What does a plant cell have that an animal cell wall does not?
- A.
Double Nuclei
- B.
Cell Membrane
- C.
Ribosomes
- D.
Cellulose Wall
Correct Answer
D. Cellulose WallExplanation
A plant cell has a cellulose wall, which provides rigidity and support to the cell. This wall is made up of cellulose fibers and is located outside the cell membrane. On the other hand, an animal cell does not have a cell wall. Instead, it is surrounded by a flexible cell membrane that regulates the movement of substances in and out of the cell. The presence of a cellulose wall is a characteristic feature of plant cells that distinguishes them from animal cells.Rate this question:

Which group of animals has their legs on the sides of their bodies?
- A.
Amphibians
- B.
Mammals
- C.
Fish
- D.
Birds
Correct Answer
A. AmphibiansExplanation
Amphibians have their legs on the sides of their bodies. This allows them to move effectively both on land and in water. Having their legs positioned on the sides helps amphibians to navigate through various terrains and swim efficiently. This adaptation is particularly useful for amphibians as they often live in diverse habitats and need to be able to move and hunt in different environments.Rate this question:

Scientists believe that the earliest birds are descended from what animal group?
- A.
Mammals
- B.
Cycads
- C.
Reptiles
- D.
Snails
Correct Answer
C. ReptilesExplanation
Birds are believed to have evolved from reptiles. This is supported by fossil evidence, which shows that birds share many anatomical features with reptiles, such as scales on their legs and beaks. Additionally, birds and reptiles both lay eggs and have similar skeletal structures. This suggests a common ancestry between the two groups, with reptiles being the most likely group from which birds evolved.Rate this question:

Through what organ, apart from lungs or gills, do amphibians take in oxygen from the air?
- A.
Mouth
- B.
Nostril
- C.
Skin
- D.
Feet
Correct Answer
C. SkinExplanation
Amphibians have a unique ability to absorb oxygen through their skin. Their skin is thin and moist, allowing oxygen to pass through it and into their bloodstream. This is especially important for amphibians like frogs and salamanders, as they often live in aquatic environments with low oxygen levels. The skin acts as an additional respiratory organ, supplementing the oxygen intake from the lungs or gills. This adaptation allows amphibians to effectively breathe through their skin, making it a crucial organ for their survival.Rate this question:

Which type of energy has a low frequency?
- A.
Ray Ban
- B.
Radio waves
- C.
Gamma Ray
- D.

Correct Answer
B. Radio wavesExplanation
Radio waves have a low frequency compared to other types of energy. Frequency refers to the number of waves that pass a certain point in a given amount of time. Since radio waves have a low frequency, it means that they have a longer wavelength and lower energy. This is why radio waves are commonly used for communication purposes, such as radio and television broadcasting, as they can travel long distances without losing their strength.Rate this question:

Photons
Correct Answer
D. PhotonsExplanation
Photons are minute particles that make up waves of electromagnetic energy. They are the fundamental particles of light and other forms of electromagnetic radiation. Photons have no mass and travel at the speed of light. They carry energy and momentum and interact with matter through various processes such as absorption, emission, and scattering.Rate this question:

What must an object have to exert gravitational force?
- A.
Color
- B.
Mass
- C.
