Answer the following question given this paragraph: Reptile eggs are amniotic, so they can be laid on land instead of in water. Q: What characteristic of reptile eggs allows them to be laid on land instead of in water? Choices: - they are dry - they trap gas - they are circular - they are amniotic A:
they are amniotic

Answer the following question given this paragraph: energy is released when particles in the nucleus of the atom are rearranged. (e) Chemical energy results from the particular arrangement of atoms in a chemical compound; the heat and light produced in this reaction are due to energy released during the breaking and reforming of chemical bonds. Electrical energy, nuclear energy, and chemical energy are different forms ofpotential energy (PE), which is energy stored in an object because of the relative positions or orientations of its components. A brick lying on the windowsill of a 10th-floor office has a great deal of potential energy, but until its position changes by falling, the energy is contained. In contrast, kinetic energy (KE) is energy due to the motionof an object. When the brick falls, its potential energy is transformed to kinetic energy, which is then transferred to the object on the ground that it strikes. Q: Chemical energy results from the particular arrangement of atoms in a chemical compound; the heat and light produced in this reaction are due to energy released during the breaking and reforming of what? Choices: - acid bonds - atom bonds - carbon bonds - chemical bonds A:
(Answer)
chemical bonds
Ques: Answer the following question given this paragraph: In physics, a quantity, such as mass, length, or speed that is completely specified by its magnitude and has no direction is called a scalar . A vector , on the other hand, is a quantity possessing both magnitude and direction. A vector quantity is typically represented by an arrow-tipped line segment. The length of the line, drawn to scale, represents the magnitude of the quantity. The direction of the arrow indicates the direction of the vector. Not only can vectors be represented graphically, but they can also be added graphically. Q: What do vectors possess that scalars do not? Choices: - height and polarity - direction and texture - magnitude and weight - magnitude and direction A:
Ans: magnitude and direction
(Q).
Answer the following question given this paragraph: Genetic drift is a random change in allele frequencies that occurs in a small population. When a small number of parents produce just a few offspring, allele frequencies in the offspring may differ, by chance, from allele frequencies in the parents. Q: What is the term for a random change in allele frequencies that occurs in a small population? Choices: - evolution - speciation - mutation - genetic drift A:
(A).
genetic drift
Ques:Answer the following question given this paragraph: Fossils are the preserved remains or traces of organisms that lived long ago. They form mainly when minerals in water turn remains to stone. Fossils can be dated using methods such as carbon-14 dating or their positions in rock layers. Q: What term is defined as the preserved remains or traces of organisms that lived during earlier ages? Choices: - bones - waste - deposits - fossils A:

Ans:fossils
Ques: Answer the following question given this paragraph: Flowering vascular plants also have diverse leaves. However, the leaves of all flowering plants have two basic parts in common: the blade and petiole (see Figure above ). The blade of the leaf is the relatively wide, flat part of the leaf that gathers sunlight and undergoes photosynthesis. The petiole is the part that attaches the leaf to a stem of the plant. This occurs at a node. Q: The leaves of all of what type of plants have two basic parts in common: the blade and petiole? Choices: - perennials - deciduous - evergreen - flowering plants A:
Ans:
flowering plants
