Answer:
All secondary consumers will die because they will lose their food source
Answer:
Sound waves required a medium.
Explanation:
In space, there is only vacuum hence no any medium for sound wave travel.
Since sound waves are mechanical waves, they require a material medium such as air, hence no sound transmission.
A 4
B 6
C Be
D 10
E 22
F Ne
Explanation:
From the given table, we can simply complete the given table by identifying the meaning of each column header.
- Number of protons in an atom is the number of positively charged particles in the nucleus of the atom. Protons are positively charged particles in an atom.
- The number of neutrons are the number of neutrally charged particles occupying the nucleus of an atom.
- Atomic number is another term for the number of protons in an atom.
- Mass number is the sum of protons and neutron in an atom.
- The symbol of an element is used represent a particular atom.
Mass number = number of protons + number of neutrons
Atomic number = number of protons = number of electrons in atoms.

First step is to get the mass of water molecule in grams:
From the periodic table:
molar mass of hydrogen is 1
molar mass of oxygen is 16
molar mass of a water molecule = 2(1) + 16 = 18 gm
Now, to convert the gm into amu, all you have to do is multiply the gm you got by Avogadro's number as follows:
mass of water molecule = 18 x 6.22 x 10^23 = 1.1196 x 10^25 amu which is approximately 1 x 10^25 amu
A scientist should study the side effects of her new treatments if he wants to make advances in the treatment.
Explanation:
- A scientist when creating any advancement in any treatment its the duty of the scientist to find the side effects of her new treatments.
- When a patient is suffering from skin cancer and the scientist want to upgrade the techniques for treating it , its the duty of the scientist to look after certain factors.
- The first factor should be the scientist should study the side effect first and after that the scientist should make certain tests . After making tests the scientist should study the success rate and then the scientist should move for the treatment.
