Answer:
Through this remaining period, until the conclusion of mitosis, the cell contains 92 chromatids. Only the G1 phase precedes the S phase and has half the amount of DNA as the rest of the cell cycle; therefore, cells in the G1 phase have the least amount of DNA.
In the cell cycle, DNA becomes half at the division phase, or M phase (mitotic phase). As a result, each daughter cell gets a copy of the genetic material of the parent cell.
How does DNA number decrease in cell division?In the S phase, DNA duplicates, and as a result, the DNA number becomes double. In the case of humans, there are a total of 23 pairs of DNA, or 46. In the S phase, the DNA number becomes double, which is 92. The chromosome number remains the same in S phase that is 46. Chromosome numbers are counted by their centromere number. The number of centromeres and chromosomes are same.
In the division phase (M phase), the cell divides and the duplicated chromosomes are separated to make daughter cells. As a result, the 92 DNA of a cell are divided into 46 DNA. Each daughter cell has 46 DNA, or 23 pairs in M phase. In mitosis each daughter cell has 46 DNA, while in meiosis each daughter cell has 23 DNA.
Hence, in M phase and especially in anaphase, the DNA becomes half.

What occurs during the latent period of these isometric contractions.
Answer:
The latent period refers to the period of time, in which no force is generated, that elapses between the generation of an action potential and the beginning of muscle contraction. The contraction phase begins at the end of the latent period and ends at the peak of muscle tension.
Explanation:
:)
During the latent period of isometric contractions, there is no visible change in muscle length. It is the time period between the initiation of a stimulus and the actual start of muscle contraction.
Here is a step-by-step explanation of what occurs during the latent period:
1. The stimulus is received by the muscle fiber, either from a motor neuron or an electrical impulse.
2. The stimulus triggers the release of calcium ions from the sarcoplasmic reticulum.
3. Calcium ions bind to troponin, causing a conformational change in the troponin-tropomyosin complex.
4. This conformational change exposes the binding sites on actin for myosin heads.
5. ATP is hydrolyzed by myosin, providing energy for the myosin heads to bind to actin.
6. Cross-bridge formation occurs, where myosin heads attach to actin filaments.
7. However, during the latent period, there is no visible shortening or movement of the muscle fiber.
8. This is because the force generated by the myosin heads is balanced by an opposing force within the muscle, preventing any visible movement.
9. The opposing force is created by the tension in the series elastic elements of the muscle, such as the tendons and connective tissues.
10. This tension allows the muscle to maintain a stable position and prepare for the upcoming contraction.
11. The latent period typically lasts for a few milliseconds, depending on the type of muscle and the intensity of the stimulus.
12. After the latent period, the muscle enters the contraction phase, where the myosin heads continue to bind and detach from actin, causing muscle shortening and generation of force.
In summary, the latent period of isometric contractions is the time between the stimulus and the start of visible muscle contraction. During this period, the muscle prepares for contraction by releasing calcium ions, allowing myosin to bind to actin. However, there is no visible movement because the force generated by the myosin heads is balanced by an opposing force within the muscle.

Which factor least influences the rate of photosynthesis?
Options :-A) Atmospheric concentration of carbon dioxide
B) Time of day
C) Number of chloroplasts
D) Concentration of nitrogen in the air
Answer :-D) Concentration of nitrogen in the air
Explanation :- Concentration of nitrogen in air is about 78% and it's insert in nature bez neither the planets nor the animals have the ability to break three bonds of N2 molecule (gas ) so any alterations in its concentration will not make any influence in photosynthesis concentration of CO2 make influence in the maximum but it also makes its effect upto some extent and that extent is called the saturation point Time of the day is effects like in morning and Evening photosynthesis is very less in comparison to the photosynthesis in afternoonRate of photosynthesis is directly proportional to number of chloroplast as more the number of chloroplast more will be the photosynthesisThe factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.
What is Photosynthesis?Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The process of photosynthesis significantly depends on the amount and color of sunlight along with the amount of carbon dioxide because they are the reactants of this reaction while the amount of sugar is delivered as a product of the reaction.
Therefore, the factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.

Use the drop-down menus to determine which system the following structures belong to. pituitary gland thyroid gland salivary glands
The following glands may be classified by using the drop-down menus:
Pituitary Gland ------ Endocrine Thyroid Gland ------- Endocrine Salivary Gland ------- Exocrine. What do you mean by Glands?A gland is an organ that produces and releases substances that perform a specific function in the body. They perform a key role in the metabolism process.
Endocrine Glands secrete hormones whereas exocrine glands secrete enzymes. The pituitary gland secretes growth hormone, LH, etc, while the thyroid gland secretes thyroxine hormone. So, both of these glands are classified under Endocrine glands. But the salivary gland produces an enzyme called salivary amylases, which leads to the formation of saliva. Hence, it is classified under the exocrine gland.
Therefore, all the above-described glands are classified on the basis of their functions.

Which term describes the two groups of plants that do not need water to reproduce?
Paleozoic plants
cotyledons
spermatophytes
embryophytes
Spermatophyte is the term that describes the two groups of plants that do not need water to reproduce.
Water is not necessary for fertilization or reproduction in spermatophytes since siphonogamy occurs where the male gametes are transported via the pollen tube. Siphonogamy is a condition in plants in which the male cells are transferred to the eggs via the development of pollen tubes. Seed plants are often siphonogamous.
Spermatophyte is a group of plants including gymnosperms and angiosperms. Gymnosperms are cone-bearing plants, while angiosperms are flower-bearing plants. They reproduce sexually through the means of seeds.
Spermatophytes initially develop pollen for fertilization. The pollen is then transferred to the ovary via pollen tubes, resulting in the production of seeds. Pollen is transferred by vectors like air, any insect, etc. Thus, they do not require water for reproduction.
