Adaptation is a heritable behavioral, morphological, or physiological trait that has emerged through natural selection to preserve or improve an organism's fitness. Therefore, option (C) is correct.

The term "adaptation" refers to a behavioral, morphological, or physiological trait that is inherited and has developed as a result of natural selection to maintain or improve an organism's fitness in response to a specific set of environmental conditions. Adaptation can be thought of as a heritable trait.

One useful illustration is the capacity to conceal oneself. Camouflage is an adaptation that helps an organism blend in with its surroundings so that it is not obvious to other organisms in those same circumstances. The organism is also able to protect itself from the hostile environment thanks to its adaptations.

Answer:

All plants and animals on earth engage in a process called respiration. Respiration combines oxygen and the food created during photosynthesis to produce usable energy. One of the byproducts of respiration is CO2, this is the opposite of photosynthesis. It is not unusual for plants to stop taking in carbon dioxide to uptake small amounts of oxygen at night.

In the event that plants cease to take up CO2 all together, they will cease to convert sunlight into carbohydrates, and die. The death of autotrophs would lead to a chain reaction of the death of all higher order organisms. Mankind could survive on food stuffs on hand, but only for a very short time. It has been said that any western society, its members are just 3 meals away from revolution.

Social order would be completely lost during the initial food riots. Once the processed and packaged food supply is exhausted, it would be the law of the dying jungle. The strong and well armed would take from the weak and ill prepared. Livestock and game would be slaughtered as the next to the last food source disappeared. The shear volume of death would foul the water spreading pestilence and disease. In one or two years bands of humans would prey on other humans as they degenerate into cannibalism. There could be a few humans in protected bunkers and hideaways, but they too would eventually succumb to starvation or despair as the world died.

The fact that plants stopped converting CO2 into O2 would be of little consequence. Man would die of hunger 1000 years before oxygen was ever an issue.

Aerobic respiration is more efficient and producing ATP because oxygen is an excellent electron acceptor for the chemical reactions involved in generating ATP and the stage each molecule of ATP comes from is during oxidative phosphorylation.

This is referred to as a  chemical process in which oxygen is used to make energy from carbohydrates in the form of ATP as it is known as the energy currency of the cell.

Antioxidant

Explanation:

Most serum uric acid is freely filtered in kidney glomeruli, and approximately 90% of filtered uric acid is reabsorbed, implying that it has a considerable physiological role [2], [5]. In humans, over half the antioxidant capacity of blood plasma comes from uric acid [5], [6]. Uric acid is a strong reactive oxygen species (ROS) and peroxynitrite scavenger and antioxidant [5], [6], [7], [8]. High levels of uric acid are readily detected in the cytosol of normal human and mammalian cells, especially in the liver [9], vascular endothelial cells, and in human nasal secretions, where it serves as an antioxidant

Force acting on the plane = 87,500 N

Answer:

The evolution of species’ niches is a process that is fundamental to investigations in numerous fields of biology, including speciation, community assembly, and long-term regional and global diversification processes. It forms the nexus between ecological and evolutionary questions. Topics as diverse as ecological speciation, niche conservatism, species coexistence, and historical biogeography all rely on interpreting patterns and drivers of species’ niches through time and across landscapes. Despite this importance, a distinct research agenda concerning niche evolution as a discrete topic of inquiry has yet to emerge. Niche evolution is often considered as a sidebar or of secondary importance when addressing questions such as “how did two species diverge?” Basic questions such as “what is a niche,” “what is the biological basis of niche evolution,” “at what scale should we evaluate niche evolution,” and “how can we observe niche evolution at different timescales” have rarely been addressed directly, or not at all in some systems. However, various intellectual threads connecting these ideas are evident in a number of recent and historical publications, giving some semblance of form to a framework for interpreting and evaluating niche evolution, and outlining major areas for future research from an evolutionary perspective. There is a reverse perspective from the macroecological scale as well, with questions involving coexistence, distributions and ranges, food webs, and other organismal attributes

adipose tissue By the end of early childhood, girls have more adipose tissue than boys.

By the end of early childhood, girls have more adipose tissue than boys. Adipose tissue, also known as body fat, is an essential component of the body that provides insulation and energy reserves. It is normal for girls to have more adipose tissue than boys, as their bodies prepare for future reproductive functions. However, excessive adipose tissue in both girls and boys can lead to health problems such as obesity and related diseases.

During early childhood, girls and boys have similar amounts of body fat. However, as they approach puberty, hormonal changes in girls cause an increase in body fat, particularly in the hips, thighs, and breasts. This increase in adipose tissue is necessary for future reproductive functions such as menstruation and pregnancy.

We know that the diploid number in humans is 2n=46. This means that the haploid number is n=23.

We need to know the fraction of a man’s gametes that contains centromers inherited from the the father or the mother.

A gamete has 23 chromosomes.

Half of the centromers could be inherited by the father (1/2) and half by the mother (1/2).

Explanation:

I took the test it was correct. ( i know thats not an explanation im sorry but its correct).

When hexokinase and Mg2+ are present, ATP phosphorylates glucose. In the presence of nicotinamide adenine dinucleotide phosphate, glucose-6-phosphate dehydrogenase (G6PD) converts (NADPH).

Hexokinase phosphorylates glucose in the initial stage of glycolysis. Glucose would be able to diffuse past the plasma membrane and leave the cell if it weren't phosphorylated.

In a nutshell, the hexokinase/glucokinase enzymes phosphorylate glucose after it has been delivered into cells [6]. Glucose-6-phosphate (G6P) can be used in the process of glycolysis to create ATP and NADH, stored as glycogen, or utilized by the body.
