Please make sure that you post a complete question. This is the part missing:
- <span>How might this offset transcription or translation errors?-
The existence of several codons that code for the same amino acid ensure that even when a mistake in the processes of transcribing the sequence from DNA to mRNA or translational errors, there is still a significant chance of correct amino acid being added to the protein.</span>
Answer:
p = 0.34
Explanation:
The green allele is recessive, meaning two copies of q (qq) are required to be green. Conversely, animals that are either pp or pq will be blue.
If 44 organisms are green, that means 44 are qq.
For genotype frequencies, the equation is:
homozygous dominant genotype + heterozygous + homozygous recessive = 100%
Which is denoted as
p² + 2pq + q² = 1
We know that q² = 44/100 = 0.44
To work out q, we can do
= 0.66
For allele frequencies, the total must add up to 100%, so
p + q =1
We know that q= 0.66
So p = 0.34, because 0.66 + 0.34 = 1
The correct answer is: b. conscious neural control
Neural control of digestive tract is unconscious achieved via the autonomic nervous system.
Local nervous system of the digestive system is called the enteric or intrinsic nervous system. The major components of this nervous system are two networks or plexuses of neurons:
• The myenteric plexus – controls digestive tract motility
• The submucous plexus - regulates gastrointestinal blood flow and controls epithelial cell function.
Answer:
Photosynthesis is the process by which plants make their own food in the presence of sunlight by utilizing carbon-dioxide and water and produces oxygen and energy.
The process of photosynthesis has two types of reactions: light-dependent reactions and light-independent reactions.
The light-dependent reactions occur in the thylakoid membranes of chloroplasts in which plants use light energy to form ATP and the reduced electron carrier NADPH.
In this reaction, photosystem II (P700) absorbs lights energy and passed it to reaction center. this energy is then is transferred to photosystem I (P680), that pump an electron to a high energy level. The high-energy electron then travel to an electron transport chain and releases energy. this released energy pump H+ ions into the thylakoid interior from the stroma and build a gradient H+ ions move through gradient and they pass through ATP synthase resulting in the formation of ATP.
The higher energy electron as moves into an electron transport chain, the electron is passed to NADP+ to form NADPH.
