If a humans have more than 46 chromosomes, they will experience trisomies.

Chromosomes are fine thread-shaped structures that contain coiled DNA chains and are located in the cell nucleus. Chromosomes function as carriers of traits that can be passed on to their offspring. In humans, the number of chromosomes in a diploid cell is 46 or 23 pairs of chromosomes.

The chromosomes consist of 44 fruit chromosomes consisting of 22 pairs of body chromosomes and a pair of sex chromosomes. When someone has more than 46 chromosomes, they will experience a disorder called trisomy. Trisomy is a chromosomal disorder in which the cells in the body have three chromosomes. The cause of this excess chromosome is associated with pregnancy that occurs in women with an older age. Women who are pregnant at an old age have hormones that can affect cell division during embryonic development so as to produce extra chromosomes..

Direct gene activation is a mechanism by which hormones and other signaling molecules can directly bind to receptors on the DNA and activate or repress the transcription of specific genes

This type of gene regulation does not involve a second-messenger system. A second-messenger system is a cascade of reactions that amplifies and amplifies the signal generated by a hormone or other signaling molecule. This system is typically triggered by a hormone or other signaling molecule binding to a receptor on the cell membrane. This binding causes a conformational change in the receptor, which in turn activates an intracellular signaling cascade that ultimately leads to changes in gene expression or other cellular responses. Second messengers are small molecules like cAMP, cGMP, IP3, DAG, and Calcium that are produced in response to the binding of a hormone or other signaling molecule to the receptor.

Examples of second-messenger systems include the cyclic AMP (cAMP) system and the phosphoinositide system. These systems are used by hormones such as adrenaline, glucagon, and thyroid hormones to regulate gene expression and other cellular responses.

The high speed signals that pass along the axons of nerve cells is the function of A. Motor neuron; B. Sensory neuron; C. Relay neuron.

An electrical impulse in a neuron moves from the dendritic end to the axonal end. Chemicals released from one neuron's axonal end travel across the synapse and cause an electrical impulse of a similar nature to be produced in the dendrite of another neuron. A neuron transmits electrical impulses to muscle and gland cells in addition to other neurons.

A nerve impulse is a form of intercellular communication used by neurons. A nerve impulse, also known as an action potential, is primarily produced by electrical signals travelling along dendrites. Ions entering and exiting the cell cause the action potential.

From the dendritic end to the axonal end, a nerve impulse moves. A comparable electrical impulse is produced in a dendrite of another neuron when chemicals released from one neuron's axonal end cross the synapse.

Explanation:

Groundwater can be contimated by landfills and septic tanks

The two sides of a DNA strand, also known as the "backbone," are composed of alternating sugar and phosphate molecules. The sugar in one strand is called deoxyribose and the other strand is composed of a base, which can be adenine, thymine, guanine, or cytosine. These bases form the "rungs" of the DNA ladder and are held together by hydrogen bonds, which connect the two strands of DNA. The sequence of these bases on one strand determines the complementary sequence of bases on the other strand, which is what allows for DNA replication and the transmission of genetic information.

Answer: These types of changes/adaptations occur in order for the peppered moths to camouflage which gives them a higher chance of surviving and producing offspring.

Explanation: When the environment changed, due to pollution, the color of the moth population shifted because light-colored moths became easier to see so they were eaten more often. The darker moths were better camouflaged and more likely to survive and produce offspring. Organisms that survive have a better chance of reproducing so the population continues to grow.

Competitive inhibitors compete for the binding site in protein with the actual ligand, whereas non-competitive inhibitors do not.

A competitive inhibitor competes with the substrate for binding at the enzyme's active site. A noncompetitive inhibitor binds at a site other than the active site.

Competitive inhibition occurs when molecules that are very similar to the substrate molecules bind to the active site and prevent the actual substrate from binding. Penicillin, for example, is a competitive inhibitor that inhibits the active site of an enzyme used by many bacteria to build their cell... In repression.

Noncompetitive inhibition, a type of allosteric regulation, is a type of enzyme inhibition in which an inhibitor binds to an allosteric site, resulting in decreased enzyme efficacy. An allosteric site is simply one that differs from the active site—the location where the substrate binds.

Explanation:

Mutation effects can be beneficial, harmful or neutral (i.e, having no effect on the organism), depending on their context or location. Most non-neutral mutations are deleterious(harmful often in a subtle or unexpected way).

In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.

A cell's surface area grows as the square of its radius as the radius rises, yet its volume grows as the cube of its radius (much more rapidly). Thus, a cell's surface area to volume ratio drops as it grows in size.

A limited amount of cytoplasm can be under the control of each nucleus. This is one of the restrictions on certain biological cells' sizes. By possessing many nuclei, certain cells are able to get beyond this particular restriction. These unique cell types have multiple nuclei.
