Cytochalasins bind actin and block actin microfilament assembly. Cells treated with cytochalasins will not divide. How do cytoch

7nadin3 [17]

Answer:

The correct answer will be option-A

Explanation:

Cytochalasin is the metabolic product released from the fungus. The cytochalasin acts a toxin to the cell as it inhibits the division of the cell.

Cytochalasin act by inhibiting the cytoplasmic separation during cell division as it blocks the formation of contractile microfilaments. The presence of cytochalasin inhibits the elongation of acing filament as it blocks the addition of the monomer to the growing end of the filament.

Since it prevents the formation of the contractile rings and cytoplasmic separation, therefore, option-A is the correct answer.

Give the two ways nitrogen can be fixated so plants can use it to grow.

Maurinko [17]

$\huge\mathfrak\red {Answer:}$

<h2>Fixation</h2>

Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:

<h3>Biologically: </h3>

Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.

<h3>Through lightning: </h3>

Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.
