Answer:
The correct answer is - 1:2:1 for black : blue : white chicken.
Explanation:
We know that color of the feather is a trait of the chicken that shows the codominance type of inheritance pattern where both forms of the trait are dominant and make a mix of the forms. In this case, blue is heterozygous BW and black BB and white is WW, then crossed between BW with BW
gametes: B, W and B, W
Punnett
B W
B BB BW
W BW WW
thus, the phenotypic ration is - 1 black : 2 blue : 1 white

Explanation:
<span>Interstitial fibrosis and glomeruli tubular atrophy are pathological effects of hypertension on kidneys. This is especially as a result of hyalinization that results in sclerosis to the glomeruli which may ultimately lead to kidney failure if unmanaged. The hyaline accumulate in the nephron tubules resulting in protein in urine. The plaque build up in the kidneys, as a result, causes glomerular ischemia </span>
When scientists measure, they use the metric system.
Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
