Hot air balloons float because the air within the balloon is heated by a burner, making it less dense than the air around it, allowing the weight to get lifted from below. Gas balloons may be filled with either helium or hydrogen and use sand as ballast.
Explanation:
which is not involved with an inflammatory Response
A. Fever - increased temperature
B. Slowed blood flow
C. White blood cells move to the area of infected
D. inflammation in area
This is an inflammatory reaction to an infection in the body. Option D is correct.
What is the inflammatory response?When tissues are harmed by toxins, germs, trauma, heat, or any other cause, the inflammatory response (inflammation) ensues. A fever is induced by the body's attempt to destroy any infections with heat.
Histamine, bradykinin, and prostaglandins are among the substances released by injured cells. Because of these substances, blood vessels leak fluid into the tissues, producing swelling.
White blood cells migrate to the affected location to destroy any germs. Because white blood cells are primarily intended to aid in the killing of infections, sending white blood cells to destroy the pathogen is an inflammatory reaction.
Finally, inflammation results from the body's attempt to cleanse the contaminated region of microorganisms. Similar to the label “inflammatory,” the body will frequently create inflammation in an attempt to cleanse the body of any undesirable infections.
Therefore, option D is correct.

A cell uses active transport to move sodium ions out of the cell. Why does the cell use active transport instead of diffusion to move sodium ions out of the cell?.
Answer:
A cell uses active transport because active transport uses energy going from high to low (against the concentraion gradient) while diffusion (passive transport which doesn't use energy) goes from low to high.
Explanation:
The cell uses active transport to move sodium ions out of the cell instead of diffusion because they are moved against a concentration gradient.
WHAT IS ACTIVE TRANSPORT?Active transport is the type of transport in which substances are moved from a region of higher concentration to a region of lower concentration.
This means that substances are moved against a concentration gradient, hence, requires energy in form of ATP to take place.

what determines how closely related 2 species are?
Answer:
Before: (Darwin did) Physical features and behavior
Now:
DNA Testing
Explanation:
Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are. However, now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive. One example of looks being deceptive is: The bat and the crow both have wings, and the squirrel does not. From this, one may think that bats and crows are more closely related than bats and squirrels, while the opposite is indeed the case.
