Answer:

The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).

Explanation:

Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.

The steps in which this occurs can be summarized as follows:

According to this, the DNA determines the amino acids sequence that will be in a specific protein molecule.

Answer:

These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are msotly the same, both structurally and chemically; and finally, that energy flow occurs within.

Answer:The answer is carbohydrates and glycosylation

Answer:

(D) As a fat.

Explanation:

Lipids and fat are related to each other. Excess lipids are always going to end up as just your fat in the body sitting there unless you do some physical activity to burn that fat off by exercise.

* It cannot be sugar as it relates to carbohydrates. This gives immediate-bursts of energy.

* It cannot be enzyme as it create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.

* It cannot be protein as it relates to amino acid. This is for growth and development of the body.

Plasma osmolarity, or the concentration of solutes in blood, is the primary factor influencing antidiuretic hormone release.

Osmoreceptor neurons, which sense osmolarity in the hypothalamus, then trigger the release of antidiuretic hormone from the neurons that sense osmolarity. Osmoreceptors do not activate and antidiuretic hormone secretion is reduced when plasma osmolarity falls below a certain threshold. Ever-vigilant osmoreceptors perceive an increase in osmolarity over the threshold as a stimulus to activate the neurons that release antidiuretic hormone. The concentrations of antidiuretic hormone climb sharply and linearly with rising plasma osmolarity, as seen in the figure below.

Antidiuretic hormone release and thirst have an intriguing similarity. Although most likely not the identical ones, both occurrences seem to be triggered by hypothalamic osmoreceptors.

Answer:

Enzymes regulate metabolic processes through a variety of feedback mechanisms including inhibition.

Explanation:

Eukaryotic metabolic regulation refers to the mechanisms by which metabolic anabolic and catabolic pathways are modulated in eukaryotic organisms. Anabolic enzymes are involved in the biosynthesis of molecules, while catabolic enzymes are involved in degradative pathways. Thus, enzymes regulate metabolic pathways by catalyzing chemical reactions at their corresponding rates of reaction. Moreover, feedback inhibition refers to those mechanisms occurring when one enzyme is inhibited by the end product of the metabolic pathway, enabling cells to regulate these products.

D.) It releases energy by breaking down glucose

Explanation:

In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose...in cellular respiration, oxygen is used to break down glucose releasing chemical energy and heat in the process. Carbon dioxide and water are products of this reaction.

The primary function of photosynthesis is to convert solar energy into chemical energy and then store the chemical energy for future use. For the most part, the planets living systems are powered by this process. Photosynthesis happens in regions of a cell called chloroplast.

Natural selection is one of the evolutive forces. It can select beneficial alleles, which are the product of mutations, and fixate them in the population. Option A. Natural selection.

Natural selection is one of the evolutive forces. It acts by selecting beneficial alleles and increasing their frequency in the population.

It results from the interaction between phenotype and environment, which determines gene destiny in space and time.

Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.      

Aptitude can be defined as the contribution of each genotype to the next generation. Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. 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 habitats.

The selective agent is the environmental trait that determines the differential survival of the phenotypic classes. The environment influences the probability that each genotype passes its gametes to the next generation.

Individuals exposed to new selective pressures need to adapt to survive. Under these environmental conditions, individuals suffer mutations that lead them to avoid them. Since these mutations are beneficial, they are selected by Natural Selection, fixated in the genotype, and transmitted to the following generations.

Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.

In the proposed situation,

1) ants were exposed to insecticides.

2) probably many of them dies, but some of them mutated and managed to survive

3) since this mutation was benefitial, it was selected by natural selection.

4) ants carrying this mutation got to reproduce and the mutation spread in the population.

The correct option is then A. Natural selection.
