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

based on the data, what can you infer about the relative pH of the stomach?
The pH of stomach is important as it helps to induce the digestive enzyme called pepsin. The presence of HCL i.e., hydrochloric acids in stomach results in the pH of stomach to become acidic which range from 1.5 to 6.5 values.
What is the pH level of stomach?When the bolus enters the stomach, it aids the release of gastric juice having enzymes, mucous and HCL.
The upper and lower parts of stomach have varying pH values. Upper part has a pH of 4−6.5, while the lower part is with a pH of 1.5−4.0 which is highly acidic due to HCL.
Thus, the relative pH of stomach is acidic ranging from value 1.5 to 6.5.

The diagram represents several stages of the cell cycle.

During the cell cycle, normal cells exit the G1 phase and enter the Go phase where they rest. Typically,
cells will reenter the cycle at G1 prior to going on to S phase. However, abnormal cells such as cancer
cells, may not be allowed to enter the Go phase to rest.
As a result, these cells will most likely -
F. mutate during G2 phase
G. continuously repeat the cycle
H. die after DNA replication
J. fail to complete mitosis
Abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
The abnormal cell undergoes a repeated cell cycle because they express an enzyme called telomerase that switches the wearing down of chromosome ends.
This happens normally in the cell cycle, and after multiple repeated cycles, such abnormal cell undergoes apoptosis.
Therefore, abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.

why farmers are manuring at the roots of the plant
Answer:healthy plants
Explanation:the farmers use raw manure on their fields because it is an excellent source of nitrogen (N), phosphorus (P) and potassium (K), which are all nutrients necessary for plants to grow and thrive.
Answer:
The reason why farmers put manure at the roots of the plants is because that is how most of the nutrition is taking up into the plant. Most of the minerals in the earth are absorbed into the plant for usage by the roots which is why the manure would be placed where the roots are. However, it's important to not put too much because that can actually cause the roots to get burned because there is too much minerals so it's important to keep a balance.

what kind of mutation does this image represent
Answer:
A. Deletion
Explanation:
The kind of mutation that this image represent is deletion. The correct option is A.
What is mutation?A variation in the usual DNA sequence at a specific gene locus. Although the term has a negative connotation, mutations (including polymorphisms) can have a negative, positive, or neutral effect on cell function.
Mutations can occur as a result of errors in DNA replication during cell division, mutagen exposure, or viral infection.
Germline mutations (those found in eggs and sperm) can be passed on to offspring, whereas somatic mutations cannot.
In genomics, a deletion is a type of mutation that involves the removal of one or more nucleotides from a segment of DNA. A deletion can result in the loss of any number of nucleotides, ranging from a single nucleotide to an entire chromosome.
Thus, the correct option is A.
