Ques: Q: Dna replication is the first step in what process for both eukaryotic and prokaryotic cells? Read this paragraph and choose the correct option from the provided answers: 1. The first step in eukaryotic cell division, as it is in prokaryotic cell division, is DNA replication. As you can see in Figure below , each chromosome then consists of two identical copies. The two copies are called sister chromatids. They are attached to each other at a point called the centromere. Choices: - cell death - cell growth - cell transfer - cell division A:
Ans: cell division

Ques: Q: Coal, oil and natural gas are types of what formed from the remains of once living organisms? Read this paragraph and choose the correct option from the provided answers: Coal, oil and natural gas are all fossil fuels formed from the remains of once living organisms. Choices: - living fossils - fossil compounds - crop fuels - fossil fuels A:
Ans: fossil fuels

Ques: Q: The oxygen atom in a water molecule pull the electrons away from the hydrogen atoms which leads to an unequal distribution of what? Read this paragraph and choose the correct option from the provided answers: This model shows the arrangement of oxygen and hydrogen atoms in a water molecule. A water molecule has a bent or angular (non-linear) shape, with an angle of about 105. The nucleus of the oxygen atom attracts electrons more strongly than do the hydrogen nuclei. As a result, the middle part of the molecule near oxygen has a negative charge, and the other parts of the molecule have a positive charge. In essence, the electrons are "pulled" toward the nucleus of the oxygen atom and away from the hydrogen atom nuclei. Water is a polar molecule, with an unequal distribution of charge throughout the molecule. Choices: - nitrogen - atomic mass - orbits - charge A:
Ans: charge
