Answer:
It must be large particles move into cells, unless there is another option
Explanation:
Passive transport does not require energy, so the first one is incorrect
Particles are moved from areas of high concentration to an area of low concentration, so the last one is also incorrect
So it should be large particles can move into cells, unless of course there is another option
A mitochondrion is an organelle that produces energy
Answer:
Anaphase
Explanation:
Before the mitosis process (where cells multiply creating two new daughter cells from a single cell) chromosomes are replicated and remain attached to their replicates, then they are condensed forming microtubules as they align on the metaphase plate. <em>Now the sister chromatids (replicates) begin to separate to the opposite poles due to the action of the spindle in </em><u><em>anaphase</em></u> (You can observe this in the image I added). Then telophase begins when the nuclear envelope forms back again and chromosomes begin to unroll.

The options attached to this question are given below:
A. Their masses are always equal.
B. Each element always contributes the same number of atoms.
C. Atoms of different elements always combine in the same way.
D. Their volumes are always equal.
ANSWER
The correct option is C.
John Dalton was an English Chemist, he was the one who proposed the statements that are called Dalton's atomic theory. The theory is made up of five main points, they include the following:
1. All matters are made up of atoms.
2. Atoms of the same elements are identical.
3. Atoms of different elements vary in size and mass.
4. Compounds are formed when elements combined in whole ratios.
5. A chemical reaction result in rearrangement of the atoms in the reactants to form products.
Dalton atomic theory has been extensively revised.
<span>Euglena is autotrophic and has a chloroplast. Euglena can photosynthesize and make its own food.
Zooflagellates cannot photosynthesize and cannot make their own food. So, Euglena is considered phytoplankton and Zooflagellates are considered zooplankton.</span>
