Answer:
1.25 µm
Explanation:
The cell will have a length dimension that is 1/40000 times the length of the image:
(50·10^-3 m)/(40·10^3) = 1.25·10^-6 m = 1.25 µm
The three main features of a prokaryotic
cell
We have its insides:
<span><span>1.
</span>Cytoplasm. Cytoplasm
is where its organelles are suspended.</span>
<span><span>2.
</span>Ribosomes. These
ribosomes facilitate in manufacturing the cell’s proteins used in many cellular
activities.</span>
<span><span>3.
</span>Plasmid. It
is a tiny DNA molecule.</span>
<span><span>4.
</span>Nucleoid. The
genophore of a prokaryotic cell where its genetical material are found.</span>
Externally prokaryotic cells
have:
<span><span>1.
</span>Capsules.</span>
<span><span>2.
</span>Flagellum. A
tail</span>
<span><span>3.
</span>Pili. A hair-like
structure on its surface.</span>
Answer:
<u>a) strong joints with restricted movement.</u>
Explanation:
Joints which are closely fitted cannot allow free movement because movement requires space in the joint so the bones can move in this space. So a closely fitted joint allow restricted or no movement at all. Weak joints with restricted movements are called weak because they are not well fitted closely. Strong joints with restricted movement is closely fitted, one of the example is joints of skull.
Go to quizlet thats where i had found the answer at :)
Answer:
a. Light and carbon reactions occur in separate cells.
b. ATP is used to move a three-carbon ferry molecule from bundle-sheath cells back to mesophyll cells.
c. They require less water to live.
g. These plants function better in the hot, sunny environments.
Explanation:
The plants which carry out C₄ pathway or Hatch and Slack pathway are called C₄ plants. Examples are maize, sugar cane, sorghum. They live in hot, dry or arid habitats. C₄ plants have dimorphic chloroplast. The chloroplast is in bundle sheath cells does not have grana and in the spongy mesophyll cells have chloroplasts with grana. So, light and carbon reactions occur in separate cells. C4 plants are more efficient in photosynthesis than the C₃ plants. There is no photorespiration in C₄ plants as Phospshoenol pyruvate (PEP) carboxylase enzyme.
