A karyotype is the apperance of chromosomes in the cells' nuclei. so it's C
Answer:
1/64
Explanation:
Parent 1: AaBbCc
Parent 2 : AaBbCc
When the cross is checked for individual gene:
Aa X Aa =
A a
A AA Aa
a Aa aa
Probability of producing an AA organism is 1/4
Similarly, probability of producing a BB from Bb X Bb would be 1/4
Probability of producing a CC from Cc X Cc would be 1/4
Hence, probability of producing an AABBCC would be:
1/4 * 1/4 * 1/4 = 1/64
Answer and Explanation:
The cell is a basic functional and structural unit of life. All living organisms are made up of cells. The human body contains approximately 100 trillion cells in our blood, skin, nerves, muscles, bones, and brain. Humans have 200 diverse forms of cells that come in different sizes and shapes. Each cell performs a specific function in the human body. There are four main types of cells: nerve cells, muscle cells, epithelial cells, and connective tissue cells. Nerve cells are specific for communication. These cells send signals from the brain to glands and muscles that control functions. Nerve cells receive sensory information is from the skin, the ears, and the eyes and send this information to the brain. Epithelial cells cover the interior of hollow body organs such as digestive organs or blood vessels. Muscle cells are specific for contraction. The body cannot move without muscles. Connective tissue cells protect against foreign invaders and also provide strength to the body.
The earliest modern humans in Australia, dating to 50 - 40,000 yBP, were found at Lake Mungo. Early modern humans moved into North and South America because of population increase, competition for food and climate change. Modern humans likely migrated to the Americas via walking across the Being land bridge.
