A. Not all cells have DNA.
B. Only plant cells have Chloroplasts.
C. Not all cells have Nuclei.
D. Not all cells contain Contractile Vacuoles.
None of these would be the correct answer.
Human bodies do not contain Chloroplast.
Your best bet would be A. DNA
Answer
:Photosynthesis can be explained in four simple steps, as follows.
Step 1:
The plant gathers sunlight from the chlorophyll in the cells to convert into energy.
Step 2:
The light energy then reactions and forms hydrogen and oxygen.
Step 3:
The hydrogen joins with carbon dioxide and create sugars.
Step 4:
The sugar is then separated, some to be used as the structure in the cell wall, and some stored in the ATP for later use.

Answer:
The answer to your question is:letter A
Explanation:
Data
Density = mass/ volume
In the graph we can observe that if the temperature increases 4°C, then density increases but if the temperature increases more than 4°C density diminishes.
Then as density = mass / volume
For the first part (0 - 4°C) volume diminishes and density increases.
For the second part ( 4 - 12°C) volume increases and density diminishes.
If you need to choose only one answer it would be letter A.
If you need to choose two answers, they would be A and B
The correct answer is - B. Beak size determines what the bird can eat.
The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...
