mRNA Codon chart Using the above chart, name the amino acid that is coded for by a strand of DNA: CCA O Alanine O Arginine Isoleucine O Proline
Answer:
[tex]\boxed {\boxed {\sf Proline}}[/tex]
Explanation:
We are given a codon (set of three nucleotides) and asked to find the amino acid it codes for.
There are a few types of charts that can be used, for example, the circular one attached starts in the middle and goes outward. Follow the sequence of the three letters from the center.
Another chart attached can be used. For this, we must find the intersection of the three letters. Located the 1st letter on the left, the 2nd on the top, and the 3rd on the right.
Based on both charts, proline is the correct amino acid.

Answer:
i hope this helps
Explanation:
Effectors include muscles and glands - that produce a specific response to a detected stimulus. For example: a muscle contracting to move an arm. muscle squeezing saliva from the salivary gland.

Explanation:
Paul and Jennifer university are stadyingIf a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.
How does movement of the legs affect the gills of crabs?
Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

In 6 sentences, Cellular & Physical Comparison. Tell me the differences between plants and animals.
Answer:
Plants have either no or very basic ability to sense. Animals have a much more highly developed sensory and nervous system. Animals give off carbon dioxide which plants need to make food and take in oxygen which they need to breathe. Plants cells have cell walls and other structures differ from those of animals.

Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.
