The English moth, Biston betularia, is often cited as an example of observed evolution. There are two colors of this moth, light

and
dark (typica and carbonaria). Kettlewell found that dark moths constituted less than 2% of the population prior to 1848. Then, the
frequency of the dark coloration began to increase. By 1898, the 95% of the moths in Manchester and other highly industrialized
areas were of the dark color. Using the moth example, analyze the events in order to identify support for the statement: natural
selection changes populations, not individuals. Choose ALL that apply.
A)
Variation in the population existed.
B)
Color variation is a result of different gene combinations.
C)
In response to environmental change, moth coloration changed from light
to dark.
D)
Due to natural selection, the ratio of different genetic combinations is
changing
E)
Predator pressure resulted in the light colored genotype being removed
from the gene pool.

(opening the door) describe the work of at least 3 body organ Systems that work during the process.
My name is Ann [436]
Explanation:

When a person opens the door, he or she uses 3 systems:

1. Nervous system: from the nervous system, neural instructions are generated through electrical impulses towards the muscles of the upper limb so that they make the necessary movements to open the door.

2. Muscular system: through the muscles of the trunk and the upper limb, it generates voluntary movement to open the door.

3. Skeletal system: the bones are the support of the soft tissues and the fulcrum of most of the skeletal muscles. In this sense, it serves as a support for the muscles of the trunk and the upper limb to carry out the movement of opening the door.

we can conclude that the correct answer is:

Answer:

1. Nervous system: instructions are generated from the nervous system by means of electrical impulses towards the muscles of the upper limb so that they carry out the necessary movements to open the door.

2. Muscular system: the muscles of the trunk and the upper limb generate voluntary movement to open the door.

3. Skeletal system: it supports the muscles of the trunk and the upper limb to carry out the door opening movement. It also has joints that help the mechanical movements necessary to open the door.

What role do nerve cells play in the human body? They allow the body to react to stimuli. They regulate the exchange of chemical
Alex

The right option is; They allow the body to react to stimuli.

Nerve cells, (also called neurons) are specialized cells that are found in their millions in the nervous system. Nerve cells are created to stimulate other cells in the body.  They transmit messages in the form of electrical signals within the body, and they allow the body to respond to stimuli. Neurons are grouped into three types which are; sensory neurons, motor neurons and association neurons.
