genetic variation and also causing rare alleles to become much more frequent and evenly fixed.

The Atlantic puffin feeds on several different species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed primarily on the types of fish shown in the graph below. The beaks of this group of puffins are shaped to grasp species A particularly well because it is the main species of fish in the ocean around this island. Suppose a puffin in this population is born with a shorter beak that cannot effectively grasp Species A. Predict what would happen to this bird. Explain your reasoning based on what you know regarding genetic adaptations.

Answers

The population of the Atlantic puffin will decrease because of inability to obtain food.

What is mutation?

A mutation is an abnormal change that occurs in the sequence of nucleotides in a DNA molecules of an organism.

Assuming a mutation occurs in the beak of the Atlantic puffin that affects it ability to eat fish species A.

Since, species A is the most abundant fish species, the population of the Atlantic puffin will decrease because of inability to obtain food.

Which part of fried shrimp provides the most energy in the form of glucose to help power cellular respiration

Answers

Answer:The breading on the shrimp

Explanation:

A part of fried shrimp that provides the most energy in the form of glucose to help power cellular respiration is known as the breading on the shrimp.

What is Cellular respiration?

Cellular respiration may be defined as a biological process that significantly leads to the production of energy in the form of ATP by the disintegration of glucose which we get from food molecules and oxygen.

The reactants of cellular respiration are oxygen and glucose while the products are carbon dioxide, water, and energy in the form of ATP.

The part of food products that power the process of cellular respiration must be highly rich in glucose in order to deliver as much as energy can possible.

So, the breading on the shrimp provides the most energy in the form of glucose to help power cellular respiration.

Therefore, the breading on the shrimp is a part of fried shrimp that provides the most energy in the form of glucose.

According to scientific thought, when does one species of organisms become two species? Question 2 options: when populations become separated from one another when one population becomes extinct when populations compete for the same resources when one population cannot interbreed with the other population.

Answers

According to scientific thought, the correct option to this is when does one species of organisms become two species When populations compete for the same resources as one population.

When one population cannot interbreed with another then it is called speciation. For example, if a cross between fertile and infertile is produced.

What is the evolutionary procedure of speciation?

The evolutionary procedure of speciation is how one populace of a species modifications over the years to the factor wherein that populace is awesome and might now not interbreed with the “parent” populace. Often a bodily boundary divides the species into two (or more) populations and continues them from interbreeding.

Hence clear it is that populations compete for the same resources when one population.

I need a lab report done about natural selection about birds and their beaks

Answers

search up what your looking for after you find one copy and paste it and go back and edit the report in your own words so it looks like you didn’t plagerize

Answer:

Natural Selection for the Birds

Purpose:

To determine which birds with which beaks survive best in their environment depending on the type of food available.

Question:

What is the effect of the type of food available on the frequency of different types of bird beaks? Hypothesis:

If the food type changes in the environment, then the amount of each type of bird beaks will change because birds with beaks more suited to the available food will be more successful over time.

Variables:

The independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks.

Materials:

100 sunflower seeds

100 raisins

100 grains of rice

2 forks

2 spoons

2 knives

Plastic cup

Procedure:

1. Gather around the edge of the table cloth, mixing the three groups fairly evenly.

2. Pick up food pieces only with your tool, using the pair of utensils in one hand, simulating the action of a beak.

3. Pick up one piece of food at a time, and put it in your cup (“stomach”) before picking another piece of food.

4. Keep your body off the table cloth and pick up food only within your reach.

5. Start only when the teacher says “Go” and finish when all food has been “eaten.”

Conclusion:

In this lab I learned about how favorable traits are important when nature selects what organism will survive and pass down its genes for the next generation to inherit, I also learned that most species learn to adapt to their environments so that they can have a favorable trait to be able to survive in their environment. I was able to observe that in the wilderness you need that favorable trait so that you are able to reproduce and pass down your genotypes for the next generation of you species to inherit. I gained useful skills such as how to determine the next generation’s population by analyzing results from experiments I conducted relating to the bird populations

The five essential elements for a viable habitat include food, water, cover, and what other two elements?.

Answers

The other two elements are Space and arrangement!!

The five essential elements for a viable habitat include food, water, cover, and the other two essential elements for a viable habitat are Space and Arrangement of resources.

4. Space: Sufficient space is necessary to support the population of organisms living in the habitat. Different species have different space requirements for their survival, breeding, and other activities. Having enough space ensures that individuals can find the resources they need and reduces competition for limited resources.

5. Arrangement or Arrangement of Resources: The arrangement or structure of the habitat is crucial for the organisms that live there. The spatial distribution of resources, such as food, water, and shelter, affects the accessibility and availability of these resources to different species. The arrangement can also impact predator-prey interactions, nesting sites, and overall ecosystem dynamics.
