If someone shakes your hand, the proteins that change shape and are responsible for initiating the feeling of this hand touch pr
dangina [55]

Answer:

d. dynamic receptor proteins

Explanation:

In the skin there are several receptor cells that can pick up various stimuli such as temperature, pressure and pain. They can be classified into mechanoreceptor, thermoreceptor and pain receptor cells.  When we are dealing with mechanical stimuli like pressure, mechanoreceptors respond to stimuli by sending the signal to the brain.

Light touches on the skin are received by nerve endings called Meissner corpuscles and Merkel discs. Already more intense pressures (such as a handshake) are received by receptors called Pacini corpuscles.

The electron transport chain is composed primarily of what biomolecule?
lys-0071 [83]

The correct answer is proteins.

The oxidative phosphorylation in the eukaryotes takes place within the mitochondria with the help of electron transport chain. The main objective of the electron transport chain is to accumulate enough amount of protons in the intermembrane space so that there will be a concentration gradient which would help in the production of ATP.  

The electron transport chain comprises of various molecules, but majorly the proteins, which are situated in the inner membrane of the mitochondria.

first, drag the labels of group 1 to their respective targets to identify the types of sugars and the type of reaction shown.
Tasya [4]

drag the labels of group 1 to their respective targets to identify the types of sugars and the type of reaction shown .Disaccharide is created when a monosaccharide undergoes a dehydration event (loses water).

nomenclature and structures

The word "carbohydrate" refers to the majority of simple carbohydrates, which have the general elemental composition Cx(H2O)y. It is derived from the German "kohlenhydrate" and the related French "hydrate de carbone." According to the following imbalanced equation, their composition is related to the fact that they are created by photosynthesis from carbon dioxide and water:

Sugar + O2 + CO2 + H2O

The vast majority of naturally occurring carbohydrates present in living things, however, do not have the straightforward empirical formula Cx(H2O)y. Instead, the majority of naturally occurring carbohydrates are composed of oligomers (oligosaccharides or polymers (polysaccharides [Chapter 4]) by combining sugars with the other components of other molecules monosaccharide.

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. ​​​​​​​ To have enough DNA
ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
