Answer:
C) Most fungi get their nutrients by ingesting small pieces of other living organisms.
Explanation:
Most fungi are saprotroph, it is, they obtain nutrients by decomposing non-living organic matter -i.e. dead plant or animal matter- and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.
A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).
Answer:
Option (B).
Explanation:
Heart is the main pumping organ of the body. The human heart is divided into four chambers that are right atria, right ventricles, left atria and left ventricles.
The left and right ventricles can easily be distinguished on the basis of their thickness. The right ventricle is less thicker than left ventricle. The thickness of right ventricle is 9mm whereas the thickness of left ventricle is around 40mm.
Thus, the correct answer is option (B).
The two adaptations of endo parasites:
- Endoparasites (a parasite that lives in the internal organs or tissues of its host) produce some compounds of anti-enzymes which defuse or inactivate the host's digestive enzymes.
- Endoparasites maintain their osmotic concentration equivalent to or significantly lower than the host cell for easy absorption of host water and nutrients.
There are three main classes of parasites involve:
- Protozoa include Plasmodium, the single-celled organism. A protozoa inside the host can only replicate, or split.
- Helminths parasites are worms.
- Ectoparasites: These are living on, not in their hosts.
