B is the answer. Sharks need salt water to survive to make the breathing and blood pump through their bodies.
Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
The answer is DDDDDDDDDi hope help you!
Answer:
White-tailed deer are adapting to the environment with their specific color. This way the predators can’t see them. If sometimes the danger is very close, they can freeze and camouflage so that no one can see that they are actually on the spot.
Explanation:
These animals are living in different areas, but the best area for them is a place with dense grass where they can eat. They have many ways of camouflaging in nature, so they are used to avoiding danger. This is why they live longer.
Answer: 2 They involve a different number of parents.
3 Only one process involves sperm and eggs.
5 Only one process involves cell division.
Explanation:
The sexual and asexual reproduction are the two modes of reproduction through which the organisms produce offspring and lead their generations. The asexual reproduction takes place in simple organisms whereas the sexual reproduction takes place in complex organisms.
The following are the differences between asexual and sexual reproduction:
2 They involve a different number of parents.: In asexual reproduction only single parent is involved which produces a large number of offspring whereas in sexual reproduction two parents are involved which produces limited number of offspring.
3 Only one process involves sperm and eggs.: In sexual reproduction the fusion of the male and female gametes is required for production of offspring.
5 Only one process involves cell division.: Asexual reproduction occurs through cell division that is a single parent cell get split into two daughter cells.
The DNA is identical in offspring produced by asexual reproduction but not similar in offspring produced by sexual reproduction as two parents are involved and segregation of chromosomes takes place during gamete formation.
Meiosis does not occur in asexual reproduction. This occurs in sexual reproduction during gamete formation.
