(Question)
Q: What type of cell does the sperm cell fertilize? Read this paragraph and choose the correct option from the provided answers: Together with random fertilization, more possibilities for genetic variation exist between any two people than the number of individuals alive today. Sexual reproduction is the random fertilization of a gamete from the female using a gamete from the male. In humans, over 8 million (2 23 ) chromosome combinations exist in the production of gametes in both the male and female. Essentially, when the homologous pairs of chromosomes line up during metaphase I and then are separated at anaphase I, there are (2 23 ) possible combinations of maternal and paternal chromosomes. During random fertilization, a sperm cell, with over 8 million possible chromosome combinations, fertilizes an egg cell, which also has over 8 million possible chromosome combinations. Together, there are over 64 trillion unique combinations, not counting the additional variation produced by crossing-over during prophase I. In other words, each human couple could produce a child with over 64 trillion unique chromosome combinations!. Choices: - fat - bacteria - protein - egg A:
(Answer)
egg

Ques: Q: What term describes anything that occupies space and has mass, and is generally divided into three states? Read this paragraph and choose the correct option from the provided answers: Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition. Most matter consists of mixtures of pure substances, which can behomogeneous (uniform in composition) or heterogeneous (different regions possess different compositions and properties). Pure substances can be either chemical compounds or elements. Compounds can be broken down into elements by chemical reactions, but elements cannot be separated into simpler substances by chemical means. The properties of substances can be classified as either physical or chemical. Scientists can observe physical properties without changing the composition of the substance, whereas chemical propertiesdescribe the tendency of a substance to undergo chemical changes (chemical reactions) that change its chemical composition. Physical properties can be intensive or extensive. Intensive properties are the same for all samples; do not depend on sample size; and include, for example, color, physical state, and melting and boiling points. Extensive properties depend on the amount of material and include mass and volume. The ratio of two extensive properties, mass and volume, is an important intensive property called density. Choices: - stuff - lquid - galaxy - matter A:
Ans: matter

Q: Where do oceans absorb gases from? Read this paragraph and choose the correct option from the provided answers: Oceans are an important part of the water cycle. They absorb gases from the atmosphere. They evaporate and supply water vapor to the atmosphere. Choices: - stratosphere - wind - sunlight - atmosphere A:
(A).
atmosphere

Ques:Q: What is the science of classifying living things is called? Read this paragraph and choose the correct option from the provided answers: Scientists classify living things to make sense of biodiversity and who how living things are related. The science of classifying living things is called taxonomy. Choices: - entomology - methodology - physiology - taxonomy A:

Ans:taxonomy

Ques: Q: What is the name of the procedure where an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it? Read this paragraph and choose the correct option from the provided answers: In a procedure called elemental analysis , an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it. These percentages can be transformed into the mole ratio of the elements, which leads to the empirical formula. The steps to be taken are outlined below. Choices: - electrical analysis - chemical analysis - gaseous analysis - elemental analysis A:
Ans:
elemental analysis
