<u>Answer</u>: C) 10%.

<u>Explanation</u>:

  • The cow will get only 10% energy from the hay as the transfer of energy from a lower to a higher trophic level follows the ten percent law.
  • According to the ten percent law of energy transfer, only 10 percent of the total energy gets transferred to the next trophic level in a food chain.
  • For example, if the hay had 100 joules of energy, the cow will get only 10% of 100 J i.e 10 J energy.
  • The reason why only ten percent energy is transferred is because the rest is lost in the form of heat in the atmosphere.

Answer:

a prezygotic barrier

Explanation:

Both wild tigers and lions are said to be reproductively isolated.

Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.

The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.

Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.

<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>

Why is damage to the heart more serious than damage to the liver ?
Katena32 [7]

Answer:

Heart failure can rob your liver of the blood it needs to work. The fluid buildup that comes with it puts extra pressure on the portal vein, which brings blood to your liver. This can scar the organ to the point where it doesn't work as well as it should.

Don't confuse respiration with breathing. Respiration releases energy, while breathing

What is a telomere? What happens to telomeres each time DNA is replicated? How do cells prevent this from occurring?
vredina [299]
Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase. 
Hope this helps! :)
