B.

Large scales on the back of a lizard

C.

Feeding during the hottest part of the day

D.

A small kidney to conserve water

Correct answer is A

Aestivation: Certain animals enter a state of estivation, which is similar to hibernation but occurs in response to hot and dry conditions. They become inactive, conserve energy, and reduce water loss during the hottest parts of the day or during extended periods of high temperatures.

63.

Which of the following processes is involved in the reproduction of developing organisms?

A.

Budding

B.

Germination

C.

Fertilization

D.

Pollination

Correct answer is C

64.

Which of the following is an example of an abiotic ecological factor?

A.

Temperature

B.

Competition

C.

Predation

D.

Symbiosis

Correct answer is A

Abiotic ecological factors are non-living factors that influence an ecosystem. They include physical and chemical factors such as temperature, sunlight, water availability, soil composition, and air quality.

65.

What is the tissue responsible for transporting water and minerals from the roots to the rest of the plant?

A.

Xylem

B.

Epidermis

C.

Parenchyma

D.

Phloem

Correct answer is A

The tissue responsible for transporting water and minerals from the roots to the rest of the plant is called xylem. Xylem is a complex tissue composed of specialized cells, such as tracheids and vessel elements, which form long, interconnected tubes. These tubes facilitate the upward movement of water and minerals through the plant. Xylem also provides mechanical support to the plant.
