The winds that move from cold upland areas into lower elevations under the influence of gravity are described as katabatic winds. They are also called downslope winds, or gravity winds.
These winds carry high-density air from a higher elevation (<span>mountains, plateaus, and hills )</span>down a slope under the force of gravity. The katabatic winds<span> occur at night, when the highlands radiate heat and are cooled.</span>
Answer: 3
Explanation:
All elements in group 3 have 3 levels of energy.
Na (sodium) has 3 valences the inner has 2 electrons, the middle has 8 electrons and the outer has 1 electron.
This will continue across the group 3 adding one more electron to the outer valence until Ar (argon).
Remember the Octet rule of 8..?
Answer:
The box will not move because balanced forces are acting on it.
Explanation:
According to Newton's first law of motion, an object will remain in its state of rest or motion along a straight line unless acted upon by an unbalanced force.
An unbalanced force is an individual force acting on any side of an object which is not balanced by a force of equal magnitude acting in the opposite direction.
From the image, two forces of equal magnitude of 10 N are pulling the 100 kg box in opposite directions. Since the two forces, 10 N each are pulling the object in opposite directions, they are balanced forces. Therefore, the box will not move because balanced forces are acting on it.
Answer:
Sexual reproduction occurs from the fusion of male sperm cell with female egg cells. Due to this fusion, fertile zygote is formed which turns into a new organism.
Explanation:
The sperm cell of male and egg cell of female are haploid in nature i. e. half number of chromosome. When two haploid cells combine together, it forms diploid cell i. e. double number of chromosomes. The organism which is formed from sexual reproduction have diploid cell.
It should be every answer except: some traits are passed together from generation to generation
