The offspring resulting from pollinating a flower of one plant with the scraped-off flower of another plant will be genetically distinct from their parent (option c) .

When a botanist scrapes off a flower from one plant, it collects the pollen from that flower.

The botanist then uses the collected pollen to pollinate the flower of another plant, transferring the genetic material from one plant to another.

Pollination is the process by which pollen grains are transferred from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower.

During pollination, the pollen carries the genetic information (DNA) of the plant it came from.

When the pollen reaches the stigma of the second plant's flower, it fertilizes the ovules and initiates the formation of seeds.

The seeds that develop from this cross-pollination will contain a combination of genetic material from both parent plants.

Due to the mixing of genetic material, the offspring will be genetically distinct from either parent.

The specific characteristics of the offspring will depend on the traits inherited from each parent.

Genetic recombination and variation occur during sexual reproduction, resulting in offspring that exhibit a range of genetic traits.

Therefore, based on the process of sexual reproduction and genetic mixing through pollination, it can be concluded that the offspring will be genetically distinct from their parent.

Answer:

OJ. They stimulate maximum root and stem growth at different concentrations.

Explanation:

Looking at the graph found in the attachment below, conclusions can be drawn about the effect ofnthe difference in concentration of plant hormones in the two different parts of the plants under consideration, the roots and the stem.p

Considering the roots;

maximum growth of the roots of plants as seen by the upward curve ofbthe arrow, is obtained when plant hormones are at low concentrations. However, with increase in the concentration of plant hormones, the growth of root diminishes as seen bynthe downward slope of the curve.

Considering the stems:

At low concentration of hoeprmones, the growth of stem is very minimal. However, with increase in concentration of plants hormones, a rapid upward shoot is seen in curve indicating a rapid increase in growth. Maximum growth occurs at high concentration of plant hormones.

Therefore, the proper conclusion is that, plant hormones stimulate maximum root and stem growth at different concentrations.

Owing to the fact that the parent cell duplicates itself with the same number of chromosomes into the daughter cells then the daughter cell each have eight chromosomes.

The term cell division has to do with the process by which a cell is broken down to give daughter cells. The process of cell division is responsible for the growth of the organisms. There are two kinds of cell division and these are the mitosis and the meiosis.

While mitosis occurs in the body cells, meiosis occurs in the gamete cells of the organisms. We know that in mitosis, the cell duplicates the exact same number of chromosomes in the parent nucleus into the daughter nucleus hence the daughter nuclei both have eight chromosomes.

The correct answer is D. White hair of adult polar bears

Explanation:

Adaption refers to a natural process that involves a change in behavior or traits in a species or population to make this more suitable to survive. Indeed, adaptations help an organism to survive in a specific environment or adapt to changes. Besides this, adaptation is the result of processes such as natural selection through which more fit organisms survive and pass fitness traits to new generations.

According to this, the one that is an example of adaptation is the "white hair of adult polar bears" because this phenotype (visible trait) helps polar bears to camouflage in the Artic, in this way, polar bears can avoid possible predators and have more chances to hunt. This means, this trait makes polar bears more suitable to survive and due to this, it is an adaptation.
