The lysine amino acid will provide a positive charge to the active site. If this mutation changed all of the lysine amino acids to aspartic acid, it will produce an enzyme having a negative charge.
<h3>Mutations and amino acids</h3>
A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an organism.
A mutation that alters the active site of an enzyme will invariably affect its catalytic activity.
A mutation that involves a change in lysine (positive) to aspartic acid (negative) will produce a protein having a net negative charge.

Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.
Answer:
C. They can grow to larger populations more quickly
Explanation:
Bacteria are the <u>key entities</u> of <u>biogeochemical cycle</u>s (Nitrogen, Carbon, Oxygen, etc.) on Earth. The strength of these cycles is typically achieved when they can multiply faster in a relatively <u>short time period</u>. If all bacteria on Earth start reproducing via sexual means only, then many of the biogeochemical cycles would take forever, thus <u>generating nutrients at a slower rate</u>. Since higher organisms (e.g. eukaryotes) depend on the abundant supply of nutrients, the overall life on Earth would be compromised to a larger extent in the absence of sufficient nutrients supply. Thus, it is <u>beneficial for all forms of life that bacteria reproduce mainly via asexual means</u>.
PS: A simple bacterium can produce millions of copies in 24 hours period.
Answer: Photosynthesis
Explanation: Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.
Answer:
Explanation:
Satellite cells are small glia that surround neurons' sensory ganglia in the ANS. These resemble the astrocytes of the CNS and assist in regulating the external chemical environment. PNS satellite glia are very sensitive to injury and may exacerbate pathological pain.
