Answer:

Cell divison is defined as the process in which a parent cell split into two or more daughter cells. There are three stages of cell division that includes interphase, mitosis/meiosis and cytokinesis.

In the interphase the proteins, enzymes and cell organelles are formed and at the end of this phase single strand chromosome becomes a double strand carrying genes.

In the meiosis (in sexual reproduction) or mitosis (asexual reproduction) phase, divison of nucleus takes place. Meiosis gives rise to geneticaly different cells due to crossing over while mitosis leads to identical cells .

Cytokinesis occurs cocurrently after meiosis or mitosis in which cytoplasm of a parental cell divides into two daughter cells each with identical chromatin.

Creation of new animals are also undergo these 3 stages of cell division that is interphase, meiosis (eukaryotes)/mitosis (prokaryotes) and cytokinesis. Majority of animals (eukaryotes) undergo meiosis phase because their mode of reproduction sexual and have genetic variation due to crossing over of chromosomes and produces 4 daughter cells at the end cell division.

Hence, the 3 stages of cell division is similar to craetion of new animals.

4) Study the wings of the birds in the two images below. Which of the following words applies to only one of the wing structures

Pani-rosa [81]

Answer:

The answer is A) Homologous structures

Explanation:

Homologous Structures:

Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.

Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
Inherited and developmental are out of context in terms of evolutionary relationships.

What characteristics do mutations have ?

aliya0001 [1]

Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.

In the apple maggot fly, rhagoletis pomonella, the frequency of certain alleles increases steadily as one goes from north to sou

sveticcg [70]

In the apple maggot fly, the frequency of certain alleles increases steadily as one goes from North to South. This is an example of: Sympatric speciation.

Sympatric speciation is observed when there are no physical barriers which prevent any members of a species from mating with another, and all members are in close contact to one another. A new species, possibly established on a distinct food source or trait seems to develop instinctively.

The example of apple maggot fly supports a model for sympatric speciation in progress. Hawthorn is the native host for the apple maggot fly in North America. However, in the mid-1800s, a new population developed on introduced, domesticated apple.
