Biology: Body Systems Test Review

Explanation
Xylem and phloem are both components of a plant's vascular system. The vascular system is responsible for the transportation of water, nutrients, and sugars throughout the plant. Xylem is responsible for the upward movement of water and minerals from the roots to the rest of the plant, while phloem is responsible for the downward movement of sugars and other organic compounds from the leaves to other parts of the plant. Therefore, the correct answer is vascular.

Explanation
Plants absorb water through their roots, which are specially adapted to take in water and nutrients from the soil. The roots have root hairs that increase their surface area, allowing for more efficient absorption of water. Water then travels up the plant through specialized tissues called xylem, which transport water and nutrients to the rest of the plant. Leaves also play a role in water absorption, but their main function is to facilitate gas exchange through tiny openings called stomata. Therefore, the correct answer is "roots only."

Explanation
Osmosis is the process by which water molecules move across a semipermeable membrane, such as the cell membrane, from an area of lower solute concentration to an area of higher solute concentration. In the case of root cells, water enters the cells through osmosis and is then transported to all parts of the plant, providing it with the necessary hydration for various physiological processes. Transpiration is the process by which water is lost from the plant through the stomata, while mitosis is a cell division process unrelated to water transport.

Explanation
The skeletal system works with the muscular system to produce movement. The skeletal system provides the framework and support for the muscles to attach to, allowing them to contract and create movement. Without the skeletal system, the muscles would not have anything to pull against, and movement would not be possible. Therefore, the skeletal system and the muscular system work together to produce movement.

Explanation
A deficiency in vitamin K would lead to problems with blood failing to clot. Vitamin K plays a crucial role in the production of clotting factors in the liver, which are necessary for the blood to clot properly. Without enough vitamin K, the blood would not be able to form clots effectively, leading to excessive bleeding and difficulty in stopping bleeding.

Explanation
The correct answer is xylem and phloem. Xylem and phloem are the two types of vascular tissue in plants. Xylem is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem is responsible for transporting sugars and other organic compounds from the leaves to the rest of the plant. These two tissues work together to provide support and nutrients to the plant.

Explanation
Plants that produce colorful and fragrant flowers are using sexual reproduction in order to produce offspring. Sexual reproduction involves the fusion of male and female gametes, resulting in genetic diversity and the creation of new combinations of traits. This allows for adaptation to changing environments and increases the chances of survival for the offspring.
