solniwko [45]3 years ago
7 0

Answer:

Exposure to chemicals or radiation is an environmental factor that could

influence natural selection and increase genetic  diversity.

Explanation:

There are several factors that could easily influence natural selection and increase genetic  diversity. one such factor could be exposure to chemicals or radiation.

Radiations can alter the genetic code and disrupt the DNA decoupling and coupling process thereby producing altered gene. This altered gene when interact with native parent gene can give rise to mutated offspring. The presence of mutated/altered allele increases the genetic diversity.

How can the Geosphere affect the atmosphere
Zolol [24]
The correct option is C.
The geosphere refers to the solid parts of the earth. All of these parts are affected when a volcanic eruption occur. When volcanic eruption occurs, it contributes to the greenhouse effect in the atmosphere because carbon dioxide which is regarded as a greenhouse gas is released into the atmosphere. Also sulphur dioxide gas is released which results in acid rain.

How do you change dna to rna to amino acids
yanalaym [24]
This can be done through the Transcription and Translation process.

Long story short: DNA -> messenger RNA (mRNA) -> amino acids -> polypeptide chain -> protein

Step 1: Transcription
1) DNA loop is open
2) RNA polymerase (enzyme in nucleus) catalyze reaction of “unzipping” DNA
3) free RNA nucleotides in nucleus will be added to that strand of DNA
4) messenger RNA moves across nuclear membrane to cytoplasm (our nucleus)

Step 2: Translation
1) messenger RNA attaches to ribosome
2) mRNA determines which amino acid to place on protein
3) uses codons (triplet) on mRNA. Codon on mRNA and anticodon on tRNA have to match, which places true amino acid in ribosome, then it detached and finds another amino acid in cytoplasm.
4) “AUG” starts translation, and keeps going until reaching “stop codon”.
5) completed polypeptide chain results to protein being synthesized

Your teacher should explain this process more in depth hopefully

kvasek [131]

Answer:

Hot metal.

Explanation:

Hot metal is the stimulus that allows nervous system and muscular system work together. When the person touch the hot metal, the sensory cells present on the skin sends signals to the central nervous system through sensory neurons. The central nervous system made a decision and order to the muscles of the hand to remove hand from the hot metal or body. These orders are send to the muscles through motor neurons. In this way, both nervous system and muscular system work together.
