Answer:
Approximately six
Explanation:
The codon GGU
Single base substitution that will change this codon that codes for glycine to another amino acid includes: a single base substitution in the GGU codon such as GGU- AGU can occur. thus, approximately six single base substitution can take place to change this codon to code for another amino acid. A single base substitution cannot change the codon to a stop codon unless it happens twice or there is more than a single base substitution.
Answer: Option B
Explanation:
The population of moose increased during 1990-1995 because the predators that feed on moose population was low.
The predators that feed on the population of moose are large carnivores which eats them.
This caused increase in the population of moose during 90s as there was a sudden decrease in the population of predators that feed on them.
The chromosomes of offspring are not identical to those of their parents or siblings because <u>genetic information</u> is shuffled during meiosis.
Meiosis can be described as a cell division process by which gamete cells divide. The number of chromosomes is reduced to half in this cell division process.
During the process of meiosis, genetic information is shuffled between non-sister chromatids of the homologous chromosomes. This shuffling process is referred to as crossing over. A new combination of alleles is formed due to the process of crossing over.
It is due to the process of crossing over that the organisms produced are not identical to each other or the parents. Genetic diversity is important in order for populations to survive which is possible through the process of meiosis.

Answer:
Plants have cell walls, mammals have cell membranes.
Answer:
they are not made of the same ingredients
Explanation:
All living things breathe, eat, grow, move, reproduce and have senses. Non living things do not eat, grow, breathe, move and reproduce. They do not have senses.
