1.
Animals are _____, they cannot make their own food.
Correct Answer
B. HeteortropHy
Explanation
Animals are classified as heterotrophs because they cannot produce their own food through processes like photosynthesis. Instead, they rely on consuming other organisms or organic matter to obtain the nutrients and energy they need for survival. Heterotrophs obtain their food by either hunting, scavenging, or feeding on plants or other animals. This is in contrast to autotrophs, which are capable of producing their own food through photosynthesis or chemosynthesis.
2.
_____ is the evolutionary adaptation of a cell for a particular function. Ribosomes produce proteins.
Correct Answer
A. Specialization
Explanation
Specialization refers to the evolutionary adaptation of a cell for a particular function. In this case, ribosomes are specialized organelles within a cell that are responsible for protein synthesis. They are specifically adapted to carry out this function efficiently. Therefore, specialization is the correct answer in relation to the given statement.
3.
Which primary tissue layer give rise to outer layer of skin; nervous system and sense organs such as eyes?
Correct Answer
A. Ectoderm
Explanation
The ectoderm is the primary tissue layer that gives rise to the outer layer of skin, as well as the nervous system and sense organs such as the eyes.
4.
A term used to describe an animal's shape, symmetry, and internal organization is called a(n)_____.
Correct Answer
B. Body plan
Explanation
The term "body plan" refers to the overall organization and structure of an animal's body, including its shape, symmetry, and internal organization. It encompasses various aspects such as the arrangement of body parts, the presence or absence of certain structures, and the overall symmetry of the animal. This term is used to describe the blueprint or design of an animal's body, which determines its overall form and function.
5.
Animals with cephalic end, or heads, are often active and very mobile.
Correct Answer
A. True
Explanation
Animals with a cephalic end or heads are often active and mobile because having a head allows them to have specialized sense organs, such as eyes and ears, which help them navigate their environment and locate food. Additionally, having a head allows for better coordination and control of movements, enabling them to respond quickly to stimuli and engage in various activities. Therefore, it is true that animals with a cephalic end or heads are often active and mobile.
6.
What type of body symmetry does the animal in the image below exhibit?
Correct Answer
B. Bilateral Symmetry
Explanation
The animal in the image exhibits bilateral symmetry. This means that it can be divided into two equal halves along a single plane, resulting in a mirror image. Bilateral symmetry is commonly seen in animals that have a distinct front and back, as well as a left and right side.
7.
What type of body symmetry does the animal in the image below exhibit?
Correct Answer
B. Bilateral Symmetry
Explanation
The animal in the image exhibits bilateral symmetry. This means that its body can be divided into two equal halves along a single plane, resulting in a mirror image on each side. Bilateral symmetry is commonly found in animals that have a distinct front and back, such as humans, and allows for efficient movement and specialization of body parts.
8.
What type of body symmetry does the art work in the image below exhibit?
Correct Answer
A. Radial Symmetry
Explanation
The art work in the image below exhibits radial symmetry. Radial symmetry is a type of body symmetry where body parts are arranged around a central axis, like the spokes of a wheel. In the image, the design elements are arranged symmetrically around a central point, creating a balanced and harmonious composition. This type of symmetry is commonly found in nature, such as in flowers or starfish, and is often used in art and design to create visually pleasing and balanced compositions.
9.
What type of body symmetry does the animal in the image below exhibit?
Correct Answer
B. Bilateral Symmetry
Explanation
The animal in the image exhibits bilateral symmetry. Bilateral symmetry is a type of body symmetry where the organism can be divided into two equal halves along a vertical plane. This means that the left and right sides of the animal's body are mirror images of each other. In the image, we can see that the animal has a distinct left and right side that are symmetrical.
