<span>Lactase enzymes oftentimes come into contact with body temperature entities - 37 C. Ultimately, the enzyme's activity gradually increases with temperature up until about body temperature. Optimum pH for this enzyme is 6. These values provide efficient life of the lactase enzyme.</span>
<span>The answer is autosomes.
</span>In
a human diploid somatic cell (2n), there are 22 chromosomes
present in two copies and 1 pair of sex chromosomes. This means
there are 23 pairs of chromosomes - 22 pairs of autosomes and 1
pair of sex chromosomes. <span>There are in total 46 chromosomes (23 pairs
in 2 copies: 23 × 2 = 46).</span>
Answer:
A
Explanation:
Homeostasis' main job is to keep your body balanced, typically with variable factors such as temperature or enzyme amounts. Your heart rate increases to keep your blood pressure steady while you exercise. This way, you can have a relatively balanced blood pressure as you exhilarate yourself.
Answer: Purine
Explanation:
A purine is a nitrogenous base found in nucleic acids, and contains a 6-membered pyrimidine ring fused to the 5-membered imidazole ring. The most common examples of purine bases are adenine and guanine.
Thus, the nitrogen base pictured is adenine, and the nucleotide considered is a purine
