How do the respiratory and circulatory systems work together to make gas exchange possible?Giving brainliest to first right answer
Answers
Answer:
Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)
Explanation:
Answer: [SAMPLE RESPONSE] The two systems work together in several ways. First, the respiratory system brings oxygen in the air to the alveoli in the lungs. The circulatory system then delivers the oxygen to the cells. Second, the circulatory system picks up carbon dioxide from the cells and carries it to the lungs, where it is released when we exhale.

4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
of silk. Jamie finds that she can use the pencil to attract the silk. Why does
the attraction occur?
Answers
Answer:
More info given below.
Explanation:
This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.

Why are models important ?
Answers
Explanation:
Models are important in science because a model is a representation of an idea or an object or systems that could be used to describe something that cannot be experienced directly
Answer:
Models allow the scientist to describe objects that are too large or too small to be seen normally, things that don't exist anymore, things that have not been created, and events that occur too slowly or too quickly to be seen. Models also communicate ideas that might be difficult to describe otherwise.
Explanation:
edg. 2020
Another way of saying it would be:
Models are important because it allows scientist to help people better understand a subject that they wouldn't be able to understand, due to that fact that other variables prevent the subject from easily being seen and observed. Models also allow you to explain things in a way that is easier and simpler to explain.

Answers
Answer:
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.
Answer:
It is the engine that drives evolution.
It provides the opportunity to pass outstanding survival traits to the next generation.
It leads to diversity in the range of life forms.
Explanation:
Natural selection explores the differential survival and reproduction of favorable traits transgenerationally.
It is however, the engine that drives evolution. It provides the opportunity to pass outstanding survival traits to the next generation. It leads to diversity in the range of life forms.
There is a species of beetle that has two different color phases. Some have dark, purplish shells with green spots on them; others (same species) have greenish shells with purple spots on them, and there are other varieties that are somewhere in between. The beetles feed on the garden plants and the birds in the area feed on the beetles. When Mr. Jones bought his 200 acre farm, most of his farm was overgrown with an invasive vine that had purple stems and leaves. As he set to work removing these vines so he could farm the land he found many of these beetles on his land. Most of them were the purple color phase, with the occasional green beetle here and there. After several years and lots of hard work he had removed all of the purple vines and replaced them with green soybeans and corn plants. By this time, when he was working in his fields, he noticed that he still saw lots of the beetles, but very few of them were purple. Instead, most of them were the green color phase.
