The outcome of P generation in Mendel's experiment is that all of the plants in the F1 generation had purple flowers, none of them had white flowers.

Mendel began by experimenting with a single pea plant trait at a time. He started with a flower's color. Mendel cross-pollinated white and purple flowered parent plant. The P (for parent) generation refers to the parent plants in the tests.

The P generation's offspring are referred to as the F1 (for filial, or "offspring") generation. The F1 generation of plants all had purple flowers. They were all devoid of white blooms. Mendel questioned what had become of the white-flower trait? He assumed that white flowers are produced by some sort of inherited factor, and purple blossoms are produced by another type of inherited factor.

Explanation:

The descriptions that apply to the ribosome is a cellular structure that is composed of both RNA and protein.

All cells contain ribosome, which are macromolecular organisms that carry out biological protein synthesis (mRNA translation). To create polypeptide chains, ribosomes combine amino acids in the order dictated by the codons of messenger RNA (mRNA) molecules. The short and big ribosomal subunits are the two main parts of ribosomes. Each subunit is made up of numerous ribosomal proteins and one or more ribosomal RNA (rRNA) molecules (RPs or r-proteins). The translational apparatus also refers to the ribosomes and related components. A messenger RNA chain is produced from the DNA sequence that specifies the order of the amino acids in a protein. Messenger RNAs are bound by ribosomes, which use their sequences to determine the proper arrangement of amino acids to produce a specific protein. Transfer RNA (tRNA) molecules choose which amino acids to transport to the ribosome and then bind to the messenger RNA chain via an anti-codon stem loop. There is a specific transfer RNA that must precisely match the anti-codon of each coding triplet (codon) in the messenger RNA and carries the appropriate amino acid for incorporation into a developing polypeptide chain. After the protein has been created, it can fold to create a useful three-dimensional structure.

Answer:

An increase in sweat gland activity an increase in blood flow to the skin.

Explanation:

When the body temperature is abnormally high, thermoregulatory homeostasis is maintained by sweating and vasodilation.

Sweating:

This is a mechanism by which the body cools itself through the evaporation of water from the skin .Water is removed in form of sweat. As sweat evaporates, it removes heat from the body, which helps to lower the body temperature by cooling effect.

Vasodilation:

This  is a mechanism by which blood vessels in the skin dilate, allowing more blood to flow to the surface of the skin. This helps increase the amount of heat that is dissipated from the body, hence lower the body temperature. Also this increase in blood flow brings more oxygen to the cells of the body, which is important for maintaining proper metabolic function.#SPJ4

If the dna content of a diploid cell in the g1 phase of the cell cycle is x, then the dna content of a single cell at metaphase of meiosis ii would be same (x)

The G1 phase of the cell cycle immediately follows the cytokinesis stage of mitosis. Meiosis involves two divisions, Meiosis I and Meiosis II. Meiosis I sees the division of a diploid germ cells into two diploid daughter cells. Meiosis II sees the division of these diploid daughter cells into four separate haploid gametes.

In humans, a cell prior to meiosis I has 46 chromosomes which are each replicated to divide into two daughter cells, each of which will also possess 46 chromosomes. These chromosomes are then arranged and pulled apart to be split into two haploid gametes by the end of meiosis II. As the diploid cells don't divide into haploid gametes until cytokinesis in meiosis II, the cells would still be diploid in the metaphase II stage that occurs before this and therefore have an equal number of chromosomes, x, to a diploid cell in the G1 phase of the cell cycle.

If the genes used to synthesize these enzymes were mutated. These cells may continue to divide unchecked, resulting in tumor growth.

During development, apoptosis gets rid of cells, gets rid of cells that could be cancerous or infected with a virus, and keeps the body in balance.

Apoptosis is intervened by proteolytic compounds called caspases, which trigger cell demise by severing explicit proteins in the cytoplasm and core. Caspases are present in all cells as inactive precursors known as procaspases. These procaspases typically become active when they are cleaved by other caspases, triggering a proteolytic caspase cascade.

A p53 protein that is less effective at controlling cell proliferation is the result of these mutations. In particular, cells with damaged or mutated DNA cannot undergo apoptosis. DNA damage can therefore accumulate in cells. These cells may continue to divide unchecked, resulting in tumor growth.

