Which elements are present in all organic compounds

Natural selection benefits individuals with better fitness, increasing their frequency in populations. In the exposed example, white individuals can camouflage better from predators and get to survive and reproduce.

------------------------------------------

Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population.

Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.

Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.

In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or the habitat.

In the exposed example, color differences between the substrate and the crabs' bodies make them more vulnerable to the attack of predators. If this is the case, predators are acting as selective pressure or modeling environmental factor.

Red and blue crabs probable are easily seen against a white sand substrate. So the crabs' population exhibiting these colors suffer from high predation pressure.

Individuals expressing white color can camouflage better and are not seen by predators. Hence, they get to survive more in comparison with colored individuals. So crabs' response to the selective pressure is survival of white or clear individuals.

Natural selection benefits white individuals, who manage to survive and reproduce, expressing a higher fitness. The white color trait begins to spread into the whole population, and finally, it shifts towards white.

How are ants so strong?

Rashid [163]

Hello!

Well, impressively but, as you can clearly see,the reason that all ants can lift so much, or are very strong, is all because of their body size increases as a cube of length- while the cross sectional area of muscles increases as the square of length as seen.

By the way, as an extra fact, ants aren't only very strong, but extremely fast also! It is studied and estimated that the average ant as known, can carry between 10 and 50 times its own body weight! and run at approximately 300 meters an hour, a rate of nearly 800 times its body length a minute!

Very impressive right?

I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)

Why is it important that ice floats and does not sink in aquatic environments such as lakes?

VikaD [51]

It's important because the aquatic animals can survive through the winter

When an organism such as a yeast lives by fermentation, it converts the pyruvate from glycolysis into a different compound, such

Dahasolnce [82]

Answer:

The conversion is needed to regenerate the molecules needed for glycolysis

Explanation:

Fermentation is a metabolic process by which microorganisms generate ATP by the anaerobic (without oxygen) degradation of organic nutrients. Fermentation allows to microorganisms convert carbohydrates into alcohol or acid. During glycolysis, two NAD+ molecules are reduced and glucose molecules are split into two pyruvate molecules, thereby producing two NADH molecules and two ATP molecules. During fermentation, pyruvate molecules are metabolized to different compounds because the energy stored in the pyruvate molecules is unavailable to the cell. In fermentation, NADH from glycolysis is oxidized back to NAD+ by being used to reduce pyruvate or a pyruvate derivative.
