A plant was placed in water containing black dye. After 24 hours the
plant was removed and sections were taken from the root and the
stem. In the root, cambium part will get stained and in the stem, cortex will be stained from dye so the correct option is D.
What is cambium and cortex in plant root and stem?Cambium is a layer of continuous dividing cells between xylem and phloem tissues which is responsible for the secondary growth of stems and roots. A cortex is an outer layer of a root or stem in a plant, located below the epidermis but outside of the vascular bundles.
The conduction (uptake) of water in a plant stem takes place through the xylem.

Distinguish how an animal welfare activist would most likely feel about the animals’ housing and training in the following scenario.
A traveling circus uses a number of animals in its act, including a tiger and a small herd of elephants. When traveling, the tiger gets its own car and attendants who feed it regularly. The elephants are dispersed among three cars and each has a number of attendants who feed and clean up the elephants’ waste. To train the animals, the circus hires animal trainers who use whips to teach the animals how to behave in the ring.
Answer:
using whips on animals is not a desirable activity, as well as circus' being notorious for the mistreatment of animals, I think anybody who had these animals welfare in mind would disapprove of this scenario

If the membrane was completely permeable,the concentration inside the cell would be about the same as the outside. Give reason?
If the cell membrane is permeable to some solute, this means the solute is free to move in or out of the cell, depending on its concentration gradient. The solute will move by diffusion from the area with high concentration to the area with low concentration. So if the concentration of this solute is higher outside of the cell compared to the inside, then it will move into the cell until its concentration is equal on both sides.

Ddt was widely used as a pesticide for 20 years. Its use was banned after studies showed severe side effects were evident in humans, the environment, and animals as a result of ddt. Which reason best explains why the side effects of ddt were so harmful?.
Answer:
One major side effect of DDT was the extreme damage to bird populations. DDT caused the shells of bird eggs to become extremely thin, which made them prone to breaking from minor disturbances and failing to thrive due to temperature regulation issues. It also slowly poisoned animals, especially birds that fed on insects that were poisoned by DDT. A notable bird species that was affected by DDT is the bald eagle. At one point in the 1960s, bald eagles nearly went extinct due to various effects of DDT. The threat of one of the most recognizable animals in America going extinct led to lawmakers trying to ban DDT.
Research has suggested that the burning of fossil fuel has had to change in the carbon cycle causing an increase in carbon store in the atmosphere. Determine how much less carbon would need to be realesed by burning fossil fuels in order for the amount of carbon stored in the atmosphere to not increase.
The carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.
What are fossil fuels?Fossil fuels (e.g. coal) are different types of fuels obtained from fossils, which release carbon dioxide into the atmosphere when they are burned.
Carbon dioxide (CO2) is a gas that has a greenhouse effect and thus can produce climate warming.
In conclusion, the carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.

What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
What is crossing over?Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.

What is a zygote and how is it formed
Answer:
A zygote is a fertilized ovum. The germ cells undergo meiosis to reach a haploid state (n) as part of spermatogenesis and oogenesis. The sperm and the unfertilized ovum reinstates a chromosome set in zygote in a diploid state (2n).
After fusing with the sperm, the second stage of meiosis takes place for separation of chromatids. Post-fertilization, mitosis of the zygote is initiated which develops into a mature offspring exhibiting characteristics of its parent.
Explanation:
The zygote stage development occurs in the first week of fertilization. The genome of the zygote is the combination of DNA in each gamete and contains all the genetic information required to form an individual.
Answer:
Zygote is a diploid cell resulting from the fusion of two haploid gametes
