Q: Answer the following question given this paragraph: Some of the specialized cells grow short, sharp projections called spicules. Spicules make up the sponge's internal skeleton, or endoskeleton. The endoskeleton helps to support and protect the sponge. Q: What are the sharp projections that specialized cells grow called? A:

OPTIONS:
- ossicles
- cilia
- antlers
- spicules

A: spicules

input: OPTIONS:
- decay rate
- full-life
- deterioration rate
- half-life Now, answer this question: Answer the following question given this paragraph: The disintegration of unstable nuclei does not occur all at once. The rate of disintegration is a statistical process. The most convenient way to consider it is by a concept known as half-life . The time required for half of the atoms in any given quantity of a radioactive substance to decay is the half-life of that element. Each particular isotope has its own half-life. For example, the half-life of radium-226 is 1600 years. That is, beginning with 1.00 gram of radium-226, it would take 1600 years for half of it to decay and leave 0.50 gram remaining. After another 1600 years, only 0.25 gram would remain. In each half-life, exactly half of the beginning amount decays. Q: What is the time it takes for radioactive substance to decay? A:
A:
output: half-life

Question: Answer the following question given this paragraph: Since natural selection acts on the phenotype, if an allele causes death in a homozygous individual, aa , for example, it will not cause death in a heterozygous Aa individual. These heterozygous Aa individuals will then act as carriers of the a allele, meaning that the a allele could be passed down to offspring. People who are carriers do not express the recessive phenotype, as they have a dominant allele. This allele is said to be kept in the population's gene pool. The gene pool is the complete set of genes and alleles within a population. Q: What is the term for the complete set of genes and alleles within a population? A:
OPTIONS:
- the ancestral pool
- the chromosomal pool
- the biodiversity pool
- the gene pool
Answer:
the gene pool
