Explanation

There are indeed two main types of metabolic reactions:

1. Anabolic reactions (building molecules, requiring energy)
2. Catabolic reactions (breaking down molecules, releasing energy)

Explanation

In the four-kingdom classification, Kingdom Metaphyta (also known as Plantae) includes:

• Angiosperm (flowering plants)
• Gymnosperm (conifers and related plants)
• Bryophyta (mosses)

Algae are classified under Kingdom Protista.

Explanation

• Medicine involves the diagnosis and treatment of diseases.
  
• Surgery is a branch of medicine focused on operative procedures.
• Both fields are crucial in the overall treatment and management of diseases.

Explanation

Changes in pH can cause enzymes to denature, losing their native structure and activity.

This is because enzymes are highly specific to their optimal pH range.

Changes in pH can disrupt the delicate balance of charges and hydrogen bonds that maintain the enzyme's active structure.

Explanation

As temperature increases, the rate of reaction initially increases due to the increased kinetic energy of the molecules.

It allowing them to overcome the activation energy barrier and react more quickly.

Explanation

Endangered species are animals, plants, or fungi that are at risk of becoming extinct in the near future.

They are threatened by various factors, such as habitat loss, pollution, climate change, overhunting, and human activities.

Explanation

Scientific names of organisms, also known as binomial nomenclature, should be printed in italics.

This is a universal convention in scientific writing to distinguish the scientific name from the rest of the text.

Explanation

Scientific reasoning involves both inductive and deductive approaches:

• Inductive reasoning moves from specific observations to general conclusions (specific → general).
• Deductive reasoning moves from general principles to specific conclusions (general → specific).
