Humans have reduced environmental stability drastically due to our contributions to climate change through carbon dioxide and other greenhouse gas emissions. we have changed the weather patterns, increased global temperatures and caused air and plastic pollution as well as many others. the environment has changed and put animals and plants at risk of extinction because of heating of the earth, loss of habitat, etc
The glandular swelling is found on the back of the earthworm and is called C.litellum.
An earthworm is tube shaped and it belongs to the Annelida phylum. It is usually found in the soil, where it contribute to the level of fertility of the soil by feeding on the dead organic matter and by aerating the soil. Earthworms lack internal skeletons and they are hermaphrodites.
The rank from most likely to least likely of the one-base point mutations will be: (B) 4, 3, 2, 1
4. deletion mutation within the first exon of the gene.
3. substitution mutation at the second position of a codon in an exon.
2. substitution mutation at the third position of a codon in an exon.
1. insertion mutation deep within an intron.
Insertion mutation can affect the structure but only when present in the axon. Deletion mutation can change the whole reading frame pf the m-nucleotide sequence.
Substitutions can at maximum change one amino acid in the reading frame as one amino acid will be replaced by another. And if the substitutions is at the third place of the codon triplet, chances are that the amino might not even change as one amino acid are coded by more than pone codons.

The answer would be letter B.
Answer:A bat has a much more flexible wing structure. It is very much like a human arm and hand, except it has a thin membrane of skin (called the patagium) extending between the "hand" and the body, and between each finger bone. Bats can move the wing like a hand, essentially "swimming" through the air.
