• Overfishing

• Deforestation

• Poaching

• Urbanization

Answer explanation

One major threat to elephant populations caused by human activity is poaching, where elephants are illegally hunted for their tusks and other body parts.

How are elephant cells similar to plant cells?

• Both have chloroplasts

• Both have cell walls

• Both have mitochondria

• Both lack a nucleus

Answer explanation

Elephant cells are similar to plant cells in that both have mitochondria, which are essential for energy production within the cell.

What determines the unique characteristics of an elephant, such as trunk length and tusk size?

• Proteins

• DNA

• Lipids

Answer explanation

DNA determines the unique characteristics of an elephant, such as trunk length and tusk size.

What is one physiological adaptation of elephants that helps them survive in their environment?

• Thick fur for warmth

• Large ears for temperature regulation

• Webbed feet for swimming

• Sharp claws for climbing

Answer explanation

One physiological adaptation of elephants that helps them survive in their environment is their large ears, which aid in temperature regulation.

Which organelle in elephant cells is responsible for producing energy?

• Nucleus

• Mitochondria

• Ribosome

• Golgi apparatus

Answer explanation

In elephant cells, the organelle responsible for producing energy is the mitochondria.

Elephants have a DNA structure similar to other mammals. What is the shape of a DNA molecule?

• Single helix

• Double helix

• Triple helix

Answer explanation

The shape of a DNA molecule is a double helix, consisting of two strands that wind around each other in a twisted ladder-like structure.

Elephants have evolved large ears. What is the primary evolutionary advantage of this feature?

• Better hearing

• Communication

• Temperature regulation

• Defense

Answer explanation

Elephants have evolved large ears primarily for temperature regulation, helping them dissipate excess heat and maintain a stable body temperature.
