It is true that earth is consist of 70% water. However it is still a problem that in the near future, their might be a water shortage that will happened. This is because now mostly of our water sources are no longer clean. Our water are polluted and when time will come water will be very pricey
<span>The answer is : Both have true necks, while eusthenopteron has no neck. </span>We know that tiktaalik is more closely related to acanthostega than it is Ichthyostega eusthenopteron because Tiktaalik and Acanthostega both have true necks while eusthenopteron has none.
Explanation:
B. serves as the control center of the cell and contains the cell's genetic information
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
Further Explanation:
A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:
- may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
- separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins

The answer is A
Explanation:
It is logical because the balloon lets the student see how much gas is released in the reaction. the balloon inflates with invisible air the student will normally not see.
Eukaryotes are the<span> type of cells that typically do not contain cilia or a flagella.
The ones that do are called prokaryotes.</span>
