Final Flashcards
DNA is made up of:
Many molecules called nucleotides.
Which is not found in a Nucleotide:
- Adenine
- Polymerase
- Phosphate
- Guanine
Polymerase
Give the complementary DNA sequence to:
- CCTATGGTACG
GGATACCATGC
True/False: You are a single celled organism..?
False
True/False: Bitter is one of the four basic taste groups
True
True/False: You are able to sense sound
True
True/False: Muscle tissue serves as a protective outer covering to body surfaces
False
True/False: Mechanoreceptors are sensitive to light
False
True/False: Your digestive system is involved in eating
True
What is the hierarchy of organization in multicellular organisms?
Cell > Tissue > Organ > Organ System > Organism
What is the hierarchy of organization in multicellular organisms?
Cell > Tissue > Organ > Organ System > Organism
Simple definition of a cell-
Basic building block of life
True/False: Thermoreceptors adapt to changes in temperature
True
True/False: If you have an ear infection, you may find it hard to keep your balance.
True
True/False: If you have a cold, you may have difficulty tasting the difference between bitter coffee and sweet strawberries
False
When you walk into a warm building after being outside on a cold winter day and you wash your hands with warm water, you will perceive the water temp as warmer than it really is. Why?
Your thermoreceptors have adapted to the winter cold.
In the sensory system lab, you determined the two-point threshold of your fingertip and compared it to the two-point threshold on the back of your hand. Your fingertip had a smaller threshold than the back of your hand. Why?
The back of your hand is less sensitive to touch than your fingertip.
Pain receptors adapt little if at all because-
Pain is a way your body tells you to stop doing whatever is causing you pain to prevent further injury.
Why did multicellularity most likely evolve?
As unicellular organisms grow, their volume increases faster than their surface area.
True/False: The blind spot is the result of a lack of photoreceptors on the retina where the optic nerve exits the eye.
True
How does a cell dispose of its waste?
Through the Plasma Membrane.
What are the different types of tissues?
Epithelial tissue, Connective tissue, Nervous tissue, and Muscle tissue
What is Epithelial tissue?
Tissue coating and protecting interior and exterior tissues.
- Provides protection and also controls what enters and exits the body.
What is Connective tissue?
Composed of cells Scattered throughout Fluid and Fibrous Extracellular Matrix.
- This category of tissue has the greatest diversity of specific tissue types.
What is Nervous Tissue?
Conducts most of the communication between the brain and the body.
- Itself composed of nerve cells.
- Controls both Voluntary and Involuntary movements.
