Answer:
Sister chromatids found in each of the cells previously originating in meiosis I are separated during meiosis II.
Explanation:
Meiosis is the process of cell division used to obtain sex cells or gametes. Unlike mitosis, the daughter cells obtained in meiosis have half the chromosome charge, i.e. they are haploid.
The result of meiosis I is two haploid daughter cells, in which each chromosome is made up of two sister chromatids, still attached. During meiosis II, whose duration is short, the sister chromatids separate, and each cell will give rise to two haploid daughter cells.
The end result of meiosis I and II is four haploid daughter cells, which become gametes.

Answer:
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Of the 340 watts per square meter of solar energy that falls on the Earth, 29% is reflected back into space, primarily by clouds, but also by other bright surfaces and the atmosphere itself. About 23% of incoming energy is absorbed in the atmosphere by atmospheric gases, dust, and other particles. The remaining 48% is absorbed at the surface
Answer:
No.
Explanation:
Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.
Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.
<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>
Answer: A. Cool
Explanation:
The diagram shows that moving from the left to the right indicates a lower temperature and the arrow is pointing to stars to the right which means that they are cool in comparison to those on the left.
Red stars like the one being pointed to are the cooler stars with temperatures of less than 6,000 Kelvin as opposed to blue stars which are very much hotter and go above 10,000 Kelvin.
The answer is C) Increase genetic variation and breed plants to contain the wild variety.
