Body systems in the human body work together to support the essential life functions of the body. The urinary system is under influence of several other body systems to help it function properly. Which of these CORRECTLY pairs a body system and its influence on the urinary system?
Question 31 options:
The nervous system releases the hormones, ADH and aldosterone, which adjust the rates of fluid and electrolyte reabsorption in the kidneys.
The nervous system monitors distention of the bladder, controlling urination.
The cardiovascular system makes erythropoietin to make new red blood cells.
The digestive system excretes wastes not filtered by the kidneys.
Answer:
The urinary system works with the digestive system and in other systems in your body. It releases the waste from the food they digest and it also works with the circulatory system. It works in other systems in the body to help the body maintain the homeostasis says the Biologists. The waste product is kept dissolved in the liquid (water) and in mammals is stored in a bladder. The work of the kidney inside the body is to maintain acid and water-salt levels of the blood. It releases the waste in the body and it also filters the blood inside of you.
Explanation:
I dont know if this helps but its what I have gotten told. I know its not the exact answer but when i looked up your question its what i got.
Answer:
The nervous system monitors distention of the bladder, controlling urination.
Explanation:
The endocrine system releases the hormones, ADH and aldosterone, which adjust the rates of fluid and electrolyte reabsorption in the kidneys. The kidneys make erythropoietin to make new red blood cells for the cardiovascular system. The digestive system absorbs water needed by the kidneys to excrete wastes.

What gas does a plant release for animals and humans to use? What would happen if that gas was not released from
plants?
Answer:
What gas does a plant release for animals and humans to use?
oxygen
The oxygen that is produced is released from the same tiny holes through which the carbon dioxide entered. Even the oxygen that is released serves another purpose. Other organisms, such as animals, use oxygen to aid in their survival. The whole process of photosynthesis is a transfer of energy from the Sun to a plant.
What would happen if oxygen was not released from plants?
We would be long gone before the oxygen ran out. Assuming only green plants disappeared, we would still have phytoplankton, microscopic algae and bacteria that live in the oceans and photosynthesise the same way land plants do. They are at the bottom of the food chain, so life in the oceans would continue.
We need oxygen to live & plants need carbon dioxide. We need oxygen to breathe & plants need carbon dioxide to make their food (photosynthesis)

The name of two greenhouse gases that may be responsible for the increased ice melting in Greenland includes carbon dioxide and methane. Thus, the correct option for this question is C.
What are Greenhouse gases?Greenhouse gases may be defined as those gases that significantly allow solar radiations to enter but prevent the escape of heat radiations of longer wavelengths. The name of these gases may include carbon dioxide, methane, nitrous oxide, water vapor, CFCs, etc.
Carbon dioxide is the primary greenhouse gas contributing to recent climate change. Carbon dioxide enters the atmosphere through burning fossil fuels, solid waste, trees, and other biological materials.
Apart from this, it is a result of certain chemical reactions, such as cement manufacturing. Along with methane, they are the two greenhouse gases that are also responsible for the increased ice melting in Greenland.
Therefore, the correct option for this question is C.

Why do you think the population growth rate has slowed overall but remains high in less developed countries?
Answer:
Prosperity, Diseases, Education & more.
Explanation:
In continents like Africa you have a lot of diseases and a lot of children who die because of the bad environment, diseases, no food and no water. The education especially the sexual education there isn't good or they didn't even have that topic once in their life. The children are supposed to go to work to give money to the family. More children, more money, right? The biggest reason is poverty and bad education. In China for example they have a problem with too many people, that's why they can get only 1-2 children. In high educated and wealth countries people know it's harder to work with children. The work time, flexibility and more will be much harder with children. People there know about sexual education, how to have safe sex and all those things you learned. I live in Germany and we have a problem with people having no children.

