Explain how a species can evolve through natural selection. What is natural selection in your own words?
Answer:
Natural selection is process that allow organism that has suitable attributes with its environment, to thrive (grow in population), to survive, and to pass its genetic information to the next generation (children, grand children).
Explanation:
For example: in an island, a male giraffe, and a female giraffe produce giraffe children with various attributes. Some giraffe children have short neck, and some have long neck.
Giraffe eats the leaves of Acacia tree, and Mimosa tree. Many acacia tree and tall mimosa tree in that island, are tall trees, so a giraffe that has long neck can reach that tall tree, eat the leaves, survive, and grow to adult stage.
A giraffe that has short neck, can only eat small quantity of leaves, then it suffers, can not grow, becomes skinny, and unable to compete with other giraffe finding its mate. It can't pass its genetic information to the next generation, and becomes extinct.
That's how natural selection, in above case, an island with a lot of tall acacia trees and mimosa trees selects giraffe with long neck to survive.
The next interesting follow up question would be how a male giraffe and a female giraffe produce various kind of giraffe children? The answer is a pair of chromosome become a single chromosome in giraffe sperm, and in a giraffe eggs. But that question and its answer are beyond the scope of the original question.

Create a three-paragraph proposal of three changes/laws you would make in order to combat three issues. Explain how each change will help save water and reduce our planet's increasing temperature.
(dont answer if you dont know)
Not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.
How to save water and protect the planet?Not washing the sidewalks, there is a lot of water loss when people wash the sidewalks, looking for other ways to clean the neighborhood is necessary.
Taking baths efficiently, not spending much time in the shower, water will be saved, and new measures to anthropize rivers will not be necessary.
Consume locally produced products, avoiding gas emissions with transport, thus preventing a large amount of fuel from being burned.
With this information, we can conclude that not washing sidewalks, taking quick showers and consuming local products are changes that will help to save water and reduce the increase in the temperature of our planet.

Choose TWO locations below (A, B, C) and provide a two-sentence weather forecast for that location. Your forecast must include Wind direction, general wind speed (high, moderate, low) general temperatures (cold, cool, mild, warm, hot), and sky conditions(precipitation/stormy, sunny cloudy).
Climatic maps use isobars to read the barometric pressure and to determine climatic patterns in different areas. Points B and C are described below.
How to interpret a weather map?
Meteorology is determined mainly by barometric pressure, which is the pressure exerted by atmospheric air on the Earth's surface. It is measured in millibars, Mb.
Barometric pressure systems are closely associated with weather patterns, which is why it is used to create climatic maps.
⇒ Pressure:
An average pressure system at sea level ⇒ 1013 Mb.A high-pressure system ⇒ air descends ⇒ Good weather and few clouds ⇒ 1030 Mb.A low-pressure system ⇒ air ascends ⇒ Hot ascending air condense and forms clouds. Bad weather, storm probabilities ⇒ 1000 Mb.⇒ Isobars:
Used to read barometric pressures in climatic mapsThese are curve lines that indicate the areas with the same barometric pressures.They are arranged in concentric figures, one inside the other one. The smallest one indicates the pressure center.- High-pressure center is indicated with an H
- Low-pressure center is indicated with an L
Isobars are significant when determining wind speed and direction.
⇒ Wind direction:
In High-pressure center is indicated with clockwise arrows in the northern hemisphere
In Low-pressure center is indicated with counterclockwise arrows in the northern hemisphere
Winds tend to move from high pressure areas to low pressure areas.
⇒ Wind speed:
The closer isobars are between each other, the stronger and faster the wind is.
⇒ Front types:
Cold front ⇒ represented by blue lines with blue triangles pointing in the direction of the front movement. When a cold front passes by, there are high probabilities of strong winds and severe precipitations. Hot front ⇒ represented by red lines with red semi-circles pointing in the direction of the front movement. There is an increase in temperature as the front approximates. There might be precipitations. Occluded front ⇒ represented by purple lines with red semi-circles and blue triangles pointing in the direction of the front movement. It forms when a cold front overtakes a warm front. There might be storms.
Point C
Near a Low Pressure system Isobars: close to each otherMass of light, warm and wet air. Since the air is light, it tends to ascend, creating clouds and rains.Air pressure: low -around 1000 Mb-Weather conditions: cloudy, rainy, stormy.Wind direction: counterclockwise in the northern hemisphere.Wind speed: high to moderateTemperature: warm or hotA hot front is approximatingPoint B
