Plankton are organisms that are too small to move faster than the currents.
Nekton are larger organisms that can move faster than the currents.
Benthos are small organisms that live on or in the seafloor.
The classification of all living organisms is based on basic, shared characteristics. Each group of organisms is then subdivided into smaller groups. These smaller groups are formed on the basis of more specific similarities within each larger group. Living organisms are classified primarily to avoid confusion, to facilitate organism study, and to learn how various organisms are related to one another.
There are several types of marine organisms. These include several bacterial genera and species, as well as protozoans, planktons, marine invertebrates, and vertebrates. There are three major groups of marine animals based on habitat and mobility: plankton, nekton, and benthos.

A. Fevers disrupt homeostasis
b. Fevers should immediately be treated with medication .
C. Fevers are a necessary part of maintaining homeostasis .
D. Fevers are rarely caused by bacterial infections .
Medication is to be taken as soon as possible for fevers.
The right response is B.
Does having a fever have any advantages?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.
Is a fever beneficial to the immune system?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. They can react to encroaching pathogens more quickly. Additionally, bacterial and viral growth is hampered by greater body temperatures.

the binding of a compound to an enzyme is observed to slow down or stop the rate of the reaction catalyzed by the enzyme. increasing the substrate concentration reduces the inhibitory effects of this compound. which of the following could account for this observation? the compound forms a covalent bond with one of the amino acid residues needed for enzyme activity is a competitive inhibitor is a negative allosteric regulator reduces disulfide bonds, causing the enzyme molecules to partially unfold
In the particular case given in the question, the compound is a competitive inhibitor.
Describes enzyme-substrate reactions.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.

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).
