Answer:
<em>Allele frequency</em>
Explanation:
Allele frequency can be described as the percentage or ratio for the existence of a particular allele in a population. Allele frequency determines which allele is present more abundantly in a population and which allele is not significantly present in the population. The allele frequency determines the genetic diversity which will be present in a population. The alleles which code for traits that make an organism more adaptable to a particular environment will have an increased allele frequency.
It can be because there are some parts around that arent getting water
Ans. (B). Mutated gametes (sex cells) fuse to create offspring.
Genetic mutations or germline mutations can be defined as permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other, when a mutated sperm or mutated oocyte (gametes) get fertilized with other oocyte or sperm.
A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, as single-celled zygote divides and produce all of the cells in that organism.
Thus, the correct answer is option (B).
Answer:
Body temperature
Explanation:
Homeostasis is the a resistance to change due to the body's attempt to maintain constant and stable internal environment. To maintain the body's overall functioning it is very important that homeostasis is maintained at all levels.
Body temperature can be used as homeostasis parameter in the lab. It is important that that the body tries to maintain a constant temperature.
Answer options:
- extraction and observation of DNA
- identification of ribose and deoxyribose
- recognition of RNA as DNA’s messenger
- construction of an accurate DNA model
Answer:
- identification of ribose and deoxyribose
Explanation:
Phoebus Levene was an American biochemist who studied the structure of DNA and RNA. He was able to isolate the sugars (ribose and deoxyribose) from the nucleic acids, which are an important part of their structure.
He also determined how the nucleic acid components combine to form the nucleotides, the basic building blocks of nucleic acids, and how the nucleotides combine in chains to form the polymer.
