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.

Aliun [14]

Answer: There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.

The energy left at this level is 10% of the energy that primary consumers have.

Hence, Producers will have 475,650 kilocalories

Primary consumers will have 475,65 kilocalories

Secondary consumers will have 4756.5 kilocalories

Without bacteria in the environment
timurjin [86]

Answer:

e. All of the choices are correct.

Explanation:

Bacteria are present almost everywhere on Earth. Many bacteria like cyanobacteria play an important role in fixing the atmospheric carbon in the form of an organic molecule. These organic molecules then used to gain energy.

Many nitrogen-fixing bacteria like Rhizobium,  Azotobacter, etc plays an important role in providing nitrogen to plants which is important for their growth. Many bacteria decompose organic matter into simpler form and recycle the nutrients present in them.  

So bacteria like <em>Pseudomonas putida</em> decompose waste and clean the environment, therefore, they also help in bioremediation. So the correct answer is e. All of the choices are correct.

AnnyKZ [126]

ABO blood group determination is a example of multiple Alleles.

<h3>What is Multiple Alleles?</h3>

Multiple alleles refer to a type of non-Mendelian inheritance pattern that comprises of more than the normal two typical alleles that is dorminant and recessive alleles that usually code for a certain characteristic in a species.

Examples of multiple Alleles is the genes of ABO blood group determination.

Therefore, ABO blood group determination is a example of multiple Alleles.
