1. Bees, flies, wasps, butterflies, and moths are significant insect pollinators. Moths are drawn to white flowers that are open at night, but bees and butterflies are drawn to brilliantly colored blooms with powerful scents that are open during the day.

The act of moving pollen grains from an anther to a flower's stigma is called pollination. Flowers that are pollinated by insects typically generate a sweet nectar that the insects visit to consume. If a flower is self-pollinating, fertilization occurs when pollen stock from an insect contacts the stigma of the bloom. If the bug is bisexual, it will fly to another bloom and disperse the pollen.

2. Most flowers advertise themselves by being brightly colored and perched on long stems so they wave in the air and are closer to where insects are flying, as opposed to on the ground, where they would otherwise be. A flower's petal sizes and shapes, in addition to color, can draw insects.

3. Flowers draw insects because of their aroma or vibrantly colored petals. Nectar is a delicious liquid that many flowers generate that is consumed by insects. The female part of the flower is the carpel.

Answer 2. Flowers that are pollinated by insects have characteristics that enable insects, birds, or other animals to pollinate them while consuming the nectar. When an insect brushes by the stigma of a flower, whether it is the same bloom or another, pollen grains will adhere to the insect's outer layer and stick to the flower's stigma, pollinating the flower. When the two seˣ cells combine, fertilization occurs, the ovule develops into a seed, and the ovary becomes a fruit. The pollen grain then grows a pollen tube down the style to reach the ovary, which contains the ovules.

Haploid Cells

Haploid cells contain only one set of chromosomes. Gametes or sex cells are the most common type of haploid cells. They are produced by meiosis and are genetically diverse. When the haploid cells from male and female fuse together during fertilization, it forms a diploid cell.

Diploid Cells

These cells have two sets of chromosomes. It is formed by the fusion of two haploid cells. Most mammals are diploid, i.e., they have two homologous copies of each chromosome in the cells. They are produced by mitosis. The somatic cells in humans are diploid cells.

The form of natural selection does the histogram show is disruptive selection.

In disruptive choice, choice pressures act on people withinside the center of the trait distribution. The end result is a bimodal, or -peaked, curve wherein the 2 extremes of the curve create their personal smaller curves.

Plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar in a process known as photosynthesis.

When performing photosynthesis, plants utilize the ambient carbon dioxide and release the oxygen gas they create into the atmosphere. Gas exchange is the term for this. Stomata, a unique part of the plant's leaf, are used to accomplish this. The guard cells that surround the stomata become turgid or flaccid in response to the entry or escape of water molecules, respectively. Stomata open and gas exchange occurs when the guard cells become turgid, or the other way around.

A botanist scrapes pollen off a flower of one plant and then uses it to pollinate the flower of another plant. What can be scientifically concluded about their offspring?

A. They will have a large amount of genetic variation.

B. They will have twice the number of chromosomes as their parents.

C. They will be genetically distinct from their parents.

D. They will be able to reproduce only asexually.

Plants' xenogamous system has high probabilities of introducing genetic variation between plants. Option A) They will have a large amount of genetic variation.

There are two general crossing systems in plants, which depend on pollination type.

Sexual reproduction gives more possibilities to different alleles of a gene that did not appear in one generation to express in the next generation.

Both types of pollination allow genetic variation, however by the occurrence of crossed pollination there are more chances to ensure the variability of the species and survival to environmental changes.

While by self-pollination there are more chances to express the same genotype of the parental plant.

The Xenogamous system has the advantage of avoiding the effects of endogamy in a population by increasing genetic variability.

In the exposed example, the botanist is acting as the pollinator agent, allowing one plant's pollen grain to fertilize the egg of the other plant.

The merging of these gametes will introduce variation since there will new allelic combinations.  

The correct option is A). They will have a large amount of genetic variation.
