the variable that is changed in a valid experiment, to test the effect it has on another variable

Independent variable

Chemical messengers that travel in the blood

hormones

________________ refers to movement of a substance from high concentrations to low concentration

diffusion

Part of the male reproductive system that directs sperm in the right direction, down uretha and not into bladder

prostate

These neurons take messages from receptors to the CNS

sensory neurons

the variables that are kept the same in a valid experiment.

Control variable

Nerve cells are called

neurons

part of the scientific report that describes the purpose of the experiment.

aim

Flushing of the face when one is hot is due to ____________ of the surface blood vessels

vasodilation

Name three conditions the body keeps at a steady state

pH, temperature, blood pressure, blood oxygen, blood glucose

movement of heat in a fluid is called

convection current

How nutrients move from the digestive system into the blood

diffusion

Name three organs in the body that secrete hormomes

pancreas, ovaries, testes, thyroid gland, adrenal glands

at subduction zones, these are more common

volcanoes

tube that carries sperm from the testes to urethra

sperm duct

Name three types of plate boundary

transform, divergent, convergent

Which two organ systems work together to provide nutrients to cells

digestive and circulatory systems

Two continental tectonic plates moving towards each other can cause this landform

mountains

Name a biotic factor in an aquatic ecosystem

type of fish, whales, phytoplankton, corral, seaweed

female gonad- where the ovum is released from

ovary

which molecule is bigger, starch or glucose?

starch

When blood vessels expand or get larger, this is called

vasodilation

Substances dissolved in gas or liquid move down their concentration gradients until the concentration is the same throughout. This is called

diffusion

refers to how close a measurement is to the true value.

bull's eye!

accuracy

precision

validity

The nerves that connect the CNS to the rest of the body are part of the

Peripheral Nervous System

The body does this to cool down by evaporation of moisture from the skin to remove heat.

sweating

used to measure current in an electrical circuit

ammeter

Process of one tectonic plate sliding under the other

subduction

can molecules pass through the cell membrane

yes

Type of circuit used in homes

parallel

Protein molecules that catalyse biological reactions

enzymes

This refers to maintaining a steady state of internal conditions such as temperature and pH in living things.

homeostasis

units for electrical current

amperes

Name an abiotic factor in an aquatic ecosystem

amount of sunlight, temp of water, rocks, salinity, turbidity, depth,

Which two organ systems work together to provide oxygen to cells and remove carbon dioxide?

respiratory and circulatory systems

Name three hormones secreted by the body

oestrogen, progesterone, testosterone, insulin,

The brain and spinal cord are a part of the

Central Nervous System

Site in female reproductive systems where fertilization occurs

oviduct or Fallopian tube

part of female reproductive system that forms barrier between the vagina and the uterus

cervix

Part of the scientific report that describes the step by step instructions to conduct the experiment

method

the variable that is measured as the effect in a valid experiment.

Dependent variable

when components share the same path in electrical circuit, they are in

series

When blood vessels contract or get smaller, this is called

vasoconstriction

System responsible for making copies of the organism in multicellular organisms

Reproductive system

To measure liquids accurately, you should use

measuring cylinder

When a message travels from one neuron to another , it crosses a gap called the ___________gap between neurons the messages cross is called

synapse

Name a structural adaptations of a wombat

rearward facing pouch, large front claws, thick fur, square, hard bottom.
