it wont et e answer i will edit it in the commetns
Answer: Option E
Explanation:
During conducting the experiment, it was performed in control conditions. In this case the top predators were removed.
There were limited number of organism left at the place which compete with each other for the same resources.
Mussel and Barnacle were the two species left there which feed on the same resources for their needs. This is the reason there was loss of diversity.
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
The splitting in of oxygen to form water. At the end of the chain, electrons are transferred to molecular oxygen,which splits in half and takes up H plus to form water.
Answer:
B. 160 has 8 neutrons, whereas 180 has 10 neutrons.
Explanation:
The proton of an element is also known as the atomic number. Oxygen has an atomic number of 8 and also a proton of 8. Neutron is however calculated by the subtraction of the mass number from the atomic number (proton).
This results in 160 having 8 neutrons because the mass number(16) is subtracted from the atomic number to give 8 neutrons, whereas 180 has 10 neutrons as a result of the mass number 18- the atomic number(8) to give 10.
