Answer:

The human eye does not rotate, nor does it turn in search of sunlight to form a power source.

The human eye contracts its pupillary structure in order to collimate or select the rays of light that enter the eye, while the plant cannot make a selection or filtering of solar rays.

The human eye has three different types of cones and plants do not have the cone system.

Plants can absorb sunlight and rotate toward the beam up to 360 degrees while the human eye cannot.

Explanation:

The comparison between the human eye and this type of plants at the time of solar irradiation presents many differences, but the most important thing of all is that the human eye can regulate the entry of irradiation while the plants rotate towards where the ray of the sun but they cannot regulate how much sun they perceive by means of a filtering such as the contraction of the cornea

A scientist thinks that a certain chemical is a mutagen. She exposes plant cells to a large amount of this chemical in the labor
PSYCHO15rus [73]

A mutation is an alteration in the original DNA sequence.  Option 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material.

Mutations alter DNI sequences and introduce new variants. Many of these variants are eliminated, but some of them might succeed and be incorporated in each individual, affecting the entire species.

They can be damaging or beneficial. These last mutations are the ones that have been selected by natural selection.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level. They can change the bases sequences and bases pairing.

Mutations depend on each group's environment and its ecological pressures, and they accumulate in time. They are inherited to the followings generation and get to spread.

According to this framework, the correct option is 3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.

If the analyzed chemical is a mutagen, then it will cause an alteration in the DNA sequence and this change -mutation- will pass to the following generations spreading in the population.

the laboratory

Which statement best provides evidence that the substance is a mutagen?

  1. The cells die within hours of being exposed to the chemical.
  2. The cells grow more quickly than those that were not exposed to the chemical.
  3. The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
  4. The cells continue to divide at the same rate as before they were exposed to the chemical.

Answer:

Your nervous system is involved with all aspects of human function.  Circulation, digestion, endocrine and excretory systems are controlled by the autonomic nervous system.  The autonomic nervous function is controlled by your body with out conscious thought.  Imagine having to regulate your heart rate, rate of digestion, liver, and hormones with your mind.  The brain and spinal cord work together to carry out these tasks.

Breathing is another example of your body systems working together.  When you breathe, you think of the respiratory system.  However, think about what the respiratory system does.  It delivers oxygen (nutrients) and removes carbon dioxide (waste).  However, the respiratory system only exchanges these gases through the lungs.  These gases need to travel throughout the entire body.  The circulatory system allows the gases (and blood) to travel everywhere.  The skeletal and muscular systems are also involved because they help push the blood from one end of the body to the other.

the skeletal system and its interaction with the nervous system. For example, the skull protects the brain from injury. The brain also regulates the position of the bones by using the muscular system

A third example is when a pathogen enters the body.  Your immune system is responsible for keeping invaders out.  When you breath in a pathogen, it can sometimes cause you to cough.  Your immune system recognizes the invader and communicates to your body that it is bad.  Then your skeletal and muscular system is responsible for creating the contractions to create the cough.
