The act of clapping your hands out in front of you with your elbows fully extended is achieved by contracting the pectoralis major muscles.
The pectoralis major muscle is a thick, large fan-shaped muscle that is located in the chest area of the human body. The pectoralis major is the most superficial muscle in the chest area and its functions is associated with the movement and rotation of the shoulder joint. Body movements such as extending the arm across the front part of the body, lowering the arm to the back part of the body, and rotating the upper arm in an inward manner are achieved by the pectoralis major muscles.
Answer:
The correct answer is: d.a nonpolar side chain.
Explanation:
- Protein can be defined as one of the factors which determine the structure as well as the function of a cell.
- Proteins are composed of polymeric chains of polypeptides, which are made up of amino acid monomers linked to each other by peptide bonds.
- Amino acids can be broadly categorised into non-polar and polar based on the nature of the side chain.
- The non-polar amino acids possess hydrocarbon side-chains which are hydrophobic in nature, so they tend to avoid interaction with water molecules and usually remain in the protein interior. They are uncharged and cannot form any hydrogen bonds with water molecules.
- The polar amino acids possess charged or polar side-chains which are hydrophilic in nature, so they tend to undergo interaction with water molecules and usually remain on the protein surface. They can form hydrogen bonds with molecules of water.
- Beta sheets can be defined a secondary structure of the protein in which the polypeptide sequence forms horizontal strands which are linked to each other by loops. Each strand interact with each other by the formation of hydrogen bonds between the C=O group of one peptide (amide) bond in one strand with the N-H group of another peptide (amide) bond in another strand.
- Apart from these bonds, the non-polar side chains of each amino acid in one strand forms hydrophobic or Van der Waals interactions with the non-polar side chains of each amino acid in the other strand. The polar or charged side chains of the amino acids on each strand form either hydrogen bonds with water molecules or with oppositely charged side chains.
- In the given question, glycine and alanine are non-polar amino acids but serine is a polar amino acid. The side-chains of the non-polar amino acids will tend to face towards the interior of the beta sheet thereby forming hydrophobic interactions with each other, while the serine will tend to face the exterior of the beta sheet so that it can form hydrogen bonds with water molecules.
- As the number of non-polar amino acids is far more than polar amino acids so the effect of non-polar amino acids will prevail in the beta-sheet.
Answer:
Provide information about geography
Explanation:
<em>UAVs are otherwise known as unmanned aerial vehicles or drones. They are usually remotely controlled and monitored from a screen. They can be flown over a large expanse of land to obtain geographical information such as the topography of an area, the distance between two points, the height above sea level, and so on.</em>
<u>Except the UAVs are specially designed and equipped with extra features, they cannot be used to obtain information relating to soil nutrients, soil hydration, or information about plant health on a field. </u>
Hence, the correct answer would be option 1,
Due to the <u>mutation </u>accumulation, the <u>binary fission</u> in bacterial population will decrease due to in ability to divide (Due to inactive replicating enzymes). In the similar way, the <u>generation time</u> will also decrease.
Binary Fission- Binary fission, also known as asexual body division into two new bodies, When an organism divides into two halves (cytokinesis) by binary fission, it doubles its genetic material, or DNA, with each new creature acquiring one copy of the latter.
Generation Time- The amount of time it takes for a colony of bacteria to double in size is known as the generation time. The generation period for various bacteria ranges from a few minutes to many hours. Bacteria multiply by geometric progression because of binary fission.
