Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
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.

Explanation:
differentiate between arteries and veins what is the importance of capillaries in the circulatory system.
Answer:
Arteries-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.
Veins-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.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[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.

FOR THE SECOND TIME-----Ughhh can someone answer this dang biology question I cant!!!!! I will mark you brainliest!!Referring to the graph, what phases together would account for approximately 25% of the time spent from a cell in the cell cycle?
A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase
Answer:
D. G2 phase and M phase
Explanation:
If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.
Organ systems maintain which of the following at
just the right
levels to support life processes?
a.) pH
b.) Carcinogens
C.) Temperature and pH
d.) Carcinogens and pH
Answer:
C.) Temperature and pH
Explanation:
Organ systems maintain the right temperature and pH levels to support life processes.
This is known as internal regulation or homeostasis.
Processes that support life requires some amount of fairly constant conditions for optimum level of metabolism to be attained. When the conditions are poor or in excess, reactions can greatly suffer. The ability of complex organism to maintain the right levels to support life processes is called homeostasis. pH and temperature are very important to all living organisms.Answer:

Some viruses attack cells by attaching to their outer covering, entering, and taking over their genetic "machinery". Viruses are able to invade cells after first attaching to their

B. Viral proteins
C. Genetic Memory
D. Cell membrane
E. Other
Answer:
I think cell membrane is answer
Viruses are able to invade cells after first attaching to their Cell membrane.
What are viruses?A virus is an infectious microorganism made up of a protein-coated segment of nucleic acid (either DNA or RNA). A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to make copies of itself.
A virus frequently causes harm to the host organism by killing the host cell in the process. AIDS, COVID-19, measles, and smallpox are well-known examples of viruses that cause human disease.
Viruses can infect people. But in reality, viruses infect a wide variety of organisms. For example, there are viruses that infect fungi and viruses that infect bacteria.
Therefore, Viruses are able to invade cells after first attaching to their Cell membrane.

explain the difference between an
autotroph and an heterotroph.
Answer:
The answer will be listed below.
Explanation:
Autotroph and heterotroph are two different terms. Autotrophs are producers, such as plants and other organisms that can produce their own food. Heterotrophs are consumers who consumes producers or other consumers to get their food. Examples include animals, people, and those who consume other things for energy.

In the boreal forest the ground thaws more and does not have a permafrost layer. This allows trees to take root. Compose an argument for categorizing mountains and polar regions as terrestrial biomes. Mountains and polar regions have these characteristics and provide land on which certain plants and animals can live.

During cellular respiration what is the direct source of the energu used in the cells of consumers?
Answer:
Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids, and amino acids.
Explanation:
Heterotrophs are consumers; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.) made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.
Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration: C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

Describe three environmental considitons that increase the rate of transpiration in plants, explaining how they operate:
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises.
Which statements describe what happens when enzymes are added to a chemical reaction?
Select all that apply.
- The chemical reaction is sped up.
- The chemical reaction is stopped.
- The activation energy is lowered.
- The enzymes are used up.
Answer:
The chemical reaction is sped up.
The activation energy is lowered.
Explanation:
When enzymes are added to a chemical reaction, they lower the activation energy needed in the reaction.
In return, that also speeds up the chemical reaction, since less energy is needed to start it.
Enzymes do not stop chemical reactions, and enzymes can also be reused, so they are not used up.
So, the first and third statements are correct.
