Answer:

1.Involved in carrying pure, oxygenated blood and nutrient-rich blood.

2.Consists of three distinct layers, which are rigid, thicker and highly muscular.

3.Located deep within the body.

4.Red in colour.

5.Carry blood away from the heart to various parts of the body.

6.High pressure, as the blood flows by the pumping pressure of the heart.

7.Comparatively higher oxygen level.

8.The level of carbon dioxide is low

9.Lumina is narrow

10.Valves are absent

11.Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.

1.Involved in carrying impure, deoxygenated blood

2.Consists of three distinct layers, which are thin and collapsible.

3.Peripherally located closer to the skin.

4.Blue in colour.

5.Carry blood towards the heart from the various parts of the body.

6.Low pressure, as the blood flows by the capillary action of the veins.

7.Comparatively low oxygen level.

8.The level of carbon dioxide is high

9.In upward direction from the body tissues to the heart.

10.Lumina is wide & Valves are present.

11.Veins are less susceptible to diseases such as varicose veins.

Though tiny, the capillaries are one of the most important parts of the circulatory system because it's through them that nutrients and oxygen are delivered to the cells. In addition, waste products such as carbon dioxide are also removed by the capillaries.

Explanation:

A. Multiple organ systems working together

Explanation:

All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

Answer:

B)

Explanation:

Several groups of students were comparing the processes of mitosis and meiosis. Each group came up with a different answer for how the two processes are different.  

Mitosis- growth and repair one cell division 2 genetically identical diploid cells

Meiosis- produce gametes, two cell division, 4 genetically different haploid cells

Hope this helps :)

The group that is correct regarding mitosis and meiosis is group 2 as they said that mitosis is involved in the growth and repair of cells and undergoes cell division once, while meiosis is involved in reproduction through fusion of gametes and undergoes cell division twice. The correct option is B.

Type of cell division by which a parent cell divides into two or more daughter cells when a parent cell divides into two or more daughter cells. Cell division is typically part of a larger cell cycle.

Cell division occurs in two stages namely mitosis and meiosis. When most people say cell division, they're referring to mitosis, the method by which new body cells are formed.

Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.

The group 2 is stating the same that mitosis is the division for growth and repair and is done in only once, and meiosis is the process of gamete formation and occurs twice.

Thus, the correct option is B.

Answer:In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.

Explanation:

Answer:

Equilibrium means when the concentrations of reactants and products are in an unchanging ratio. Another way of saying this is that a system is in equilibrium when the forward and reverse reactions occur at equal rates.

Answer:

independent variable

Explanation:

Independent variable: In psychological experiment, the term "independent variable" is described as a specific variable that is being controlled, altered, or manipulated by an experimenter or researcher or investigator to see its effects on the dependent variable. Independent variable has a direct effect on the dependent variable, so any changes in the independent variable will effect the dependent variable directly.

In the question above, the amount of light in this investigation is an independent variable.

[tex]\boxed {\boxed {\sf Enzymes}}[/tex]

Explanation:

Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat.  Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.

So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.

B Because Cellulose is a polysaccharide consisting of linear chain of numerous linked D-glucose units whereas proteins are formed of number of amino acids linked together by peptide linkage.

Cellulose is a polysaccharide and a structural component of the plant cell. It is a carbohydrate made of many monomers linked together. Thus, B is the correct option.

Cellulose is an organic chemical that is insoluble in water and is a tough structure classified as carbohydrates. Cellulose is a structural component of plant cells.

It is made by monomer units linked by the beta-1,4 glycosidic bonds and is a biodegradable, tasteless organic compound with the chemical formula (C₆H₁₀O₅)ₙ.

It is the main component of the plant cell wall that provides support and shape due to its fibrous structure. It is made of linear chains of D-glucose units that makes the polysaccharide.

Therefore, option B. cellulose is a carbohydrate.

Answer:

C. Most mammals are secondary consumers. Most invertebrates are primary consumers.

Explanation:

Net production efficiency (NPE) refers to how efficient an organism at one trophic level utilizes and transfers energy to the next trophic level. Ceetain organisms called CONSUMERS obtain energy by feeding on other organisms. They use this energy for their metabolic activities and transfer the rest when eaten or fed on.

As the trophic level increases, the net production efficiency decreases. This is because organisms at the lower level use energy less than those at higher trophic levels. In this question, invertebrates are mostly PRIMARY CONSUMERS (lower trophic level) while mammals are mostly SECONDARY CONSUMERS (higher trophic level). Therefore, invertebrates use energy more efficiently (less) than mammals, making them have a HIGHER net production efficiency than mammals.

Explanation:

Answer:

You must come in contact with the infected air. It spreads slower, and more than one person is usually affected at the same time.

Explanation:

Answer:

Greenhouse gases, such as carbon dioxide, methane, nitrous oxide, and certain synthetic chemicals, trap some of the Earth's outgoing energy, thus retaining heat in the atmosphere. This heat trapping causes changes in the radiative balance of the Earth—the balance between energy received from the sun and emitted from Earth—that alter climate and weather patterns at global and regional scales.

Multiple lines of evidence confirm that human activities are the primary cause of the global warming of the past 50 years.1 Natural factors, such as variations in the sun's output, volcanic activity, the Earth's orbit, the carbon cycle, and others, also affect Earth's radiative balance. However, beginning in the late 1700s, the net global effect of human activities has been a continual increase in greenhouse gas concentrations.

This change in concentrations causes warming and is affecting various aspects of climate, including surface air and ocean temperatures, precipitation, and sea levels. Human health, agriculture, water resources, forests, wildlife, and coastal areas are all vulnerable to climate change.

Many greenhouse gases are extremely long-lived in the atmosphere, with some remaining airborne for tens to hundreds of years after being released. These long-lived greenhouse gases become globally mixed in the atmosphere and their concentrations reflect past and recent contributions from emissions sources worldwide. Others, like tropospheric ozone, have a relatively short lifetime in the atmosphere.

High air pressure usually means clear weather because stable air is sinking. The correct option would be D.

High air pressure usually causes the sky to be clear.

This is because high air pressure causes the air at the lower atmospheric level to sink down towards the earth.

This is unlike low air pressure. It brings a cloudy sky along with precipitation.
