The height of the Big Bear Mountain is 1719 meter.

In Snohomish County, Washington, Big Bear Mountain, a 5,641-foot summit, is situated on the western flank of the North Cascades. Between Liberty Mountain to its south and Three Fingers to its north, it is situated in the middle. The Mount Baker-Snoqualmie National Forest manages the territory where Big Bear Mountain is located in the Boulder River Wilderness.

Western North America's marine west coast climate zone is home to Big Bear Mountain.

The majority of weather fronts move northeastward toward the Cascade Mountains from their Pacific Ocean of origin. As fronts approach the North Cascades, the Cascade Range's peaks push them upward, causing them to release their moisture as rain or snowfall onto the Cascades.

.The correct answer is option C. Labetalol and Carvedilol are both beta blockers that also show alpha receptor-blocking activity at higher doses.

Labetalol is a combined beta-blocker/alpha-blocker drug, which implies that even at low dosages, it may block both beta and alpha receptors.

Carvedilol is a non-selective beta blocker, which means that at lower dosages, it solely inhibits beta receptors, but at larger concentrations, it can also inhibit alpha receptors. Both drugs are used to treat angina, congestive heart failure, and hypertension.

The vagus nerve stimulates increased peristalsis and secretions in the digestive tract.

The correct option is b. vagus nerve.

The vagus nerve is a parasympathetic nervous system nerve that stimulates enhanced peristalsis and secretions in the digestive tract. When the vagus nerve is stimulated, it produces acetylcholine, which stimulates the release of digestive enzymes and enhances peristalsis, which aids in the movement of food through the digestive system.

While the sympathetic nervous system is in charge of the body's "fight or flight" reaction, it suppresses digestive processes such as peristalsis and secretions.

The parasympathetic nervous system is connected with increased saliva production, although this alone is insufficient to activate peristalsis and secretions throughout the digestive tract.

Due to a lack of stimulation, the absence of food in the system may result in decreased peristalsis and secretions.

Compared to aerobic respiration, glycolysis produces a much smaller amount of ATP. Specifically, glycolysis only produces a net gain of 2 ATP molecules per glucose molecule metabolized.

Aerobic respiration produces up to 38 ATP molecules per glucose molecule through the combined actions of glycolysis, the Krebs cycle, and the electron transport chain. This difference is because aerobic respiration utilizes oxygen to extract energy from glucose more efficiently. At the same time, glycolysis only uses a portion of the glucose molecule and does not require oxygen.

Glycolysis is the first stage of cellular aerobic respiration and is a metabolic process that occurs in the cytoplasm of cells. During glycolysis, a glucose molecule is broken down into two pyruvate molecules, releasing a small amount of energy used to produce a net gain of 2 ATP molecules and 2 NADH molecules.

While glycolysis is a relatively quick and inefficient process, it is essential for producing energy in cells that do not have access to oxygen, such as during intense exercise or in anaerobic microorganisms.

Organisms that are best suited for their environments will prevail in survival and reproduction. Therefore, option (D) is correct.

Natural selection is the process by which organisms that are better adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to their offspring. Over time, this can lead to the evolution of new species as the frequency of these traits increases in a population.

A substance that activates an enzyme is known as activators. An activator is a molecule that binds to the enzyme and causes it to change conformation, increasing the enzyme's catalytic activity.

Activators can be allosteric or covalent, which means they can bind to a site on the enzyme other than the active site or directly to the active site.

The molecule ATP is an example of an allosteric activator because it binds to the allosteric site of the enzyme phosphofructokinase during glycolysis and increases the enzyme's activity. The enzyme kinase is an example of a covalent activator because it adds a phosphate group to another enzyme, causing a conformational change that activates the enzyme.

Activators regulate enzyme activity in cells and are essential for many biological processes such as metabolism, signal transduction, and gene expression.

In some cases, the substrate may act as a regulatory molecule, influencing enzyme activity, but this is not the same as an activator. Some substrates, for example, may bind to the enzyme's active site and inhibit its activity, whereas others may compete for the active site and reduce the enzyme's efficiency. However, because they do not directly increase the enzyme's activity, these effects are not considered activation.

Natural selection offers a explanation for how the genetic characteristics of a species may change through time. This might lead to speciation, or the emergence of new, distinct species.

The species sometimes exists in two (or more) populations, and thus inhibits interbreeding between them. When maintained apart for a long enough time and exposed to a wide enough array of environmental conditions, each population takes its own distinct evolutionary path. New species are produced by speciation, which happens when an ancestor population splits into two or more genetically distinct descendant populations. The process of speciation involves the separation of groups from the original population and the emergence of genetic differences between the two groups. A population is a group of people who are all related.

Cytokinesis: It is the final step of cell division. During this phase in which the two daughter cells become physically separated.

Telophase: Telophase is the fifth phase of mitosis. It is the process that generally separates genetic material carried in the nucleus of a parent cell into two identical daughter cells.

Correct answer is B. Biologists hypothesized that the first land plants had a low, sprawling growth habit because the ancestors of land plants, green algae, lacked the structural support to stand erect in air.

A major extinction occurred after around 35 million years, when ice sheets momentarily covered a large portion of the world. Nobody knew why carbon dioxide levels likely dropped significantly right before the ice came.

The liverworts and mosses, according to Tim Lenton of the University of Exeter in the UK and colleagues, are to blame.
