Cells
What is embedded in the phospholipid layer?
Protiens
Which type of mutation occurs in non-reproductive cells and cannot be passed to offspring?
somatic mutation
What are a male's chromosomes
(XY)
Are all species related?
All living species on Earth are related through a common ancestor.
What are species?
Organisms that can interbreed to produce fertile, viable offspring.
What part of the phospholipid is hydrophilic?
The heads
Why are insertion and deletion mutations often more harmful than substitutions?
They cause frameshifts that change all codons downstream of the mutation, altering the entire amino acid sequence.
What are a female's chromosomes?
(XX)
Which of the following evolutionary forces is primarily responsible for introducing new genetic variation into a population?
Mutation
What is a Community?
All the different populations (various species) that live together in a specific area.
What are the two different endoplasmic?
Smooth and Rough
diploid is?
2 sets of chromosomes
Inherited Traits?
Passed from parents to offspring, involve changes in DNA, and are transmitted to future generations
Variation in genes is called?
alleles
What is aEcosystem
A community of organisms together with their abiotic environment.
What type of cell has a cell wall?
plant cell
Haploid is?
1 set of chromosomes
Acquired Traits
Developed during an individual's lifetime due to environmental factors and cannot be passed to offspring
what is a Population?
A group of organisms of the same species living in a specific area.
What is a Biome?
A large region characterized by a specific climate and certain types of plant and animal communities.
What is the function of ribosomes?
to make proteins
What is a gamete?

In pea plants, yellow seed color (Y) is dominant over green seed color (y). If a heterozygous yellow-seeded plant (Yy) is crossed with a green-seeded plant (yy). What is the probability that an offspring will have green seeds?
50% or 1/2
Gene Pool?
