<span>The circulatory body system, otherwise known as the cardiovascular or vascular system, is composed of four major parts: the heart, arteries, and veins. The vital responsibilities of the said system is to circulate blood throughout the body, transport nutrients, and carry away waste for elimination. Circulation starts when the heart pumps out blood through the main artery aorta, into the lung capillaries for oxygenation, and throughout the body via the arteries. Besides oxygen, nutrients and metabolic products are distributed as blood circulates, waste is processed and soon after eliminated by the kidneys as blood circulates there, and un-oxygenated blood returns to the heart through the superior and inferior vena cava (veins), the whole cycle therefore carrying on.</span>

Deffense [45]

Answer:

This question is incomplete as it lacks options. The options are:

A) Nitrogen will be incorporated into nucleic acids.

B) Phosphorus will be incorporated into amino acids.

C) Potassium will be incorporated into lipids.

D) Magnesium will be incorporated into carbohydrates.

The answer is A. Nitrogen will be incorporated into nucleic acids.

Explanation:

Fertilizers serve as external source of nutrients as they contain certain elements necessary for the build up of biomolecules in living organisms. According to this question, the bag of fertilizer contains the following elemental components: nitrogen, phosphorus, potassium, magnesium and calcium.

These elemental components of the fertilizer will be incorporated by organisms and used to build biomolecules in their systems. The four biomolecules are carbohydrate, proteins, lipids and nucleic acid. NUCLEIC ACID is a complex biomolecule made up of simpler NUCLEOTIDE subunits. Each nucleotide is made up of a pentose sugar, phosphate group and NITROGENOUS BASE.

NITROGENOUS BASE is a base which principally contains NITROGEN in the core of its structure. Hence, nitrogen element is a vital component necessary for the formation of nucleic acids. Therefore, Nitrogen component of the fertilizer will be incorporated into nucleic acids of organisms in the area.

wlad13 [49]
Every organism in an ecosystem relies on other species for survival: Species diversity. An ecosystem is a b<span>iological community of interacting organisms and their physical environment. The survival of one species therefore depends on the survival of other species.</span><span>

Reduced options for mates can lead to inbreeding: Genetic diversity. Inbreeding occurs when closely related individuals breed, and this can lead to the expression of undesirable traits such as those associated with recessive genes.

Decreased diversity can lead to increased susceptibility to disease: Genetic diversity. This is related to inbreeding. The expression of recessive genes can decrease the overall fitness of a species and increase its susceptibility to disease. 

The loss of a producer could result in the loss of consumers: Species diversity. This is related to the concept of an ecosystem. Consumers rely on producers as a food source. 

When a population becomes small, diversity is lost: Genetic diversity. This is commonly known as the 'founder effect'.</span>
