Steatosis, also known as fatty liver disease, is a common condition brought on by an excessive accumulation of fat in the liver. There is a tiny quantity of fat in a healthy liver.

All three cusps are pulled downward when the chordae tendineae contract, opening the tricuspid valve and letting blood enter the right ventricle. Blood will immediately backflow into the atria if the chordae tendineae are damaged.
Blood will therefore continue to return to the atria, reducing blood flow into the pulmonary artery.

The condition known as hypophosphatemic rickets is X-linked dominant. The remaining choices—color blindness, hemophilia, and testicular feminization, or TFM syndrome—are all X-linked recessive characteristics.

Chloride and potassium ions enter and exit the inhibitory synapse, respectively, when neurotransmitters reach the postsynaptic membrane. An action potential is prevented from passing through the postsynaptic neuron when its interior becomes more negative. Inhibitory postsynaptic potential is the term used to describe this elevated negativity.

The Latin words anima or animalis, which translate to “having breath,” “having soul,” or “living being,” are the origin of the English word animal. Option B is incorrect because anemia is a condition in which your body does not produce enough healthy red blood cells to deliver enough oxygen to its tissues. Option A is incorrect as well.

The area between two Z-lines is known as the sarcomere, and it is the basic unit of contraction. Each sarcomere is made up of two halves of the I-band (thin filaments) and a central A-band (thick filaments). At the Z-line, the I-bands of two nearby sarcomeres converge.

A synapse occurs when the axon of one neuron and the dendrite or cyton of another neuron are very close to one another, with only a 200 Å gap between them. When a neurotransmitter is released from the presynaptic membrane, it diffuses across the synaptic cleft to the post-synaptic membrane, transferring a nerve impulse across the synapse. This causes the impulse to travel from the dendrite along the post-synapsic neuron’s length.

Darwin proposed that natural selection helps populations of individual species become more suited to their environments, so this is the right choice.

This choice is accurate as lysosomes, which are packed with potent hydrolytic enzymes, are essential for defensive activities. By releasing the digesting enzyme across the antigen, they enable its digestion and eliminate it.

55% of the volume of blood is made up of plasma. 90% water, salts, lipids, and hormones make up this substance, which is particularly abundant in proteins, including albumin, its primary protein, immunoglobulins, clotting factors, and fibrinogen.

Adult echinoderms are distinguished by the presence of a water circulatory system. There is no tracheal or canal system, no real heart, and no blood.

The energy needed to initiate a reaction is known as the activation energy. Proteins called enzymes attach to molecules, or substrates, to change them and reduce the energy needed to cause a reaction.

Both plant and animal cells have mitochondria, cytoplasm, and a nucleus. On the other hand, animal cells lack the chloroplast, an organelle that is present in plant cells.

Centrifugation is a technique that involves rapidly spinning molecules with varying densities around an axis in solution. Option A is thus the right one.

Sulfur bacteria are gamma-proteo bacteria that participate in the cycle of sulfur and nitrogen.

The process that activates an enzyme’s catalytic site is the formation of the enzyme substrate complex.

The amount of pixels is known as the resolution.

The resolution of the naked eye is 576 Megapixels, 500 times that of a compound microscope.The capacity of the unaided eye to see and detect minute details or to discern between two closely spaced objects is known as resolution. The quantity of photoreceptor cells in the retina and the optics of the eye are two of the variables that restrict the resolution of the human eye.

Option A is accurate since the relay neuron is not involved in the stretch reflex because it involves a direct connection between sensory and motor neurons. An illustration of the stretch reflex is the knee jerk.

B lymphocytes get their name because they were initially identified in the Bursa of Fabricius, a structure present in birds.

Bacteria use a process called transformation to create and integrate foreign DNA from their surroundings.

Because it involves the breakdown of alveolar elastic tissue, which in turn causes the breakdown of alveolar walls and the formation of large pockets within the lungs, emphysema is the right answer.

The term “active site” describes the precise area of an enzyme where a substrate binds and catalysis or a chemical reaction takes place. When a protein undergoes an enzyme reaction, its structural component affects whether the protein is functional. The active site may choose competitive inhibitors because of their structural similarities. Competitive inhibitors vie for binding to the active site by having structures similar to those of the enzyme’s substrate. By taking up residence in the active site, they obstruct the enzyme-substrate interaction, preventing the substrate from binding and reducing the enzyme’s catalytic activity.

In short, the axon carries nerve impulses away from the cell body after they pass through the dendron on their way to the cell body.

It is the process of turning ADP into ATP by using light energy.

Using the damaging oxidation process, dry heat aids in the organisms’ death. This aids in the destruction of big, polluting biomolecules like proteins. The organism dies as a result of the destruction of its vital cell components. To eradicate the most challenging of the resistant spores, the temperature is kept constant for nearly an hour.
