Answer:
The cell body of a neuron is called SOMA. The soma or pericarion contains the nucleus surrounded by the cytoplasm; Inside them we find different types of organelles:
-Mitochondria
-A Golgi apparatus
-Smooth endoplasmic reticulum (REL)
-Nissi's body
-Cytoskeleton, formed by neurofibrils.
Answer:
Lysosomes
Explanation:
Tay-sachs disease is a rare Autosomal recessive disease that causes neurodegenerative disorder.
Deficiency of an enzyme Hexosaminidase A results in excessive accumulation of gangliosides (sialic acid containing glycosphingolipids) in the brain and nerve cells.
It is a lysosomal storage disease .Absence of the enzyme Hexosaminidase A ,that breakdowns substance like fats results in accumulation of such substance in the lysosomes.Too much accumulation of fats in the lysosomes destroy the cell.
Answer:
4)
Explanation:
Gametes have one haploid (n) genome, which is half of somatic cells, having one diploid (2n) genome combined through fertilization from two haploid (n) gametes.
In humans, gametes have 23 chromosomes, and somatic cells have 23 homologous pairs, which is 46 chromosomes.
Different species have different numbers, but most follow the same pattern.
Answer:
The correct answer will be option-D
Explanation:
The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.
The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.
Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.
Thus, option-D is the correct answer.
Answer:The answer is D.
Explanation: It's mitosis not reproduction.
