What cells in living organisms are diploid

Pavlova-9 [17]

Question

<em>what cells in living organisms are diploid?</em>

Answer:

<em>Most mammals are diploid organisms, which means they have two homologous copies of each chromosome in the cells. In humans, there are 46 chromosomes. In most diploid organisms, every cell except for gametes will be diploid and contain both sets of chromosomes.</em>

Hope this helps!

A piece of metal with a mass of 611 g is placed into a graduated cylinder that contains 25.1 mL of water rising the water level

djyliett [7]

Answer:

The answer is

<h2>2.64 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume} \\$

From the question

mass = 611 g

volume = final volume of water - initial volume of water

volume = 256.7 - 25.1 = 231.6 mL

The density of the metal is

$density = \frac{611}{231.6} \\ = 2.638169257...$

We have the final answer as

<h3>2.64 g/mL</h3>

Hope this helps you

A mysterious compoud with the chemical formula MX (Ksp 1.27x10-36) is present in two different solutions. What is its molar solu

qwelly [4]

<u>Answer:</u> The molar solubility of MX is $2.54\times 10^{-36}M$

<u>Explanation:</u>

We are given:

$K_{sp}(MX)=1.27\times 10^{-36}$

The chemical equation for the ionization of MX follows:

$MX\rightleftharpoons M^+(aq.)+X^-(aq.)$

S S

The expression of $K_{sp}$ for above equation is:

$K_{sp}=S\times S$ ......(1)

The chemical equation for the ionization of $M_2SO_4$ follows:

$M_2SO_4\rightleftharpoons 2M^+(aq.)+SO_4^{2-}(aq.)$

0.25M 0.5M 0.25M

Total concentration of cation from both the equation is:

$[M^+]=0.5+S$

As, $K_{sp}(MX)$ , so S is also very very less than 1 and can be easily neglected.

So, $[M^+]=0.5M$

Putting values in equation 1, we get:

$1.27\times 10^{-36}=0.5\times S\\\\S=2.54\times 10^{-36}M$

Hence, the molar solubility of MX is $2.54\times 10^{-36}M$

Which compound(s will not form a yellow precipitate when treated with excess iodine in the presence of naoh?

Novosadov [1.4K]

For example:

5Cl₂ + I₂ + 12NaOH = 10NaCl + 2NaIO₃ + 6H₂O

Na₂S₂O₃ + 4I₂ + 10NaOH = 8NaI + 2Na₂SO₄ + 5H₂O
