There are four types. Muscle, Epithelial, Connective, and nervous.
Answer:
Humans affect the environment in positive and negative ways. Cutting down trees and littering have a negative effect on animals and plants. Protecting endangered species and cleaning lakes and seas has a positive effect on the environment.
Answer:
The strands of the hybrid helix are less complementary than the original helix.
Explanation:
Complementary DNA strands are bonded to each other through hydrogen bonding. The nitrogenous base adenine (A) forms 2 hydrogen bonds with thymine (T). Guanine forms 3 hydrogen bonds with cytosine. Due to the presence of 3 hydrogen bonds, GC rich regions of DNA or RNA are more strongly bonded.
Therefore, if the two strands will be less complementary or contain more AT rich regions, the double helix will denature or melt at a lower temperature.
The answer is 100 days. At day 100 the population of the organism began to stop growing, which means it has reached its carrying capacity.
