D is the right answer
But then again it is actually wrong... Either way D is the answer
I am pretty sure that the layer in figure 4-1 which forms the cap rock for the oil trap is the layer F that shows an example of stratigraphic traps that includes unconformity, lens, pinch-out in which you can see how t<span>he oil is stuck inside the porosity of the rocks.
Do hope you will find it helpful! Regards.</span>
Answer:
The correct answer is A DNA is replicated before mitosis begins
Explanation:
DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.
DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.
DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.
Sexual reproduction is a form of reproduction where two gametes fuse together. Each gamete contains half the number of chromosomes of normal cells. They are created by a specialized type of cell division, which only occurs in eukaryotic cells, known as meiosis.
So i'm gonna say that the answer is..B. helped maintain a slow rate of evolutionary change.
The model of the structures of the cell and and their functions is given in the image attached.
<h3>What are the cell structure and their functions?</h3>
Some explanation on structure of cells is given below:
The nucleus:
This is known to be the key or major organelle that tends to sustain or hold the genetic information that is needed for reproduction and cell growth as well as development.
Note that all cell is known to be made up of one nucleus and also a kind of membrane-bound organelles that can be seen in the cytoplasm.
Mitochondria:
This is known to be a double membrane-bound organelle that is known to function by acting as the site for the energy transactions and it is made for the survival of all cell.
Therefore, The model of the structures of the cell and and their functions is given in the image attached.
