Ray Of Light [21]

Answer:

<em>They will have a large number of genetic variations.</em>

Explanation:

Genetic variations arise due to sexual reproduction or due to the process of meiosis.  

Cross-pollination can be described as a process in which the pollen of one flower is transferred to another flower. The pollen when fertilizes the egg in the stigma, will produce offspring with varied genetic characteristics. This will be because the pollen would carry the trait of another flower and the egg of another flower. This will lead to many genetic variations.

Answer;

-Sympathetic nervous system

After cheering wildly at an exciting football game your body may begin to relax on the way home. This relaxation reflects activity of the sympathetic nervous system.

Explanation;

The sympathetic nervous system is part of the autonomic nervous system, which also includes the parasympathetic nervous system.

The sympathetic nervous system activates what is often termed the fight or flight response. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons. Sympathetic neurons are frequently considered part of the peripheral nervous system (PNS), although there are many that lie within the central nervous system

Ann took 4 glasses of water with different colors, then placed cabbage in it. She observed the setting before and after 8 hrs. W
maw [93]

Plants absorb water from the ground. In the experiment, we can see that cabbage leaves take water from the glasses through the process of transpiration. Together with water the leaves absorb the pigments.

<h3 />

Experiment      

1) Four glasses of water, each with a different color ⇒ red, blue, yellow, orange

2) One or two cabbage leaves are placed in each glass and left there for eight hours.

3) After 8 hours, the leafs turn into the color of the colored-water in which they are placed.

<h3>Explanation</h3>

When placing cabbage leaves in the glasses, they start to absorb water from the stems.

As they absorb water to drive it to other parts of the leaf, they also absorb the pigments that are giving color to the water.

As time passes by, the leaves acquire the same color as the water.

<h3>Water absorption: Transpiration</h3>

Plants absorb water from the ground. This process is known as transpiration.

Roots are the first organ that gets in touch with water.

The xylem in roots and stems is in charge of this process.

The xylem composes the vascular system that transports water and minerals through its vessels and tracheids from the roots to the aerial parts of the plants.

Water can move from the ground to the aerial parts of the plant thanks to osmosis and hydric gradient potential.
