Q: What is the first step towards wound repair? Read this paragraph and choose the correct option from the provided answers: attracted to the sites of infections in large numbers, and as they phagocytose the pathogens and subsequently die, their accumulated cellular remains are visible as pus at the infection site. Overall, inflammation is valuable for many reasons. Not only are the pathogens killed and debris removed, but the increase in vascular permeability encourages the entry of clotting factors, the first step towards wound repair. Inflammation also facilitates the transport of antigen to lymph nodes by dendritic cells for the development of the adaptive immune response. Choices: - electrolysis factors - hormone factors - blotting factors - clotting factors A:
clotting factors

Q: How many underlying principles does the science of biology have? Read this paragraph and choose the correct option from the provided answers: Four underlying principles form the basis of biology. They are cell theory, gene theory, homeostasis, and evolution. Choices: - five - three - eleven - four A:
four

Q: Genetic equilibrium occurs when what process doesn't exist within the population? Read this paragraph and choose the correct option from the provided answers: The Hardy-Weinberg model describes how a population can remain at genetic equilibrium , referred to as the Hardy-Weinberg equilibrium. Genetic equilibrium occurs when there is no evolution within the population. In other words, the frequency of alleles (variants of a gene) will be the same from one generation to another. At genetic equilibrium, the gene or allele frequencies are stable they do not change. For example, let's assume that red hair is determined by the inheritance of a gene with two alleles R and r . The dominant allele, R , encodes for non-red hair, while the recessive allele, r , encodes for red hair. If a population's gene pool contains 90% R and 10% r alleles, then the next generation would also have 90% R and 10% r alleles. However, this only works under a strict set of conditions. Choices: - movement - reproduction - variation - evolution A:
evolution

Q: What type of eukaryotes are protists normally? Read this paragraph and choose the correct option from the provided answers: Most protists are so small that they can be seen only with a microscope. Protists are mostly unicellular (one-celled) eukaryotes. A few protists are multicellular (many-celled) and surprisingly large. For example, kelp is a multicellular protist that can grow to be over 100-meters long ( Figure below ). Multicellular protists, however, do not show cellular specialization or differentiation into tissues. That means their cells all look the same and, for the most part, function the same. On the other hand, your cells often are much different from each other and have special jobs. Choices: - multicellular - photosynthetic - immature - unicellular A:
unicellular
