Explanation:
Answer: 37 chromosomes.
Explanation: As is typical of mammals, llamas are diploid organisms, meaning that the number of chromosomes in each of their somatic cells is exactly twice of that found in the gametes (the so-called haploid number, referred to as "n"). If a particular species has 74 chromosomes in its somatic cells, we should expect to find 74/2=37 chromosomes in each gamete.
Answer:
true
Explanation:
Coal is a non-renewable energy source because it takes millions of years to form.
A small change in a persons DNA can cause any number of mutations that may be completely harmless or fatal depending on where the mutation (change) occurs in ones DNA.
Correct answer: B). Cells spend the most time in interphase, where they grow and their DNA replicates.
The cell spends its most of the time in the interphase, during this phase of growth, cell continues to grow and carry out its metabolic activities which are necessary for regular growth and maintenance.
During this phase of the cell cycle, a lot of protein is synthesized in order to double its size. The important changes that occur in this phase include DNA duplication and division of chloroplast and mitochondria.
Hence, the correct answer would be option B.
