Which of the following statements accurately describes enzymes?a. Enzymes slow chemical reactions.
b. enzymes increase the activation energy of reaction.
c. Temperature and pH can affect how enzymes Work .
d. Many different types of substrates with different shapes can bind to a single enzyme

Answers

Answer 1
Answer:


The best answer is c - temperature and pH can affect how enzymes work.

Enzymes are active only within a narrow pH range. The most favorable pH , the point where the enzyme is most active is called the optimum pH.  Extremely high or low pH outside the optimum  generally results in complete loss of activity for most enzymes.

Enzymes are also most active at a specific temperature  called optimum temperature. 

Temperatures significantly below the optimum slow down enzyme activity while those significantly above the optimum may denature the enzyme, causing permanent and irreversible damage.

Write “$6,188 for 82 shares of stock” as a unit rate. Round to the nearest hundredth, if necessary. A. $13.25/share B. $69.24/share C. $80.92/share D. $75.46/share

Answers

Answer:

Option D is correct.

Unit rate = $75.46/ share

Explanation:

Unit rate defined as the rate are expressed as a quantity 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.

Given the statement: $6,188 for 82 shares of stock.

⇒Number of share = 82

\text{Unit rate per share} = \frac{\text{Cost}}{\text{Number of share}}

Substitute the given values we get;

\text{Unit rate per share} = (6,188)/(82) = \$75.4634146

Therefore, the unit rate (nearest to hundredth place) is, $75.46/ share
$6,188/82=75.4634146 so if you round that to the nearest hundredth you get $75.46(C)

What is an ecosystem?

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By the decomposition of  the dead plants and animals by  action of microbes nutrients are released back in to the soil.
