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.

Which of the following
Pachacha [2.7K]

Phosphate groups of the nucleotides in the diagram are marked with W.

Option C.

<h3><u>Explanation:</u></h3>

DNA is a macro molecule which is formed of polymerization of deoxyribonucleotides. Four types of deoxyribonucleotides are present which are adenosine, guanosine, thymidine and cytosine triphosphate. These nucleotides are polymerized based on the genetic setup.

The phosphate groups attached with the sugar molecule are actually polymerized with the o glycosidic bond. That's marked with the letter W. These phosphate molecules are attached with the sugar molecules which actually are attached with the nitrogen bases. They in total forms a nucleotide, hence the whole DNA. X in the diagram are nitrogen bases and the Y are the hydrogen bonds between the complementary nitrogen bases

Which molecule is responsible for the wide diversity of life on earth?
Elden [556K]
A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.

Reptile [31]
The precambrian era makes up about 90% of the earths history, but there was little to no living organisms at the time other than microscopic ones. The first eukaryotes were found in the cambrian period after the precambrian period, not only that but at the end of the precambrian era in the Proterozoic era there was a mass extinction of about 70-80% of all living organisms
