Answer:
involves injecting the body with specific medication
Explanation:
Vaccination is a versatile and effective methodology for preventing diseases caused by exposure to harmful bacterial and viral infectious agents. Literally, vaccination refers to the administration of medical preparations that help the body to produce immunity against infectious diseases. Vaccines are used to prevent outbreaks caused by infectious diseases. Even under optimal conditions, vaccination is not always effective in preventing disease transmission, because the immune system of each organism may react in a different manner to the same vaccination (even to the same dose). However, vaccination is always encouraged to prevent the spread of infectious diseases. Although there are many vaccines that target age groups, there are others that can be applied to different ages.
A) Thylakoid
B) Lumen
C) Granum
D) Stroma
Medicine is that branch of science that helps us to know a human body and treat it in the right way to stay healthy as long as possible. So there are different factors which intrigue a person to chose medicine as their career of choice.
<h3><u>Explanation:</u></h3>
Medicine practically deals with knowledge about different disabilities as well as diseases that can attack a person to disturb his normal way of life. And for knowing the diseases, the medical practitioner needs to the normal functions of human body too. This fact attracts many person who are keen to know which mechanisms are going inside their body without even their knowledge.
Medicine also deals with different chemicals and compounds that are actually helpful in curing a disease. Thus, helping a person who is suffering from so much of pain because of a disease is so satisfying. There are many doctors who actually help different poor people who can't afford a good medical treatment. So medicine as a career is full of knowledge and experience, so worth taking as well.
Answer:
The water soluble hormones affect the target cells with least amount of interaction.
Explanation:
Hormones are the chemical messengers. These are the substances secreted by the endocrine glands. The hormones are secreted directly into the bloodstream and are carried to the target cells within the blood only.
Based on their structure, hormones are water-soluble or lipid-soluble. The lipid-soluble hormones are steroid hormones and thyroid hormones. These hormones can easily pass through the lipid bilayer of the cell membrane of the target cell. Therefore, the lipid-soluble hormones have intracellular receptors that are present in either cytoplasm or the nucleus of the target cells.
On the other hand, the water-soluble hormones can not pass through the lipid bilayer of the target cells. Therefore, these hormones have extracellular receptors on the surface of the target cells. Binding of the water-soluble hormones to their cell surface receptors triggers the production of the intracellular second messengers that finally carry the signal to the target protein or any other target molecule.
<u>Therefore, a water-soluble hormone exhibits the least amount of interaction with the target cell. Amine hormones such as epinephrine and melatonin, peptide hormones such as oxytocin are some examples of the water-soluble hormones. </u>
Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.
