Answer:
Oxygen
Explanation:
When excessive minerals(N.P.K) and nutrient are released into the body of water from leaching and other sources,(detergents,fertilizers application,sewage etc )which leads to corresponding increase in the population of algae(algae boom)the condition is called Eutrophication.
This disrupts the oxygen cycle because,the increased algae population(algae boom) makes use of available oxygen in the habitat for respiration.With continue supply of the nutrients,the population continue to rise.The competition for oxygen with other fauna leads to shortage of available oxygen,and therefore death of these fauna,and later of the algae.
The decomposing bacteria,also used the fragment pf oxygen to decompose the algae and other dead fauna,further reducing the oxygen levels of the water,with increase in water pollution.
Answer:
nitrogen because...
Explanation:
When nitrogen and phosphorus from fertilizer are carried in runoff to lakes and oceans, they can cause eutrophication, the overgrowth of algae.
What could happen if the cell cycle for the cells in your pinky finger stopped functioning properly? (Check all that apply.)
Answer:
Hello, you did not enter the answer options, but I can help you by explaining what would happen in this case.
if the cell cycle of the cells in your little finger stops working properly, two things could happen. First, if these cells were unable to start and complete the cell cycle, your finger would be unable to heal cuts and bruises that could happen to it, on the other hand, if these cells were unable to end the cell cycle, your finger would develop cancer .
Explanation:
The cell cycle allows the cells of your circus, in this case, of your little finger, to multiply and create exactly the same cells. This process is very important to not only make your finger grow, but also to be able to heal cuts and bruises, regenerating the tissues and skin of your finger.
Unfortunately, over time, or as a result of some factors, cells may have defects in the cell cycle. In short, if the cells are unable to start and complete the cell cycle, your finger will be unable to create new cells and regenerate tissues and skins if your finger is cut or injured. In addition, the cells may not be able to finish the cell cycle and multiply in an exaggerated and unregulated way, generating a cancer in the finger.

What major factors play a role in global warming? decrease in human activity and normal climate conditions natural factors and human activity natural factors and normal climate conditions decrease in human activity and natural factors
Answer:
natural factors and human activity
Explanation:
Global warming is the gradual increase in the earth's atmospheric temperature. It is a cause of concern for every country as it affects the whole planet. Global warming is caused by the production and release of Greenhouse gases into the atmosphere.
Greenhouse gases like C02, methane, nitrous oxide etc. are gases that have the ability to trap heat energy, hence, the increased accumulation of these gases in the atmosphere leads to a rise in global temperature.
The emission of greenhouse gases, which in turn induces global warming effect, is majorly contributed by natural factors and human activities. Natural occurrences like volcanic eruption etc release these gases into the atmosphere. Also, on a large part, the emission of CO2 caused by the burning of fossil fuels is the major problem. This burning of fossil fuels is carried out by humans. Coals, petroleum and other non-renewable source of energy are used daily, which creates havoc to the environment.
Therefore, the contribution of natural factors and human activities play a huge role in global warming.

Arrange the following steps for contraction in the correct sequence.
1. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
2. Thin filaments are pulled over the thick filaments.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. The impulse arrives at the synapse and travels through the transverse tubules.
5. The muscle fiber shortens and contracts.
6. Tropomyosin molecules bind to exposed active sites, linking actin and myosin
Answer:
Explanation:
Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.
1. The impulse arrives at the synapse and travels through the transverse tubules.
2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.
5. Thin filaments are pulled over the thick filaments.
6. The muscle fiber shortens and contracts.
The steps with respect to the contraction should be shown in the correct way.
The impulse should arrive at the synapse & travel via the tubules of the transverse. The impulse of muscle reached to the sarcoplasmic reticulum & calcium should be released. The calcium foods should be treated as the sarcoplasm & bounded into the tropoinn molecules that left active sites.The binding of Tropomyosin molecules into the exposing of active sites, actin connected & myosin. Thin filaments should be pulled over to the filaments that are thick.The fiber of muscle should be short and contracts.

You are in your room listening to music and, realize you are thirsty, you can feel that your soda is no longer cold, and you decide to invite a friend over. What parts of the central nervous system would be primarily involved in each of these italicized behaviors
Answer:
Internal region of the brain and the hypothalamus are related to the sensation of thirst.
Thalamus is involved with the perception that the soda is not colder.
Explanation:
The central nervous system is the body system responsible for making your body receive information and respond appropriately, promoting full bodily functioning. It is formed by the brain, spinal cord and the components that form them.
Regarding the activities shown in the question above, we can say that some components of the brain are related. For example: The innermost part of the brain and the hypothalamus are related to feeling thirsty. This is because the inner part of the brain is responsible for making the brain understand how the organism is functioning, if something is missing or if there is any discomfort that needs to be resolved. The hypothalamus, in turn, is responsible for the release of hormones that signal that your body's homeostasis is unbalanced. With the interaction of these two structures you realize that you are thirsty.
In addition, the thalamus is responsible for allowing your body to receive sensory messages. It is this structure that allows you to realize that your soda is not cold when you touch the glass, or take a sip of it.

A) Sarcoidosis
B) Pneumothorax
C) Hypersensitivity pneumonitis
D) adult respiratory distress syndrome
Answer: Option B.
Pneumothorax
Explanation:
Pneumothorax occurs when air buildup between the chest wall and the lungs thereby leading to increased pressure in the chest and it inturn decrease the amount of blood that flow back to the heart because the blood find it difficult to force it's way into the chest and the heart. This is cause by injury to the chest, lung danage, rupture air blisters and mechanical ventilation.
The symptoms include decreased or absent breath sounds on the affected side, hyperresonance, and sudden chest pain on the affected side , racing heart, shock.
When a pneumothorax is large, a needle or tube is used to remove excess air.

Hans has a low sperm count. His wife Sharon is fertile and has a child from a previous marriage. They are exploring options to improve their chance of conceiving. Which option makes sense given the situation?
Answer:
Intrauterine insemination IU
Explanation:
In this scenario the required numbers of sperm are not released in the semen of the Hans needed to fertilize Sharon ovum..Therefore,a technique is needed to directly inject an healthy sperm, into her uterus to fertilised her ovum directly,the technique is IU.
It is a process which involve the selection of healthy sperm.and injected this during ovulation in the female.With this procedure,the likelihood of fertilization and pregnancy occurring is high,as the distance,time and competition with other sperm cells is reduced.This makes the procedure reliable.
It is simple technique which involves the sperm washing to get the best concentration of sperm to use, monitoring of the ovulation and optimal timing; which targets best time of ovulation,usually day 1 or day 2 after ovulation.
it is relatively less expensive.

methane
production and transport of oil and natural
gas
nitrous oxide
burning fossil fuels
Answer:
carbon dioxide- burning of fossil fuels
fluorinated gases- industrial processes
methane- production and transport of oil and natural
gas
nitrous oxide- agricultural and industrial activities
Explanation:
Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.
Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.
Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.
Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.
Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
