Respiration and activity are closely related in the sense that respiration is the process by which our bodies generate energy to fuel physical activity.

During respiration, our bodies break down glucose and other molecules using oxygen to produce ATP, which is the primary energy currency of the body. This ATP is then used by the muscles to perform physical activity such as walking, running, lifting weights, or any other form of movement.

The rate of respiration increases as the body's demand for energy increases during physical activity. This increased respiration rate helps to supply more oxygen to the muscles, which allows them to continue functioning and producing ATP to support the activity.

The primate that has a Y-5 molar, is large and hangs from trees, has a sacrum but no tail is Gorilla.

Gorilla is a genus of ground-dwelling herbivorous apes that inhabit the forests of central Africa. Gorillas are the largest primates and are divided into two species: the eastern gorilla and the western gorilla. Gorillas, like humans, have opposable thumbs, but they are considerably larger and stronger than humans. They can easily crush a human skull with their bare hands if they wish.

The following are some of the distinguishing characteristics of gorillas:

They have broad chests and shoulders, with males weighing up to 400 pounds.

They are tailless primates that walk on their knuckles, which is known as knuckle-walking.

Their ears are small, and their nostrils are broad and flat, similar to humans.

Their skin and hair are black, and males have a silvery-white patch on their back after they reach maturity.

Their molars, as the question implies, are Y-5, which means they have five cusps that form a Y-shape when viewed from above.

They are primarily herbivores and feed on leaves, stems, and other plant material, although they have been known to eat ants and termites when food is scarce.

The arcuate nucleus of the hypothalamus contains two important types of neurons involved in the regulation of energy balance and food intake: the POMC (pro-opiomelanocortin) neurons and the NPY/AgRP (neuropeptide Y/agouti-related peptide) neurons.

In response to an increase in blood leptin levels, the POMC neurons in the arcuate nucleus are activated. Leptin is a hormone that is produced by adipose (fat) tissue and acts on the hypothalamus to regulate food intake and energy balance.

When leptin levels increase, the POMC neurons in the arcuate nucleus are stimulated, leading to the release of α-MSH (alpha-melanocyte stimulating hormone) and other anorexigenic (appetite-reducing) peptides that decrease food intake and increase energy expenditure.

On the other hand, the NPY/AgRP neurons in the arcuate nucleus are inhibited by leptin. These neurons produce neuropeptide Y (NPY) and agouti-related peptide (AgRP), which are orexigenic (appetite-stimulating) peptides that increase food intake and decrease energy expenditure.

When leptin levels increase, the activity of these neurons is reduced, leading to a decrease in NPY and AgRP release.

Overall, the activity of POMC and NPY/AgRP neurons in the arcuate nucleus of the hypothalamus is regulated by leptin levels, and this plays an important role in the regulation of food intake and energy balance.

Answer & Explanation:

The parathyroid glands are located in the neck and are responsible for producing the hormone called parathyroid hormone (PTH). PTH plays a crucial role in maintaining the balance of calcium and phosphorus in the blood. It does this by regulating the activity of cells in the bones and kidneys, which control calcium and phosphorus levels.

When the calcium levels in the blood are too low, the parathyroid glands secrete PTH, which stimulates the release of calcium from bones and increases the reabsorption of calcium by the kidneys. PTH also decreases the reabsorption of phosphorus by the kidneys, which helps to maintain a proper balance between calcium and phosphorus.

On the other hand, when the calcium levels in the blood are too high, the parathyroid glands decrease PTH secretion, which reduces the release of calcium from bones and decreases the reabsorption of calcium by the kidneys. This helps to prevent the calcium levels in the blood from getting too high.

The process used to release and isolate DNA from cells is called homogenization. Homogenization is a mechanical process that breaks down cells and tissues into smaller particles, allowing the DNA to be released into solution.

This process involves the use of physical force, such as grinding, blending, or sonicating the cells in a buffer solution to disrupt their structure and release their contents.

The resulting solution contains a mixture of cellular components, including DNA, RNA, proteins, and lipids, that can then be separated and purified using various biochemical techniques. Homogenization can be performed using different types of equipment, such as a homogenizer, blender, or ultrasonic probe, depending on the nature and size of the sample being processed.

Ultimately, homogenization leads to the even dispersion of particles in the solution, making it easier to isolate and manipulate specific components, such as DNA, for downstream analysis.

Answer:

permeability

Explanation:

dictionary definition: the state/quality of a material or membrane that causes it to allow liquids or gases to pass through it

in biology we use this term to describe the cell membrane, it is "semi-permeable" because it allows certain gasses and molecules to pass through

The water can easily move through a substance and it is called permeability. Hence, option B is correct.

The ability of molecules to pass through a biological membrane or barrier is known as biological permeability. Because cell membranes are selectively impermeable, substances cannot pass through the barrier without consideration. Some of the characteristics that affect permeability include polarity, hydrophobicity, charge, size, and shape.

The metabolic activities, survival, and potential use of the cell in both biotechnological applications and physiological systems are all greatly impacted by the cell membrane permeability, which controls the rate of solute transport into and out of the cell.

The water can easily move through a substance when the substance is permeable. Hence, option B is correct.

Explanation:

In sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.

Hybridization is a mixing of atomic orbitals which are of different shapes and have nearly same energy with give rise to same number of hybrid orbitals of same shape, equal energy and orientation so that there is minimum repulsion between these hybridize orbitals.

This is useful to explain the covalent bonds in organic molecules.

There are 3 types of hybridization which are based on the mixing of the orbitals

1. \(SP^{3}\) hybridization- In this type of hybridization one s orbital and 3p orbital which are of same shell of atom mix together to form new orbital.

2. \(SP^{2}\) hybridization - In this type of hybridization one s orbital and 2p orbitals mix together to form equivalent orbitals.

3. \(SP\) hybridization - When 1 s and 1 p orbital goes in the process  and mix together to form new orbital. The molecules who possess sp hybridization have linear shift with an angle of 180 degree.

Thus, in sp²-hybridized orbitals only one p-orbitals remain to form multiple bonds.
