Since this is old, im just gonna get these points, don't wan't them to go to waste lm.ao
Explanation:
Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
During mitosis, chromosomes are moved and separated through the use of spindles composed of microtubule structures.
Explanation:
Throughout mitosis, the chromosomes are initial replicated (copied) and so distributed into a pair of new "daughter" cells. They're replicated throughout the S section of interphase, and within the following phases (prophase, metaphase, anaphase, telophase) are organized, separated, and repackaged at opposite ends of the cell, at that purpose the cell divides. The strand of chromosomes split just like the cell throughout the cellular division. They split in half.
Answer:
A stork eating fish with its beak = Predator/Prey
Fungi absorbing nutrients = Parasitism
Barnacles = Commensalism
Explanation:
A stork eating a fish is hunting, the stork is predator and the fish is prey.
The fungi is parasitism because it is benefiting while causing harm to its host.
The barnacles are commensalism, because they benefit from the whale but don't harm it.
