Answer: Oxygen, Beryllium, Lithium, & Fluorine
Explanation:
theoretically it might not be the answer be
We are diploid organisms thus require two sets of chromosomes. In order to ensure the zygote is a diploid (has 2 sets of chromosomes) the gametes must be haploids (has 1 set of chromosomes) as two gametes join to make a zygote.
Having half the set of chromosomes also ensures that the offspring receives half of its chromosomes from its father and half from its mother. This becomes very important as to ensure there is genetic diversity in the offspring, both the fathers and mothers genes are needed.
Answer:
No
Explanation:
Some have different things in it
Answer:
Calculate the mass percent of a potassium nitrate solution when 15.0 g KNO3 is dissolved in 250 g
of water.
2. Calculate the mass percent of a sodium nitrate solution when 150.0 g NaNO3 is dissolved in 500 mL
of water. Hint: 1 mL water = 1 g water
3. Calculate the weight of table salt needed to make 670 grams of a 4.00% solution.
4. How many grams of solute are in 2,200 grams of a 7.00% solution?
5. How many grams of sodium chloride are needed to prepare 6,000 grams of a 20% solution?
Mass Percent = Grams of Solute
Grams of Solution X 100%
100%
Grams of Solute = Grams of Solution X Mass Percent
= 26.8 grams NaCl
= 670 grams X 4.00%
100%
100%
Grams of Solute = Grams of Solution X Mass Percent
= 154 grams solute
= 2,200 grams X 7.00%
100%
100%
Grams of Solute = Grams of Solution X Mass Percent
= 1,200 grams NaCl
= 6,000 grams X 20.0%
100%
