The endoplasmic reticulum (ER) is a dynamic organelle that regulates intracellular calcium stages and is answerable for many mobile features inclusive of protein and lipid synthesis.

The endoplasmic reticulum is the transport system of eukaryotic cells, but it also performs many other important functions such as protein folding. It includes two subsets: Rough endoplasmic reticulum and smooth endoplasmic reticulum.

The endoplasmic reticulum forms an interconnected network of flattened vesicles surrounded by membranes called cisterns and tubular structures in most eukaryotic cells. The ER membrane is connected to the outer nuclear membrane. Red blood cells and sperm do not contain endoplasmic reticulum. The endoplasmic reticulum performs several common functions, including folding protein molecules into vesicles called reservoirs and transporting the synthesized proteins to the Golgi apparatus in vesicles. The rough endoplasmic reticulum is also responsible for protein synthesis.

Eukaryotic initiation begins after the assembly of pre-initiation complex.

Pre-initiation complex (PIC) is an essential component of the process of transcription. It is comprised of around 100 types of proteins that together are involved for beginning the process. The complex is seen in eukaryotes as well as archaea. The major function of the complex is recruitment of RNA polymerase.

Transcription is the process which is a part of the central dogma. Here the DNA strand is used as a template to form the single-stranded RNA. The process occurs in the nucleus of the eukaryotic organisms. It is accomplished in three steps: initiation, elongation and termination.

Explanation:

Option  C is the correct answer that is savannas have relatively long dry seasons.

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.

So choice C is the correct answer.

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.

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.

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. And those proteins which stick outside of the plasma membrane will allow for one cell to interact with another cell. The cell membrane also provides some structural support.

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.

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.
