Answer:
This question is incomplete
Explanation:
This question is incomplete but there are some general facts that can be made.
Firstly, mitosis only occurs in meristematic tissue of plants which includes apical and lateral meristems
There are 4 phases in a cell cycle
1) G1 (gap 1) phase: This is the first phase of the cell cycle that has to do with an increase in the size of the cell. Major cellular components duplicate in size here.
2) S-phase: DNA replication occurs here.
3) G2 (gap 2) phase: This is the gap phase that comes after the S-phase. The cell undergoes further growth here and the organelles of the cells are also prepared for cell division.
4) Mitotic phase: There are four stages here
i) prophase: Chromosome condenses and becomes visible at this stage. And there is the emergence of spindle fibre from centrosomes.
ii) metaphase: Spindle fibre develops and sister chromatids are attached to
separate spindle.
iii) anaphase: Cohesin, which holds two sister chromatids (of chromosomes) together, breaks down and are pulled towards opposite poles.
iv) telophase: Chromosomes begins to decondense at opposite poles and actual cell division starts as mitotic spindle breaks down.

B)As annual precipitation increases, the populations of Species A and B decrease.
C)As annual precipitation increases, the population of Species A increases while Species B decreases.
D)As annual precipitation increases, the population of Species A decreases while Species B increases.
Part B If the precipitation levels observed in year '09 remain the same and other resources remain constant, identify and describe what can be predicted to occur with the population of Species B over the next 6 years? Enter the answer in the box.
The claim is best supported by the data is as annual precipitation increases, the populations of Species A and B decrease. Thus, option B is correct.
As annual precipitation increases, the populations of Species A and B decrease. As annual precipitation increases, the population of Species A increases while Species B decreases. As annual precipitation increases, the population of Species A decreases while Species B increases.
As annual precipitation increases, the populations of Species A and B increase. As annual precipitation increases, the population of Species A decreases while Species B increases.
If the precipitation levels observed in year '09 remain the same and other resources remain constant, identify and describe what can be predicted to occur with the population of Species B over the next 6 years.
Therefore, The claim is best supported by the data is as annual precipitation increases, the populations of Species A and B decrease. Thus, option B is correct.

Explanation:
Mimicry refers to the resemblance of organisms of two different species with respect to structural, behavioral or physical features. Mimicry helps a defenseless species (mimic) to protect itself against predation due to its resemblance to the aggressive and dangerous species (a model).
For example, harmless king snake mimics venomous coral snake to avoid the predators. It represents the Batesian mimicry.
In other cases, predators may use mimicry to catch their food organisms. In Mullerian mimicry, two or more harmful species resemble each other.
An organism's capacity to mimic another organism, item, or environmental aspect is known as mimicry, hence option D is correct.
Predator avoidance: Some animals imitate the looks of other, more deadly species to frighten off predators. For instance, the viceroy butterfly imitates the poisonous to predators monarch butterfly.
Adapting to a different species: In order to blend in and avoid being noticed, some animals mimic the look of other species. For instance, the peppered moth imitates lichen-covered bark to help it fend off predators.
Catching prey: To draw in prey, several creatures replicate the appearance of food. The angler fish, for instance, employs a bioluminescent bait to entice small fish.
Thus, option D is correct.

Fossils of sea creatures have been found on land thousands of miles from any ocean.
Answer:
The correct answer would be c. pupil.
Pupil refers to the adjustable opening present at the center of the iris.
It appears as a black hole present at the center of the eye through which light is passed into the eye.
The iris is muscular and contractile structure present around the pupil.
The pupil regulates or controls the amount of light entering the eye with the help of iris.
Iris through its contractile nature regulates the size of the pupil and thus, it controls the amount the light passing through the eye.
The adjustable opening in the center of the eye controlling light entry is the pupil, with size adjustments regulated by the iris.
The adjustable opening in the center of the eye that helps control the amount of light entering the eye is called the pupil. This integral part of the eye widens or narrows to allow more or less light to enter, respectively. The pupil's size is regulated by the surrounding muscle structure, the iris, which adjusts depending on the intensity of light present. Unlike the cornea and fovea, which have different roles, the pupil specifically controls light entrance.
