Glycolysis evolved very early in ancestors that are common to all the domains of life.
This is because the site of glycolysis is cytoplasm which is present in both prokaryotes as well as eukaryotes.
As prokaryotes are the early ancestors of all domains of life therefore it is also considered that glycolysis is evolved very early.
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.
we know automatically that glucose and pyruvate are wrong answers due to the fact that glucose is sugar and that pyruvate is a type of acid. this just leaves us with ADP and ATP now ADP and ATP are very close answers, since ADP is what makes ATP, but an electron transport change usually involves the transfer of electrons well if we look at their chemical formulas, we can see that ATP has more 1 more oxygen than ADP, and this kind of chain usually adds additional oxygen which gives us ATP as our answer.
The above mentioned process is called as <u>Anaerobic respiration
</u>
<u>Explanation:</u>
All organisms need oxygen to produce energy but in some prokaryotes and eukaryotes they lack the presence of oxygen in their environment. Hence they have adapted a strategy called anaerobic respiration to break down the inorganic molecules to produce energy.
They use carbon dioxide and release methane as the by product. The process of glycolosis helps. All types of fermentation happens anaerobically here. It helps down to break down the fuels and produce energy. This energy is utilized for their life function.
Answer:
The independent assortment of chromosomes is a result of the independent division of chromosomes into separate gametes. Then, crossing over takes place where genes on each chromosome are rearranged. The Law of Independent Assortment discusses the random genetic inheritance from both parents.
