These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.
Explanation:
Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. And the parts of the brain involved in motor control lose cells over time.
Researchers found that the brain's response time begins to decline at age 24. The descent is a slow, but nonetheless, steady one.
Good Afternoon,
I believe what you are speaking of may be the following. There is the equator is the center of the earth. Then, their is, on top of the equator, The Tropic of Cancer which passes through Cuba. On the bottom of the Equator, is the Tropic of Capricorn which passes through the Amazon Forest in South America. I hope that i have helped and good luck!
Thank you,
Darian D.
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.
