From single-celled ancestors, they evolved into a riot of complexity and diversity. An estimated seven million species of animals live on earth today, ranging from tubeworms at the bottom of the ocean to elephants lumbering across the African savanna.
There are two jet streams, a subtropical and a polar-front jet stream.
Answer:
Explanation:
I think it is: acetylcholine (neurotransmitter) - motor neuron - contract
second question: diffusion because of opening of ca2+ channels
The answer is <span>a frameshift deletion at the beginning of the gene.
The frameshift deletion means that due to the deletion, the reading frame will be changed. Because of this, changed mRNA will be synthesized and translated into altered protein. It is known that codon is a triplet (a set of three nucleotides), that code for certain amino acid. The earlier in the sequence the deletion occurs, the protein will be more severely affected.
For example, if codons on RNA are THE BIG BAD DOG and the frameshift deletion happens on the first triplet (earlier in the sequence), the changed sequence will be TEB IGB ADD OG. If </span>the frameshift deletion happens on the third triplet (later in the sequence), <span>the changed sequence will be THE BIG ADD OG.</span> This way, if the<span> frameshift deletion occurs at the beginning of the gene,</span> the more codons will be changed and in turn, they will code different amino acids.
