A bacterium called Bacillus thuringiensis contains a protein that can kill cotton ballworms and certain other kinds of caterpill

ars. A different bacterium called Agrobacterium tumefaciens has the ability to insert its genetic material into plants.
Scientists in the late twentieth century took a gene from Bacillus thuringiensis and inserted it into specimens of Agrobacterium tumefaciens. Genetic material from the Agrobacterium tumefaciens specimens was then inserted into cotton plants. The goal of these tests was to reduce caterpillar infestation in the cotton plants.

These tests are an example of
A.
natural selection.
B.
genetic modification.
C.
creating purebred species.
D.
meiotic cell division.

Answer:

animal cell

Explanation:

Cytokinesis -

It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.

The process of cytokinesis is different for animal cell and plant cell.

  • Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
  • Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.

Hence, from the given information of the question,

The correct answer is animal cell.

Substance X is a compound containing 632mg of manganese and 368mg of oxygen. Substance X is shown
defon

The empirical formula : MnO₂.

<h3>Further explanation</h3>

Given

632mg of manganese(Mn) = 0.632 g

368mg of oxygen(O) = 0.368 g

M Mn = 55

M O = 16

Required

The empirical formula

Solution

You didn't include the pictures, but the steps for finding the empirical formula are generally the same

  • Find mol(mass : atomic mass)

Mn : 0.632 : 55 = 0.0115

O : 0.368 : 16 =0.023

  • Divide by the smallest mol(Mn=0.0115)

Mn : O =

\tt \dfrac{0.0115}{0.0115}\div \dfrac{0.023}{0.0115}=1\div 2

The empirical formula : MnO₂
