Answer:
Reduces heat lost to the water
Explanation:
In some birds such as the geese, to reduce the amount of energy cost when regulation their temperature, some morphological and behavioural has been used to maintain the rate of heat gain and loss. For uninsulated parts of the birds's body such as the legs, there is the presence to countercurrent head exchange between wherein the arteries and veins in the legs lie in close contact with each other in other to retain heat as these uninstalled regions are potential areas of heat loss since they are uninsulated unlike insulated parts (parts covered with feathers). Constriction of the arteries and veins will ensure blood flow to the feet of the geese at a low temperature.
The answer is New York and Virginia had not ratified it.
New York and Virginia didn't ratify the Constitution until 1789.
Answer:
Biotic means living so all biotic factors rely on each other to survive
Answer:
Layer D
Explanation:
Layer D would be the oldest form of undisturbed rock. This would mean that since it is the oldest, it will be <em>least</em> similar to the present day form of that organism.
Most proteins in living organisms are composed of 40 amino acid residues in total, and nine of those are crucial for human health.
Which majority of amino acids make up proteins in living things?
- Only twenty different amino acids, each with a distinct side chain, make up proteins. Different chemistries can be found in the side chains of amino acids. The majority of amino acids contain side chains that are nonpolar.
- There are nine essential amino acids:
- tryptophan
- valine
- isoleucine
- leucine
- lysine
- methionine
- phenylalanine
- threonine
- methionine
What Constitutes Proteins?
- Amino acids are the basic units of proteins. They are tiny chemical compounds with an alpha (central) carbon coupled to an amino group, a carboxylic acid group, hydrogens, and a changeable element known as a side chain.
- A protein is made up of a lengthy chain of amino acids that are connected by peptide bonds. The biological process that links the carboxyl unit of one amino acid towards the amino group of a nearby amino acid results in the extraction of a water molecule, forming peptide bonds. The main structure of a protein is thought to be its linear amino acid sequence.
