how do stars recycle matter?
Answer:
Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations. The material of stars is recycled over billions of years.
Explanation:
The material of stars is recycled over billions of years. Interstellar gas clouds collapse to make stars. Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations.

Answer:
Stars forge heavy elements and return their gas to space. This material enriches gas clouds from which new stars are formed, and the cycle continues. Each generation of stars is made in part from the ashes of previous generations. The material of stars is recycled over billions of years.
Furthermore, Rubin and colleagues find evidence that this new fuel could come in the form of recycled gas once ejected by the galaxy, pushed out by massive supernovae events or by the light pressure of massive newborn stars, but which does not leave the gravitational clutches of the galaxy completely.

According to the National Institute of Health, atrial fibrillation (A-F) occurs if rapid, disorganized electrical signals causing the heart's two upper chambers, called the atria, to fibrillate. The term "fibrillate" means to contract very fast and irregularly. In A-F, blood pools in the atria. It isn't pumped completely into the heart's two lower chambers, called the ventricles. As a result, the heart's upper and lower chambers don't work together as they should. Based on the passage above, how will atrial fibrillation affect blood pressure?
A. It will lower blood pressure because less blood is pumped per beat.
B. It will increase blood pressure because the heart is contracting faster.
C. It will increase blood pressure because the atria fill fully with blood.
D. It will lower blood pressure because blood volume drops in the atria.
Answer:
A. It will lower blood pressure because less blood is pumped per beat.
Explanation:
I thought B might be a potential answer, but since the atria are not filling properly and heart rate is increased, it would make sense that blood pressure drops (effect of faster heart contraction is negated by the drop in blood volume in the atria).

Role of Ibn Sina in the field of medicine?
Answer:
Although Avicenna made advances in pharmacology and in clinical practice, his greatest contribution was probably in the philosophy of medicine. He created a system of medicine that today we would call “holistic” and in which physical and psychological factors, drugs, and diet were combined in treating patients.

Why is absolute dating more accurate than relative dating?
Answer:
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.

how enzymes inhibitions studies in the formulation and development of drugs
Answer:
Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways
Explanation:
An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.

Pesticides often do not just kill the target pest but also poison
inects in and
around the fields. These insects with the pesticides can be eaten by other animals and poison them.
Some pesticides are suspected of disrupting the
of wildlife and people. These
chemicals
because they are fat soluble and get passed up the food chain
by
Unlike pesticides, fertilizers are not directly toxic but their presence in
freshwater and marine areas alters the
system, and in consequence the species
composition of specific ecosystems. Their most dramatic effect is
resulting in an
explosive growth of algae due to
nutrients. This depletes the water of dissolved
oxygen, which in turn can kill fish and other aquatic life.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.

Prompt: You are a carbon atom and you have just been exhaled out of a deer. Describe
the journey that you have been on or describe your new adventures. You should include
at least 10 things that you have learned in Unit 4 (cellular respiration, photosynthesis,
carbon cycle, etc).
Answer:
Cell--vein--heart--lungs--- environment.
Explanation:
The carbon which is produced by the cells in the form of carbondioxide goes with the blood through the vein which carries deoxygenated blood to the heart. After reaching the heart, the heart pumps this carbonated blood to the lungs through pulmonary artery and there this carbon is removed and releases outside the body and oxygen is loaded in the blood. The product of respiration are the reactants of photosynthesis whereas the products of photosynthesis are the reactants of respiration. Photosynthesis occurs in only plants whereas respiration occurs in all types of organism. Carbon cycle is a type of cycle in which carbon moves from atmosphere to biosphere, lithosphere and then again to the atmosphere.
