CLEP Biology Practice Exam

Photosynthesis is the correct answer because it is the process by which green plants use sunlight, chlorophyll, and carbon dioxide to produce glucose and oxygen. During photosynthesis, chlorophyll in the plant's cells absorbs light energy, which is then converted into chemical energy. This chemical energy is used to combine carbon dioxide and water to produce glucose, a form of stored energy that plants can use for growth and development. Oxygen is also released as a byproduct of photosynthesis.

The odd one out in this group is "Jaguar" because it is the only animal that is not commonly found in the wild in most parts of the world. Wolves, hyenas, and dogs are all known to exist in various habitats across different continents, whereas jaguars are primarily found in the Americas, specifically in rainforests and swamps.

Abortion is not considered a form of birth control because it involves terminating a pregnancy after conception has occurred. Birth control methods are used to prevent pregnancy from happening in the first place. Withdrawal, the use of condoms, and spermicidal cream are all forms of contraception that aim to prevent fertilization and pregnancy.

Concave glasses are the correct correctional glasses for long-sightedness. Concave lenses are thinner at the center and thicker at the edges, causing light to diverge before entering the eye. This helps to correct the focusing issue of the eye and allows for clear vision at near distances.

The correct answer is "Biotic Factor". Biotic factors are the living components of an ecosystem, including plants, animals, fungi, and microorganisms. These organisms interact with each other and their environment, playing crucial roles in the functioning and balance of the ecosystem. Biotic factors influence the availability of resources, energy flow, and nutrient cycling within the ecosystem. Therefore, the living things in an ecology are considered biotic factors.

The dermis is the layer of skin located between the epidermis and the subcutaneous tissue. It is composed of various structures, including blood capillaries, sweat glands, and hair follicles. However, the epidermis is not part of the dermis. The epidermis is the outermost layer of the skin and is primarily responsible for protecting the body from external factors.

The Femur, commonly referred to as the thigh bone, stands out as the most robust and elongated bone within the human body. Renowned for its strength, the femur not only serves as a crucial structural support for the lower extremities but also plays a pivotal role in facilitating various essential biomechanical functions, making it a key component of the skeletal system.

Behavior is not transferable with genetics because behavior is influenced by a combination of genetic and environmental factors. While certain genetic traits may predispose individuals to certain behaviors, behavior itself is not solely determined by genetics. Environmental factors such as upbringing, experiences, and cultural influences also play a significant role in shaping behavior. Therefore, behavior cannot be solely attributed to genetics and is not transferable through genetic inheritance.

The correct answer is "Breathing in air to break down food substances." Respiration is the process by which organisms obtain energy from food. In humans, this involves breathing in air, which contains oxygen, and using it to break down food molecules through a series of chemical reactions. This process releases energy in the form of ATP, which is used by cells for various functions.

Faeces is not a product of excretion because it is the solid waste material that is formed in the large intestine and eliminated through the rectum. Excretion refers to the process of eliminating waste products from the body, and while gas, urine, and sweat are all waste products that are excreted, faeces is the result of the digestion and absorption of food rather than the elimination of metabolic waste.
