arsen [322]

Answer:

see in explaination

Explanation:

Density (D) is a quantity defined as mass (m) per unit volume (v): D = m ÷ v. Since these three quantities are related, you can find one of them if you know the other two. This is more helpful than it sounds because density is often a known quantity that you can look up, assuming you know the composition of the material.

Calculations are straightforward for solid objects, but things get more complicated for liquids, where density changes with temperature, and for gases, for which density is dependent on temperature and pressure.

ASAP please help!!! Please please please please ​<br>I'll give you Brainliest!!!!!!
Natasha_Volkova [10]

Answer:

See the answer below

Explanation:

From the graph, the concentration of salt solution where the number of burst red blood cells equals the number of intact ones is 0.40 g/100 cm3<u>.</u>

<em>At this concentration, the percentage of burst cells is 50, meaning that the remaining 50% of the cells in the experiment remained intact.</em>

The totality of the concentrations of all the salt solutions used is:

0.30+0.35+0.40+0.45+0.50 = 2 g/100 cm3

Thus, the percentage of salt solution concentration when the number of red blood cells that burst is the same as the number of red blood cells that do not burst equals;

          0.40/2 x 100% = 20%

Why are the cells produced by meiosis considered gametes?
BigorU [14]
Gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).
