It helps with population and reproduction.
Answer:
The type of microscope depends upon the type of sample created.
For observing a sample just to check out its presence of any substance, you can use a simple microscope, and to observe a sample by its morphological features with varying objective lens, you can use compound microscope. To study deep details of the sample, a microscope of high magnifying power like electron microscope can be used.
Answer:
The pulmonary artery carries deoxygenated blood (blood whose oxygen content is relatively low) from the right ventricle to the lungs. The blood here passes through capillaries to alveoli and becomes oxygenated (as part of the process of respiration).
Answer:
The production of peptides linking aminoacids through peptidic bonds
Explanation:
Chemically, peptides are synthesized by condensation where the carboxyl group of one amino acid is linked to the amino group of the other amino acid. The most common way to make a chemical peptide synthesis is linking first the carboxyl end of one amino acid to the amino group, not in the other direction. The opposite reaction, starting from the amino end and linking to the carboxyl end, is made in biosynthesis made by living organisms.
Blue colors dominate the visible light output of very hot stars (with much additional radiation in the ultraviolet). On the other hand, cool stars emit most of their visible light energy at red wavelengths (with more radiation coming off in the infrared).
