Answer the following question given this paragraph: What makes the heart form during development? What makes the skin form? What makes a structure become an arm instead of a leg? These processes occur during development because of a highly specific pattern of gene expression. This intensely regulated pattern of gene expression turns genes on in the right cell at the right time, such that the resulting proteins can perform their necessary functions to ensure proper development. Transcription factors play an extremely important role during development. Many of these proteins can be considered master regulatory proteins , in the sense that they either activate or deactivate the transcription of other genes and, in turn, these secondary gene products can regulate the expression of still other genes in a regulatory cascade. Homeobox genes and gap genes are important classes of transcription factors utilized during development. Q: What kind of proteins either activate or deactivate the transcription of other genes? A:

OPTIONS:
- carbon proteins
- perfect regulatory proteins
- master complex proteins
- master regulatory proteins

Answer: master regulatory proteins

Problem: OPTIONS:
- pus
- progesterone
- pancreatic enzymes
- sebum
Q: Answer the following question given this paragraph: Sebaceous glands are commonly called oil glands. They produce an oily substance called sebum. Sebum is secreted into hair follicles. Then it makes its way along the hair shaft to the surface of the skin. Sebum waterproofs the hair and skin and helps prevent them from drying out. Q: What oily substance prevents the hair and skin of living things from drying out? A:
Answer: sebum

Problem:OPTIONS:
- muscle
- cuticle
- membrane
- cartilage

Answer the following question given this paragraph: Cartilage is a tough, flexible connective tissue that contains the protein collagen. It covers the ends of bones where they meet. The gray tissue in Figure below is cartilage. Q: What is the term for tough, flexible connective tissue that contains the protein collagen? A:
****
A: cartilage

Answer the following question given this paragraph: Insects have six legs and a pair of antennae for sensing chemicals. They also have several eyes and specialized mouthparts for feeding. Q: Insect's antennae are useful for sensing what? A:
OPTIONS:
- contaminants
- microorganisms
- sunlight
- chemicals
chemicals

Answer the following question given this paragraph: Q: By how many weeks do all major organs start developing? A:
OPTIONS:
- 4
- 12
- 9
- 8

Answer: 8

input with options: Answer the following question given this paragraph: 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. Q: Deletions remove one or more what from the dna? A:
OPTIONS:
- codons
- exons
- genes
- nucleotides
output:
nucleotides
