<span>D.Oxygen- rich blood is carried in the aorta from the left ventricle to the body
</span>Superior and inferior vena cava enters the right atrium which is pumped by the tricuspid valve to the right ventricle and to the pulmonary valve to the pulmonary artery then to the lungs from the lungs back thru the pulmonary veins entering the left atrium pumped by the mitral valve to the left ventricle to the aortic valve to the aorta.
<span>The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.</span>
As materials move from higher to lower concentration diffusion is occurring.
Answer:
<em>One pair of wings.</em>
Explanation:
The presence of one pair of wing is the best conclusion which supports Andre's observation. It is because, arthropods refers to invertebrate creatures without a spine. They have sectioned bodies and an exoskeleton, a skeleton outside of their bodies.
The name originates from another component they share—jointed members, for example, wings, legs, and mouth parts. In Greek, arthro signifies joint, and unit signifies foot or leg.
All arthropods have an outer skeleton-an exoskeleton. It has two body segments. with a pair of wings and four pairs of legs for walking.
Answer:The answer is the second option from the top: Anoxic waters create a harsh environment that does not support marine life.
Explanation: Looking at the table, the amount of dissolved oxygen water (which enables marine species to breathe underwater) at station 138 is 0.02mg/liter compared to 1.5mg/liter, much lower than at station 137. Anoxic means "lacking oxygen", which sharks need to survive. So a lack of oxygen in a particular region will limit the number of sharks able to survive or live in that region.
Answer:
