Answer the following question given this paragraph: Global air currents affect precipitation. How they affect it varies with latitude ( Figure below ). Where air rises, it cools and there is precipitation. Where air sinks, it warms and causes evaporation. These patterns are part of the global wind belts. Q: The rising and sinking of these can cause precipitation? Choices: - underwater currents - circular air currents - temporary air currents - global air currents A:
(Answer)
global air currents
Ques: Answer the following question given this paragraph: As the organism grows more sophisticated, gene regulation becomes more complex, though prokaryotic organisms possess some highly regulated systems. Some human genes are controlled by many activators and repressors working together. Obviously, a mutation in a cis-regulatory region, such as the promoter, can greatly affect the proper expression of a gene. It may keep the gene permanently off, such that no protein can be made, or it can keep the gene permanently on, such that the corresponding protein is constantly made. Both of these can have detremental effects on the cell. Q: As the organism grows more sophisticated, what happens to the process of gene regulation? Choices: - degenerates - becomes fractured - becomes simplified - becomes more complex A:
Ans: becomes more complex
(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: The three types of plant cells are found in each of the major types of plant tissues: dermal, ground, and vascular tissues. Dermal tissue covers the outside of a plant in a single layer of cells called the epidermis. It mediates most of the interactions between a plant and its environment. Ground tissue makes up most of the interior of a plant. It carries out basic metabolic functions and stores food and water. Vascular tissue runs through the ground tissue inside a plant. It consists of bundles of xylem and phloem, which transport fluids throughout the plant. Q: What type of tissue covers the outside of a plant in a single layer of cells called the epidermis? Choices: - dorsal - mucous - anterior - dermal A:

Ans:dermal
Ques: Answer the following question given this paragraph: An alkaline battery is a variation on the zinc-carbon dry cell. The alkaline battery has no carbon rod and uses a paste of zinc metal and potassium hydroxide instead of a solid metal anode. The cathode half-reaction is the same, but the anode half-reaction is different. Q: Deficiency of what is symptomized by nausea, fatigue and dizziness, and can be triggered by excessive sweating? Choices: - impurities - salts - calories - electrolytes A:
Ans:
electrolytes
