Answer the following question given this paragraph: Plants can also reproduce sexually, but their reproductive organs are different from animals' gonads. Plants that have flowers have their reproductive parts in the flower. The sperm is contained in the pollen, while the egg is contained in the ovary, deep within the flower. The sperm can reach the egg two different ways:. Q: What reproductive part is stored in a plant's pollen? Choices: - the gamete - the mimic - the egg - the sperm A:
the sperm

Answer the following question given this paragraph: Basic Principles of Gas Exchange Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide. This concentration gradient allows for gas exchange during respiration. Partial pressure is a measure of the concentration of the individual components in a mixture of gases. The total pressure exerted by the mixture is the sum of the partial pressures of the components in the mixture. The rate of diffusion of a gas is proportional to its partial pressure within the total gas mixture. This concept is discussed further in detail below. Q: Gas exchange during respiration occurs primarily through what? Choices: - vaporization - secretion - activation - diffusion A:
(Answer)
diffusion
Ques: Answer the following question given this paragraph: When organisms die, they leave behind energy and matter in their remains. Decomposers break down the remains and other wastes and release simple inorganic molecules back to the environment. Producers can then use the molecules to make new organic compounds. The stability of decomposers is essential to every ecosystem. Decomposers are classified by the type of organic matter they break down:. Q: What do decomposers release back to the environment after they break down the remains and other wastes? Choices: - carbon monoxide - unrefined waste - nematodes - simple inorganic molecules A:
Ans: simple inorganic molecules
(Q).
Answer the following question given this paragraph: projectile motion: A form of motion where a particle (called a projectile) is thrown obliquely near the earth's surface, & it moves along a curved path under the action of gravity. The path followed by a projectile motion is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning of the trajectory after which there is no interference apart from gravity. Q: What type of motion only occurs when there is one force applied at the beginning of the trajectory after which there is no interference apart from gravity? Choices: - velocity - propellant - thrust - projectile A:
(A).
projectile
Ques:Answer the following question given this paragraph: Like many other animals, sheep travel in herds. The tendency is for each individual sheep to stay with the herd. However, a sheep may sometimes wander off, depending on how strong the attraction is for a particular food or water supply. At other times, a sheep may become frightened and run off. Whether a sheep chooses to stay with the herd or go its own way depends on the balance between attraction to the herd and attraction to the outside influence. Q: What is the collective travel of sheep known as? Choices: - gaggle - load - den - herd A:

Ans:herd
Question: Answer the following question given this paragraph: Q: What are the two types of vesicle transport called? Choices: - dielectric and exocytosis - epithelium and exocytosis - eptocytosis and exocytosis - endocytosis and exocytosis A:
Answer:
endocytosis and exocytosis
