Answer:
Photosynthesis provides most of the oxygen that humans and animals breathe. Chlorophyll uses sunlight energy to transform the carbon dioxide and water into oxygen and carbon-based compounds such as glucose, a sugar that helps plants grow.
For macrophytes, photosynthesis in reproductive structures decreases the energy and carbon costs of reproduction to the rest of the plan, which might be more important for iteroparous rather than semelparous organisms.

How did the geography of Mesopotamia contribute to the development of early civilization there? Be sure to include three supporting details in your response.
Answer:
Trade Routes. Mesopotamia's rivers and location in central Asia supported extensive trade routes. ... This allowed Mesopotamia to access resources not native to its region, like timber and precious metals. In turn, Mesopotamia developed key aspects of civilization, like a token system to keep trading records
The Tigris and Euphrates frequently flood, making the area around them particularly fertile and perfect for raising food crops. It was therefore a perfect location for the Neolithic Revolution, also known as the Agricultural Revolution, which got underway around 12,000 years ago.
What was the geography of ancient Mesopotamia?The area between the Euphrates and Tigris rivers, both of which originate in the Taurus Mountains, is referred to as Mesopotamia. The area has a semi-arid climate, with a sizable desert in the north giving way to a 5,800 sq. mile region of marshes, lagoons, mud flats, and reed banks in the south.
In addition to being one of the first regions to develop agriculture, Mesopotamia served as a nexus for the Indus Valley and Egyptian civilizations. As a result, it became a linguistic and cultural melting pot that influenced writing, technology, language, trade, religion, and law in a significant way.

What is Earth?Earth is a planet present in the solar system having the existence of life. This is the only planet on which life is possible due to living conditions that ensure the availability of water which is important for survival.
The climate on Earth was warm at the start of the Carboniferous Period. The equatorial regions were typically hot and moist while glaciers eventually formed at the poles. The climate on Earth fluctuated between glacial and interglacial periods.
The temperature cooled and dried out during the Carboniferous rainforest's collapse. As the Earth underwent a brief but intense glacial period, this is represented in the geological record.

Earth's axis of rotation is tilted at an angle of 23.5 degrees. What is one change you would see on
Earth if its axis was not tilted?
Earth's axis of rotation is tilted at an angle of 23.5 degrees. If the earth's axis was not tilted we wouldn't experience a different season.
What is one change you would see on Earth if its axis was not tilted?The primary reason for the seasons is the tilt of the Earth's axis. If Earth were flat, a person standing in one position on the surface would experience the same amount of daylight and solar warmth throughout the year. There would be no seasonal variations in temperature; the equator would always be hot, and the poles would always be frigid.
The region close to Earth's equator would still be hotter than the region surrounding the poles. However, due to Earth's tilt, the Northern Hemisphere is directed more directly at the Sun on one side of the orbit (as seen on the left side of the picture above).

What is the discharge of a stream with a width of 4 meters, depth of 0.8 meters and an average velocity of 0.12m/sec?
A 4.35 m3/sec
B 0.384 m3/sec
C 3.08 m3/sec
D none of the above
Considering Stream Discharge analysis, the discharge of a stream with a width of 4 meters, depth of 0.8 meters, and an average velocity of 0.12m/sec is "0.384 m3/sec."
What is Stream Discharge?Stream Discharge is the geographical term used to describe the product of stream velocity, times depth, times width.
The formula for Stream dischargeThe mathematical formula for stream discharge is the velocity (V - length of travel per unit of time such as feet/second) × depth of the water (D - unit of length) × width (W of the water - units of length).
Thus, in this case, we have 4m×0.8m×0.12m/sec => 0.384 m3/sec
Hence, in this case, it is concluded that the correct answer is option B. "0.384 m3/sec."
