Answer the following question given this paragraph: When we consider a chemical reaction, we need to take into account both the system and the surroundings. The system includes the components involved in the chemical reaction itself. These will often take place in a flask, a beaker, a test tube, or some other container. The surroundings include everything that is not part of the system. When potassium reacts with water, part of the heat energy generated in the reaction is released into the surroundings. The boundary between system and surroundings is arbitrary, and it is generally chosen in a way that makes observations and calculations easier. Q: When we consider a chemical reaction, we need to take into account both the system and what? Choices: - date - fluctuations - time - sorroundings A:
(Answer)
sorroundings
Ques: Answer the following question given this paragraph: Q: During which process in bacteria do the chromosome replicates and the two daughter chromosomes actively move apart? Choices: - function fission - secondary fission - matter fission - binary fission A:
Ans: binary fission
(Q).
Answer the following question given this paragraph: After spermatids form, they move into the epididymis to mature into sperm, like the one shown in Figure below . The spermatids grow a tail and lose excess cytoplasm from the head. When a sperm is mature, the tail can rotate like a propeller, so the sperm can propel itself forward. Mitochondria in the connecting piece produce the energy (ATP) needed for movement. The head of the mature sperm consists mainly of the nucleus, which carries copies of the father's chromosomes. The part of the head called the acrosome produces enzymes that help the sperm head penetrate an egg. Q: After spermatids form, they move where to mature into sperm? Choices: - into the prostate - into the volaris - into the vans deferens - into the epididymis A:
(A).
into the epididymis
Ques:Answer the following question given this paragraph: In vascular plants, the sporophyte generation is dominant. In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of leaves. The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows. Q: In vascular plants, the sporophyte generation is what? Choices: - submissive - evident - fast - dominant A:

Ans:dominant
Ques: Answer the following question given this paragraph: Chemistry in Everyday Life Statue of Liberty: Changing Colors The Statue of Liberty is a landmark every American recognizes. The Statue of Liberty is easily identified by its height, stance, and unique blue-green color (Figure 17.16). When this statue was first delivered from France, its appearance was not green. It was brown, the color of its copper "skin. " So how did the Statue of Liberty change colors? The change in appearance was a direct result of corrosion. The copper that is the primary component of the statue slowly underwent oxidation from the air. The oxidation-reduction reactions of copper metal in the environment occur in several steps. Copper metal is oxidized to copper(I) oxide (Cu2O), which is red, and then to copper(II) oxide, which is black. Q: Changes in the color of the statue of liberty owe to oxidation-reduction reactions, or what simpler term? Choices: - copper - oxygen - immersion - corrosion A:
Ans:
corrosion
