a
100% pink
b
75% pink
c
50% pink
d
25% pink
e

Answer:
A = 100% Pink
Explanation:
It’s Simple
A cross between two pink flowering fruitloops would result in a 50% or 1/2 chance of producing pink offspring in the progeny of the hybrid.
What is incomplete dominance?Incomplete dominance is the consequence of a cross between two organisms in which both parental contributions are genetically distinct. This form of cross produces offspring with a phenotype that is intermediate. There are a few different names for what is known as "incomplete dominance," including "semi-dominance" and "partial dominance." Mendel described dominance but not incomplete dominance.
WW - white
RR - Red
WR - pink
Two pink flowers are crossed:
WR x WR
WW WR WR RR
Offspring:
1/4 WW - white
2/4 WR - pink
1/4 RR - red
Therefore, cross between two pink flowering fruitloops would result in a 50% or 1/2 chance of producing pink offspring in the progeny of the hybrid.

How does latitude affect climate?
Answer:
Temperatures drop the further an area is from the equator due to the curvature of the earth
Explanation:
Answer:
Explanation:
Temperatures drop the further an area is from the equator due to the curvature of the earth. In areas closer to the poles, sunlight has a larger area of atmosphere to pass through and the sun is at a lower angle in the sky.As latitude increases, the sun shines more obliquely and provides less warming energy.

What are convection currents?A process that involves the transfer of energy from one location to another is a convection current. It is also known as heat transfer by convection.
Convection currents are fluid movements brought on by temperature or density variations within a substance. Because the particles within a solid are fixed in place, convection currents are only visible in gases and liquids. A straightforward illustration of convection currents is warm air rising toward a home's ceiling or attic.
Therefore, the correct option is
A. Conventional currents in the Earth's mantle.

what is the right term of bacterial chromosome: a)nuclear material b)plasmid c)message d)nucleus
Answer:
B) Plasmid
Explanation:
Plasmids are the correct terms to call bacterial chromosomes by.
These plasmids are the chromosomal DNA which prokaryotes, like bacteria, have.
This is because they do not have nuclei, which eukaryotes do. This makes answer choices A and D wrong because they involve the nucleus.
Answer choice C is also wrong because it is not the term to call bacterial chromosomes, although plasmids do contain messages.
So, answer choice B is correct.
In the Old field mice example scientists found variation in fur color ranging from light to dark brown. One might think they are not the same species because they are so different in appearance. But the early scientists actually brought live mice to the lab, some with dark fur, some with light, and found that he could successfully breed them in the lab, suggesting that were the same species. What species concept best applies to this situation.
Answer:
Specie is a group of organisms that can interbreed with one another and produce fertile offspring.
Explanation:
Species Concept that applies to this situation is that a specie is a group of organisms that can interbreed with one another and produce fertile offspring. According to the example of mice, we can conclude that species having different appearance if belongs to the same group so it can interbreed with one another and produce offspring which is fertile and continue its generation.

How do adaptations help an
organism as they struggle for
existence?
Answer:
adaptations are the development of new characteristics that improve the survival and fitness of an organism. these adaptations comes from either mutation or recombination.
those organisms which have adapted can better survive and compete with the other members of population. in case of any disastrous change only those survive which have been adapted all others will die. these adaptation increase their struggle for existence.

A model showing two possible arrangements of chromosomes during meiosis is shown in Figure 1.Figure 1. Two possible arrangements of chromosomes during meiosis
Which of the following questions about genetic diversity could most appropriately be answered by an analysis of the model in Figure 1?
A) Does crossing-over generate more genetic diversity than the fusion of gametes does?
B) Does DNA methylation prevent independent assortment during metaphase II?
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
What is independent assortment?Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.
This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.

A kind of reproduction involving one parent animal
A kind of reproduction involving one parent animal is called asexual reproduction, as there is no crossing of the genes and, due to the absence of sexual reproduction, the single parent is involved.
What is the significance of the offspring of asexual reproduction?Asexual reproduction is a kind of reproduction where there is no need for the involvement of the two parents, such as in sexual reproduction, where there is the involvement of one male and one female, but this is absent in asexual reproduction. Asexual reproduction leads to the formation of identical offspring without any uniqueness.
Hence, a kind of reproduction involving one parent animal is called asexual reproduction, as there is no crossing of the genes and, due to the absence of sexual reproduction, the single parent is involved.

List down the major actions that lead daughter cells to be different from parents cells meiosis?
Answer:
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.
Explanation:
9. How do the chromosomes of a daughter cell compare to the chromosomes of a mother cell?
The daughter cells have n chromosomes. The mother cell has 2n.
The daughter cells have the same type of chromosomes, but a different number
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Answer:
The daughter cells are identical to the mother cell.
The daughter cells have twice as many chromosomes as the mother cell.
Explanation:
Daughter cells are identical means same shape and structure to the parent cells because the parent cell is divided equally and as a result daughter cells are produced. In mitosis cell division, two daughter cells are produced having double number of chromosomes just like parent cell, whereas in meiosis cell division, four daughter cells are produced having half number of chromosomes.
