Answer:
B
Explanation:
A human cell in prophase of mitosis can be distinguished from a human cell in prophase I of meiosis by the presence of paired homologous chromosomes in the meiotic cell.
CELL DIVISION:
Cell division involves two processes namely: mitosis and meiosis. Mitosis results in two daughter cells that are genetically identical to one another. Meiosis, on the other hand, results in four daughter cells that are genetically different from one another. Mitosis and meiosis as types of cell divisions involves phases namely: prophase, metaphase, anaphase and telophase. The major difference between prophase of mitosis and prophase I of meiosis is that homologous chromosomes, which are similar but non-identical chromosomes from each parent, are paired.Learn more about prophase of mitosis and meiosis at: https://brainly.com/question/23718222?referrer=searchResults
Define organic evolution
Answer:
Organic evolution is the theory that more recent types of plants and animals have their origins in other pre-existing forms and that the distinguishable differences between ancestors and descendents are due to modifications in successive generations.
Explanation:
Answer:
Organic evolution is the theory that more recent types of plants and animals have their origins in other pre-existing forms and that the distinguishable differences between ancestors and descendents are due to modifications in successive generations.
Explanation:
What is an example of organic evolution? of Organic evolution produces genetic modifications in a species or inside a cluster of species with time. Examples of this phenomena are Evidence of missing links in Archaeopteryx, wings of birds and insects – analogous organs.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp

A student is asked to design an investigation which will cause an object to have motion that matches the graph she was given.
Which of the following investigations would yield results which match the graph? (DOK 3, AKS 8a)
O A The student will push a ball up a ramp and allow it to roll back down.
OB. The student will push a ball on a smooth, flat surface and then on a rough surface.
OC. The student will push a ball on a smooth, flat surface, it rolls at a constant speed for a short time and then down a rough hill.
D. The student will release a ball down a smooth hill, it rolls at a constant speed for a short time, and then rolls onto a rough surface.
The answer is A. The answer's A because the ball is still in motion.
Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determine the phenotypes of the F1 generation resulting from a cross between a heterozygous long legged, weak muscled horse and a heterozygous long legged, strong horse
Answer:
See the answer below
Explanation:
Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).
Heterozygous long leg, weak muscle = Llgg
Heterozygous long leg, strong muscle = LlGg
Llgg x LlGg
Offspring:
2 LLGg - Long leg, strong muscle
4 LlGg - Long leg, strong muscle
2 LLgg - Long leg, weak muscle
4 Llgg - long leg, weak muscle
2 llGg - short leg, strong muscle
2 llgg - short leg, weak muscle
Ratio of offspring with long leg and strong muscle = 6/16 or 3/8
Ratio of offspring with long leg and weak muscle = 6/16 or 3/8
Ratio of offspring with short leg and strong muscle = 2/16 or 1/8
Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

What brain structures regulate events in the ovaries and uterus?
Answer:
The Pituitary and Ovarian Hormones Control the Ovarian Cycle
Explanation:
FSH and LH stimulate ovarian follicles to grow. As the follicles grow, they begin to secrete estrogen. During this phase of the cycle, the increasing levels of estrogen feed back on the pituitary to inhibit the release of additional FSH and LH.

Which of the following does not describe hormones in the body? I’ll mark the correct answer a brainliest
A. they are mediator molecules released in one part of the body but regulating the activity of cells in other parts of the body
B. most hormones enter interstitial fluid and then the bloodstream
C. hormones acts on muscles and glands only
D. hormones exert their effects by binding to receptors on or in the "target" cells
I think its C. hormones act on muscles and glands only. Because hormones act on cells, tissues, organs etc. So this is incorrect and the rest of them are correct.
