Answer:
1 closer
2 24hours
3 tidal bulges
4 in a straight line
Explanation:
Tides have been the effect of the sea with the gravitational pull of the sun and moon.
1. Earth’s tides are affected by the gravitational pull of the Sun and the Moon, but mainly the Moon because the Moon is closer to the earth.
In spite of high pull of the Sun, the distance of moon from earth results in increased effect of moon gravitational pull than Sun.
2. Each day, each coastal region on Earth experiences two high tides and two low tides in every 24 hours time period.
The daily tides has been resulted at the coast with the moon revolution around the earth's rotation.
3. This is because the gravitational attraction of the Moon creates tidal bulges on two opposite sides of the planet.
The effect of the moon gravitational force results in the bulging or the pulling force to the sea, resulting in the diurnal tides.
4. Two spring tides occur monthly, when the Moon is in its new and full phases. During these phases, the Moon and Sun are oriented at a right angle measuring 90 degrees which gravitation pulls the water on Earth in the same direction, creating a large tidal range.

Georgia has many invasive species including the gypsy moth, kudzu, boll weevil, and tropical spiderwort. All of these have led to the destruction of many local ecosystems, and have cost Georgian's millions of dollars. What characteristic of Georgia makes it a place where invasive species often end up? A) more forest space than any other state B) shrinking population leaving room for other organisms to live C) the lack of a variety of species opens the door to invasive ones D) hundreds of miles of highway, a very large airport, and many ports for ships and cargo
Answer:
C.
Explanation:
Invasive species are the non-native species in a particular area, society or environment causing more havoc than good. Invasive species are introduced into the environment through many means which might be intentional and which might not.
One of the reason behind the presence of invasive species in Georgia is to augment the native specie present in Georgia at that time for instance, one of the invasive species mentioned in the question that is "kudzu" was introduced to the environment in Georgia as specie for controlling erosion.
Although some invasive species were introduced into Georgia by mistake, some invasive species were also introduce because of the need for new Specie in the environment.

Which process is represented by this diagram?
Answer:distillation
Explanation:
The process represented by the diagram is chromatography.
What is chromatography?
Chromatography is a separation technique used to separate components present in a mixture.It makes use of two phases the stationary phase and mobile phase .
Stationary phase is a phase in which the mixture components to be separated is loaded. Mobile phase is a phase which is run over the stationary phase so as to enables components of mixtures to separate.
Separation of components is based on the principle that components of mixture which are soluble in mobile phase travel large distances over stationary phase while those which are insoluble or less soluble travel less distances over stationary phase.
For every component which is separated, a Rf value can be calculated which is simply ratio distance traveled by solute divided by distance traveled by solvent front.

arrange 0.35 kilograms 9.4 grams and 5 grams to smallest to largest
Answer:
5 grams < 9.4 grams < 0.35 kilograms
Explanation:
Kilograms (Kg) and grams (g) are both units of measurement for MASS quantity. However, these units are not the same as they vary in magnitude. The kilograms is bigger unit of measurement than the grams. 1000grams makes 1kilograms.
According to this question, 0.35 kilograms 9.4 grams and 5 grams are to be arranged in ascending order i.e. from smallest to largest. First, we need to change all the units to the same.
We change 0.35kg to g
Since 1000g = 1kg
Then, 0.35kg = 0.35 × 1000
= 350g.
Rearranging the values, we have:
5 grams < 9.4 grams < 0.35 kilograms

A student accidentally left a bottle of ammonia unclosed in the corner of a laboratory
After a few minutes the entire laboratory smelled of ammonia.
Which process has occurred?
A
Brownian motion
B
Diffusion
с
Evaporation
D
Distillation
Answer:
Evaporation
Explanation:
because the ammonia is left unclosed
The smell of ammonia has been spread from a corner to entire room by the process of diffusion. Thus, option B is correct.
Ammonia has been the liquid compound with the formula [tex]\rm NH_4[/tex]. It has a pungent smell. Ammonia has been used in several synthesis reactions, and in various industrial processes.
The diffusion has been the process of transfer of molecules from higher concentration to lower concentration. The smell of ammonia has been spread in the entire laboratory from a corner.
The ammonia molecules in the bottle are at higher concentration while there has been lower concentration of ammonia in the environment. With the process of diffusion there has been the transfer of ammonia molecules in the environment.
Thus, diffusion has been responsible for spreading the smell of ammonia in the laboratory from a corner. Thus, option B is correct.
