Answer: Catalase activity increases as the temperature goes from 0'C to around 30'C. Catalase activity decreases as temperature goes from around 30'C to 100'C.

Explanation:

Catalase is work at 0'C to around 30'C temperature and its activity is decreased from above 30'C to 100'c.

Every organism needs to survive at optimum temperature and pH, because its critical enzymes are showing activity at a particular range, above and below this range, enzymes lost their activity.

Catalase enzyme is used for the decomposition of hydrogen peroxide into water and oxygen. It is commonly found in nearly all organisms that are exposed to oxygen.

Therefore, an optimum temperature is required for an enzyme to show its activity, so catalase is work at 0'C to around 30'C.

Answer:Polypeptide Chains

Explanation:

One possible molecule that can be added to a membrane to make it easier for membrane proteins to move about is cholesterol. Cholesterol helps to maintain the fluidity of the membrane by preventing the fatty acid tails of the phospholipids from packing too tightly together. This allows membrane proteins to move laterally within the membrane, facilitating their interactions with other molecules and their proper functioning. Other molecules, such as glycolipids and glycoproteins, can also affect the fluidity and movement of membrane proteins, but cholesterol is a major contributor to these properties.

Molting occurs during the gradual metamorphosis of an insect whenever the nymph outgrows its exoskeleton.

What happens prior to molting?

The initial stage of molting is called apolysis, during which the old cuticle separates from the epidermis and particular epidermal cells and dermal glands secrete a molting fluid. During the molting process, the molting fluid fills the area between the old and new cuticles.

The process of molting involves the exoskeleton (cuticle) of the preceding life stage being shed. An insect cannot develop if it does not molt. An insect engages in species-specific stereotyped patterns of movement (molting behaviors) once a new cuticle has fully developed in order to be released from the cuticle of the preceding stage.

Plates move away from each other at divergent boundaries. Plates move towards each other at convergent boundaries.

Divergent boundaries form along spreading centers where plates are moving apart and magma pushing up from the mantle creates new crust. Consider two massive conveyor belts that are parallel but moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest. When a divergent boundary occurs beneath the oceanic lithosphere, the rising convection current below lifts the lithosphere, resulting in the formation of a mid-ocean ridge.

The lithosphere is stretched by extensional forces, resulting in a deep fissure. When the fissure opens, pressure on the super-heated mantle material below is reduced. It melts in response, and new magma flows into the fissure. After that, the magma solidifies.

Option - B : ventricles.The thick-walled inferior chambers of the heart that pump blood into the arteries are called ventricles.

The human heart has two ventricles: the right ventricle and the left ventricle. Deoxygenated blood is pumped by the right ventricle to the lungs, where it is given oxygen and given off carbon dioxide. Blood with oxygen is circulated throughout the body through the left ventricle.

The interventricular septum, a muscular wall, divides the ventricles from the heart's two upper chambers, the atria. Blood is pumped into the ventricles by the atria, which also aid in controlling blood flow through the heart. The atria have tiny, ear-like projections called auricles. They assist in controlling the flow of blood through the heart and have a slight impact on blood circulation.

Basophils increase in number when parasitic invasion occurs - True.

Basophils are a type of white blood cells that play an important role in the immune system. They are responsible for the release of histamine and other mediators of inflammation that play a crucial role in allergic reactions and defense against parasites. When there is an invasion of parasites in the body, basophils are one of the first immune cells to be activated.

During a parasitic invasion, basophils migrate to the site of the infection and release their granules, which contain histamine and other substances that help to destroy the invading parasites. Basophils also stimulate other immune cells, such as eosinophils, to attack the parasites. This coordinated response by the immune system is important in eliminating the parasitic infection.

As a result of their activation during a parasitic invasion, the number of basophils in the bloodstream typically increases. This increase in basophils is known as basophilia. Basophilia can also occur in other conditions, such as allergies or certain blood disorders, but when it is associated with a parasitic infection, it is a sign that the immune system is working to fight off the invaders.

In summary, basophils play a critical role in the immune response to parasitic infections. An increase in basophil count is a sign of their activation in response to the invasion. Therefore, the statement "Basophils increase in number when parasitic invasion occurs" is true.
