following an oil spill in the gulf of mexico, a population of fish evolves increased tolerance to oil over a period of several generations. which statement is most likely to be true? all individuals in the initial population must have had the same degree of tolerance to oil. this should be considered a case of evolution by artificial selection because the response came rapidly. this should be considered a case of natural selection because humans were not selecting for particular desirable traits. this should be considered a case of evolution by artificial selection because it came about due to human activity. all individuals in the current population must have the same degree of tolerance to oil.

In the particular case given in the question, the compound is a competitive inhibitor.

Enzymes are biocatalysts. Like other catalysts, it can lower the activation energy and drive the reaction in the desired direction. Because their activity depends on protein folding, they are usually sensitive to the temperature, pH, and salt concentration of the environment in which they work. The substrate enters the active site of the enzyme to form the enzyme-substrate complex. A reaction then takes place, converting the substrate to a product and forming an enzyme-product complex. Now the product is  released from the active site of the enzyme.

First, an increase in substrate concentration leads to an increase in the rate of enzyme-catalyzed reactions. This rate increase plateaus when the enzyme molecules become saturated with substrate. The rate of enzyme-catalyzed reactions increases with increasing concentrations of the enzyme.

The two resulting daughter cells would not be completely identical if divide first and then duplicate chromosomes.

The replication that occurs after division would generate mutations, which couldn't be repaired according to the parent cell. In this case, the genetic information would be inherited less accurately. This way of cell division would be disadvantageous for organisms and would likely be eliminated.

Normally before the cell divides completely, the chromosomes are duplicated identically and this division has several checkpoints to ensure that the process is going well. It is regulated by cyclin proteins. if it doesn't clear the checkpoint, it will not be allowed. So chromosome division is very well organized by the cell.

When the reverse happens, the chromosomal division may be collapsed incorporating mutations that are not gonna help the cells. when the cells get divided first.

Medication is to be taken as soon as possible for fevers.

The right response is B.

What advantages does having a fever have? No sickness causes a fever. It is an indication that your body is struggling to fight off a disease or infection. Fever activates the body's defenses, causing white blood cells and other "fighter" cells to be sent to battle and eradicate the infection's root cause.

Your immune system can fight infections in two ways with the aid of a fever. The body's internal temperature affects how quickly cells function, particularly those that fight disease.

When a boom thing binds to the extracellular area of a RTK, its dimerization is brought on with different adjoining RTKs. Dimerization results in a fast activation of the protein's cytoplasmic kinase domain.

Dimerization of the EGF receptor has been described as a mechanism for activation of the kinase activity and signal transduction through the EGF receptor.

Dimerization stimulates receptor PTK activity. Monomeric receptor PTKs exhibit weak basal activity (Inactive). Ligand-induced receptor dimerization increases the local concentration of the kinase domain leading to more efficient transphosphorylation of tyrosine residues in the mobile activation loop.

When aberrant cells congregate, a solid material of tissue called a tumor is created. Tumors can affect the bone, epidermis, tissue, organs, and glands. Whenever cells in the organ divide and enlarge excessively, tumors frequently form. The body typically controls how quickly cells grow and divide. New cells either take the place of older ones or perform new roles. To make way for healthy cells, damaged or extra cells die. New cells replace those that are lost as a result of aging or damage. This methodical procedure occasionally goes wrong, allowing damaged or abnormal cells to proliferate while they shouldn't. These cells have the ability to develop into tumours, which are tissue lumps. Malignant tumors could or might not exist (benign).

According to the pressure-flow hypothesis, sucrose and water flow up the stem in the phloem when roots are sources and leaves are sinks.

According to the Pressure-Flow Hypothesis, water containing food molecules passes through the phloem under pressure. The differential in water concentration between the solution in the phloem and the comparatively pure water in the neighboring xylem ducts causes the pressure.

the contents of the phloem experience a drop in osmotic pressure.

The comparatively clean water that is still in the phloem eventually escapes through osmosis or is drawn back into the neighboring xylem vessels by transpiration-pull. Thus, the phloem contents are forced up and down through the sieve elements by the pressure gradient between "source" (leaves) and "sink" (shoots and roots).
