Genetics is the study of genes and heredity.

Who was Charles Darwin?

He was the scientist who uncovered the Theory of Evolution.

Cellular Respiration is important because _____________________.

It uses O2 and sugar to produce energy (ATP)

Photosynthesis is a chemical reaction that is important because ______________.

It uses CO2 to produce sugar for producers and O2 as waste.

A cell membrane is said to be a bilayer. What forms the two layers?

Phospholipid molecules that self-arrange tail-to-tail.

The cell membrane could best be described as a

part of the cell that controls what enters and leaves the cell

What is the role of nucleolus?

Assembly of Subunits of Ribosomes.

The membrane is hydrophobic and doesn't allow water-soluble molecules to pass, yet water itself can permeate cell

Channels called aquaporins in the membrane allow water molecules to pass.

6
A cell membrane is said to be a bilayer. What forms the two layers?
Phospholipid molecules that self-arrange head-to-head.
Aquaporins and proteins with opposite charges.
roteins and carbohydrates with electron affinities.
Phospholipid molecules that self-arrange tail-to-tail.
7
What is an organism?
A living thing
An organ
A toy
Food
8
The cell membrane could best be described as a
a thin but strong physical wrapper that protects the cell
part of the cell that controls what enters and leaves the cell
skin that provides a barrier between the interior and exterior of the cell.
sieve that lets fluids flow between the interior and exterior of the cell
9
What is the role of nucleolus?
Photosynthesis
Protein synthesis.
Assembly of Subunits of Ribosomes.
Controls the substances going inside and out of the cell.
10
Embedded proteins in the cell membrane span the width of it and “poke out” on the inside and the outside are called
glycoproteins.
transmembrane proteins.
peripheral membrane proteins.
cholesterol.
11
The membrane is hydrophobic and doesn't allow water-soluble molecules to pass, yet water itself can permeate cell
The membrane is fallible and sometimes water leaks through.
Water molecules can't pass through the membrane. The water inside stays.
Sometimes the membrane will mistake water molecules for lipids.
Channels called aquaporins in the membrane allow water molecules to pass.
