Given what you know about the endosymbiotic theory, which region of the chloroplast below would you expect to be derived from th
san4es73 [151]

Answer:

Photosynthetic lamellae

Explanation:

The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.

The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  

The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.

Thus, Photosynthetic lamellae are the correct answer.

Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?
MrRissso [65]

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.

Which of the following is a factor that determines the rate of impulse propagation, or conduction velocity, along an axon?a) len
Alexxx [7]

Answer:

c) degree of myelination of the axon

Explanation:

Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.

Factors that determines the rate of conduction velocity are:

  • axon diameter-larger diameter axons have a higher conduction velocity
  • sheeth-a myelin sheath increases the rate of impulse propagatio

Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
