Mutated gene

A mistake by cellular machinery, or damage from an environmental agent such as radiation may produce a mutated gene which is a permanently altered segment of dna.  

A gene mutation is a perpetual change in the DNA sequence that forms a gene which makes the sequence different from what is present in most people. Gene mutations can be classified into; hereditary mutation (changes inherited from parents) and somatic mutation (changes caused by environmental factors such as ultraviolet radiation from the sun).

The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Re
Nutka1998 [239]

Answer:

The correct answer is D. Reduced levels of circulating estrogens.

Explanation:

Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

Snapdragons are a type of flower. When red snapdragons are crossed with white snapdragons the resulting flowers are all pink. A
Akimi4 [234]

There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.

The genotypes and phenotypes that we will employ to address this issue are as follows:

RR - Red

RW - Pink

WW -  White

They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross

RW x RW

The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)

This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.
