Answer:
A
Explanation:
Answer is A because, production of gametes happens in meiosis. So, the first splitting of one cell into two daughter cell occurs in telophase I and then in each of these daughter cells in meiosis II those sister chromatids separate into full fledged chromosome and each daughter cell splits into two different cells. So at end you have 4 new non-identical daughter cells.

Explanation:
Answer:
The steel plow and barbed wire
Explanation:
It was in 1837 when John Deere, a blacksmith from Illinois invented a steel mouldboard plough that was strong enough to cut through the stubborn roots of the prairie grasses. This invention turned millions of acres of prairie land into fields for arable crops and grazing ground for huge herds of domesticated cattle. The starving Indians who were displaced resorted to slaughtering the bison in 1872 to 1874 that resulted in the decrease of its population from 7.5M animals to about 750 only.
Atomic number Z = 8
as atomic number is equal to number of protons So, there are 8 protons in the oxygen 16 and oxygen 18
And number of protons is equal to number of electrons so there are 8 electrons in both oxygen 16 and oxygen-18.
Number of neutrons = Mass number - Atomic number
so, number of neutrons in oxygen-18 = 18 - 8 = 10
and number of neutrons in oxygen-16 = 16 - 8 = 8
Answer:
The scientist must complete the experiment, evaluate the results and disclose his conclusions.
Explanation:
If the scientist wishes to find conflicting data in a widely accepted theory, he must first establish a scientific experiment using all the steps of the scientific method. It is important for the scientist to complete the entire experiment so that he can evaluate the results and reach concrete conclusions about whether there is, in fact, conflicting data in the theory. The results should generate conclusions that must be disclosed regardless of whether the cinetist's hypotheses are proven or not.
The scientific method is a set of rules that guide the execution of a scientific experiment.
