Answer in your OWN WORDS!
A gardener discovers that her prize hydrangeas have turned from pink to blue. What can you say about the soil in which the flowers are growing?
Generally speaking, acidic soil, with a pH lower than 6.0, yields blue or lavender-blue hydrangea blooms. Alkaline soil, with a pH above 7.0, promotes pinks and reds. With a pH between 6 and 7, the blooms turn purple or bluish-pink. To lower your pH, add garden sulfur or aluminum sulfate to your soil.
The secret's in the soil
Let’s look at why pH is so important.
Most major plant nutrients are more accessible at a pH of 6 to 6.5. A pH that is too high or too low can keep plants from absorbing nutrients from the soil. The nutrients are unavailable — or not absorbable — to the plant because of soil's chemistry. This problem can manifest itself in a variety of ways, but in the case of hydrangeas, the bloom color changes.
Color variation in hydrangeas is due to the presence or absence of aluminum compounds in the flowers. If aluminum is present, the color is blue. If it is present in small quantities, the color is variable between pink and blue. If aluminum is absent, the flowers are pink.

3.How are climate and weather different?
4.How can you depict annual precipitation at a site location, like a local airport?
5. What is the transformation of water vapor to liquid water droplets in the air?
Climate is different from the weather. Climate is the long term weather condition and weather is short term atmospheric condition. The annual precipitation is report is depicted as graphical data. Transformation of water vapor to liquid droplets in air is called condensation.
What is climate?Climate in a region is the long term weather exists there and which will be characteristic for that region. Weather is forecasted for a day or a particular time, reporting the short term atmospheric condition. Climate of a locality depends on the landscape there, local winds etc.
The annual precipitation report determined by the summation of monthly precipitation data and which in turn obtained by the summation daily precipitation for each month and it is depicted graphically to analyse.
The transformation of water vapor to liquid droplets in the air is called condensation. The gaseous molecules of the water vapor condense together to form the liquid droplets.

Explanation:
Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

A sturdy plant is placed in an airtight, transparent container. The entire experiment is then weighed. For 10 days, the plant grows inside the container. After 10 days, the container is weighed again. The air inside the container is pumped out and carefully analyzed.
What is true about the air inside the container and the mass of the experiment?
-The air is richer in carbon dioxide. The mass of the experiment has not changed.
-The air is richer in oxygen. The mass of the experiment has changed.
-The air is richer in carbon dioxide. The mass of the experiment has changed.
-The air is richer in oxygen. The mass of the experiment has not changed.
PLEASE HELPPPPP
Plants release oxygen by photosynthesis and consume carbon dioxide for it. Thus the air after the experiment will be rich in oxygen but the mass of the container dose not change.
What is photosynthesis?Photosynthesis is a biochemical process by which green plants produce glucose and oxygen with the aid of light energy. Combination of water and carbon dioxide results in the formation of glucose and molecular oxygen.
By photosynthetic reaction, the air will be rich in oxygen and some fraction of carbon dioxide in the atmosphere will be consumed by plants. That's why this process is said to be an event in carbon cycle.
The mass of the container in the experiment does not change, whereas, the air collected will contain more oxygen than before which is released by the plants.

List the five physical phase changes of matter and give one example for each.
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

Interphase: the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.
