Answer:
The transitional epithelial tissue is perfect for bladder function because it has the ability to stretch.
When the bladder is empty, the cells have a cuboidal shape. When the bladder is full, the cells have a flat shape.
Explanation:
Transitional epithelial tissue is the tissue that makes up the entire bladder and some organs of the urinary system. This tissue has the ability to allow the organs covered by it to have the ability to change shape and size, because this tissue allows these organs to stretch, so it is the perfect tissue to cover the bladder.
As we know, the bladder is the organ responsible for storing urine. When it is filled with urine, the bladder stretches, at that moment, the bladder cells are compressed and assume a flat, stretched shape. When it is empty, the bladder shrinks in size, becoming "wilted", at that moment, its cells assume a cuboidal shape.
Explanation:
The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.
The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.
When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.
On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.
Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find
9 SSWW: 3 SSww: 3 ssWW : 1 ssww
This is the phenotypic ratio of the offsprings.
The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.
The answer is D, because the others isn't what the picture is given.
Answer:
FIRST ONE
Explanation:
Reproduction. Pink salmon in their native range have a strict two year life cycle, thus odd and even-year populations do not interbreed. In the state of Washington, Pink salmon runs occur on odd years. Adult pink salmon enter spawning streams from the ocean, usually returning to the stream where they originated.
Heredity is the passing of physical or mental traits from generation to generation.
