make a claim about the relationship between temperture and chriping
Stridulation, the rubbing together of two bodily parts to make sound, is how crickets chirp. Numerous insects stridulate in various ways, including by rubbing their legs together, against their heads, and so forth.
What is the relationship between temperature and chirping?Male crickets make the nightly repeated chirp they use to attract females by rubbing their wings together more quickly as they warm up.
It has long been known that temperature and cricket chirping are related.
Therefore, with increase in temperature results in increase in number of crickets chirp.

The chemiosmotic gradient is an electrochemical gradient of hydrogen ions across the.
The chemiosmotic gradient is an electrochemical gradient of hydrogen ions across the mitochondrial membrane.
Hydrogen ions move back over the mitochondrial membrane and into the matrix due to a chemiosmotic gradient, where they pass via ATP synthase and produce ATP. One glucose molecule's aerobic respiration produces 38 ATP when ATP from the Krebs Cycle and glycolysis are included.
What is a Chemiosmotic Gradient?
A differential in proton concentration is produced across the inner membrane by the removal of protons from the matrix and their deposit in the intermembrane gap. The term for this is chemiosmotic gradient.
Therefore, the chemiosmotic gradient is an electrochemical gradient of hydrogen ions across the mitochondrial membrane.

Most of the metabolic activity happens within the cytoplasm of a cell.
Metabolic activity refers to the various processes conducted inside the cell in order to synthesize energy. The metabolic activities are of two types: anabolic and catabolic. Anabolic activities are the ones that form large compounds by combining the smaller ones, while catabolic ones are the opposite.
Cytoplasm is the gel-like liquid material present inside the cell. It is composed of the fluid of the cell and the cell organelles. Fluid present inside the nucleus is excluded from the cytoplasm.

Why is the level of water vapour variable in inhaled air
The level of water vapor variable in inhaled air due to the factors like difference in the temperature, and availability of water to evaporate.
Why is the level of water vapor variable in inhaled air?See the amount of water vapor present in the atmosphere is called humidity which have already studied in earlier classes well.Now we cannot expect the water vapor to be constant as it varies from environment to environment , and temperature to temperature.Actually water vapor is variable which means its amount in air at any one place in troposphere is not fixed.We inhale air present in the atmosphere , and it is absolutely not necessary to have the air which contain water vapor.So the amount of water vapor present in the atmosphere is a variable and not a constant.To know more about water vapor visit:

What is least characteristic of the pharyngeal tonsils?
The least characteristic of pharyngeal tonsils is the tonsils that are most commonly removed by tonsillectomy.
The entry of the nasal cavity into the pharynx is where the pharyngeal tonsils are located. Adenoids are the name for these tonsils, which can block breathing when they expand. The palatine tonsils are located close to the pharyngeal opening where the oral cavity enters.
The respiratory epithelium lines the pharyngeal tonsil but stratified squamous epithelium lines the lingual tonsil and is placed near other structures within the tongue (e.g., salivary glands), which helps to identify it from the palatine tonsils.
The pharyngeal tonsils are also known as adenoids and they guard against infections and cleanse out harmful particles.
Colds, throat irritation, and sore throats can still occur after tonsillectomy. However, one will not acquire tonsillitis (enlarged pharyngeal tonsils) until the tonsils regenerate, which is unlikely. Despite the fact that the tonsils are a component of the immune system, eliminating them has no effect on the body's capacity to fight infections.

When female living Dungeness crabs are ready to molt, they lose their exoskeleton to enable them to grow and produce a larger shell; this is the ideal time for mating before the new, hard shell has developed.

Vitamin b12 is essential for the proper functioning of nerve cells
The correct option is (b) nerve
Cobalamin, a naturally occurring type of vitamin B12, is present in animal diets. It can also be included into meals or supplements. Vitamin B12 is needed to build DNA and red blood cells. It also significantly affects the development and functionality of brain and nerve cells.Our food's protein and vitamin B12 combine to form a connection. Enzymes and hydrochloric acid dissolve the link of vitamin B12 in the stomach, causing it to become free vitamin. Following that, vitamin B12 collaborates with an intrinsic factor protein to support continuous absorption in the small intestine.The best approach to tell if someone is vitamin B12 deficient is not to measure vitamin B12 levels in the blood since some deficient individuals might have normal vitamin B12 levels. Homocysteine and methylmalonic acid levels in the blood are stronger indicators of true vitamin B12 activity than homocysteine. When there is a vitamin B12 deficit, these numbers rise.

What do you mean by offspring?
The young creation of living organisms, known in biology as progeny, can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
The gene drive technology, based on CRISPR incorporated in the native chromosome, is used to alter a species by eliminating certain character and introducing a good one, here gene preventing malaria. The key components are CRISPR, Cas9 and a gene of interest (gene preventing malaria). The mechanism involves cutting of the native chromosome at the required site followed by coping the drive sequence as happens in homologous repair. So, the gene causing malaria is inactivated. This character is passed to the next generations. If this is introduced in maximum individuals, after 15-16 generation we can see the gene preventing malaria present in all individuals.
