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: 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: Nucleus
Explanation:
Transcription is a process of production of mRNA which occurs in the nucleus of the cell. After transcription, translation which occurs in the cytoplasm.
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: osmosis
Explanation:
Water reabsorption by the renal tubules is harmonally controlled and it is a osmosis mechanism.
Correct Answer: To decrease heat flow
Correct Answer: It is possible to test hypotheses, such as those involving historical events, without conducting experiments.
Explanation:
The correct statement among the given options about the process of scientific inquiry is "It is possible to test hypotheses, such as those involving historical events, without conducting experiments."
Although it is not possible to carry out experiments to test hypotheses about evolutionary relationships between living groups or about the timing of the origin of major evolutionary innovations, such hypotheses can be evaluated by making predictions about the expected findings that would result from these hypotheses. Data can then be collected to test whether these predictions are correct.
Correct Answer: Glucose
Explanation:
Here cellulose, sucrose and glycogen are all the forms of glucose. Hence, glucose includes all the other three given options.
Correct Answer: Iron
Explanation:
Iron reacts with oxygen in the presence of moisture or water to form a red oxide called rust and the reaction involved is called as Redox reaction.
