Science is the main responsible for the creation of any and all technology capable of maintaining or creating better levels of quality of life. Through these technologies, better treatments and cures for diseases are developed, better food distribution, better educational methods, better urban infrastructure, better and greater food production, new jobs, among other factors that are very important for the maintenance of life such as improvement of the elements that we already have.

It is important to note that science is responsible for the progress of a nation. Nations that adopt negative and anti-science stances are doomed to ostracism and will be weak, vulnerable and completely out of date.

Answer:

availability of resources.

Explanation:

Availability of resources is abiotic factor which is responsible for the decrease in population in 1990 because when the population reaches its carrying capacity so the organisms compete with each other and due to limited resources such as food etc the decrease occurs in population. Infection is also occurs when there is high population due to which death occurs and population of organism decreases.

Some of the matter taken in by an animal can be transferred to the next level of food chain because some of the matter has been consumed by the animal organism for natural processes.

Food chain is a term that refers to the food relationship that involves several species of a biological community. The trophic chain is based on the transfer of nutritive substances in which each species feeds on a preceding species and so on.

A peculiarity of the food chain is that not all the material that an animal species ingests is transferred to the animal that feeds on it. This is because part of this material has already been consumed as energy for all the natural processes of the body, so only a small part is transferred to the next.

Answer:

Free radical theory of aging.

Explanation:

Free radical theory of aging suggests that aging is the result of unstable oxygen molecules that cause damage to the structure of cells with age because cells accumulate free radical damage overtime and free radical is an atom with unpaired electron in it's outermost shell. It is associated with oxidative damage.

the free radical theory is only concerned with free radicals such as superoxide ( O2− ), but it also comprises of oxidative damage from other reactive oxygen species such as hydrogen peroxide (H2O2), or peroxynitrite (OONO−).

D. Formation of carbonates in the ocean.

(APEX)

Formation of carbonates in the ocean removes carbon dioxide from the atmosphere, acting as a carbon sink. Thus, the correct option is D.

Carbon is stored on the planet in the following major sinks as organic molecules in living and dead organisms found in the biosphere, as the gas carbon dioxide in the atmosphere, as organic matter such as carbonates in soil and oceans, in the lithosphere as fossil fuels and sedimentary rock deposits such as limestone, dolomite.

The removal of carbon dioxide is essential because of continued high rates of global emissions. Since industrial revolution, carbon dioxide gas emissions have been building in the atmosphere, creating a warming layer of carbon pollution which is causing climate change.

Explanation:

Test crosses are used to determine the genotype of an individual that expresses a dominant trait by crossing this individual which an homozygous recessive individual expressing the recessive trait. The pollination experiment could be a test cross.

Test crosses are experimental crosses carried out to determine the genotype of one of the involved individuals.

Test crosses include a homozygous recessive individual and another individual of an unknown genotype whose phenotype we already recognize.

The main goal is to know if the individual of the unknown genotype is a heterozygous or a homozygous dominant individual.

→ 50% of the progeny will be heterozygous and express the dominant phenotype,

→ 50% homozygous recessive expressing the recessive phenotype.

In the exposed example, we have two traits: tall and short.

We will assume a diallelic gene codes for this feature, and expresses complete dominance.

To determine if tall plants are homozygous dominant or heterozygous we will separate them and produce controlled test crosses with short plants, which are homozygous recessive.

The test cross between homozygous recessive plants and homozygous dominant plants will only produce tall plants.

Answer: the speed of the body

Explanation: kinetic energy is equal to the the half of the multiple of mass and speed so the increasing and decreasing of the speed has a greatest impact on the kinetic energy.

Add me as the brainleist please!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The kinetic energy of a body depends on its mass and velocity but velocity has the greatest impact on kinetic energy.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The SI unit of kinetic energy is the joule (J).

Radiant, thermal, acoustic, electrical, and mechanical kinetic energies are the basic categories. The capacity to perform work is kinetic energy's most significant quality. Kinetic energy can be increased by increasing mass and velocity and can be decreased by decreasing them.

Kinetic energy depends on both the mass and velocity of the body but it is most affected by velocity.

Answer:

d) introducing a competing species.

Explanation:

Competition refers to a dynamic partnership in which various species or populations in the environment concurrently seek to utilize the same available resources. Organisms in an ecosystem compete for the same limited nutrients and in the process, one ultimately got an edge over the other. because resources are limited in nature, the population of one species decreases at the expense of the survival of the other.

The correct answer is "lateral horns of the T1L2 segments of the spinal cord".

Explanation:

The missing options of this question are:

A. anterior columns of the spinal cord.

B. posterior columns of the spinal cord.

C. sympathetic trunk.

D. lateral horns of the T1L2 segments of the spinal cord.

E. paravertebral ganglia.

The correct answer is option D. "lateral horns of the T1L2 segments of the spinal cord".

The cell bodies of the sympathetic preganglionic are located in the visceral efferent column of the spinal cord, which is also known as the lateral horns of the spinal cord. Since the cell bodies belong to preganglionic nerve fibers, they are always located close to the spinal cord. On the other hand, parasympathetic ganglia are often not located within the spinal cord, and act separate from the autonomic nervous system.
