Answer:

Mutation is a process where the genomic composition or genotype of a species undergoes some changes due to different environmental factors. The change on the gene can cause an abnormal body function in a species. The abnormality cause the species harder to survive in an environment they use to be and affect their survival and reproduction rate. The mutated species that can't adapt to the environment will be easily removed from the population.

Mutation affect a species ability to survive and reproduce. Mutations can expand the life span of a species by keeping them hidden from predators which would also increase reproduction. If exposed to other wildlife, those numbers could decrease.

in an experiment 3.425g of lead oxide was reduced to form 3.105g of lead the empirical formula of the lead oxide is?​
Romashka-Z-Leto [24]

Answer:

Pb3O4

Explanation:

According to this question, 3.425g of lead oxide was reduced to form 3.105g of lead in an experiment. Since lead oxide contains both lead (Pb) and oxygen (O) element,

Mass of lead oxide = 3.425g

Mass of lead = 3.105g

Mass of oxygen = (3.425g - 3.105g) = 0.320g

Next, we convert each mass value to mole by dividing by respective molar mass

Pb = 3.105g ÷ 207.2 = 0.0149mol

O = 0.320g ÷ 16 = 0.02mol

Next, we divide each mole value by the smallest (0.0149)

Pb = 0.0149mol ÷ 0.0149mol = 1

O = 0.02mol ÷ 0.0149mol = 1.342

Multiply each ratio value by 3 to get:

Pb = 1 × 3 = 3

O = 1.342 × 3 = 4.026

The whole number ratio, approximately, of Pb and O is 3:4, hence, their empirical formula is Pb3O4.

Melissa is interested in her family tree and how her family has changed over its many generations. Melissa probably more closely
tresset_1 [31]

Answer: A Confucian

Explanation:

In the year 2005, the Guinness Book of World Records recognized the Confucius genealogical line as the longest family tree in history. They have a record of 86 generations over 2,500 years. Confucius (551 to 479 BCE) is believed to have about 3 million descendants all over the world.

So the interest Melissa has in her family tree and also wanting to know how her family has changed over its many generations probably suggests that Melissa more closely resembles a Confucian.

If temperature is increased , the number of collisions per second
AfilCa [17]

Answer: when the temperature is increased, the number of collisions per second increases.

Explanation:

the rate of collisions and the temperature is directly proportional. If the  energy of the gas particles is boosted by using the temperature, the chances of the particles bumping into each other due to the high energy increases, thus increasing the number of collisions. This also increases the rate of reaction. Thus when temperature is increased the number of collisions also increases.
