Answer – B (Electrons)

When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.

A cell has undergone determination to become an epithelial lung cell. If it is transplanted to a leg muscle, what do you think w
olasank [31]

Answer:

Change occur in form and structure of the cell.

Explanation:

The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.

Iodine is a yellowish solution. A starch solution is white. A starch solution turns purplish-black in the presence of iodine. If
cupoosta [38]

Answer:

The correct answer will be- the color change will be observed and the solution will turn purplish-black.

Explanation:

Iodine test is performed to test the presence of the carbohydrates mainly starch.

The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.

In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.

A biologist marked 200 mice, by putting leg bands on them, out of a forest containing an unknown number of mice. The marked mice
Fofino [41]

Answer: The estimated population is 1250 mice

Explanation: The method use was marked and recapture, in which individuals are marked in the first capture and after some time biologist trap a new group of individuals that can be or not marked

Whit this data is possible to estimate the size of a population applying the Peterson method but is important to make some considerations such as:

1. All indivuals have the same probability to be capture

2, The population remain constant in terms of birth and death rate.

Taking this into account, the formula that allows to determine the size of the population is:

N=CM / R  

where N is the size of the population, C is number of indivuals trapped in recapture, M is number of individuals marked in the first capture and R is the number of marked animals trapped in recapture

In this case:

N = 250 * 200 / 40 = 1250
