Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. ... When a dominant allele is completely dominant over another allele, the other allele is known as recessive.
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. ... A heterozygous individual will appear the same as a homozygous dominant individual. This means that an organisms with two dominant alleles appear the same as an organism with only one functioning allele.
Answer:
distal convoluted tubule
Explanation:
This is the region of the nephron downstream the macula densa ,which extends the to convulence of the collecting duct.Due to response to mineralocoticoid aldosterone they can be categorised as Distal Convoluted 1 and Distal convoluted 2. This steroid hormones is responsible for homeostatic control of hyperkalemia.
The DCT cells are simple cuboidal epithelium.The stained or pointed part of the image represented this possess this shape,they are therefore portion of DCT. Besides the stained cells are located above the glomerulus ()in the cortex as indicated,therefore they can not be the proximal which must be below the glomerulus, based on the shape ascending and descending loop of Henle (despite located in the cortex too).
The functions of the DCT is in the absorption and secretions of ions(majorly ca+,Na+ and chloride ions.By secreting hydrogen and reabsorbing HC03 ions ,the pH of the urine is maintained.
Hey there! :D
When we are talking about gametes, we can use a punnet square, or in this case, common knowledge. If two of the alleles for one phenotype are the same, we can infer there will only be two variations of the genotype. (because there are two dominant SS genes) We already know that "D" must be the answer. Firstly, there will be one allele for each gene, so there will always be an "S" and a "T" no "SS" or "tt" (when talking about gametes). That leaves us with B and D but there is no recessive "s" in the original genotype, so the answer must be "D".
I hope this helps!
