Explanation:
A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original. The earlier in the sequence the deletion or insertion occurs, the more altered the protein. A frameshift mutation is not the same as a single-nucleotide polymorphism in which a nucleotide is replaced, rather than inserted or deleted. A frameshift mutation will in general cause the reading of the codons after the mutation to code for different amino acids. The frameshift mutation will also alter the first stop codon ("UAA", "UGA" or "UAG") encountered in the sequence. The polypeptide being created could be abnormally short or abnormally long, and will most likely not be functional.
Answer:
The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine. Filtered blood leaves the kidney through the renal vein and flows back to the heart.
Pee leaves the kidneys and travels through the ureters to the bladder. The bladder expands as it fills.
Explanation:
Hypogeal germination is when the plant is germinated under the ground. An example of this would be the pea plant.
epigeal germination is the opposite of that. Germination takes place above the ground. normal bean plants have epigeal germination
Answer: D
Explanation:
The lipopolysaccharides are found in the outer membrane of Gram-negative bacteria. Lipopolysaccharide is complex molecule consisting of a lipid and chains of carbohydrates. They are also called endotoxin, they are the major component of the outer cell membrane. Sugars in the polysaccharide chains of endotoxin confer serologic specificity. They lplay a crucial role in bacteria resistance to antibiotics.
Answer:
a.aquatic plants
Explanation:
The energy stored in organic matters, which can be used as fuel for various purposes. This the same energy obtained from the sun that is passed on to each tropic level by the 10% law. This is known as biomass energy.
Biomass is highest at the first trophic level in any food chain. In the aquatic food chain also the highest biomass at the first trophic level which aquatic plants.
Hence option a is correct.
