Both males and female animals have special behaviors to increase their chance of sexual reproduction. Give an example of one of these behaviors.
Answer:
Sexual reproduction increases the chances of acquiring favourable mutations. Aphids, for example, will favour asexual reproduction when their environment is additionally, in most species, females are more likely to provide parental care. Social monogamy is the behavioural pairing of a single male with a single female.
Explanation:
I think this is right but I don't know to be honest.
If it's right then that's good but if it's wrong then sorry I don't have a clue.
Animals have many various traits or adaptations that improve their reproductive success by increasing their probabilities of getting and contending for a mate, protecting their offspring, acquiring resources needed to breed, and helping their genetic relatives.
How do animals increase their chances of reproduction?Animals have adjusted a mixture of courtship and mating behaviours to grow the probability of finding a mate.
For example, the males of many bird species spin their feathers or perform special dances to attract a female.
Thus, Both males and female animals have special behaviours to increase their chance of reproduction.

write a debate conversation on the following topic
Answer:
Person one
We must take measures to reduce our carbon footprint! There are so many options we can take. We can start to produce, and invest in, more solar and wind powered solutions to produce our electricity. We can also cut down on our reliance on gas powered vehicles to move us everywhere. If we were to invest more in electric powered vehicles, start to use more bicycles, or even carpool and take the bus more we could greatly reduce our carbon footprint.
Person two
You talk about all of these “amazing ways” we can reduce our carbon footprint, but you haven’t even considered the inconveniences and the cost of these ways. Solar and wind powered options don’t produce nearly as much power as a coal plant! Not to mention the cost of them. Gas powered vehicles have been around for 100 years, and electric cars haven’t been around for nearly as long and they are very expensive! Also, in the winter, not everyone wants to be freezing cold on a bike, and not everyone has a friend or coworker they can carpool with.
Person one
First of all, I know that these methods would be expensive at first, but if we were to actually take them seriously then they could become inexpensive, and reduce our carbon footprint. The electric car may be newer, but it reduces the carbon output greatly. Investing in these is key in creating a greener future for future generations, and if we don’t reduce our carbon output soon there might not be a planet left for our future generations! All of these methods might seem expensive at first, but in the long run cost will go down, and the high cost at first will be worth it if it means reducing our carbon footprint. Therefore I believe it is necessary that we reduce our carbon footprints, and these are just a few of the ways how.
Person two
You have no way of knowing that the methods would become cheaper over time. They may only grow in cost, while our coal and oil prices have been steady and low for a long, long time. Investing in these ideas would mean taking away money that could be funding more important things such as space travel, or deep sea exploration. Why do you think that there may not be a planet left for future generations? Just because we aren’t reducing our carbon output doesn’t mean we won’t have a planet to live on. I believe that we should not focus on reducing our carbon output because we have much more effective methods of producing electricity and traveling than solar and wind powered devices.
Apossible explanation of or answer to a scientific question that is based on prior knowledge or research and is testable is called a
O law.
O hypothesis.
O theory.
O experiment.
Answer:
The correct answer is hypothesis.
Explanation:
The hypothesis can be defined as a provisional prediction or explanation (as long as it is not tested) of the relationship between 2 or more variables. Thus, the problem-question precedes the hypothesis-answer which, in turn, derives from the objective (s) of the research.The hypothesis, as a formulation that raises a presumed relationship, can be expressed in the form of a proposition, conjecture , assumption, idea or argument that is temporarily accepted to explain certain facts.

A : variety of living things
B :average annual rainfall
C :cover of land area
D :elevation above sea level
Answer is A : variety of living things
Explanation:
Biodiversity, also known as biological diversity is a term used to describe the variety of life on earth across different levels of biological groups. Some scientists have come up with some studies to show that there are over 10,000 species of birds, 200,000 species of flowering plants and almost one million species of insects in the world.
Any environment that is said to have attained the highest level of biological diversity is one that has the most variety of these species of birds, flowering plants and insects.

7. How many ATP molecules are created in glycolysis? What is the net gain of ATP molecules?
.
8. What does NADH do and what will it be used for?
.
9. What is the other product from Glycolysis?
10. Glycolysis does not use oxygen so it is
11. What does fermentation create?
12. Since our muscles do not undergo fermentation, what do our muscles create?
13. The Kreb's cycle and the electron transport chain do use oxygen so they are
14. Where does glycolysis take place in the cell?
.
15. Where does the Kreb's cycle take place in the cell?
16. How many ATP does the Kreb's cycle produce?
17. One of the first reactions breaks down a pyruvate molecule and combines a carbon atom with
something to create
Answer:
7. 2 ATP
8. People use NADH supplements as medicine. NADH is used for improving mental clarity, alertness, concentration, and memory; as well as for treating Alzheimer's disease and dementia. Because of its role in energy production, NADH is also used for improving athletic performance and treating chronic fatigue syndrome
9. Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.
10. It is an anaerobic type of respiration performed by all cells, including anaerobic cells that are killed by oxygen.
11. fermentation, carbon dioxide, is used in bread making and the production of carbonated beverages.
12. i dont know
13. The CO2 produced by the Krebs cycle is the same CO2 that you exhale. The electron carriers NADH and FADH are sent to the final step of cell respiration, which is respiratory electron transport. The Krebs cycle does not use oxygen, though it does stop in the absence of oxygen because it runs out of NAD and FAD.
14. Glycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
15. The Krebs cycle occurs in the mitochondrial matrix and generates a pool of chemical energy from the oxidation of pyruvate, the end product of glycolysis.
16. This produces 2 ATP and 6 NADH , for every glucose molecule entering glycolysis. The Krebs cycle takes place inside the mitochondria.
17. In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide. During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.

Mitosis isn’t just for cancer! Different tissues in the human body naturally divide at different rates. According to your chart, which normal tissue observed divides the most often?
Answer:
Ovary
Explanation:
According to the attached chart, the normal ovary divided the most often with a mitotic index of 55%.
The mitotic index of tissues represents the percentage of cells that are in mitosis compared to the total number of cells present in the tissues.
Generally, cells of cancerous tissues divide more than those of normal tissues and, hence, have higher mitotic indices. In the chart, the mitotic indices of normal tissues ranged from 35 to 55% with the lung having the lowest and ovary having the highest while stomach had the intermediate index.
