Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. Hope I’ve helped ;)
Answer: systemic veins and pulmonary arteries; pulmonary veins and systemic arteries
Explanation:
Based on what we have learned so far about the cardiovascular and respiratory systems, blood pH should be lower in the <u>systemic veins and pulmonary arteries</u> compared to the <u>pulmonary veins and systemic arteries</u>.
The right answer is B.
Mutations are not always unfavorable, they are often "indifferent" as to the survival of the cells or the individual.
Mutations are the primary source of variation in the genetic material underlying the evolution of living things. They can have a beneficial effect for the species.
Answer:
<em>I stopped to think for a moment, and realized </em><em>chemical energy</em><em> is found in food. Then, I thought about how the other day when I saw lightning, that is an example of </em><em>electric energy</em><em>. Then I thought about how when throw a ball, that is a form of </em><em>kinetic energy</em><em>. The other day, when I was hammering a nail into a piece of wood, that was a form of </em><em>mechanical energy</em><em>. An example of </em><em>nuclear energy</em><em> would be the nuclear power plant by our house. Before my book fell off my table, this is an example of </em><em>potential energy</em><em>. The energy from the sun is an example of </em><em>radiant energy</em><em>. Volcanoes and earthquakes around the world are an example of </em><em>seismic energy</em><em>. </em><em>Sound energy</em><em> would be the balloon that I popped the other day. </em><em>Thermal energy</em><em> would be the heat I feel from the heater.</em>
Halophiles are extremophiles that thrive in environments with very high concentrations of salt. <span>Halophiles prevent this loss of water by increasing the internal osmolarity of the cell by accumulating </span>osmoprotectants<span> or by the selective uptake of potassium ions. Hope this helps.</span>
