Platinum and gold is the answer . :)
Answer:
True:
A heat source could be considered a source of pollution.
Explanation:
The reason behind this is that global warming is attributed to the general warming o the planet's temperature without making a specification of a single source or a singular type of origin. It just accounts for warming. One of the major discoveries of this problem was the fast-food chain's contribution to global warming. Saying that the fast-food industry provides a considerable amount of warming to the planet.
Enzymes and substrates are related in two main ways because they frequently interact with each other in many biological processes.
1. Enzymes and substrates are often specific for one another. They have shapes that can be modified to fit into each other which allows them to bind together (induced fit).
2. Together, Enzymes and substrates undergo some transformations as they interact. They interact by forming hydrogen bonds, covalent bonds and what is also called hydrophobic interactions.
The enzyme returns to its original shape and state after the reaction but the substrate is often modified or changed completely into a new, different product.
Answer and Explanation:
In a cell, the smaller the surface area in relation to its volume, the lower the rate of diffusion. The ratio of surface area to volume of an object decreases sharply with increase in its size. The materials move across the cell rapidly because the cell has a larger surface area to volume ratio thus the rate of diffusion of materials is high.
