Answer:
Phenotype- 100% for the recessive trait (aa, bb)
Explanation:
This happens because of the mode of inheritance, which would mask the dominant trait, during a cross. Therefore, this would lead to all offspring not expressing the dominant phenotype
The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.
<h3>Tumor suppressor genes </h3>
Tumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.
A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.
The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.

That's called evolution. I'm not sure exactly what it's asking, but I hope this helps you
Charles Darwin's evolutionary theory enables us to establish cause and effect in biology, including those associated with a person's overall character. The evolutionary biologist Theodosius Dobzhansky wrote: "Nothing in Biology Makes Sense Except in the Light of Evolution". It's a well-known statement on the evolutionary theory and their implications in all spheres of biology
Answer:
1. Support
2. Protection
3. Movement
4. Supply & Storage
Explanation:
1. Support : It provides a framework to support the organs and tissues of the body.
2. Protection: It protects our internal organs. The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).
3. Movement: It provides a framework for muscles to attach. Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.
4. Supply & Storage: The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
