Exosphere is in the top 600-800km exosphere has a very low amount of gases almost like in outer space.
Termosphere, 80-600km absorbs gamma rays uv rays and rays that damage our healt also know as ionosphere, is the hottest one.
Mesosphere, 50-80km, the temperature here reaches -140 Celsius shooting stars are formed here
Stratosphere, 12-50km produces the mayor part of the atmospheric ozone, some army planes reach this later
Troposphere, thats the source of the mayor part of the gases here in the atmosphere.
Please please if I was useful please mark this as brainlyest
Answer:
People throw their trash and pollution into the fresh water and make it not as fresh or safe to the animals as much as it could be.
Explanation:
Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.
Essential amino acids refer to the eight amino acids the adult body needs, which they cannot be synthesized correctly or at all.
The essential amino acids must be obtained from food such as proteins (meats, seafood, milk, eggs, etc).
Answer:
<h2>A) Yes, 12 mu</h2><h2>B) AaWw</h2><h2>C) 0.25%</h2><h2 />
Explanation:
As given,
Allele A for blue anthocynin.
aa for yellow kernel;
at second locus;
W produce smooth kernel,
ww for wrinkled kernel;
Parents as given are: AaWw and aaww
Progeny are:
blue smooth ( AaWw)= 1447;
blue wrinkle (Aaww)= 169;
yellow smooth (aaWw)= 186;
yellow wirnked (aaww)= 1510
a)
Recombinant progeny are 169+ 186= 355
non- recombinant progeny are = 1447+ 1510= 2957
so recombination frequency (RF)= 346/2957×100= 12.0054%
So a and w are linked genes.
They are 12 mu far away from each other.
b) Blue smooth parent= AaWw.
c) Aaww crossed with aaWw
progeny are= AaWw, Aaww, aaWw, aaww,
They all are produced in same proportion =0.25% or 1/4.
