A paramecium uses ATP continuously to beat cilia for locomotion. How does ATP serve the paramecium as a renewable resource?

Biology

Pavel [41]3 years ago

Answer : The correct answer is -

B) ATP is regenerated continuously by the addition of phosphate to ADP.

The continuous supply of energy for ciliary movement in Paramecium is maintained by the help of certain kinases such as adenylate kinase, arginine kinase.

These enzymes continuously regenerate ATP by addition of phosphate to the ADP, giving continuous energy supply for locomotion in Paramecium.

Thus, option B) is the right answer.

The correct answer is B) ATP is regenerated continuously by the addition of phosphate to ADP.

This is a common way of making energy for the body and is even found in humans.

Suppose that you could designan RNA polymerase that would transcibe
lozanna [386]

Answer:

No it would not be useful for cell.

Explanation:

RNA polymerase uses only one strand of DNA which is called the template strand for the synthesis of mRNA. The other strand which is not used to make mRNA is called the coding strand.

If an RNA polymerase is designed which transcribe both the strand than two different strands of mRNA will be generated that will have different nucleotide sequences and will code for different proteins. So one strands will generate a protein which have different amino acids sequence that will complicate the overall process for the cell.

Another problem is if two RNA strands are formed then they can form a double helix and the ribosome might not be able to bind on them and translation might stop. Therefore it would not be useful for cell.

Imagine you are investigating the case of a young man who seems not to respond to stressful situations the same way most people
anzhelika [568]

Answer:

The answer of the human body to stress, and stressful situations, including to conditions that may trigger the stress response of the body, is a pretty complex one involving the nervous system as a whole, and the adrenal glands, which are responsible for producing two of the most important stress-related hormones. These hormones: glucocorticoids and corticoids (cortisol), will in turn affect all body systems in different manners to produce the necessary effects, to respond to the perceived "threat".

In essence, we have a pathway from our brains, to our adrenal glands, known as the hypothalamic-pituitary-adrenal (HPA) axis. In this axis, several genes that are geared towards stress responses activate (CRHR1 and CRHR2, among others) and produce CRH (Corticotropic releasing hormone), which in turn is directly related with stimulating the production of cortisol when there is stress. However, because our bodies are not meant to be in a constant state of alertness and preparation, because the different organs of the body are negatively affected, there are also pathways that will turn off this response and lower the stressful production of cortisol.

In this particular person, although he has been exposed to the same stressor as the others, he does not have precisely the same reactions to it as the others. It is important to note one thing here, and that is, that the stressor offered to these people were videos of stressful situations, and what is known about the stress response is that one vital part of it is visual exposure to different factors, including light, and images. These exposures cause the HPA axis to initiate a response through CRH production. However, it seems that in this young man, although most of the responses are present, not all of them are. So one solution could be that he has a mutation in his genes in his HPA axis, and therefore CRH is not being produced in enought levels to stimulate sufficient levels of cortisol production. However, there are also other genetical reasons why, and these could be many.

kirill115 [55]
Its definitely not A or D because there are 26 weeks in 6 months.

generally, a weight loss of 1-2 lbs per week is reasonable and safe. 

I would say B because it is unrealistic that someone would always lose 2lbs a week

dem82 [27]

Answer:

Rain makes up part of earth's water cycle

Water evaporates from streams, lakes, and oceans, then condensation and precipitation occur in the form of rain.

Explanation:

I'm pretty sure this question is implying that the answers should be directly related to the water cycle. While some of the other sentences might have some truth to them, they are too vague to be considered fact, and they're not necessarily related to the process of the water cycle.
