Answer:
a.) rate of population growth
Explanation:
The population growth rate determines how a population will be distributed in a region. Populations with a high growth rate need to occupy more spaces, in addition to needing to consume a greater volume of natural resources. As the population grows, the distribution in the region becomes more intense, the opposite also happens. When the population growth rate indicates that the population is decreasing it means that this population will need less space and therefore, its geographic distribution will be smaller, as well as its impact on the region.
Here is the complete sentence with the correct answer; The Coriolis effect causes surface ocean current to sink toward the ocean floor, then rise again to the surface. The correct answer is D.
Answer:
Hemoglobin is an iron-containing protein present in the blood that functions for transportation of oxygen to different body cells..
Each hemoglobin molecule have tetrahedral structure consist of four heme groups surrounded by a globin group. Heme, is composed of porphyrin (ringlike organic structure) which is attched to an iron atom. There are four iron atoms in each molecule of hemoglobin that binds with four oxygen atoms and globin carry two linked pair of polypeptide chain.
The oxygen reversibly binds with the polypeptide chain and the process called oxygenation.
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.
