The human stomach is an organ that helps us digest food. The stomach is one of many organs involved in the process of digestion. Others include the esophagus, small intestine, pancreas, and gall bladder. What name is given to a set of organs that work together to perform a specific function?
Do we call this a system?
Thee passage of genetic instructions from one generation to another.
Is this heredity?
A research program is launched to produce genetically modified varieties of a food crop. The aim of the program is to create varieties with fruit that ripen quicker.
This is an example of?
Do we call this selective breeding?
Genetic material is contained within this organelle.
What is a nucleus?
The human heart is an organ that is made up of cells. Not all of the cells that make up the heart are identical, however. What name is given to a group of similar cells that perform a special function and together make up an organ?
Do we call these a tissue?
The nucleus contains the cells genetic material in the form of DNA. DNA is organized into our chromosomes, which are made up of thousands of ________ that determine our traits.
Do we call these genes?
A cross between a male horse and female donkey results in the reproduction of a mule, which does not resemble either of the parents. What is the reason for this?
Do we call this sexual reproduction
The cell membrane controls what enters and leaves the cell.
Is the cell membrane semipermeable?
MMMMMM! Dinner's cooking. Soon we'll be eating some chicken and dumplings. Our digestive system will get to work on the food we eat. The food is moved through our digestive system with the help of what other body system?
Do we call this the muscular system?
In pea plants, wrinkled seeds (W) is the dominant trait, while smooth seeds (w) is the recessive trait. Consider the cross Ww X WW.
What will be the ratio of wrinkled to smooth seeds?

Do we call this sexual reproduction?
This organelle helps plants keep their rigid structure.
What is a cell wall?
Nutrients enter a cell with the concentration gradient by this method.
Is this diffusion?
The lungs and respiratory system work closely with this ___________ system to make sure oxygen reaches all the cells of our body.
Do we call this the circulatory system?
A portion of this DNA, known as a ________, is responsible for the inheritance of a trait, like eye color or blood type in humans.
Do we call this a gene?
Yeast cells reproduce quickly by budding. This is a form of ___________ reproduction so all the yeast cells are ____________ to the parent(s).
Is yeast created with asexual reproduction and identical to the parent?
Your stomach. The internal organ in which the major part of the digestion of food occurs, being, in humans and many mammals, a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine. Let's compare the human stomach to cellular organelles. Which organelle is involved in cellular digestion and contains digestive enzymes?
Is this a lysosome?
What is osmosis?
The movement of water molecules from a high concentration to low concentration.
The human body is capable of movement because the muscular and skeletal systems work closely together. Which other systems are MOST closely linked in function?
