Answer:
DNA replication is a semiconservative process.
Explanation:
The DNA molecule is made of two chains (or two strands), also called double-stranded (two chains).
There is complementarity of nucleotides or nitrogen bases:
- Thymine with Adenine,
- Guanine with Cytosine.
This DNA molecule is duplicated. For this, locally, we have an opening of these two chains by enzymes. We speak of enzymatic complex. This set of enzymes comes to open both strands of DNA. After opening the two strands, in the nucleus, there are several free nucleotides which bind to the template strand by complementarity.
We had a single molecule of DNA, we then had two. The two chromatids (or the two DNA helices) are therefore sister, because they are strictly identical. We speak of a semi-conservative replication because we keep one of the two matrix strands to copy identically its complementary, thanks to the complementarity of nucleotides or nitrogenous bases.
Answer:
Saliva's normal pH range is between 6.2 and 7.6. It's average is like a 6.7. Saliva keeps a neutral pH balance and doesn't fall below 6.3 in the oral cavity.
Explanation:
I hoped this helped a little bit.
The principal money Mrs Karki deposited in the bank was
= Rs 1339
Simple interest (Si) received = Rs 4,740
Time (t)= 6 years
Rate (r)= 59%
Therefore the principal amount (p) =
where,
Therefore, the principal money Mrs Karki deposited in the bank was = Rs 1339

Answer:
60-70%
Explanation:
Carbohydrate is the most important source of energy needed in preparation for prolonged exercise that consumes energy and requires endurance and strength to combat fatigue.
Carbohydrate is a more efficient fuel than fat as carbohydrates are easily broken down to supply an athlete with glucose as readily available energy, and also glycogen that is stored in the muscles, which are used as a fuel source during exercise. Hence, for prolonged heavy exercise, it is recommended that athletes need high carbohydrate consumption of 60-70 percent of their calories to maintain optimal performance.
