Oxygen and hydrogen are kept under the same temperature and pressure. Oxygen molecule is 16 times more massive than hydrogen one
lozanna [386]

Explanation:

When we increase the temperature of a substance then there will occur an increase in the kinetic energy of its molecules.

Also,      K.E = \frac{3}{2}kT

So, kinetic energy is directly proportional to the temperature.

Hence, when temperature and pressure are kept the same for both oxygen and hydrogen gas then values of their kinetic energy will be the same irrespective of their masses.

Thus, we can conclude that kinetic energy of oxygen molecule is the same as compared to hydrogen molecule.

How are protists different from plants​
kotegsom [21]

Answer/ explanation :

Protist can be multicellular or unicellular organisms

Plants are all multicellular and also exhibit cellular differentiation.

Protist can be autotroph, heterotrophic or decomposer

Plants are only autotrophs because they manufacture their own food through photosynthesis

Protists are microscopic, more diverse and abundant in nature

Plants are big and complex in nature

Nuclear DNA strands in plants are of higher complexity than those of protist

Plants require oxygen for cellular respiration process unlike protist which can be aerobic and some other species facultative anaerobic

Plants only can reproduce asexually through bulbs and tubers as in yam, potatoes while protists reproduce either sexually through meiosis or asexually through simple cell division.
