Remember that the number of electrons are equal to the number of protons, and to find the number of protons you have to look and see the atomic mass of the atom is equal to the number of protons, and to find the number of neutrons you have too subtract the atomic mass to the atomic number.

Example:

You want to find out how many protons, neutrons, and electrons are in Platinum:

  • Atomic number is equal to the number of protons:
  • 78 = 78
  • So platinum has 78 protons and electrons.
  • Subtract atomic mass to atomic number:
  • 195 - 78 = 117 (forgetting about the decimals)

So platinum has "78 protons, and electrons, and has 117 neutrons."

Hope this helps!

Kiko writes a report to compare and contrast the cells of plants and animals. Which of the following statements is accurate and
VladimirAG [237]

Answer:

The correct answer is: Vacuoles in plants are much larger than those in animals.

Explanation:

The cell membrane of animals is not thicker than those in plants. In addition, plant cells have a thick cell wall surrounding the cell membrane that is made of cellulose and provides great protection against osmotic and mechanical stress.

Vacuoles in plants ARE much larger than vacuoles in animals, because plant cells r<u>equire much more water</u> and other substances to function properly. Animals, on the other hand, can ingest water and nutrients through food.

Animal cells DO have chromosomes. Every organism has chromosomes in their cells: prokaryotes have one single circular chromosome, while eukaryotes have many linear chromosomes (humans, for example, have 46 chromosomes).

Plant cells HAVE chloroplasts, as these organelles are crucial, since they participate in the process of photosynthesis - which is fundamental for the nourishment of the plant.

The statement that belongs in Kiko's report is Vacuoles in plants are much larger than those in animals.

Answer:

sedimentary rock

Explanation:

fossils are most commonly found in sedimentary rock. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remnants. Often these fossils may only be visible under magnification.

Why do you think species remain in a stage of stasis?
dmitriy555 [2]
<span>The answer is A. A stable ecological niche leads to the absence of selection pressures, which in turn causes species to remain unmodified or in stasis. This can be simplified with an example: If there are just enough lions on an island and just enough buck for both species to survive without the lions starving or the buck being killed off, neither of the species would have to adapt to survive because their predator-prey relationship is stable. This means that they can continue to live in this state of stasis or equilibrium. </span>
