<span>Answer: a. Citizens over the age of 65 use social media primarily to follow the activities of their families. </span>
<span>More than half of the citizens over 65 say that they have a social media account. They read other postings but post information about one-fifth as often as they read posts. Most of their feeds consist of posts by relatives. From this passage, we can logically say that Citizens over the age of 65 know how to use the social media and they use it primarily to follow the activities of their families. </span>
A.Osmosis occurs through a semi permeable membrane. Diffusion occurs in permeable membrane.
3 nucleotides code for a single amino acid. This group of 3 is known as a codon. If you are coding for two amino acids, you would need two codons, 3 nucleotides each, for a total of 6 nucleotides.
Answer:
The the above statements are true about out groups.
Explanation:
a. Out groups called as the more related organism that determine the evolution of the in group traits.
Plesiomorphy means the ancestral character that determines the phylogenetic evolution of an individual.For example, presence of spinal column is a plesiomorphic character of mammals that are present in fish, amphibia,reptiles, birds etc.
b. In groups are diverge from the out group but the out groups are used as a point to compare with the in groups as it is essential to determine the evolution of a trait in a phylogeny.
c. Autapomorphic traits contain distinctive characters that is unique and found in a particular taxa but not found in a any other out group taxa.
d.Out groups are less evolved as they contain ancestral features and during evolution they are replaced by advance characters that are presently in in group traits.Out group study is required to study the evolutionary relationship of the in group trait.
