B. Cellular respiration
Explanation:
The cellular process that is occurring in the organelle labeled B is "Cellular respiration".
From the image, the organelle B is Mitochondria. Cellular respiration takes in the mitochondria and this is important because it leads in the production of ATP using the chemical energy that is found in glucose and other nutrients.
Mitochondria are known to be membrane-bound organelles. Their function is to generate most of the chemical energy that the cell needs for biochemical reactions.

12. Two teams of scientists hiked 10 kilometers to different study sites. Before their hike, the Valley
team ate a lunch of mostly protein. The Mountain team ate a lunch of a mix of starch and protein, but
hiked at high altitude, where there is much less oxygen. Which team probably had an easier time
hiking?
a
Both teams had an easy time hiking because their digestive systems broke down proteins
into amino acids for cells to release energy.
b
Neither team had an easy time hiking: the Valley team's cells needed more glucose from
broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from
air.
С
The Mountain team had an easier time hiking: their cells released energy from protein
reacting with glucose, which was broken down from starch in the digestive system.
d
The Valley team had an easier time hiking; their cells released energy from protein breaking
down in the digestive system, which then combined with oxygen in cells.
Answers
Answer: B. Neither team had an easy time hiking; the Valley team's cells needed more glucose from broken-down starch for a reaction, and the Mountain team's cells needed more oxygen from air.
Explanation:
Before the hiking by the scientists, we are told that the Valley team ate a lunch of mostly protein while the Mountain team ate a lunch of a mix of starch and protein, but hiked at high altitude, where there is much less oxygen.
Based on the above, none of them had an easier time hiking. This is because since the cells of the Valley team who mostly ate protein, need glucose in order for a reaction to occur. For the Mountain team, even though they are a mixture of starch and protein, they went higher which reduced where there was less oxygen. This will have resulted in a hard time for them.
Therefore, neither had a easy time hiking. The correct option is B.
If a DNA molecule consists of 29% Adenine, how much Thymine will it contain?
Answers
Answer: 29%
Explanation: Remember the base pairing rules: adenine always pairs with thymine (in DNA exclusively; in RNA, where there is no thymine, it will pair with uracil), and cytosine with guanine. Because the nitrogenous bases are always paired rationally, they will always be equal in amount.

Retina provides a sense of vision.
Select one:
a. False
b. True
Answers
Light striking the retina initiates a cascade of chemical and electrical events that ultimately trigger nerve impulses that are sent to various visual centres of the brain through the fibres of the optic nerve. Neural signals from the rods and cones undergo processing by other neurons, whose output takes the form of action potentials in retinal ganglion cells whose axons form the optic nerve.[1] Several important features of visual perception can be traced to the retinal encoding and processing of light.
In vertebrate embryonic development, the retina and the optic nerve originate as outgrowths of the developing brain, specifically the embryonic diencephalon; thus, the retina is considered part of the central nervous system (CNS) and is actually brain tissue. It is the only part of the CNS that can be visualized non-invasively. Ever since you were little, you’ve been hearing lots of hearsay about your eyes and how to keep them healthy. Are carrots really good for your eyes, and will they help you see in the dark? Will reading fine print at night make your eyesight go bad? While many of these are based in fact, they aren’t entirely true. Let’s try to sort the fact from the fiction.
Damage Versus Fatigue
Many of these eye myths involve the threat of damage to your eyes. You may have heard that reading in dim. The retina is an essential part of the eye that enables vision. It's a thin layer of tissue that covers approximately 65 percent of the back of the eye, near the optic nerve. Its job is to receive light from the lens, convert it to neural signals and transmit them to the brain for visual recognition.
In dogs, curly tails are dominant over straight tails. If a pure curly-tailed dog is mated with a straight-tailed
dog, what percentage of their offspring will have curly tails?
Answers
Answer:
75%
Explanation:
If the two genes were equally dominant then the answer would be 50% because you have a 50/50 chance of getting a curly tailed dog. But since the curly tail gene is more dominant, the answer would have to be 75% because you are more likely to get a curly tailed dog.

What causes the change in snowpack levels in the Sierra Nevada from year to year?
Answers
The depth and breadth of the seasonal snowpack in any given year depends on whether a winter is wet or dry. Wet winters (such as 2017 and 2019) tend to stack up a deep snowpack, while dry ones keep it shallow. In 2015, long-term hot and dry conditions in California and Nevada brought snowpack to historically low levels
Which of the following are functions of a lipid?
A) Hold genetic information
B) Do most of the jobs in the cell
C) long term energy, insulation and cushion organs
D) short term energy and structure
Answers
Answer:
Some of the functions of lipids are to provide long term energy, insulation and cushion organs.
Explanation:
Lipids are biomolecules —predominantly formed by carbon and hydrogen— of great importance to the body, since they are the main component of cell membranes and form part of the structure of necessary organic substances, such as hormones.
Within the functions of lipids are found:
Being a reserve energy source, which can be used in the long term. Body lipids serve as thermal insulators, especially when they are found under the skin. The lipids can cushion the internal organs that they cover, protecting them from trauma by body movement or external trauma.the other options are not correct because:
A. The nucleic acids are the ones that store the genetic information.
B. Lipids are an important component of the cell, but they do not do most of the cell's work.
D. They are not a short-term energy source, like carbohydrates.

Why is meiosis important for organism
Answers
Answer:
Meiosis is called as reduction division and it gives rise to four daughter cells which have only half of the genetic information that was present in the parent cell. Hence, it plays very important role in the formation of gametes (egg and sperm). The gametes are essential in the production of zygote which ultimately develops into a new organism.

Answers
Answer:
1- Im not sure, im so sorry! I hope i could help, if I have the answer ill edit this :)
2- When you eat some form of carbohydrate, the body breaks it down into glucose, such as pasta, fruit, bread or sugar. Glucose is absorbed into the bloodstream and, to be used for energy, insulin helps extract it from your blood into your cells.
3- The breakdown of molecules for energy occurs in the muscle region as people work out, which is why people may feel their muscles burning at the end of a difficult workout.
Explanation:
Intro:
Hello!!! Princess Sakura here ^^
Explanation:
1.) Every cell in your body needs oxygen for cellular respiration. Cellular respiration uses oxygen to break down sugar and create energy. The mitochondria are organelles that produce ATP and usually the muscle cells need the most because they are always working.
2.) The carbs you consume converts to blood sugar. So the more carbs you ingest the higher the levels of glucose you'll have released.
3.) It's because as we workout the breakout of molecules for energy happens in the muscle area, and that's because muscles have the most energy and needs the most energy.

Credibility is essentially the believability of the study, and it is determined by both the trustworthiness and expertise of the researcher. Recently, concerns have arisen over Nalgene drinking bottles and the chemicals they may be releasing into the water. Two scientists publish their findings. One who works for a major Nalgene producing company, the other does not. Which scientist is more credible?
Answers
Answer:
The scientist who has no conflict of interest is, in principle, more reliable
Explanation:
All scientific publications must include a Declaration of Interest (also known as Disclosure Statement) by which authors state that there's no personal or financial interest that might be affecting the objectivity of their investigations, results and conclusions. If no conflict exists, the author should indicate that "there is no conflict of interest". In this case, the scientist who works for a Nalgene producing company should state that it is a potential conflict of interest.
