Question

1. the most basic unit of inheritance is known as a (a) phenotype (b) genotype (c) chromosome (d) gene
2. which of the following is a sedimentary rock? (a) granite (b) marble (c) shale (d) slate
3. a producer is also known as a(n): (a) heterotroph (b) saprotroph (c) autotroph (d) scavenger
4. a vulture would be considered a (a) producer (b) decomposer (c) scavenger (d) parasite

Explanation:

1. Genes are segments of DNA that code for specific traits and are the basic units of inheritance. Phenotype is the observable traits, genotype is the genetic makeup, and chromosomes are structures containing genes.
2. Shale is a sedimentary rock formed from the compaction of clay - sized sediment. Granite is an igneous rock, marble is a metamorphic rock formed from limestone, and slate is a metamorphic rock.
3. Producers are organisms that can make their own food through photosynthesis and are also known as autotrophs. Heterotrophs rely on other organisms for food, saprotrophs feed on dead organic matter, and scavengers feed on dead animals.
4. Vultures feed on the carcasses of dead animals, making them scavengers. Producers make their own food, decomposers break down dead organic matter into simpler substances, and parasites live on or in a host organism.

Answer:

1. D. gene
2. C. shale
3. C. autotroph
4. C. scavenger
