Answer:
Breathed out air includes more carbon dioxide than breathed in air because carbon dioxide is generated in our bodies throughout the breath cycle as a result of food oxidation. As a result, it is expelled from the body upon exhalation.

What are the characteristics of muscle?
Answer:
-It thrives during times of intense, or sustained, physical activity.
-The need for increased carbohydrates to sustain that extra level of exertion.
-It's the primary tissue in the human body with herculean strength which makes it very efficient at doing heavy work.
-It becomes rigid when it becomes depleted of oxygen, which is what causes cramping around muscles during intense bouts of exercise where you are doing something like sprinting or weight lifting too fast for your body to keep up through oxygenation alone. This is called anaerobic glycolysis - where there isn't enough oxygen present to use all the sugars being metabolized by your muscles even NEEDED by their quick contractions.

What benefits do you see in genetic testing, if any?
What concerns do you have about genetic testing, if any?
Would you want doctor prescribed genetic testing/screening done?
Would you want voluntary genetic testing/screening done (e.g. 23 and me)?
Answer:
Genetic testing has potential benefits whether the results are positive or negative for a gene mutation. Test results can provide a sense of relief from uncertainty and help people make informed decisions about managing their health care. For example, a negative result can eliminate the need for unnecessary checkups and screening tests in some cases. A positive result can direct a person toward available prevention, monitoring, and treatment options. Some test results can also help people make decisions about having children. Newborn screening can identify genetic disorders early in life so treatment can be started as early as possible.

Three pieces of evidence of universe expansion support the Big Bang Theory. The first piece of evidence, which Edwin Hubble discovered, is that_____
The second piece of evidence is the change in universal temperature. The temperature_____
The third piece of evidence is that Cosmic Microwave Background radiation is found______
:: uniformly across the universe
:: has increased dramatically
:: galaxies are moving toward each other
:: galaxies are moving away from each other
:: has decreased dramatically
1)a distant luminous object travels rapidly away from an observer.
2)Dark matter provides the gravity that allows the stars to rotate at the same speed.
3)1 galaxy is moving away from each other 2 has decreased dramatically 3 uniformly across the universe
4)1 matter 2 formations of galaxies 3 remained uniform
5)Nuclear fission takes place in the core of stars.
6)The gravity of dark matter distorts light from distant sources.
7)They both occur in the nucleus of an atom. -They both release large amounts of energy.
8)It is the proportion predicted to be present in the early universe.
8)Through dark energy, the universe is expanding at a faster and faster rate. -Because of dark matter, gravitational interactions cause galaxies to develop.
9)It verifies that the early universe was once extremely hot.
Hello, Connexus friends hopes this helps this is all the review questions + they correct cuz I got 10 out of 10 let me know if you need help!
The first piece of evidence Hubble has discovered is that galaxies are moving away from each other. The second piece of evidence is that the universal temperature has increased dramatically. The third piece of evidence is that cosmic microwave background radiation is found uniformly throughout the universe.
We can arrive at this answer because:
The Big Bang theory claims that the universe and all of its elements arose from a strong explosion.Although it is a debated and questioned theory, Edwin Hubble found evidence that proves its veracity and is accepted by many scientists.Within this evidence, Hubble claims that the universal temperature continues to increase drastically, which causes the galaxies to move away.The Big Bang was generated from a large amount of pressure and temperature, which caused the universe to expand, so Hubble's evidence may be true.Furthermore, Hubble claims that cosmic microwave background radiation is found uniformly throughout the universe and that this is a trace of the Big Bang.

Pseudopodia is temporary .........
a. cell
b. cilia
c. part of cell
d. locomotary organ.
Pseudopodia are temporary projections of the cell membrane of eukaryotic cells. And by temporary, it means that it is not a fixed structure. Single-celled organisms characterized by the ability to form arm-like protrusion that can be protracted or retracted are referred to as amoebae.
There are many points during the cell cycle when the process of division may stop because of a problem. Sometimes the process doesn’t stop. Summarize the function of apoptosis in the cell cycle.(1 point)

to repair damaged or old cells
to repair damaged or old cells
The function of apoptosis in the cell cycle is to destroy damaged and/or old cells. In this case, we can consider that the first answer option is the correct option.
Apoptosis is a programmed death, where the cells promote massive destruction when they "realize" that they can create problems for the organism.
This process takes place as follows:
A cell retraction begins so that the cell cannot adhere to other cells or substances.The chromatin becomes condensed.The cell membrane elongates, forming structures known as "blebs."The cell nucleus disintegrates completely.The blebs break off, forming an apoptotic body.The apoptotic body is unprotected from the action of phagocytes that can destroy the molecule.More information:

Myelin Sheath has a fatty layer that insulates the axon.
True OR False
Answer:
True
Explanation:
Myelin is a lipid-rich (fatty) substance that surrounds nerve cell axons (the nervous system's "wires") to insulate them and increase the rate at which electrical impulses (called action potentials) are passed along the axon. In the CNS, axons carry electrical signals from one nerve cell body to another. ...
