Correct Answer: Meiosis
Explanation:
In humans all reproduction is sexual. It involves joining together haploid gamete cells from each parent with half the normal number of chromosomes to make a new cell containing both parents' genetic material. This is a diploid zygote. The cells from each parent that combine to form the zygote are called gametes.
Meiosis produces haploid gametes from a diploid parental cell.
Correct Answer: Insulin
Correct Answer: It generates testable hypotheses, is supported by a large body of evidence, and is broad in scope.
Explanation:
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. Scientific theories are not ever proved in the sense of being proved to be 100% correct.
Examples of some scientific theories are ::
Evolution, gravity, atomic theory, the germ theory of disease, relativity, quantum theory, electromagnetic theory, layered Earth theory, etc...
Correct Answer: All of the above
Explanation:
Yes, we know that water is a universal solvent.
Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization.
Water is a polar molecule that has a high level of polarity and attraction to ions and other polar molecules.
Hence, all the above given options are the properties of water.
Correct Answer: Solution
Explanation:
A homogeneous mixture is also called as solution.
The term "solution" is more frequently used when a homogeneous mixture is a liquid, although it is sometimes used if the homogeneous mixture is a gas.
Another name for a solid homogeneous mixture of metals is an alloy.
Correct Answer: Hypoxemia
Explanation:
Oxygen deficiency or decreased oxygen levels in the blood is a condition known as Hypoxemia.
Hypercapnia means High carbon dioxide levels in the blood.
Correct Answer: unrelated to any realistic, known source
Explanation:
Free floating anxiety is also known as Generalised Anxiety Disorder in which the individual may be unable to identify specific triggers for the anxiety.
Correct Answer: Aeolus
Correct Answer: osmosis
Explanation:
Water reabsorption by the renal tubules is harmonally controlled and it is a osmosis mechanism.
Correct Answer: To decrease heat flow
