Answer:
yes.
Explanation:
I believe that some form of life exists outside of our planet. the galaxy is gigantic and ever-expanding. there's a very low chance that with every planet out there, there's no other life form. Now, humans have depicted aliens in many ways. green with black eyes, brown like E.T.... some speak English and some speak a language we cannot understand. I'm not sure if the life forms that are out there would be as developed as we imagine, but anything is possible with an ever-expanding universe. I think the closest we'll ever get to finding an "alien" is a couple of cells that are "alive"
Answer:
d. it diffuses into mitochondria to be broken down to generate ATP
Explanation:
When enough oxygen is available in the muscle cells, pyruvate produced by glycolysis enters the mitochondrial matrix. Once inside the mitochondria, pyruvate is decarboxylated into acetyl CoA. The reaction is catalyzed by the enzyme complex pyruvate dehydrogenase. Acetyl CoA then enters a sequence of reactions called Kreb's cycle and is broken down into CO2 and H2O. The energy released during these reactions is stored in the form of NADH and FADH2.
The NADH and FADH2 are oxidized by giving their electrons to O2 via electron transport chain. During this oxidation, the proton concentration gradient is generated across the inner mitochondrial membrane which in turn drives the process of ATP synthesis.
Answer: Temperature control
Explanation:
Arterio-venous anastomoses (AVAs) are direct connections between small arteries and small veins. In humans they are numerous in the glabrous skin of the hands and feet.
They are very significant in body temperature control. These temperature control are under the dual control of the central nervous system and the local thermal influence. While the arteriovenous anastomoses control the skin temperature through volume changes in the superficial venous bed, the arterioles and capillaries operate by generalized dilatation which results both in increased temperature and in redness of the skin.
Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell. Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system<span> are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons</span>
The pair of terms used to describe the location of the nose
when compared to the location of the eyes are medial and
inferior.
<h3>What is Location?</h3>
Location refers to the exact position of a particular object or
organism. In humans, location of different parts of the body
varies.
The location of the nose is medial to the eyes which means it is
found in the mid-line region of the eyes. The nose is also
inferior to the eyes as it is found in the lower region of where
the eye is located.
