The digestive system breaks down food, the respiratory system takes in oxygen, and the cardiovascular system delivers the oxygen and food to the cells.
Answer:
It results in the production of new combinations of alleles due to which offspring can have different characters than both the parents.
In meiosis, the genes are randomly segregated and the alleles of genes are independently assorted to produce haploid gametes.
When the gametes of male and female fuses, they form the zygote with a unique or new combination of alleles as compared to that of parents.
It increases the genetic variations in the population.
B) the cattle would have to convert the cellulose structure into starch
Answer:
For every turn of the citric acid cycle, one molecule of <u>ATP</u>, four molecules of <u>NADH </u>and one <u>FADH₂</u> molecule is produced.
Explanation:
"For each turn of the cycle, a molecule equivalent to ATP is produced, and 5 pairs of high-energy electrons are captured by 5 carrier molecules: 4 NADH molecules and 1 FADH2. FAD and FADH2 are molecules similar to NAD+ and NADH, respectively"
Hope this helps
Answer:
C) The amount of A is always equivalent to T, and C to G
Explanation:
Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A), Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
