a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.

Define traits
Traits are distinguishing qualities or characteristic, typically one belonging to a person.
100
Which one forms from asexual reproduction?
Mitosis
100
What are some benefits of asexual reproduction?
Don't need no mate, and can reproduce faster than your grandma can walk.

WHAT IS HEREDITY?
heredity is the passing on traits from parents to offspring
200
Who do our chromosome traits come from?
Our parents
200
Define genes and variation
Variation- A different or distinct form or version of something.
Genes- Is a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring
200
Which one has 8 phases?
Meiosis
200
What is a Zygote?
A zygote is a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
200
WHAT IS UNIFORMITARIANISM?
the theory that changes in the earth's crust during geological history have resulted from the action of continuous and uniform processes
300
What is a Diploid?
cells that have pairs of chromosomes
300
What are some benefits of sexual reproduction?
-Intelligence, variety of diversities, more able to adapt to an environment, large and complex organisms.
300
What does Mitosis do and what are the 4 stages?
Mitosis is when the nucleus and its contents divide. Mitosis is associated with Asexual reproduction.
The 4 stages are 1) Prophase 2) Metaphase, 3) Anaphase 4) Telophase

What is RNA and what are the pairs?
It is Ribonucleic Acid and it is present on all living cells. Its main job is to act like a messenger carrying instructions from DNA for controlling the synthesis of proteins.
The pairs are: Adenine + Uracil
Cytosine + Guanine
300
WHAT ARE TRACE FOSSILS?
a fossil of a footprint, trail, burrow, or other trace of an animal in a rock or in old sediment.
400
What is a Haploid?
A haploid are cells that have only one chromosomes from, each pair.
400
What is diversity and what is it in the science world?
Diversity is a range of different things.
This is what diversity is in the science world:
1. Diversity is critical to excellence
2. Lack of diversity represents a loss of talent
3. Enhancing diversity is key to long-term economic growth and global competitiveness
400
What does Meiosis do and how many stages are there?
Meiosis is cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number.
There are 8 stages.
400
What does DNA stand for?
Deoxyribonucleic Acid
400
WHAT ARE P&S WAVES?
P waves: fastest, can go through solid rocks and water, go up and down, and animals can hear them before we do.
S waves: slowest but more powerful, cannot go through water, goes up and down, and only go through rock.
500
How many chromosomes do humans have?
In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.

What is natural selection and who discovered it?
Natural selection- For survival if an organism can pass on certain traits and have more offspring they will have a great chance to survive.
Charles Darwin discovered Natural Selection.