Children are needed in emerging nations as a labor force and to care for their aging parents. Due to the lack of access to contraception and generally lower levels of female education in these nations, fertility rates are higher.
What is population growth?Population growth is defined as the growth due to the fact that the human population is not a static component, one of the main problems of the modern world. The majority of human history saw a relatively steady population size.
Due to outdated customs or a fear of educated women, some nations enforce the absence of education for women. The resources are not available in other nations. Some of the most distant locations, mostly in Africa, are still without access to birth control information. Even fewer people have access to birth control, so unintended pregnancies go uncontrolled.
Thus, children are needed in emerging nations as a labor force and to care for their aging parents. Due to the lack of access to contraception and generally lower levels of female education in these nations, fertility rates are higher.

When the concentration of molecules are equal on both sides of the cell membrane, the water will....
Answer:
Move in and out of the cell evenly
Explanation:
In the passive and active transport, the solute move from lower concentration to higher concentration. In the passive transport cellular energy is not required while in active transport, cellular energy is required.
But, when the concentration of molecules are equal on both sides of a membrane, even though the movement of molecules does not stop and molecules keep their movement in and out of the cell evenly.
Hence, the correct answer is "Move in and out of the cell evenly".

Describe how nitrogen in proteins in dead leaves is recycled to be absorbed by plants? Please help!
Answer:
stages of the nitrogen cycle
1. Nitrogen-fixation
Legume plants such as peas, beans and clover contain nitrogen-fixing bacteria. These bacteria live in swellings in the plant roots called nodules. Nitrogen-fixing bacteria convert nitrogen gas from air into a form that plants can use to make proteins.
Free-living nitrogen-fixing bacteria are also found in the soil. When they die the nitrogen they have fixed into their biomass is converted into ammonium.
2. Feeding
Animals consume plant protein, digest it using specific enzymes and absorb the free amino acids.
3. Production of nitrogenous waste products
Animals cannot store excess protein in their bodies. They break it down and turn it into waste products and excrete them from their bodies.
4. Decomposition
Decomposers (some free-living bacteria and fungi) break down animal and plant proteins (from dead organisms) and nitrogenous waste products to release energy. As a result of decomposition nitrogen is released into the soil in the form of ammonium.
5. Nitrification
A group of free-living soil bacteria called nitrifying bacteria convert ammonium into nitrates in order to obtain energy.
6. Uptake of nitrates
Non-legume plants absorb nitrates from the soil into their roots and use the nitrates to produce their proteins.
7. Denitrification
This is when bacteria in the soil convert the nitrate back into nitrogen gas which then gets released back into the atmosphere.
Nitrogen-fixing bacteria take nitrogen gas from the air and transform it into a form that plants can use to build proteins.
Nitrogen-fixing and nitrogen in proteins:The nitrogen they have fixed into their biomass is transformed to ammonium when they die. In the soil, free-living nitrogen-fixing bacteria can also be discovered.
Nitrogen-fixing bacteria may be found in legume plants such as peas, beans, and clover. These bacteria dwell in nodules, which are swellings in the plant roots. Nitrogen-fixing bacteria transform nitrogen gas from the air into a form that may be used by plants to create proteins.

Explain why gametes cannot be made by mitosis
Gametes cannot be made by mitosis because mitosis does not reduce the chromosome number of the daughter cells.
WHAT IS MITOSIS?
MITOSIS is the kind of cell division in which a single parent cell results in two daughter cells that are genetically identical to one another. The two daughter cells have the same number of chromosomes as the parent cell.WHAT ARE GAMETES?
Gametes are sex cells used for sexual reproduction in certain organisms. Two gametes (one from male called sperm and the other from female called egg) comes together to form a zygote which later grows into a full organism. Note, these two gametes must possess half number of chromosomes as the parent organism.WHY MITOSIS CANNOT PRODUCE GAMETES?
Since mitosis gives rise to same number of chromosomes as parent cell, it is impossible for mitosis to make gametes, which must be half number of chromosomes as parent cell.For example, a somatic human cell contains 46 chromosomes. This means that gametes must contain 23 chromosomes each. However, MITOSIS results in two daughter cells with 46 chromosomes each.
Hence, mitosis cannot make gametes because it does not reduce the chromosome number of the daughter cells.
