Untitled Quiz

A Good Hypothesis

• A good hypothesis is a testable and falsifiable statement.
• It predicts a relationship between variables and can be supported or rejected through experimentation.

Scientific Method Steps

• The scientific method follows a specific order: observation, question, hypothesis, prediction, experiment, analysis, and conclusion.

Properties of Life

• All living things share essential properties, including organization, metabolism, responsiveness, growth and development, reproduction, and adaptation.

Smallest Unit of Matter

• The smallest unit of matter is an atom.

Eukaryotic Cell Example

• A plant cell is a eukaryotic cell.

Not a Tissue Type

• Blood is not classified as a type of tissue.

Autotrophs vs. Heterotrophs

• Autotrophs produce their own food through processes like photosynthesis, while heterotrophs obtain nutrients from other organisms.

False Taxonomy Statement

• A statement that all organisms in the same genus must share the same species is false.

Polymer Formation

• Dehydration synthesis is the primary process involved in forming a polymer from monomers.

Polysaccharide Bond

• Glycosidic bonds link monosaccharides together to form polysaccharides.

Highest Resolution Microscopy

• Electron microscopy offers the highest resolution for observing cell structures.

Saturated vs. Unsaturated Fats

• Saturated fats lack double bonds between carbon atoms, while unsaturated fats have at least one double bond.

Prokaryotic vs. Eukaryotic Cells

• Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have a nucleus and other membrane-bound organelles.

ATP Production

• Mitochondria are primarily responsible for ATP production within a cell.

Ribosome Function

• Ribosomes are responsible for protein synthesis within a cell.

Lipid Property Preventing Mixing with Water

• Lipids are hydrophobic, meaning they are "water-fearing" and do not mix well with water due to their nonpolar nature.

Charles Darwin's Theory

• Darwin's theory of evolution by natural selection proposes that organisms with traits that are better suited for their environment are more likely to survive and reproduce, passing on those favorable traits to their offspring.

Postulate of Natural Selection

• The assumption that individuals within a population vary in their traits is a key postulate of natural selection.

Matter Definition

• Matter is anything that has mass and takes up space.

Atomic Structure Truth

• The nucleus of an atom contains protons and neutrons, while electrons orbit the nucleus.

Electron Transfer Bond

• Ionic bonds are formed through the transfer of electrons.

Water Property from Polar Nature

• Water's ability to form hydrogen bonds is a consequence of its polar nature.

Basic Substance pH Range

• A basic substance has a pH range higher than 7.

Electronegativity

• Electronegativity refers to an atom's tendency to attract electrons when forming a bond.
