The correct answer is microglia.
<span>Microglia is glial cells found in the central nervous system with the protective role. Because they are the resident macrophage cells, they act as the first and main form of active immune defense. Microglia is constantly cleaning the CNS for plaques, damaged or unnecessary neurons, and infectious agents, like viruses or other microorganisms.</span>

The sensory cells associated with this sense actually hyperpolarize in response to their stimulus modality...
vaieri [72.5K]

Answer:

Vision

Explanation:

Sensory cells may detect the information like taste, touch, hear and vision by the presence of receptors located on their surface.

Hyperpolarisation may be defined as the change in the cell's membrane potential towards more negative. The sensory vision cells are associated with the hyperpolarisation of cells and makes the cells environment more negative  in response to the stimuli.

Thus, the correct answer is option (d).

Explain the phenomenon of photorespiration, including why it is thought to occur (evolutionarily speaking), and why plants have
liubo4ka [24]

Photorespiration limits casualty products of light reactions that build up in the absence of the Calvin cycle. In many plants, photorespiration is a problem because on a hot, dry day it can drain as much as 50% of the carbon fixed by the Calvin cycle.  The closing of stomata reduces access to CO2 and causes O2 to build up. These conditions favor a seemingly not useful process called photorespiration.  In most plants (C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon compound.  In photorespiration, rubisco adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and organic fuel and releases CO2 without producing ATP or sugar. Photorespiration can evolve relic because rubisco first evolved at a time when the atmosphere had far less O2 and more CO2.

When the patch occupancy rate (c) equals the patch extinction rate (e), patch occupancy (P) is
IgorC [24]

Answer:

When the patch occupancy rate (c) equals the patch extinction rate (e), patch occupancy (P) is 0

Explanation:

According to Levin's model (1969):

<em>dP/dt = c - e</em>

where P represents the proportion of occupied patches.

<em>c</em><em> </em>and <em>e </em>are the local immigration and extinction probabilities per patch.

Thus, the rate of change of P, written as dP/dt, tells you whether P will increase, decrease or stay the same:

  • if dP/dt >0, then P is increasing with time
  • if dP/dt <0, then P is decreasing with time
  • if dP/dt = 0, then P is remaining the same with time.

The rate dP/dt is calculated by the difference between colonization or occupancy rate (<em>c</em>) and extinction rate (<em>e</em>).

c is then calculated as the number of successful colonizations of unoccupied patches as a proportion of all available patches, while e is the proportion of patches becoming empty. Notice that P can range between 0  and  1.

As a result, if the patch occupancy rate (c) equals the patch extinction rate (e), then patch occupancy P equals to 0.
