Nervous & Endocrine Systems
What is the primary function of the nervous system?
To control and coordinate the body's responses to internal and external stimuli
What is the main male reproductive organ that produces sperm?
The testes
What is the purpose of mitosis?
What is the basic unit of heredity?
A gene
What term describes the number of individuals per unit area?
Population Density
Which gland is responsible for regulating metabolism and energy levels in the body?
The thyroid gland
During which tage of pregnanct does the fetal heartbeat first become detectable?
~ 6 weeks
In which phase of mitosis do chromosomes line up in the middle of the cell?
Metaphase
What is the difference between a genotype and phenotype?
A genotype is genetic makeup; a phenotype is the physical expression.
Maximum sustainable population size?
Carrying Capacity
DOULBE JEOPARDY: Identify the part of the brain that controls coordination and movement.
The cerebellum
What provides oxygen and nutrients to the fetus and removes waste products?
The placenta
What is the difference between Mitosis and Meiosis relating to cell count?
Mitosis results in two identical cells, whereas meiosis results in four genetically diverse cells.
AA
Homozygous Dominant
A resource or environmental condition that restricts the growth, abundance, or distribution of a population is called:
A limiting factor
Which neurotransmitter is involved in the "fight or flight" response?
Adrenaline (epinephrine)
name the hormone responsible for the contraction of the uterus during childbirth.
Oxytocin
DOUBLE JEOPARDY: What is the structure that organizes and separates chromosomes during mitosis?
The spindle apparatus.
Genes located close to each other on the same chromosome tend to be inherited together. This is known as:
Genetic Linkage
Rapid increase in population size without limits is known as:
Exponential Growth
What is the role of insulin in the body?
Regulating blood sugar levels.
The formation of sperm cells through mitotic division, followed by meiotic division to produce haploid sperm cells is called:
Spermatogensis
The division of the cytoplasm to form two separate daughter cells is called
Cytokinesis
Purpose of a Punnett Square?
Predicting offspring traits.
When a small group of individuals, establish a new population in a new area, leading to a loss of genetic variation compared to the original population. This is called:
The Founder Effect
