is the step in science when you do an experiement
1. Make a question
2. background research
3. create a hypothesis
4. test/experiement
5. analyse
6. conclusion
7. share - because when you share it to others, others can repeat your experiment and prove is it true or false or is it really science
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
Explanation:
If its outermost electron shell is filled.
Answer:
concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
Explanation:
given
- concentration of calcium ion in blood = 1.21 mmol/L
- Concentration in mEq/L = Concentration in mmol/L x valence of the ion
- The valence electron is the number of electron present in the outermost shell. Calcium belongs to the group2 elements also known as the alkaline earth metal, and their valence electron is 2.
- Hence, concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L
where mEq/L = milliequivalent per liter
Answer: Plants or the sun
Explanation:
The sun gives energy to the plants which get the most but since the sun isnt an organism I would say plants.
