Answer:

DNA is a long polymer with deoxyriboses and phosphate backbone. Having four different nitrogenous bases: adenine, guanine, cytosine and thymine. RNA is a polymer with a ribose and phosphate backbone. Four different nitrogenous bases: adenine, guanine, cytosine, and uracil.

dna deoxyribonucleic acid

RNA - ribonucleic acid

1. The difference between DNA and RNA. The composition of DNA includes deoxyribonucleotides, the composition of RNA - ribonucleotides.

2. Nitrogen bases in the DNA molecule - thymine, adenine, cytosine, guanine; instead of thymine, uracil is involved in RNA.

3.DNA is a matrix for transcription, it stores genetic information. RNA is involved in protein synthesis.

4. DNA has a double helix; RNA is single.

5. DNA is in the nucleus, plastids, mitochondria; RNA - is formed in the cytoplasm, in the ribosomes, in the nucleus, its own RNA is in plastids and mitochondria.d mitochondria.

Less than 0.1% of the enegery in a food chain generally makes it from the sun to quaternary consumers

Harlamova29_29 [7]

Generally, 10% of total available energy is transferred to the next trophic level in any food chain. Rest about 90 % of the stored chemical energy is lost as heat, a by-product of respiration. Let’s assume a 10% transfer rate, starting from producer (100%), primary consumer (10% ), secondary consumer 1%) and tertiary consumer have (0.1%). Therefore, quaternary consumers will have less than 0.1% of energy. Thus, statement is true.

How does a phosphate ion enter a root hair cell

MrRa [10]

Answer:

The root hair cells have carrier proteins in their cell membranes. These pick up the mineral ions and move them across the membrane into the cell against the concentration gradient . ... Because active transport moves ions against the concentration gradient into the root hair cells, energy is needed.

Juli2301 [7.4K]

Let the Total Number of Nests the Group found in the Season be : N

Given : 40% of the Total Nests the Group found in the Season = 28

$\mathsf{\implies 40\% \;of\;Total\;Nests(N) = 28}$
