Mutations is considered by scientists to be primarily responsible for evolution. Mutations are essential to evolution. Every genetic feature in every organism was, initially, the result of a mutation. The new genetic variant (allele) spreads via reproduction, and differential reproduction is a defining aspect of evolution.

The processes that can alter the genetic makeup of a population are: genetic drift, mutation, gene flow, and natural selection. Of these, natural selection is considered by scientists to be primarily responsible for evolution.

Step 1: Natural selection is the process by which certain traits become more common or less common in a population over time. This happens when individuals with certain traits are more likely to survive and reproduce than others. For example, if there is a change in the environment, some individuals may have traits that make them more likely to survive and reproduce in that environment, while others may not.

Step 2: As individuals with certain traits reproduce, their offspring will also have those traits. Over time, these traits become more common in the population. This means that the traits that are beneficial for survival and reproduction will become more common, and those that are not beneficial will become less common.

Step 3: As the population evolves, the genetic make up of the population changes. This change is due to natural selection, which is the primary cause of evolution. Over time, the population will become better adapted to its environment, as the traits that are beneficial will become more common and the traits that are not beneficial will become less common.

Explanation:

Answer: Streams, rivers, watersheds, and stream tables to model their evolution. Watersheds are where water collects and where water flows to the oceans. However, streams and rivers are not just water. They include particles: sand, clay, soil, and more; which are suspended in the water and move with the current or sink to the bottom. Either way they pile up as sediment or erode the river bed as they move, changing the flow and shape of the rivers, streams, and watersheds over time. This can create serious consequences for safety, erosion, production of energy and recreational opportunities; all of which affect the quality of life and health of organism who depend on stream, river, and watershed environments. Knowledge of how water flows and it interactions in streams, rivers, and watershed is also important for our understanding of ecosystems to preserve, restore, and prevent their degradation.

Compartmental differences in eukaryotic cells transcription and translation are separated in space and time. Eukaryotic cells cannot combine transcription and translation simultaneously because of the compartmental differences in eukaryotic cells.

For example in eukaryotes transcription occurs in the nucleus, while translation occurs in the cytosol at a ribosome. The separation of transcription and translation in eukaryotes is significant for a few reasons. Firstly, it enables the high complexity of gene expression and regulation. By separating the processes of transcription and translation, eukaryotes can control the timing and amount of gene expression. This is due to the fact that the separation in space and time allows for the regulation of gene expression at the level of transcription, and the regulation of protein production at the level of translation.

The separation of transcription and translation in eukaryotes also allows for the production of different proteins from the same gene. This is due to the fact that eukaryotes can control the amount of mRNA produced by a gene, and they can also control the amount of protein produced from the same gene by controlling the rate and amount of translation.

Finally, the separation of transcription and translation in eukaryotes allows for the production of proteins with different functions from the same gene. This is due to the fact that eukaryotes can control the types of proteins produced from a gene by controlling the rate and amount of translation. For example, a gene can be transcribed to create a single mRNA, but the mRNA can then be translated into multiple different proteins with different functions.

If homeostasis is achieved, life goes on; if it is not, tragedy or death result. The stability obtained is actually a dynamic equilibrium, where conditions are largely uniform yet change is constant.

Any system that is in dynamic equilibrium will eventually establish a stable balance that is resistant to external pressures of change. When such a system is upset, built-in regulatory mechanisms react to the deviations to restore equilibrium; this is an example of feedback control.

The correct answer is false. Insulin speeds up glucose transport across cell membranes and promotes glycogen synthesis and slows down glycogen breakdown.

Adipokines, proinflammatory substances, and free fatty acids are released by adipose tissue, an endocrine organ that affects both glucose and lipid metabolism. These substances reduce muscle ATP synthesis and glucose metabolism, encourage the synthesis of harmful lipid metabolites, and change insulin signaling. Insulin affects adipose tissue in two ways: 1) by increasing glucose absorption and triglyceride synthesis, and 2) by reducing triglyceride hydrolysis and the release of FFA and glycerol into the bloodstream. Elevated plasma FFA levels have been demonstrated to impair muscle insulin signaling, promote hepatic gluconeogenesis, and impair glucose-stimulated insulin response. Adipose tissue insulin resistance, which is the impaired suppression of lipolysis in the presence of high insulin levels, has been linked to glucose intolerance.

The brain stem is the most life-threatening of brain regions. Damage to which of these brain regions would be the most life-threatening because it controls many of the body's functions that are essential for life.

The most life-threatening damage to the brain would be damage to the brainstem. The brainstem is responsible for controlling vital functions such as breathing, heart rate, blood pressure, consciousness, and digestion. Without a functioning brainstem, these vital functions would cease and the person would not survive.

The brainstem is located at the bottom of the brain and is made up of the midbrain, pons, and medulla. The midbrain is responsible for controlling vision, hearing, and motor functions. The pons is responsible for relaying signals between the brain and spinal cord and for controlling sleep cycles. The medulla is responsible for controlling vital functions such as heart rate, breathing, and blood pressure.

Damage to the brainstem can be caused by traumatic brain injury, stroke, tumors, infections, and degenerative diseases. Symptoms of brainstem damage can include difficulty speaking, swallowing, or breathing; loss of sensation or movement in the face and limbs; and difficulty with balance and coordination. Treatment for brainstem damage depends on the cause, but may include medications, surgery, and rehabilitation.
