What are 5 factors that decrease populations (explain each or tell how that factor causes a decrease in a population).

Answers

Answer 1

Answer:

Morality and Emigration

Explanation:

Mortality and emigration decrease the population. Thus, the size of any population is the result of the relationships among these rates. Natality, mortality, immigration, and emigration rates apply to every population, including the human population. The sum of these rates makes up the growth rate of a population.

Answer 2
1) Agricultural Change:
agricultural changes have been massive over the past 400 years. Many of these agricultural changes even at a low level free up workers from the farms. This allows industrialisation which needs lots of workers and tends to promote high birth rates. The more regular supply of food from advanced farming also promotes birth rates, as people are sure they can feed their children, and reduces famine deaths.

2) Education:
Education plays a vital role in determining the levels of both birth and death rates in a country and hence the level of population growth. As education levels increase people tend to have fewer children so that they can focus their resources in improving the life chances of those few children.

3) Emancipation of women:
In many rich countries women have become over time free to work when they want within their life. This is not the case in all countries in the world where many women are stuck in gender specific unpaid work such as maintaining a household and subsistence farming plots. Women are much more likely now to go to university and work for a few years before having their first child. This can result in fewer children being born per woman as fertility declines with age for women.

4) Urbanization:
It has a significant impact upon population growth because it can impact upon the birth and death rates of a country. As a country becomes increasingly urbanised the birth rate tends to rise and death rates tend to fall.

5) Death rates:
Often death rates are reduced before a slowdown in birth rates, causing a boom in the population size at a certain point in a country’s economic development. Death rates fall and life expectancy increased.

Investigate four substances containing nitrogen or phosphorous that are related to biological processes, and explain their respective roles in those processes. (Examples: DNA, RNA, amino acids, and enzymes).

Answers

Answer:

Well, you already have the answer, but I can try to elaborate XD

So, DNA: contains genetic information that is necessary for biological functioning and reproduction.

More specifically, it contains the genetic instructions through gene encoding that instructs the cell what to do. A specialized complex ribosome interacts with the DNA molecules and "reads" it, changing the genes from the DNA into proteins that the cell as a whole can function upon. It is also crucial to forming a whole cell in offspring, since only the genes from the two parents combined (in humans at least) can produce an offspring with all genes intact. Those who do not have genetic disorders, a famous one being Down Syndrome.

Next, RNA: a molecule necessary for expressing genes and making proteins.

Connecting to the paragraph above for DNA, RNA also assists in the process by reading the ribosome that reads the DNA itself. Complicated, I know. All you have to know, however, is that the RNA, in this case called mRNA since it serves as a messenger, hence, the "m", reads the codons produced by the ribosome when it reads the DNA, and makes proteins according to those codons, and those proteins then scatter all across the cell to execute instructions.

Now, we move onto nitrogen and phosphorous: both are found in amino acids, the building blocks of proteins.

That is actually partially wrong. Amino acids do not contain phosphorous, but do contain nitrogen. Not exactly sure what went wrong on your end there, but nitrogen is a basic building block for amino acids, which are basic building blocks themselves for proteins. To be more clear, amino acids are made of carbon, hydrogen, oxygen and nitrogen atoms. No phosphorus there!

Finally, enzymes: special proteins that accelerate chemical reactions in cells.

This is correct. Enzymes typically lower the activation energy required for reactions to happen. More specifically, enzymes make the reaction molecules more active, hence, lowering the threshold for the amount of energy you have to put in before the molecules start crashing into each other hard enough to have a chemical reaction. Of course, enzymes do not participate in the reaction itself, which makes them incredibly useful for spurring on chemical reactions since they can be used multiple times.

QUESTION: this for the other version.. " Investigate substances containing carbon or oxygen that relate to biological processes. Explain their main function in those processes. "

ANSWER: I chose to investigate four substances: carbon dioxide, ethanol, glucose, and cellulose. According to my research, these are the main functions of these substances in various biological processes:

Carbon dioxide: Carbon dioxide is a product of aerobic respiration. Most living organisms exhale carbon dioxide while plants inhale it in the respiratory process. Carbon dioxide is converted to organic matter in the process of photosynthesis carried out by autotrophs.

Ethanol: The process of fermentation gives rise to ethanol, which is an alcohol. Ethanol is formed through a type of anaerobic respiration, that is, respiration without the use of oxygen.

Glucose: Glucose is a form of carbohydrate. It is nothing but simple sugar that stores energy in plants and animals.

Cellulose: Cellulose is an organic polymer used to make cell walls in plants.

Structural and behavioral adaptations affect the reproductive success of plants and animals.
A. True
B. false

Answers

I’m not sure I think true/false

Structural and behavioral adaptations can indeed impact the reproductive success of plants and animals. Adaptations are traits or behaviors that help organisms survive and reproduce in their environment. The statement is true.

Structural adaptations refer to physical features or characteristics that organisms possess. For example, plants may develop specialized structures like flowers, fruits, or seed dispersal mechanisms that enhance their reproductive success. Animals may have specific anatomical features like camouflage, protective shells, or specialized reproductive organs that increase their chances of successful reproduction.

Behavioral adaptations, on the other hand, involve actions or behaviors that organisms exhibit. These behaviors can include courtship rituals, mating displays, migration patterns, or parental care. Such behaviors help attract mates, establish territories, protect offspring, and ensure the successful transfer of genetic material.

Therefore, the statement is true.

what would happen if your body failed to return to normal after exercising? explain.

Answers

Answer: if your question has to do with homeostasis here you go! i hope this helps:)

In order for a body to work optimally, it must operate in an environment of stability called homeostasis. When the body experiences stress—for example, from exercise or extreme temperatures—it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down.

The loss of too much blood may lead to circulatory shock, a life-threatening condition in which the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues to maintain cellular metabolism.

Answers

Answer:

The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)

Explanation:

Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.

Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease  common with ketoacidosis is Diabetes.

The answer is Mitochondria. I took the test and that's the correct answer.

Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.

What is mitochondria?

Mitochondria are membrane-bound organelles (mitochondrial, singular) that produce most of the chemical energy required for biochemical reactions in cells.

The chemical energy produced by mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Mitochondria contain their own small chromosomes. In general, mitochondria, and thus mitochondrial DNA, are inherited only from the mother.

Therefore, Energy conversion within a plant cell would be limited most severely by removal of the cell's  by mitochondria.
