Q: What are variants of genes called? Read this paragraph and choose the correct option from the provided answers: Recall that our DNA is wound into chromosomes . Each of our chromosomes contains a long chain of DNA that encodes hundreds, if not thousands, of genes. Each of these genes can have slightly different versions from individual to individual. These variants of genes are called alleles . Each parent only donates one allele for each gene to an offspring. Choices: - antigens - mutations - allergens - alleles A:
alleles

Q: What is the preferred method for separating late transition metals from their ores? Read this paragraph and choose the correct option from the provided answers: Hydrometallurgy is the preferred method for separating late transition metals from their ores. What types of ligands are most effective in this process?. Choices: - hydraulics - purging - heating - hydrometallurgy A:
hydrometallurgy

Q: Deletions remove one or more what from the dna? Read this paragraph and choose the correct option from the provided answers: Similar to chromosomal alteration mutations, deletion or insertion mutations add or remove genetic information. Small deletions or insertions in the DNA will alter the reading frame. Deletions remove one or more nucleotides from the DNA, whereas insertions add one or more nucleotides into the DNA. These mutations in the coding region of a gene may also alter the splicing of the mRNA, known as a splice site mutation . Mutations which alter the reading frame are known as frameshift mutations . Splice site mutations and frameshift mutations both can dramatically change the mRNA, altering the final protein product. Choices: - codons - exons - genes - nucleotides A:
nucleotides

Q: What is the process bacteria use to break down chemicals into food? Read this paragraph and choose the correct option from the provided answers: The bacteria that make food from chemicals are also primary producers. These organisms do not do photosynthesis since there is no light at the vents. They do something called chemosynthesis. They break down chemicals to make food. Choices: - biosynthesis - gametogenesis - cellular respiration - chemosynthesis A:
chemosynthesis