Mendel began by mating a purple-flowering plant that was true to breed with a white-flowering plant that was true to breed. All of the blooms in the F1 generation were purple. The F2 generation, which was produced by the self-pollination of F1 plants, has 25% white flowers and 75% purple blooms.

Mendel started his research by cultivating plants that were true-breeding for a specific characteristic. When self-pollinating, a true-breeding plant will always give birth to offspring with that characteristic. A plant with yellow seeds, for instance, will always have progeny with yellow seeds. Mendel created these plants by allowing plants with just one characteristic, such white flowers or purple flowers, to self-pollinate over a long period of time. He let this go on until he was certain that the plants' progeny always possessed only one characteristic—in this case, either purple flowers or white flowers.

Correct answer is :- Cell membrane or plasma membrane.

A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that are harmful as well as nutrients into the cell. Another is that there will be proteins on the cell's membrane, which is its plasma membrane, that interact with other cells. Those proteins can be glycoproteins, meaning there's a sugar and a protein moiety, or they could be lipid proteins, meaning that there's a fat and a protein.

The body or structure of any living organism is made up of cells. These cells are also responsible for carrying out all the biological functions and regulations in the organism. Because of these features, the cell is called a living and working system.

The cell is the most important part of our body. Each organ in our body is made up of cells. Cells divide and multiply to make new organs and gates.

Cell is called as active living unit due to following reasons-

Always remember that, Cell is called as a living and functional system because living organisms/organisms consist of cells and all the physiological, biochemical, genetic and metabolic functions are carried out in the cell. It is believed to be the smallest functional unit that can exist independently.

The largest cell in the human body is egg. An ovum is also known as an egg cell and is a cell in the female reproductive system. Ovum is believed to be 20 times larger compared to sperm cells.

Remember, the Cell has the ability to live on its own and can perform all the functions that are important to a living being. A cell can do nutrition, respiration, transport, excretion, and reproduction just like an organism does.

Temperature plays an important role in determining the type, adaptation and distribution of plants in the organism. For example the arctic tundra does not have much vegetation while the tropical rainforests have evergreen trees, evergreen trees shed their leaves to avoid winter while tropical rainforests have same needle shape. The drier savannas and tropical grasslands, on the other hand, have short grasses that can survive the heat.

Rainfall is characteristic of tropical forests due to the temperature range of [tex]$20^{\circ} \mathrm{C}$[/tex]  to [tex]$34^{\circ} \mathrm{C}$[/tex] Precipitation is higher in tropical forests compared to savannas.

So option A is incorrect.

The climate is cold in the Arctic and Antarctic belts, so the temperature is always below [tex]$0^{\circ} \mathrm{C}$[/tex] in the arctic tundra, because these arctic tundra climates are frozen almost all year round.

So choice B is incorrect.

Climate change occurs in tropical climates throughout the year. These climate changes are associated with hot and cold seasons because it has a unique growing season. These kinds of temperature differences are not there in the savannas.

So choice D is incorrect.

Savannas have a shorter dry season than any terrestrial biome. The dry and hot climate makes the leaves, grasses and trees live for a long time, because only grass can grow during the year and there are no large plants.

Strain is the muscular injury may vary in severity from localized cellular injury to complete rupture of the muscle belly/tendon.

A strain to a muscle or muscle tendon is the same as a ligament sprain. Muscle strain occurs when muscle fibers cannot deal with the demands imposed on them by exercise overload, resulting in fiber tearing.

It is a contraction-induced injury that causes muscle fibers to break as a result of excessive mechanical stress. This is usually caused by a strong eccentric contraction or overstretching of the muscle. As a result, it is common in non-contact sports with dynamic qualities like running and leaping.

Grade I (mild) strains impact only a small number of muscle fibers. There is no loss of strength, and the range of motion is fully active and passive. Pain and soreness are frequently postponed till the next day.

In Grade II (moderate) strains, about half of the muscle fibers are ruptured. Acute and severe pain is followed by swelling and a little loss of muscular strength.

Grade III (severe) strains cause the muscle to completely rupture. This signifies that either the tendon has split from the muscle belly or the muscle belly has been ripped in two. This form of strain is distinguished by severe swelling and discomfort, as well as full loss of function.
