<h2><u>Full Question:</u></h2>

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

<h2><u>Answer</u>:</h2>

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

<h3><u>Explanation</u>:</h3>

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.

Describe the accepted theory during redi's time explaining the origin of the flies

densk [106]

During the time of Fransesco Redi, the 17th century, people believed in spontaneous generation of organisms from non-living thing, or abiogenesis.

The people of that time believed that living things, such as flies, arise from non-living things spontaneously. Fransesco Redi challenged this belief and set up the famous fruit fly experiment to demonstrate that life comes from pre-existing life, and not from non-living things such as meat and fruit.

Which of the following is most consistent with homeostasis? Select one: a. As blood pressure falls, blood flow to cardiac (heart

alex41 [277]

Answer:

Both C and E are reasonable answers.

Explanation:

Homeostasis describes the body's ability to maintain a stable equilibirum. In other words, if the body experiences a stress, it will generate a response that works to counteract that stress and restore itself to how it was prior to the stress.

A. This describes a cause and effect (BP down --> venous return down). It does not describe an active physiological response to counteract the BP drop such as an increase in heart rate. Not homeostasis.

B. Again, a cause and effect is described. Blood vessel walls becoming thinner is not a response to counteract increased BP. Not homeostasis.

C. Here a response to a stress is described. Men are drinking more water. The body responds by getting rid of that water, restoring the body to its former state. This describes homeostasis.

D. This sounds like homeostasis, but it's actually the opposite of what happens. Dilation of peripheral blood vessels is a way for the body to get rid of heat. This is the opposite of what you would want if the body got colder - it would make the stress worse, which is the opposite of homeostasis. In actuality the response to cold temperature is constriction of blood vessels to preserve heat.

E. This deescribes homeostasis. The stress is increased glucose. The body's response to manage it is to release insulin, which helps remove the glucose from circulation.

Match each scenario to its related biomolecules. Jack is eating a diet that will help him build muscle, so he eats a diet high i

Stells [14]

The options for this question are as follows:

A. Nucleic acids

B. Carbohydrates

C. Fats

D. Proteins

Now the correct answers of the match are as follows:

Jack is eating a diet that will help him build muscle, so he eats a diet high in this. <u>D. Proteins</u>

Explanation: Proteins help to build up the muscles. That's why people who want to do body-building, eat protein rich foods, like chicken, eggs, soy, etc.

Before a race, Ruth drinks a beverage full of this biomolecule to get energy. <u>B. Carbohydrate </u>

Explanation: This biomolecule provides instant energy to our body. For example, glucose is consumed before race, as dissolves quickly in our blood and provides instant energy. Glucose is an example of simplest carbohydrate.

These molecules in olive oil will help Ruth’s body store long-term energy. <u>C. Fats </u>

Explanation: Fats are the kind of biomolecule which is stored in our body in the adipose tissues. Also, when glucose is all used up by our body cells, the body starts to get energy from this stored fat.

Elizabeth has been advised to go for genetic screening to detect any abnormalities in her unborn child. <u>A. Nucleic acids </u>

Explanation: Every cell of our body has DNA, and it contains all the genetic information about the whole body. DNA is a kind of nucleic acid. If Elizabeth is going for test of the abnormality, it means she is going to test for the DNA of her child.

Ostrovityanka [42]

Answer:

This conversion of one form of energy to another is called energy transformation.

Explanation:

Eye is one of the most important sensory organ of our body that helps in the perception of light.

When we see a light at that time light energy is converted into neural messages and then carried to the brain by ophthalmic nerve for processing.

Here the law of conservation of energy is maintained which states that energy cannot be created nor destroyed, energy can only be transformed.
