<span>Waste products such as poop, diarrhea, and carbon dioxide (look in the respiratory system) must be removed. If they are allowed to accumulate they cause poisoning which slows down vital chemical reactions. Which can cause many problems to develop.</span><span />

Able to find more food means more likely to survive - survival of the fittest i.e. natural selection.</span>
The answer is letter D. Substrate; Active Site The enzyme
itself remains unchanged. It advise the
active place of an enzyme is frequently reshaped by interactions with the
substrate until the substrate is completely bound and the chemical reaction
occurs, the lock and key model.
The correct answer is upwelling from equatorial to Polar Regions results in bringing oxygen from the epipelagic zone to deeper oceanic zones.
It is a process in which the wind mediated motion of nutrient-rich, dense, and cooler water is moved towards the surface substituting the nutrient depleted and warmer surface water. The epipelagic zone refers to the upper layer of the ocean, which is abundant in oxygen and gets the majority of the sunlight for the procedure of photosynthesis. The upwelling of water from the equatorial to the polar region brings oxygen.
