Bromothymol blue (BMB) is an indicator dye that turns yellow in the presence of acid. When
carbon dioxide is added to the solution, it creates carbonic acid, lowering the pH of the
solution. BMB is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and
yellow when the pH is less than 6
Answer:
The correct answer is - incomplete dominance.
Explanation:
A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.
In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.
Thus, it is the case of incomplete dominance.
Because the chromosomes have to divide basicly and they go to an offspring.
In spermatogenesis,from a single spermatogonia 4 haploid sperms are produced after meiosis (100% efficiency).But in case of oogenesis,from a single oocyte only one is transformed into ovum even after meiotic division(25% efficiency)
Answer:
Question 10: True Question 11: Competition and Variation
Explanation:
Natural Selection is when the animal with the best survival rates gets the right to mate. Every species wants to survive and by letting the animals with the best traits reproduce, it ensures their survival. This, of course, happens naturally.
Competition is to show whose fit and whose not and variation increases the chance of their survival. For example, if a whole species was exactly the same if one died of a disease then all of them would, because they would have the same immune system. But if there is variation, one might be vulnerable to the disease but the other might have protection from it. Meaning it could pass those genes to offspring because it was fit.
Hope this helped :)
