it allows for nutrients to come into the cell using passive tranport aka moving anything on a gradient without the use of energy (ATP).
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
Answer:
There are over 60, 000 species if trees; however, there are 101 different tree types.
Explanation:
Globally its over 60,065 species of trees but the question asked how many different types of trees are there and the answer is 101 according to www.homestratosphere.com
One way is to see if it responds to stimulants or if it reproduces
<span>Mitosis, simply put, is the division of the nucleus of a cell. It is the phase in the cycle of a cell in which the two chromosomes in a cell divide and separate in a nucleus of their own. These chromosomes are completely identical. As a result of mitosis, two identical cells are formed and are known as daughter cells. This process copies and transfers DNA into both the cells that are formed as a result of Mitosis.</span>
