Answer:
1. The bases are on the <u>interior</u> of the double helix.
2. They are arranged<u> neatly stacked</u>.
3. The phosphate groups are on the <u>exterior</u> of the DNA molecule.
4. The sugar groups on the <u>exterior</u> of the DNA molecule.
Explanation:
DNA is made up of basic chemical components called nucleotides. These basic components include a phosphate group, a sugar group and one of four types of alternative nitrogenous bases. To form a strand of DNA, the nucleotides unite to form chains, alternating with the phosphate and sugar groups.
The four types of nitrogenous bases found in nucleotides are: adenine (A), thymine (T), guanine (G), and cytosine (C). The order, or sequence, of these bases determines which biological instructions are contained in a strand of DNA, being within the strands already mentioned.
Answer:
In physics, a region in which each point is affected by a force. The strength of a field, or the forces in a particular region, can be represented by field lines; the closer the lines, the stronger the forces in that part of the field. See also electromagnetic field.
Answer:
Average mass of 6 apple = 1 kg
Explanation:
Given:
Average mass of 5 dozen apple = 10 kg
Find:
Average mass of 6 apple
Computation:
Average mass of 6 apple = [Average mass of 1 apple] x [6 apple]
Average mass of 6 apple = [10/(12 x 5)] x [6]
Average mass of 6 apple = 1 kg
Answer:
wind and solar are continuously renewable and fossil fuels take millions of years to form
Explanation:
Answer:
The answer to the question is
The specific heat capacity of the alloy = 1.77 J/(g·°C)
Explanation:
To solve this, we list out the given variables thus
Mass of alloy = 45 g
Initial temperature of the alloy = 25 °C
Final temperature of the alloy = 37 °C
Heat absorbed by the alloy = 956 J
Thus we have
ΔH = m·c·(T₂ - T₁) where ΔH = heat absorbed by the alloy = 956 J, c = specific heat capacity of the alloy and T₁ = Initial temperature of the alloy = 25 °C , T₂ = Final temperature of the alloy = 37 °C and m = mass of the alloy = 45 g
∴ 956 J = 45 × C × (37 - 25) = 540 g·°C×c or
c = 956 J/(540 g·°C) = 1.77 J/(g·°C)
The specific heat capacity of the alloy is 1.77 J/(g·°C)
