The caretaker of a farm feeds hay to the cows to procure milk from them. How much energy will the cows get from the hay?
nikitadnepr [17]

<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.

Predict how results would change if the field were watered daily. A. Nothing would change. B. All the plants would increase in n
iragen [17]

Answer: B

Explanation:

I'm not sure, but I'd say that the best answer choice would be B because most of the plants would grow, and none would die off. The smaller plants would grow, and would grow in, and most if not all of the larger would just continue to grow, if they aren't already full grown.

Hope this helped!

What is the best explanation for the observation that eukaryotes that seem superficially simple can have much larger genomes (in
brilliants [131]

Answer:

Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.

Explanation:

DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.

Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.

Thus, the correct answer is option (b).

Which explanation is most likely the reason for the evolution of a larger brain in humans? The size of the human brain increases
SCORPION-xisa [38]

Across nearly seven million years, the human brain has tripled in size. The most likely the reason for the evolution of a larger brain in humans is that a larger brain allows humans to solve complex problems. Large, complex brains  enable humans to process and store a lot of information and to interact with each other and with their surroundings better. The  brain we now humans have is the largest and most complex of any living primate.
