Answer:
See the answer below
Explanation:
<em>Both transcription and DNA replication produce nucleic acids which are polymers of (C, G, A, and T or U). Both processes depend on an enzyme which adds one nucleotide at a time. </em>
<em>To determine which nucleotide is added next, both transcription and DNA replication use the nucleotide sequence in a </em><em>template DNA</em><em> strand and the </em><em>base pairing </em><em>rules.</em>
Transcription is a process through which RNA is synthesized using a DNA template. An enzyme known as RNA polymerase adds nucleotide bases to grow the RNA strand.
Replication is a process during which DNA makes a copy of itself. The double helix unwinds and each strand is used as a template to make a new strand. An enzyme known as DNA polymerase adds nucleotide bases to grow the new strands.
<u>In both transcription and replication process, the nucleotide sequence of the template DNA strand determines the which nucleotide will be added to the new RNA and DNA strands being synthesized according to the base pairing rule. Purine bases always pair with pyrimidine bases and more specifically, cytosine always pair with guanine while adenine always pair with thymine (uracil in RNA).</u>
Answer:
b) 1,000
Explanation:
In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.
Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.
Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.
= 10/100 × 10,000 = 1000 units of energy.
The notable
hardness of bone is attributed to the presence of inorganic hydroxyapatites.
Due to the calcium salts deposited in it, resulting to the hardness. The
abnormal hardness of bone, which allows it
to resist the compression.
The answer to this question is Paradoxical sleep.
Paradoxical sleep is the stage of sleep where in the person’s muscles are
relaxed and this is the stage that is called a dreaming sleep. In this stage of
sleep the person is in deep sleep state.
