Answer:

<em>Entamoeba histolytica</em>

Explanation:

<em>Entamoeba histolytica </em>is the causative agent of amebiasis (amebic dysentery). The pathogen enters the human body through consumption of contaminated water or food and enters the small and large intestines. <em>E. histolytica</em> targets the epithelium of large intestine and creates ulcers in it. <em>E. histolytica </em>enter the mucosa and submucosa of the intestine through these ulcers and leads to severe dysentery, that is amoebic dysentery.

Calculate the displacement of the volleyball in sample problem 2f when teh volleyballs final velocity is 1.1 m/s upward
insens350 [35]
The givens are as follows:
initial velocity (vi) = 6 m/sec
acceleration = -9.8 m/sec^2 (the negative sign refers to the direction)
final velocity (v) = 1.1 m/sec
initial position (xi) = 0 meters

Now, we will use the equations of motion to get the displacement as follows:
v = vi + at
1.1 = 6 - 9.8t
9.8t = 6-1.1 = 4.9
t = 0.5 sec

x = xi + vit + 0.5at^t
x = 0 + (6)(0.5) + 0.5(-9.8)(0.5)^2
x = 1.775 meters

kari74 [83]

Answer:

d. neither the light reactions nor the Calvin cycle

Explanation:

Calvin cycle is the name given to a set of chemical reactions that occur in the chloroplast stroma. The chemical reactions that make up the Calvin cycle occur in the carbon fixation step, one of the photosynthesis phases. In this cycle, CO2 is reduced to glyceraldehyde 3-phosphate and ribulose 1.5 bisphosphate, CO2-acceptor, is regenerated.

Photosynthesis is initiated by light reactions, which use light energy to store and transport energy-supplying molecules such as ATP and NADPH.

Neither the Calvin Cycle nor light reactions requires glucose, these processes are initiated by other molecules and are intended to provide products for photosynthesis to occur.
