Sediment is the answer from the knowledge i have and from what i found
Answer:
The correct answer is "True".
Explanation:
Over-the-counter (OTC) medicines are a type of drugs that are sold directly to the consumer without needing a doctor's prescription. OTC medicines that contain decongestants and antihistamines can raise blood pressure and heart rate, therefore its use for children must be monitored. The FDA reports that children, particularly under the age of 2, could suffer life-threatening side effects from taking these medicines, including: convulsions, rapid heart rates and death.
BLINK protein speeds up stomatal movements in response to light fluctuations resulting in improved plant growth and water use.
Plants can't move, so their “blinking” helps protect them from burning or bleaching when they are in bright sun.
I'm not sure if the first part is right, but I do know the second part is.
Answer:
4. c. Deletion/ frameshift mutation
5. a. Tyr Tyr Asp Ser Gly
6. A frameshift occurred which altered the identity of the amino acids following the initiator 6. methionine, but not the length of protein Q.
Explanation:
4)
A single base pair at the first position of the Arg codon i.e. CGA has been deleted. Due to the deletion, the reading frame has shifted one nucleotide backwards, altering the amino acid sequence of the protein.
5)
The genomic DNA sequence is 5'-ATG ATA CTA AGG CCC-3'. Therefore, the complementary mRNA will be 5'-UAC UAU GAU UCC GGG-3'. According to the genetic code, this mRNA sequence encodes the following amino acid sequence: Tyr Tyr Asp Ser Gly
6)
The wild type DNA sequence is:
5'-ACUGUAAUGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
The mutant i.e. mRNA with the added G will be
5'
ACUGUAAUGGGAGUCAGAUGAUGCAUUAAGGAGAAAUUGAAAUAAA-3'
This is a single base pair insertion and frameshift mutation that shifts the reading frame one base pair forwards. The codon that was originally GAG coding for glutamic acid (Glu) gets converted to GGA that codes for glycine. Therefore, the amino acid sequence has been altered but the polypeptide chain will still have 13 amino acids.
Answer:
2.Less than 73% of the populations would have only one allele present.
Explanation:
The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.
Using a larger breeding population would not be expected to alter the outcome of the experiment.
