Answer:
If you go to a local store, and get scar cream, like stretch mark cream, that would help a lot.
Explanation:
Hope this helped! :)
Please don't hurt yourself :(
Certain elements are required in large quantities, and others are required in small amounts by the body, but both are essential for the survival of the cells. The cells which are required in large amounts are called as macronutrients, while the ones required in small quantities are called as micronutrients, or trace elements.
Hence, the answer is trace elements or micronutrients.
Answer:
potential energy
Explanation:
Work changes potential and kinetic energy. When you throw a ball, you transfer energy to it and it moves. By doing work on the ball, you can give it which is the energy of motion. Any moving object has some kinetic energy.
The answer is that a unicellular organism would swell and burst.
In a hypotonic solution the water concentration of the cell's cytoplasm is lower then that of the hypotonic solution. If unicellular organism is exposed to a hypotonic solution, the water from the solution will enter the organism by the process called osmosis. The aim is to balance water concentration on the inside and outside of the organism. But, that water entering the cytoplasm of the cell will make pressure on the cell membrane. If the excess water cannot be removed from the organism, it will swell and burst.
1.
The first prokaryotic cells (the less complex in its organization and with no organelles involved in membranes) evolved about 3.5 billion years ago. Therefore, the correct answer is D. 3.5 billion.
2.
Then, some prokaryotic cells evolved to use the sunlight to produce energy and release O2 into the atmosphere about 2.8 billion years ago. Therefore, the correct answer is C. 2.8 billion.
3.
After that, the prokaryotic cells evolved to cells with organelles bounded by membranes, and then the eukaryotic cells evolved about 2.5 billion years ago. Therefore, the correct answer is B. 2.1 billion.
4.
A long time after that, aproximately 650 million years, the first life composed of an organism with multiple cells evolved. Therefore, the correct answer is A. 650 million.
