A type of reaction I which two or more substances combine and form one compound

New substance formed with characteristics that are different than each of the elements that formed the compound

The left side of a chemical equation

The breaking down of a compound into its elements

This states that the total mass of the reactants before the chemical reaction is the same as the total mass after the chemical reaction

The energy in food is measured in units called…

One parent reproduction, no genetic variation

Anything in plant earth that is living or that was once living is and contains the substance carbon is

Meaning in celled

The basic units of life

The process produces sex cells Ruth at have 1/2 the chromosomes of normal cells and 4 daughter cells are produced

When plant cells use carbon dioxide and water with the suns energy to make food an oxygen

Place the following terms in order from smallest to largest

Organ, organism, cell, organ system, tissue

Also knows as cell division, where two identical daughter cells are produced

Uncontrolled (abnormal) mitosis where the cells of an organism do not know when to stop dividing

The control center of the cel, that contains the genetic information

Organelle where proteins are made

Father of genetics 🧬 that studied pea plants

The general shape of a plant cells

Number of chromosomes in human sex cells

Genetic information that codes for proteins, also known as the blue print of life

They discovered the shape of dna

Basic unit of genetics, control traits

Two different genes for a trait

What genes an organism has for example Tt

The passing of traits from parent to offspring

This occurs with sexual reproduction where offspring are different from parents

Two of the same genes for a trait for example TT

Breeding for desired traits of an organism

Both genes are expressed through a blending of the traits

The stronger trait, usually is the trait that is expressed or commonly seem

A change in a gene or chromosome

The father of evolution
