Answer:
The nitrogenous bases present in DNA are purine (adenine or guanine) and pyrimidine (cytosine or thymine). Uracil is absent from DNA. Uracil is present as pyrimidine base in ribonucleotides which are components of RNA.
Answer:
A gamete containing an extra chromosome is formed.
Explanation:
Geminal mutations may result in the production of mutant gametes. If such gametes fuse with those from another individual of the opposite sex to form a zygote, the mutation is transmitted to the progeny. A trisomy gamete containing an extra chromosome would transmit the mutation to the offspring after fertilization.
Answer:
If cellular respiration and photosynthesis stops performing their role in carbon cycle all the plants and animals will end up dying. This is because they are dependent on the carbon cycle for survival.
Explanation:
The correct option is (D) the attraction between water molecules.
The attraction between water molecules cause surface tension.
<h3>What causes the water molecules' surface tension?</h3>
- Cohesive interactions between the liquid's molecule's cause the surface tension to develop. The molecules at the center of the liquid are surrounded by other molecules on both sides.
- The net force is zero because molecules are tugging on one another equally in all directions. In contrast to the majority of the liquid, the liquid molecules at the interface only have half as many nearby molecules.
- This results in a net inward pull toward the liquid and a stronger association of the molecule with the molecules on either side of it. The force preventing the surface from breaking is surface tension.
