Carbon dioxide goes into the atmosphere and is absorbed by plants along with water, to produce oxygen an plant structures, whether cellulose, starch, or sugar-which are then eaten by mammals.
Stresses on the Earth's system include incomplete combustion of carbon to produce carbon monoxide. The burning of fossil fuels such as oil and carbon, And also the presence of excess ozone in the upper atmosphere.

Answer:
1. sperm cells: cell has a flagellum for movement
2. smooth muscle: cells have an elongated shape (tapered at each end)
3. Squamous epithelium: cells are close together
4. Human red blood cells: cells are circular
5. Squamous epithelium cells are thin and flat, with irregular borders
6. Human red blood cells: cells are anucleate (without a nucleus)
7. smooth muscle: longest cell
Explanation:
- <em>Sperm cells</em>: Active and morphologically specialized cells. They characterize as having an elliptic head mostly occupied by the nucleus, and a tail of about 55 micrometers that moves impulsed by a motor dynein protein that uses ATP energy.
- Smooth muscle cells: Fusiform cells. Long and tapered at the extremes. Located in organs and viscera, and in vessel walls, where involuntary maintained slow contractions are needed. Although they are the longest cells, their length depends on the organ where they are located. They might reach up to 500 microns.
- Squamous epithelium cells: The wide and length of the cells supere their height. Some of them suffer a process of keratinization from being exposed to dehydration and touch.
- Red blood cells: Red blood cells or erythrocytes are biconcave disks-shaped, with no nucleus, and very small. These are flexible cells that might move along in the smallest capillaries. Hemoglobin provides the typical red color. The red blood cell size and number vary among species.
Answer: Carbon is one of the most important chemical, non-metallic element that is considered to be the fundamental unit, making up the organic life. Carbon is present in almost all the living beings existing on earth.
Carbon plays a significant role in the carbon cycle. It transfers from plants to the animals or organisms as one consumes the plants, vegetables that are around us and further released into the atmosphere from the bodies of the living creatures during exhalation. This continuous transformation of carbon from one place to another is regarded as the carbon cycle.
It is abundant and can easily react with various elements.
Answer:
Due to the law of segregation each allele is it's own entity and always has an equal chance of being passed on to the next generation. This means that regardless of whether the allele it will be passed on in the same frequency
