Answer:

dendrites

Explanation:

The neuron consists of a cell body and extensions called dendrites. In some neurons, one of the dendrites is elongated to form an axon. There are terminal and receptor dendrites. Receptor dendrites make contact with terminal dendrites of neighbouring neurons or receptor organs while terminal dendrites make contact with receptor dendrites of another adjacent neurons or effector organs.

nignag [31]

Answer:

Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.

Explanation:

Understand the following.

The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.

The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.

Up to what concentration is carbon dioxide a limiting factor for photosynthesis in low light intensity?
Mariulka [41]

Answer:

<u>Carbon Dioxide limits photosynthesis at a concentration of around 400 ppm (ambient concentration) in low light.</u>

Explanation:

Limiting factors affect the photosynthetic rate, decreasing the potential amount of carbohydrate made via photosynthesis. Carbon dioxide is essential to this form of biosynthesis- it provides the inorganic carbon that is integrated into carbohydrate molecules.

Carbon dioxide is typically present in the atmosphere at concentrations of 0.04%. Light intensity typically cause stomata to open, and increase CO2 uptake. Higher concentrations of CO2  up to 0.1%, cause dramatic increases in the photosynthetic rate.

Low light, thus means less stomatal opening, and less CO2 uptake. As low light intensity can be limiting, it lowers the concentration of Carbon dioxide at which the rate becomes constant.
