Q4: Describe how crossing over can lead to new variations in genes. ​

Answers

Answer:

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

Which tree above shows a different evolutionary history from the others? Explain your answer.[ ]

Answers

Answer:

the second one is the right answer

The second evolutionary tree (2) is showing a different evolutionary history from the other trees.

What is an evolutionary tree?

An evolutionary tree is a diagram/graphic used in biology to show evolutionary relationships between taxa.

The taxa located at the tree can be different species, genera, orders, etc.

An evolutionary tree is monophyletic when all descendants originated from the same ancestor.

In conclusion, the second evolutionary tree is showing a different evolutionary history from the other trees.

Labrador retrievers are traditionally black, brown, or yellow. The B allele codes for black fur, and the b allele codes for brown fur. The E allele allows the pigment to be deposited in the fur, while the e allele doesn't allow the pigment to be deposited. If one lab has the genotype bbee, and another lab has the genotype BbEe, what is the chance that an offspring will be brown

Answers

Answer:

25% of offspring will be brown

Explanation:

4 out of 16 of will be brown

Sort the sentences based on the type of relationship they describe. Sea lampreys hatch eggs on fish and feed on the fish. Clown fish help sea anemones catch prey while using the sea anemones for protection. Mosquitoes suck blood from the bodies of organisms. Ants provide protection to acacia trees while receiving nutrients from the trees. Mutualism Parasitism Ants reserved PLZ HELP ​

Answers

Answer:

1: Parasitism

2: mutualism

3: parasitism

4: mutualism

Explanation: Hope this helps and have a great day!!

The sentences describe different types of symbiotic relationships between organisms are: Parasitism, Mutualism, Commensalism

1. Parasitism: Sea lampreys hatch eggs on fish and feed on the fish.

In parasitism, one organism benefits (the sea lampreys) at the expense of the other (the fish) by feeding on its tissues.

2. Mutualism: Clownfish help sea anemones catch prey while using the sea anemones for protection.

This sentence describes mutualism, where both clownfish and sea anemones benefit from the relationship. Clownfish protect sea anemones from predators, while they, in turn, provide a safe haven for the clownfish.

3. Parasitism: Mosquitoes suck blood from the bodies of organisms.

Mosquitoes exemplify parasitism as they feed on the blood of other organisms, taking nutrients without providing any benefit in return.

4. Mutualism: Ants provide protection to acacia trees while receiving nutrients from the trees.

This sentence represents mutualism, where ants defend acacia trees from herbivores, and in return, they receive nutrients and shelter from the trees.

5. Commensalism: Ants reserved.

The term "reserved" here seems to be incomplete, but assuming it refers to ants residing in a certain place, it would represent commensalism. Commensalism describes a relationship where one organism benefits, and the other is neither helped nor harmed significantly.

In summary, the sentences describe mutualism, parasitism, and possibly commensalism, showcasing the diverse interactions that can occur in ecological communities.

What characteristic could provide a species with a better chance of surviving a drastic environmental change?

(A) A small population size

(B) A highly diversified gene pool

(C) specialized cells within the body

(D) Many individuals with the recessive trait

Answers

the answer is B


Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.

A highly diversified gene pool could provide a species with a better chance of surviving a drastic environmental change. So, the correct option is B.

What is Diversified Gene pool?

Greater genetic diversity within a population is made possible by a diverse gene pool, which raises the possibility that at least some members of the population will exhibit features that are more adapted to the new environment.

This variety can develop as a result of gene flow from other populations or mutations. The number of people having the recessive trait or a limited population size, however, would not always give an advantage in enduring environmental change. A species may have a better chance of surviving a severe environmental shift if its gene pool is extremely varied.

Therefore, the correct option is B.
