Answer:
Of course, you could scan their driver’s license or look for signs of facial wrinkles and gray hair. But, as researchers just found in a new study, you also could get pretty close to the answer by doing a blood test.
Woman looking at herself in mirror That may seem surprising. But in a recent study in Nature Medicine, an NIH-funded research team was able to gauge a person’s age quite reliably by analyzing a blood sample for levels of a few hundred proteins. The results offer important new insights into what happens as we age.
Explanation:
For example, the team suggests that the biological aging process isn’t steady and appears to accelerate periodically — with the greatest bursts coming, on average, around ages 34, 60, and 78
Answer:
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.
Explanation:
Most important is that it can secrete proteins<span>. </span>Protein<span> is </span>made<span> by rough ER, chemically modified and </span>packaged<span> in the membrane and then vesicles move into the plasma membrane, fuse with it, and then release the contents</span>inside<span>.</span><span>,and budded of from the Golgi, or </span>made<span> by the ER.</span>
<span>In general, Eukaryotic cells are a fair bit larger than Prokaryotic cells (if you look at them under the microscope, you can generally see details inside Eukaryotic cells, whereas Prokaryotes are just tiny dots).
</span>Prokaryotic cells are 0.2-2 uM (micrometers or 10^-6)
Eukaryotic cells are 10-100 uM
Give or take, eukaryotic cells are 50-100 times bigger <span>than prokaryotic cells.</span>
So, when our eyes see light, our brain gets signals that make us feel awake. But when its dark, the signals make us feel tired. ... When your body releases more melatonin, you feel more tired. The human body starts releasing melatonin in the evening around bedtime and continues throughout the night.
I hope that answers your question
