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.

Explanation:
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.

Do you think animals pollinate flowers and disperse seeds on purpose or by accident?
Answer:
Animals most likely pollinate by accident.
Explanation:
Deer for example, they may graze in the grass. The pollen/seeds could catch onto their fur--and later fall off into a different area when they walk away. They could also eat a plant, and the seeds end up in their feces. Bees for another example don't necessarily mean to pollinate, they just happen to pick up pollen/seeds when they land on a flower for honey.

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.
Which of the following is a community?
A. All of the nonliving things that make the lake inhabitable O
B. All of the fish, bacteria, and mammals that live in a lake
C. All of the living and nonliving things that interact in and around a lake
D. All of the trout that live in a lake
Answer:
B. All of the fish, bacteria, and mammals that live in a lake
Explanation:
In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.
Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.
Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".

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.
