1.) what is the optimal pH for pepsin? where is pepsin found?
guajiro [1.7K]

Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0

The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2.  The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8.  around 7

Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

Which of the following statements correctly describes the relationship between biodiversity and sustainability? (1 point)
laila [671]

The statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.

<h3>What do you mean by Biodiversity?</h3>

Biodiversity may be defined as the sum total of all the living organisms living in a particular ecosystem.

As the number of species increases, biodiversity also increases because both are directly proportional to one another.

While the species enhancement negatively impacts the sustainability of the environment.

Therefore, the statement that correctly describes the relationship between biodiversity and sustainability is, biodiversity increases while sustainability decreases with an increase in the number of species in an ecosystem.

PIT_PIT [208]

Proteins, nucleic acids, and carbohydrates are grouped by common structural features found within their group. lipids can be grouped based on their high solubility in nonpolar solvents, and their preponderance of nonpolar groups.

Non-polar solvents cannot dissolve a polar compounds since no opposite charge exist, and the polar compound is not attracted. It is this becuase of absence of partial charge that also makes these molecules non-polar. Some of examples of non-polar solvents include benzene, hexane, pentane, toluene, etc.

Higher the solubility of a compound is that the larger the amount of the compound which can dissolve in a solution.

Explain how hyperpolarisation occurs in an axon cell (4 marks)​
shusha [124]

Answer: Hyperpolarization occur when ion channels in the membrane open or close, altering the ability of particular types of ions to enter or exit the cell. For example: The opening of channels that let positive ions flow out of the cell (or negative ions flow in) can cause hyperpolarization.

Brainliest pls if it is correct!
