Peroxiosome is a membrane bound cellular organelle which plays many important roles. Detoxification of poisons and toxic compound is one of the most vital role performed by it.
If it gets ruptured in the cell,it will lead to the accumulation of toxicity which woiuld be a dangerous situation for the cell.
Answer:
The correct answer is option d.
Explanation:
In a fish, the heart comprises two chambers, a ventricle, and an atrium. The deoxygenated blood comes through the body, moves into the atrium and then into the ventricle, from where it is pushed towards the body through the gills.
The pumping of the blood via the heart takes place via the capillary beds of the gills and via the tissues’ capillary beds. When the blood come in the capillary beds of the gills it gets slow down. It moves gradually via its path to the tissues and requires skeletal muscular activity to help the blood to mediate towards the heart again. Thus, a fish is dependent upon the physical effort for blood to get circulated again to the heart.
The heart of an amphibian-like the frog exhibits three chambers, two atria and one ventricle. In the process of circulation, that is, in the ventricle, the oxygenated and the deoxygenated blood gets mixed prior to being impelled out of the heart. However, amphibians possess lower metabolisms and thus, they need less oxygen. The requirement of a lesser amount of oxygen puts less pressure on the heart to provide blood with high oxygen. Thus, a heart comprising three chambers is suitable for the requirements of amphibians who could absorb oxygen via their moist skin.
The correct answer is silent mutation .
There are sequences present in the body where a point mutation occurs but the protein formed is still the same
Answer:
The correct option is<em> C) Organism A is a plant because the cells have chloroplast.</em>
Explanation:
As we can see, the organism in the slide A is multi-cellular and has chloroplast present in its cells. This means that the specimen is most likely taken from a plant. Hence, A is the correct option.
Other options, like option B, is false because nucleus can be present in animal and plant cells both. Option D is false because the cell cannot be differentiated on the basis of cytoplasm as every organism possesses a cytoplasm in which the organelles float.
