Answer: B

Explanation: The beetles would be able to use their genetic color to learn how to adapt to the environment and hide from predators.

The statement, that describes the genetic color variation within the beetle population helps them to survive is "the color variation helps them avoid predators."

Genetic variations that can exist in a human population include skin color, hair color, dimples, freckles, and blood type. Human skin tone is a classic changeable characteristic that is regarded to be adaptive. Natural selection can result in major changes in the appearance, behavior, or physiology of individuals in a group in a matter of generations.

Meiosis and sexual reproduction combine various alleles in novel ways to generate genetic variety once new alleles emerge. Because of natural selection, green beetles outnumber red beetles. Color diversity can involve camouflage, and beetles could utilize their genetic color to learn how to adapt to their surroundings and hide from predators.

Because this feature has a genetic foundation, the surviving beetles have progeny of the same hue. Brown coloring, which permits the beetle to have more offspring, becomes increasingly prevalent in the population.

Hence the correct option is B.

Answer: The best way to promote the process are:

--> Add a bit of solid as a seed crystal.

--> Scratch the bottom of the flask gently with a stirring rod.

Explanation:

A crystal growth is seen is SUPERSATURATED solutions which contains more solute than it can normally dissolve at that given temperature. It is usually very UNSTABLE and capable of releasing the excess solute if disturbed, either by shaking or seeding with a tiny crystals.

Crystallization can be used for the separation of two salts with different solubilities as well as for purification of a soluble salt that contains insoluble solid impurities. Recrystallization improves the validity of the process. Crystallization can be initiated by:

--> Scratching the bottom of the flask gently with a stirring rod: scratching initiates crystallization by providing energy from the high-frequency vibrations.

--> Adding a bit of solid as a seed crystal: Seed crystals create a nucleation site where crystals can begin growth.

Answer:

6.64

Explanation:

so moles

[tex] \frac{number \: of \: \: particles \: }{6.02 \times {10}^{23} } [/tex]

then do =4.01×10^24/6.02×10^23

you get the answer as 6.6445 u only need to write the answer to

Answer:

H =2; I = 2; J = 2  

Explanation:

Carbon is element 6 in the Periodic Table.  

Start at element 1 (H) and count from left to right until you reach element 6 (C).

You get the electron configuration

C: 1s² 2s²2p².

Thus,

H =2; I = 2; J = 2

Explanation:

first blank 4

second blank 3

third blank 2

Explanation:

Find moles first

moles = number of particles/ 6×10^23

= 7.52 ×10^25 / 6×10^23

=125.33

calculate molar mass

(1×14) +(3×1) =17

convert to mass

mass= moles × molar mass

=125.33 × 17

=2130.67g

This is a pretty big value usually it's smaller but I'd assume it's because the number of particles was large.

Answer:

V = nRT/P

Explanation:

The ideal gas law states that

PV=nRT

where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T= temperature

P V = n R T

to get V on its own, divide both sides of the equation by P

V = (nRT)/P
