Anatomical and molecular features often fit a similar pattern due to Homology. Homology is the existence of shared ancestry between two structures or genes in a different species. 

A process that can cause this not to be the case is Convergent Evolution.
Convergent Evolution occurs when two unrelated species independently evolve similar traits to cope with evolutionary changes.

Appears to contain a multilobed nucleus. what is the most likely identity of the observed leukocyte?
Brrunno [24]

Neutrophil is the most likely identity of the observed leukocyte

<h3>What is Neutrophil ?</h3>

The most common type of granulocyte in humans are neutrophils, also known as neutrocytes or heterophils, which make up between 40% and 70% of all white blood cells. They are an essential part of the innate immune system, and they have different functions depending on the species.

The bone marrow-produced stem cells are differentiated into the neutrophil-killer and neutrophil-cager subpopulations. Due to their potential ability to access tissues that other cells or substances cannot, they have a limited lifespan and are very migratory. There are two different types of neutrophils: banded and segmented neutrophils (or bands). They belong to the same family of cells as basophils and eosinophils, which is known as PMNs.

You observe two populations of chimpanzees using sticks to dig termites out from nests for food. One population uses long sticks
icang [17]

Answer: B. The population using long sticks has mostly long sticks in its environment

Explanation:

Going back to the statement that reiterates the hypothesis after observations about the apes in the Introduction.

Reviewing the findings in this case, on the behavior of using sticks to dig seem to be the focus the experiment and choice length of the stick.

Making a judgment about whether or not the two finding has been supported is next step.

If there are equal numbers of short and long sticks in the environment of each population and the apes chooses one specific we can say their behavior is learned.

 If the chimpanzees using short sticks have made the the sticks short by breaking long sticks then we can say this behavior is learned.

When the Young chimpanzees in both populations start out using sticks of many different sizes we can see that these variables of learning is yet to be perfected.

When individuals in the population that don’t use the common stick length for that population catch fewer termites this reveals a randomness in the behavior of interest.

At this point we can say that if the population using long sticks has mostly long sticks in its environment then there is a biased objective in the study and this does not support the hypothesis that the choice of stick length is a learned behavior.

Mendel crossed plants that produced only round seeds to those that produced only wrinkled seeds. In the next generation, all the
Artist 52 [7]

Answer:

Dominance

Explanation:

Mendel discovered certain principles that governs heredity or inheritance when he conducted experiments. In his experiments, he discovered that an organism receives two copies of a gene called allele, from each parent.

He discovered that one allele of a gene has the ability to mask or suppress the expression of its allele variant in the same gene. He called the allele that masks or is expressed, DOMINANT allele, while the allele that is masked, RECESSIVE allele. Based on this observation, he named his first principle, LAW OF DOMINANCE.

In this case, he crossed a purebreeding round-seeded pea plant and a purebreeding wrinkled-seeded pea plant, he noticed that in the F1 generation, all the offsprings possessed round seeds. This led to the conclusion that the allele for round seeds masks the phenotypic expression of the wrinkled allele in a heterozygous state. Hence, the allele for round seeds is dominant while the allele for Wrinkled seeds is recessive.
