Which type of feedback is more common in the body?
o positive feedback
O negative feedback
O neutral feedback
O electrical feedback
Answer:
Negative feedback
Explanation:
Negative feedback loops are the most common feedback loops in biological systems. The system acts to reverse the direction of change. Since this tends to keep things constant, it allows the maintenance of homeostatic balance.
Answer:
Negative feedback
Explanation:

Which of the following is false regarding the protein pepsin?
A. Pepsin hydrolyzes peptide bonds.
B. Pepsin is a type of protease.
C. Pepsinogen is the active form of pepsin.
D. Pepsinogen self-cleaves at the pH found in the stomach.
E. None of the above are false.
Answer:
C. Pepsinogen is the active form of pepsin.
Explanation:
Pepsin is a gastric protease belonging to the aspartic proteinase family which breaks down polypeptide chains into smaller peptides by hydrolyzing peptide bonds. Pepsin is found in the gastric juice where it digests proteins from foods together with other digestive enzymes and hydrochloric acid. Moreover, pepsinogen is a precursor of pepsin which is secreted by the gastric chief cells of the human stomach and then is converted into pepsin (its active form) by hydrochloric acid.

A change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore it's function. True or false
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function
Explanation:
The statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.
What are amino acids?Amino acids may be defined as the monomers of the building blocks of proteins. These compounds contain carbon, hydrogen, nitrogen, and oxygen. Amino acids are generally composed of an amino group, a carboxyl group, a hydrogen atom, and a distinctive side chain.
The sequence of DNA is made on the foundation of amino acids along with nucleotides. These sequences govern the special function with respect to their coding and folding. Each sequence specifies a particular protein.
A little change or alteration in these sequences may direct the formation of different amino acids. This completely changes the folding of the protein. This means that the physiology of the protein structure change which also affects its function.
Therefore, the statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.

When viewing the shape of a human cheek cell, what microscope would most likely be used?
A.) Light
B.) Dissecting
C.) Transmission Electron
D.) Scanning Electron
Answer:
Your answer Is C!!!!! :)))
Explanation:
A light microscope can be used to view the shape of a human cheek cell. So the correct option is A.
What is a light microscope?In many research labs, including those using electron microscopes, light microscopes are crucial tools. They can be used to support electron microscopy or as the main viewing tool. The methods used to prepare samples for light microscopy are constantly expanding, and they might include everything from tissue cultures and sliced biological creatures to samples from the sciences of materials and geology.
There are significant parallels between the optical principles of light and electron microscopes. Understanding the operation of a light microscope is essential for both getting the best possible light pictures and comprehending electron microscopy.
We make use of the waveform characteristics of light in microscopy. When generated at a specific source, these waves vibrate perpendicular to the direction of transmission. There are peaks and troughs on every wave. One wavelength is the length of the light ray's onward journey (lambda). The color and intensity of the source affect the wavelength.
Therefore the correct option is A.

A peony plant with straight stamens and red petals was crossed with another plant having straight stamens and streaky petals. The seeds were collected and germinated and the following offspring were obtained 62 straight stamens with red petals 59 straight stamens, streaky petals 18 incurved stamens, red petals 22 incurved stamens, streaky petals a) Which alleles in each pair are dominant
Answer:
Explanation:
From the given information.
Let the Straight stamens be S;
The incurved stamens be s;
The red petals be R; and
The streaky petals be r
The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)
So if SsRr and Ssrr crossed together, Then we have the following:
If SsRr self crossed, we have the following traits = SR Sr sR sr; &
Ssrr = Sr Sr sr sr
Then, the dihybrid cross is:
SR Sr sR sr
Sr SSRr SSrr SsRr Ssrr
Sr SSRr SSrr SsRr Ssrr
sr SsRr Ssrr ssRr ssrr
sr SsRr Ssrr ssRr ssrr

Answer:
B. Not recommended according to IPM.
Explanation:
Integrated Pest Management (IPM) is a sensitive and effective environmental approach to pest management that avoids the use of chemicals and rely on natural methods. some of the methods used by Integrated Pest Management (IPM) are - use mulch in garden areas, use of netting over berry bushes, and use of collars in the soil around susceptible vegetable stems.
So, IPM does not recommend the use of spray on pests as it can affect the crops and they can also get chemically affected.
Hence, the correct answer is "B. Not recommended according to IPM."

What does an increased pulse rate indicate about the heart rate
Answer:
A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body. Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate.
