Answer the following question given this paragraph: Heat expansion is a result of the increase of kinetic energy of the molecules. As their movement increases, they bump into each other more and the material slightly expands as a result. Most materials expand with heat. Water is a particularly interesting substance in that it contracts as its temperature increases from to (and then expands from to ). Q: Heat expansion is a result of the increase of what type of energy, exhibited by molecules bumping together? Choices: - light energy - radioactivity - harmonic energy - kinetic energy A:
kinetic energy

Answer the following question given this paragraph: Translation is the RNA protein part of the central dogma. It occurs at a ribosome. During translation, a protein is synthesized using the codons in mRNA as a guide. All three types of RNA play a role in translation. Q: What exactly happens during rna translation? Choices: - carbohydrate is synthesized - membrane is synthesized - chromosome is synthesized - protein is synthesized A:
(Answer)
protein is synthesized
Ques: Answer the following question given this paragraph: Figure 2.13 Carbon can form four covalent bonds to create an organic molecule. The simplest carbon molecule is methane (CH4), depicted here. Q: What is the name of the simplest carbon molecule? Choices: - Buckminsterfullerine - graphite - butane - methane A:
Ans: methane
(Q).
Answer the following question given this paragraph: Organisms that reproduce sexually by joining gametes , a process known as fertilization , must have a mechanism to produce haploid gametes. This mechanism is meiosis , a type of cell division that halves the number of chromosomes. Meiosis occurs only in gamete producing cells within the gonads. During meiosis the pairs of chromosomes separate and segregate randomly to produce gametes with one chromosome from each pair. Meiosis involves two nuclear and cell divisions without an interphase in between, starting with one diploid cell and generating four haploid cells ( Figure below ). Each division, named meiosis I and meiosis II, has four stages: prophase, metaphase, anaphase, and telophase. These stages are similar to those of mitosis, but there are distinct and important differences. Q: What is the process in which organisms reproduce sexually by joining gametes called? Choices: - propagation - migration - stimulation - fertilization A:
(A).
fertilization
Ques:Answer the following question given this paragraph: Human Reproductive Anatomy The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male gonads. Testosterone causes the undeveloped tissues to differentiate into male sexual organs. When testosterone is absent, the tissues develop into female sexual tissues. Primitive gonads become testes or ovaries. Tissues that. Q: The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male what? Choices: - kidneys - liver - bladder - gonads A:

Ans:gonads
Ques:Answer the following question given this paragraph: Q: In multicellular organisms, only mutations in cell lines that produce gametes can be passed to what? Choices: - cells - clones - proteins - offspring A:

Ans:
offspring
