Answer:
With respect to genetic information, it is true that a gene is a section of DNA and is found on a chromosome in the cell's nucleus.
Explanation:
DNA contains all the genetic information that determines the morphological and functional characteristics of living beings.
The structure of DNA contains specific sequences of 4 nitrogenous bases, whose extension constitutes the coded genetic information. A chromosome is formed by a DNA molecule, and the<u> </u><u>genes</u><u> contained in the chromosome locus are sequences of nucleotides coming from fragments of that same DNA</u>.
All the genetic information —DNA, chromosomes and genes— is located in the cell nucleus.
Answer:
Any thing or organism that regulates the size of a population of another organism is known as a limiting factor
Explanation:
Organism that regulates the size of a population of another organism is known as a limiting factor which helps to curtail such population. A limiting factor helps in leveraging population and there are factors used to regulate such population, the factors include; predator, parasites, among others
The chromosomes in the sex cells would be half the chromosomes in the body cells; so since each body cell has 40 <span>chromosomes and half of that is 20, there's your answer. It's B. 20</span>
The correct option is 3.
Enzymes are biological catalysts which speed up the rate of biochemical reactions inside the cells. Enzymes are very specific in action and they require specific conditions called optimum conditions for them to function optimally.
When the optimum conditions are not met, an enzyme's activity will be lowered or totally stopped.
Conditions that affect the optimum activity of an enzyme include: temperature, pH level and regulatory activity of regulatory enzymes and hormones.
