An insertion mutation results in one or more DNA nucleotides being inserted into existing DNA.
According to the kinetic molecular theory, the pressure of a gas in a container will increase if the "number of collisions with the container wall increases".
<u>Option: A</u>
<u>Explanation:</u>
Pressure is characterized as force acting by area per unit. It is triggered by gas molecules bombarding on the container walls. Kinetic molecular theory suggests that gases are made up of large numbers of small particles with continuous movement. Here there are elastic collisions between gas particles and between particles and container walls. There are no forces of attraction among them because of the large spaces between the gas particles. The gas temperature relies on the particle's average kinetic energy.
Answer:
third
Explanation:
because it's the right distance for life to utilise the sun's power energy
Answer:
1.63ₓ10⁻⁶ g of U
139.03 g of H
0.385 g of O
141.8 g of Pb
Explanation:
In first place, we need to convert the number of atoms to moles, as we know that 1 mol of anything occupies 6.02×10²³ particles
Therefore:
4.12×10¹⁵ atoms of U . 1 mol / 6.02×10²³ atoms = 6.84×10⁻⁹ moles of U
8.37×10²⁵ atoms of H . 1 mol /6.02×10²³ atoms = 139.03 moles of H
1.45×10²² atoms of O . 1 mol /6.02×10²³ atoms = 0.0241 moles of O
4.12×10²³ atoms of Pb . 1 mol /6.02×10²³ atoms = 0.684 moles of Pb
Moles . Molar mass = Mass (g)
6.84×10⁻⁹ moles of U . 238.03 g/mol = 1.63ₓ10⁻⁶ g of U
139.03 moles of H . 1 g/mol = 139.03 g of H
0.0241 moles of O . 16 g/mol = 0.385 g of O
0.684 moles of Pb . 207.2 g/mol = 141.8 g of Pb
The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.
