What often happens to a cell if the damage to it cannot be fixed?
It dies.
Cells have numerous mechanisms to correct mistakes. If mistakes cannot be fixed, imperfect cells will often undergo apoptosis, or programmed cell death, so they do not create more faulty DNA.
It replicates wildly.
Nothing
Other cells eat it.

Plants perform photosynthesis because it creates the food and energy that they need for growth and cellular respiration. Most of this process occurs in the leaves of the plants.
Liquidation
Reproduction

What powers human cells?
Sunlight
Food
The saying "you are what you eat" is actually true! Humans take in the large biological molecules from food, like proteins and carbohydrates, and use them to power their cells.

Which of these can damage DNA?
Random chance
UV Light
Certain chemicals
All of the above
There are numerous environmental factors that can affect DNA. However, spontaneous chemical reactions which damage DNA can occur even without environmental factors.

Which of these things are characteristics of a living organism?
Eating
Reproduction
Secretion
All of the above
Biology is the study of life, which makes defining and understanding living things a key part of it. All living things share some version of these characteristics: eating, movement, reproduction, breathing, growing, excretion, secretion and circulation.

What can a Punnett Square be used to predict?
Allele combinations
A Punnett Square is a tool which can be used to predict genotypes and phenotypes. Genotypes are combinations of alleles, and phenotypes are the observable traits that these alleles create.
Exact height
Intelligence
Lifespan

All living things adhere to the basic rules of:
Mitosis
Gene theory
Chemistry
All living things are made of atoms, which form bonds with each other. These particles all adhere to the basic rules of chemistry.
Philosophy

Which of these is necessary for life as we know it?
Sunlight
Water
Water is a key component of life as we know it and it makes up 55%-60% of adult human bodies. Water is an excellent solvent, moves easily through living membranes and has thermal properties which make it excellently suited to help create and sustain life.
Calcium
Dust

Does DNA damage and errors always cause cancer?
Yes
No
DNA errors and damage are actually very common and usually corrected within the body. In most cases, they do not cause cancer or even small mutations.

Plant and animal cells are:
Transcendent
Eukaryotic
Prokaryotic cells are often single-celled non-complex organisms without a defined structure. Eukaryotic cells have defined structures and make up multicelled organisms, like plants and humans.
Sedimentary
Prokaryotic

Which of these is the genetic material of all living organisms?
Uranium
Water
DNA
DNA is a polymer that appears deceptively simple. All living things on earth share the same DNA.
Carbohydrates

Advertisement

Cells in the human body communicate with each other via a process called:
Photosynthesis
Gentrification
Cell signaling
Cells constantly "talk" to each other by sending chemical signals. This process is called cell signaling and allows cells to better coordinate their activities.
Fission

Which of these organelles has been described as "the powerhouse of the cell"?
Centrosomes
Smooth endoplasmic reticulum
Lysosomes
Mitochondria
Mitochondria play many roles within the cell. One of the most important is being a key part of the metabolic pathway, which is key to carbohydrate and energy metabolism.

Do cells have methods of preventing and fixing mutations?
Yes
Cells do their best to prevent mutations or permanent changes in the DNA sequence. They make corrections through proofreading, mismatch repair, chemical reversal, excision repair and double-stranded break repair.
No

What type of cells lack structure?
Meteoric
Isosceles
Prokaryote
Prokaryotic cells do not have a defined structure and are often found in single-celled organisms. Eukaryotic cells are rigidly structured and found in complex multi-celled organisms.
Sedimentary

What is it called when a single cell divides to create two identical cells?
Scoliosis
Mitosis
Mitosis is a type of cell division that is often referred to as binary fission. It is when a cell divides to create two genetically identical daughter cells.
Photosynthesis
Ribosomal Defect

Which part of the cell plays a key part in photosynthesis?
Ribosomes
Cell wall
Chloroplasts
Chloroplasts are green because they contain chlorophyll. They help living organisms transform light energy into fuel so they can function and thrive.
Endoplasmic reticulum

What do plant cells have that animal cells don't?
Walls
Plant cells and animal cells share some similarities, but also have some differences. Plant cells have cell walls, which help transport water and solutes through plant tissue.
Atoms

Can you use Punnett Squares to answer every genetics problem?
Yes
No
While Punnett Squares can be helpful for representing the probability of genetic expression visually, they are not ideal for all of them. For example, for complex combinations of traits, you may need to draw a Punnett Square with thousands of boxes.

Which of these is an organelle?
Mitochondria
Cytoplasm
Cell membrane
All of the above
Cell structure can vary depending on the type and function of the cell. However, all plant and animal cells contain organelles. Organelles are specialized structures within cells that perform specific tasks.

Was Johann Gregor Mendel respected for the contributions he made to the study of genetics during his lifetime?
Yes
No
Mendel's work disagreed with popular opinion at the time, which was that the traits of parents blended perfectly in their offspring. It was most likely considered too mathematical and confusing by many of his peers. Due to this, he went largely unrecognized during his life.
