Answers

Answer:

The correct answer is - 2) density-independent limiting factor.

Explanation:

Density-independent limiting factors are the factors that cause a change in the size of the population without getting influenced by the density of the population.

Density-independent limiting factors include biotic or abiotic factors with catastrophic conditions such as natural disasters such as floods, earthquakes, drought, fires, and many more.

Drought affects the size of the population by increasing competition in the ecosystem for resources.

Answers

Answer:

The slope shows efficiency of the engine.

Explanation:

The slope indicates that the car travels a certain distance by using a specific amount of fuels. This slope shows efficiency of the engine of that car by using fuel to cover a specific distance. If the car travels more distance and used little amount of fuel so it means that the car engine has high efficiency whereas if the car used more fuel and covers little distance so we can say that it has low efficiency.

Some. produces variable traits depending on environmental conditions

Answers

Answer:

Some genes produces variable traits depending on environmental conditions

Explanation:

The interaction between some genes and environments confers on individuals different degrees of susceptibility in the appearance of a certain characteristic or in the expression of some variable traits. The trait appears in individuals who have reached a certain threshold, thus the variability in phenotypic expression could be related to the greater or lesser number of predisposing genes in each individual. The differential expression of genes depending on the environment is called the reaction norm, and it refers to genes that can be expressed in a different way in different individuals, depending on the environment in which those individuals develop. The norm of reaction is the set of pathways that a genotype can follow, in all favorable and unfavorable environments, until giving rise to the various possible phenotypes.

Which statement is the best decription of how blood circulates through the body?


A. The circulatory system pushes blood upward throughout the body
by using gravity


B. The heart contracts and relaxes causing a force to push the blood
throughout the body.


C. The respiratory system pulls the blood inward when inhaling and
pushes it outward when exhailing.


D. The blood circulates throughout the body by gravity only.

Answers

Oh okie so cute ☺️ cute ☺️ I like lol

The blood circulates throughout the body because of the contraction and relaxation of the heart which pushes the blood throughout the body.  So, the correct option is B.

What is the circulatory system?

The circulatory system is a specialized system for the circulation of blood throughout the body. This blood is rich in nutrients obtained from the digestive system after digestion and oxygen obtained from the respiratory system after breathing.

The circulatory system is like an industrial pipeline system in which a pump or motor, pipes and the component flow through the pipes.

The blood vessels represent the pipes. There are two types of blood vessels, the arteries and the veins which carry oxygenated and deoxygenated blood respectively.

The blood is the component flowing through the blood vessels. The blood is a liquid tissue, in which the liquid component is called the plasma and the cellular component is represented by three types of cells. These are the red blood cells, white blood cells and platelets. The nutrients flow freely in the blood plasma and oxygen is carried by the Red blood cells.

The heart is the pump of this system, it contracts to push blood through the blood vessels and relaxes to allow blood into its chambers. The human heart has four chambers.

Therefore, the correct option is B.
