Explanation:
Tarbuck, Earth's crust is made up of several elements: oxygen, 46.6 percent by weight; silicon, 27.7 percent; aluminum, 8.1 percent; iron, 5 percent; calcium, 3.6 percent; sodium, 2.8 percent, potassium, 2.6 percent, and magnesium, 2.1 percent
About 29% of Earth's surface is land consisting of continents and islands. The remaining 71% is covered with water, mostly by oceans but also lakes, rivers and other fresh water, which all together constitute the hydrosphere.

Earth.
Almost 99% of the minerals making up the Earth's crust are made up of just eight elements. Most of these elements are found combined with other elements as compounds.
Answer:
The cell will swell.
Explanation:
The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.
This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.
Answer:
Im pretty sure its A if I read that right.
Explanation:
hope this helps
Answer:
True
Explanation:
Meiosis is a type of cell division that occurs in gametic cells. In this cell division, one cell is divided into four cells and the chromosome number is reduced to half therefore it is also called reduction division.
During meiosis crossing over occurs between homologous chromosomes that allow the exchange of genetic material between them that results in the formation of genetically unique daughter cells.
In spermatogenesis during the first meiosis division, the homologous chromosomes get separated into two daughter cells reducing the chromosome number by half and during second meiotic division sister chromatids separate into two more cells. Therefore four genetically different cells are generated.
B is the correct answer because the density it the salts would make the water increase therefore sink faster
