<u>Question</u>:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

years of decay
quantity of energy
number of stable atoms
amount of material that has not decayed

<u>Answer</u>:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

<u>Explanation</u>:

The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over $\frac{1}{16} th$ of the sample remained. In percentage it is 6.25%

<h2>Correct answer is option "a"</h2>

Explanation:

Succession is a directional non-regular total change in the sorts of plant species that involve a given region through time. It includes the procedures of colonization, foundation, and annihilation which follow up on the taking an interest plant species.
Most successions contains various stages that can be perceived by the assortment of species that overwhelm by then in the succession start when a zone is made in part or totally without vegetation due to an unsettling influence.
Some basic instruments of unsettling influence are fires, wind storms, volcanic emissions, logging, environmental change, extreme flooding, sickness, and irritation. Succession stops when species organization changes never again happen with time, and this community is said to be a peak network.
So, the correct answer is option a "primary succession"

After cell division (mitosis) how does the genetic code of the newly

Harrizon [31]

Answer:

Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.

Explanation:

Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:

G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.

S is the period of DNA synthesis, where cells replicate their chromosomes.

G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.

M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.

4. A soda can has a volume of 0.35 liters and before opened its internal pressure is 30 psi. What

777dan777 [17]

The volume of the gas expansion is 0.71 liters.

<h3>Boyle's law</h3>

Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.

P₁V₁ = P₂V₂

where;

P₁ = 30 psi
V₁ = 0.35 liters
P₂ = 1 atm = 14.7 psi

The volume of the gas expansion is calculated as follows;

$V_2 = \frac{P_1 V_1}{P_2} \\\\V_2 = \frac{30 \times 0.35}{14.7} \\\\V_2 = 0.71 \ Liters$
