Answer:
A. Left ventricle; systemic
Explanation:
The ventricles are located on the posterior end of the heart beneath their corresponding atrium. The right ventricle helps to receives deoxygenated blood from the right atria and pumps it through the pulmonary vein and into pulmonary circulation, then transported into for gas exchange via the lungs.
The left ventricle receives oxygenated blood from the left atria and pumps it through the aorta into systemic circulation in order to supply the tissues of the body with oxygen.
The walls of the ventricles are the thickest and strongest. This is because the amount of work on the left ventricles, which pump blood throughout the body and lungs, is much greater than the pressure generated by the atria to fill the ventricles.
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain
<h2>
ANSWER:</h2>
16 protons and 19 neutrons
<h2>
EXPLANATION:</h2>
The atomic number or proton number of a chemical element is the number of protons located in the nucleus of an atom. It is same as the charge number of the nucleus
Sulfur possesses an atomic number of 16, so it owns 16 protons.
protons + neutrons = atomic weight,
35-16=19. So sulfur has 16 protons and 19 neutrons
Answer:
Interphase
Explanation:
Interphase is the G1, or gap 1, phase in which the new cell grows and carries out its functions in the body; the S, or synthesis, phase when the chromosomes replicate; and the G2, or gap 2, phase, when the cell grows further and prepares to divide.
The two main components of the extracellular matrix are Elastin and Collagen.
The extracellular matrix is an intricate macromolecular network that is found in the extracellular space. The matrix is composed of polysaccharides and very diverse proteins, locally secreted and assembled forming a complex network that surrounds the cells. The matrix is highly developed in connective tissue and its derivatives. The extracellular matrix is formed mainly by proteins, glycosaminoglycans,proteoglycans and glycoproteins, organized in diverse networks that constitute the different tissues. <em>The most abundant proteins are collagen and elastin.</em>
Collagen is a family of very abundant proteins in the body of animals. Collagen molecules can represent 25 to 30 % of all body proteins. Its main mission in the tissues is to form a framework that supports the tissues and that resists the forces of mechanical tension.
The elastin molecules are very close to each other through links between the regions rich in the amino acid lysine. It is an abundant protein in may extracellular matrices and appears as a component of the so called elastic fibers, which are onsoluble aggregates of proteins.
