Answer:
(A) Benthic- Benthic refers to the lowest or the bottom zone of the water body such as seas, and oceans. The organisms existing under such extreme pressure conditions are commonly known as benthic organisms. For example, corals and bivalves.
(B) Pelagic- Pelagic refers to the upper top portion of a water body, covering the open sea areas. The organisms existing in this region include dolphins and sharks.
(C) Sessile- Sessile refers to the property where an organism is stationary and cannot move freely from one place to another. These are known as sessile organisms such as coral polyps, Mussels.
(B) Mobile- refers to the property by which an organism can move freely in any direction it wants. For example, fishes, dolphins.
(E) Evisceration- It is a specific type of property where organisms can eject their internal organs in order to protect themselves from predators. for example, Sea cucumbers.
(F) Chitin- Chitin is a hard shell that is present in various organisms, forming its exoskeleton, for defense purposes. For example, arthropods.
Answer:
All green algae produce large, stationary eggs
Explanation:
The research on the evolution of land plants has shown that the plants have evolved from the green algae especially the "Charophytes" which grows in on the rocks attached to the rocks on the seashore.
The evidence that plants evolved from the green algae was supported by the:
1. The storage material of both the plants and algae is the same that is starch
2. both the algae and plants have the sporophytic and gametophytic life cycle
3. Both the plants and algae possess the same type of the photosynthetic pigments like chlorophyll a,b,c,d and others.
4. Both have a cell wall made of cellulose
But the green algae produce the stationary eggs does not support the hypothesis as the plants not necessary produce the stationary eggs.
Thus, the selected option is correct.
Answer:
Anabolic steroids are related to testosterone, the major male hormone. Abusing the hormone can lead to physical and psychological side effects. Problems include breast development and hair loss among men, and facial hair growth, menstrual problems, and a deepened voice in women.
Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.
