Answer:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.
I think the correct answer from the choices listed above is option A. In plants, the purpose of auxins is to produce phytochrome. The main function of auxin is to help plants grow. Auxin stimulates plant cells to elongate, and the apical meristem of a plant. Hope this answers the question.
Answer:
The correct answer will be option-B
Explanation:
Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.
The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.
The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.
Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.
Thus, Option-B is the correct answer.
We can learn the beliefs and practices of people in the community by community immersion or we will live in there community to observe and interact with the people (participant observation). Doing an initial community diagnosis will identify the most significant health problem in the community. Doing a participatory action research will also make us understand disease in the community.
