The peripheral layer of a creature cell is a cell film. Part H is the outside layer of the cell is called cell membrane. Consequently, choice (A) is right choice.

The cell membrane, which is also known as the plasma membrane, separates the inside of a cell from the outside world. The cell membrane is made up of a lipid bilayer that is semipermeable. The flow of substances into and out of the cell is controlled by the cell membrane.

The four primary functions of the plasma membrane are isolation of the cytoplasm from the external environment, communication, control of solute exchange across the membrane, and identification. Subsequently, the organelle marked as H is choice (A) cell layer.

Cellular respiration is the process of breaking down food molecules to obtain energy. Three major steps that occur during cellular respiration are Glycolysis, the Krebs cycle, and the Electron transport chain.

The following are the three major steps that occur during cellular respiration:

1. Glycolysis
The first stage of cellular respiration is glycolysis. In glycolysis, glucose is broken down into pyruvate in the cytoplasm of the cell. This process releases a small amount of energy, which is stored in the form of ATP (adenosine triphosphate).

2. Krebs cycle
After glycolysis, the pyruvate molecules are transported to the mitochondria for the Krebs cycle. In the Krebs cycle, the pyruvate molecules are broken down into carbon dioxide, releasing more energy, which is stored in ATP.

3. Electron transport chain
The final stage of cellular respiration is the electron transport chain. In this stage, energy is transferred from the NADH and FADH₂ molecules produced in glycolysis and the Krebs cycle to create a proton gradient across the mitochondrial membrane. This gradient drives the synthesis of ATP through a process called chemiosmosis.

Overall, the process of cellular respiration involves breaking down food molecules to obtain energy in the form of ATP. Glycolysis, the Krebs cycle, and the electron transport chain are the three major steps involved in this process.

A group of snowy owls is called a "parliament." The origin of this term is uncertain, but it may refer to the owl's perceived wisdom and solemn appearance, which are qualities associated with parliamentary proceedings.

Snowy owls are a species of large, white owls that breed in the Arctic regions of North America and Eurasia. They are highly adapted to life in cold environments and have a range of physical and behavioral adaptations that help them survive in their harsh habitat. Snowy owls are also notable for their striking appearance, with bright white feathers and piercing yellow eyes. They are a popular subject of wildlife photography and have been featured in many books, films, and other media.

Owls are birds of prey, which means that they hunt and eat other animals. They are known for their excellent hunting skills, particularly their ability to hunt in low light conditions and hear the faintest sounds made by their prey.

There are more than 200 species of owls in the world, and they are found on every continent except Antarctica.

Owls have many adaptations that help them hunt and survive, including large eyes that are fixed in their sockets (which means they cannot move their eyes like humans can), an acute sense of hearing, and silent flight due to special feather adaptations.

As the oxygen molecule enters the human body through the nose, it begins its journey through the respiratory system. The oxygen travels down the trachea, which then branches into two bronchi, one for each lung. Once inside the lungs, the oxygen molecule diffuses through the alveoli, which are small air sacs responsible for exchanging gases between the air and the blood.

Next, the oxygen molecule enters the circulatory system. It binds with hemoglobin in the red blood cells and is transported to different parts of the body. The first stop is the heart, where the oxygen-rich blood is pumped to the rest of the body through arteries. The oxygen molecule travels to different organs, including the brain, heart, and muscles, to name a few.

In the brain, oxygen is used for metabolic processes that help the neurons function correctly. In the heart, the oxygen molecule is utilized to help the muscle cells contract and pump blood efficiently. In the muscles, oxygen is required for cellular respiration, which is the process that produces energy for the body.

Once the oxygen molecule is used by the cells, it becomes carbon dioxide and is released back into the bloodstream. The carbon dioxide is then transported back to the lungs, where it is exhaled out of the body. This cycle of inhaling oxygen and exhaling carbon dioxide is known as respiration and is vital for human survival.

In conclusion, the journey of an oxygen molecule through the human body is fascinating and essential for our survival. It travels through the respiratory and circulatory systems, providing oxygen to different organs and tissues. This oxygen is used to produce energy and sustain life processes. Understanding this process is crucial for maintaining good health and well-being.

When entering the skin and cannulating a vein, the usual needle position is bevel up. This is the main answer.What is the bevel of a needle?The bevel is a slanted surface of a surgical needle's point or tip.

It's often the most pointed section of a needle. This area cuts into tissue and separates it when the needle is used in an injection or blood draw. The needle must be pointed in the right direction to make contact with the vein's wall and cannulate it.

Cannulation is the process of inserting a cannula, a thin tube or sheath that goes into a vein for therapeutic or diagnostic purposes. So, the explanation is that the needle position should be bevel up when entering the skin and cannulating a vein to penetrate the skin and tissue as painlessly as possible while still allowing proper vascular access.

There is no effective cure, the Huntington's disease is caused by a single defective gene on chromosome 4 causes a breakdown of nerve cells in the brain.

Genes are segments of DNA which are located on chromosomes contain the information's for protein production, in humans 25,000 genes are present, which exist in more than one form.

The alternative forms of gene which are are expressed as a character in a species are called alleles and they are typically present as two alleles for a given trait.

Alleles gives distinct traits that can be passed on from parents to offspring known as Mendel's law of segregation.

In humans, alleles of a gene come in pairs, one on each chromosome,  If both the alleles of a particular gene are the same, the individual is called  as homozygous, If they are different the organism is described as heterozygous for that gene.

Subcutaneous tissue is primarily composed of: Adipose tissue (image attached).

Subcutaneous tissue, also known as the hypodermis or subcutis, is the deepest layer of the skin. It lies beneath the dermis and is primarily composed of adipose tissue, which is a type of connective tissue specialized for fat storage.

Adipose tissue is made up of adipocytes, which are specialized cells that store energy in the form of triglycerides. It serves several important functions, including insulation, cushioning, and energy storage. Adipose tissue also helps to regulate body temperature and provides mechanical protection to underlying structures.

In addition to adipocytes, subcutaneous tissue may also contain blood vessels, nerves, and fibrous connective tissue. The thickness and composition of subcutaneous tissue can vary between individuals and throughout different areas of the body.

Overall, subcutaneous tissue plays a crucial role in maintaining the structural integrity and functionality of the skin, as well as contributing to overall body composition and metabolic regulation.

Yes, that is correct. If the supply of coffee decreases due to bad weather conditions in coffee-exporting countries, it would cause a leftward shift of the supply curve.

This means that at any given price, the quantity supplied of coffee would be lower. As a result, the equilibrium price of coffee would rise as consumers compete for the limited supply. Additionally, the equilibrium quantity of coffee would fall as there is less coffee available in the market. This decrease in supply and increase in price and decrease in quantity is a typical response to a decrease in supply in the market.
