ENDOCRINE SYSTEM
This system produces hormones that regulate growth, metabolism, and reproduction.
endocrine system
This system uses electrical signals to send messages quickly throughout the body.
nervous system
This is any change in the DNA sequence of an organism.
mutation
This hormone triggers ovulation in females.
Luteinizing Hormone (LH)
This term refers to the increase in the number of individuals in a population over time.
population growth
These chemical messengers travel through the bloodstream to target organs.
hormones
These neurons detect changes in the internal and external environment.
sensory neurons (receptors)
This mutation happens when one DNA base is replaced by another.
silent/substitution mutation
This hormone thickens and maintains the uterine lining.
progesterone
This happens when organisms compete for limited food and space.
competition
This gland releases hormones that help regulate other endocrine glands.
pituitary gland
This part of the brain acts as the control center for temperature regulation.
hypothalamus
This mutation occurs when part of the DNA sequence is removed.
deletion mutation
This hormone stimulates follicle development in the ovaries.
FSH
SURPRISE!
-300
This hormone helps regulate sperm production in males.
FSH (Follicle-Stimulating Hormone)
This feedback mechanism helps maintain stable body conditions like temperature.
negative feedback
This process ensures that each new cell receives an identical copy of DNA.
duplication
This hormone surge is caused by rising estrogen levels before ovulation.
LH surge
These species threaten biodiversity by outcompeting native organisms.
invasive species
This feedback mechanism increases hormone release, such as during childbirth or ovulation.
positive feedback
In temperature regulation, this structure sends signals to effectors like sweat glands.
hypothalamus
This is why deletion mutations can seriously affect an organism.
They change the amino acid sequence of proteins
This hormone regulates contractions during childbirth through positive feedback.
oxytocin
SURPRISE!
