Te answer would be <span>C. "Some mutations can be contagious, like infections.</span>" Mutations happen regularly and are often so subtle that we do not notice them on a daily basis. Some of them, however, can indeed cause harm.
Answer: a triple bond and a single bond
Explanation:
DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
Explanation:
Physical weathering is the disintegration of rocks into smaller chunks in nature.
Water is one of the agents that causes physical weathering.
- during periods of low temperature especially the summer, water usually collects within rock cavities.
- When temperature drops, the water freezes and expands.
- Periodic freezing and thawing of ice leads to physical weathering.
- Also, in tropical regions, alternate wetting and drying of rocks occur.
- When a rock is wet, it absorbs more water and it volume expands.
- Drying occurs and it loses the water.
- This continuous process leaves cracks in rock.
