Red blood cells have _________ and generate energy ________.
mitochondria; anaerobically
no mitochondria; anaerobically
mitochondria; aerobically
no mitochondria; aerobically
None of the above
Answer:
no mitochondria; anaerobically
Explanation:
Red blood cells have no mitochondria and generate energy anaerobic. So, the answer would be B. You can easily eliminate A. and C. because they mention that blood cells have a mitochondria, but they don’t.

where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?
Answer:
They use the glucose they have stored from previous photosynthesis reactions.
Explanation:
The dark reaction takes place external to the thylakoids. The energy from ATP and NADPH is used in this process to fix carbon dioxide (CO2).
What is light-independent/dark reactions?Carbon fixation, reduction, and regeneration are the three stages that make up the Calvin cycle, which is another term for the dark reactions that take place during photosynthesis.
The stroma of the chloroplast is the location where the light-independent process, also known as dark reactions or the Calvin-Benson cycle, is carried out. Carbon-based molecules are formed through a chain of chemical events that begin with carbon dioxide. The production of ATP and NADPH during the light-dependent process supplies these processes with the energy they need to proceed.

where are unmyelinated nerve fibers surrounded by schwann cells?
Schwann cells without myelination are seen in the peripheral nervous system (PNS).
Myelinating Schwann cells and non-myelinating Schwann cells are the two different kinds of Schwann cells. One kind of neuroglial cell is the Schwann cell. Nerves are helped and supported by neuroglial cells. Nerve impulses can be sent at speeds of about 270 miles per hour thanks to the ability of Schwann cells to speed up the process.The myelinating Schwann cell coils around nerve axons with large diameters. The myelinating Schwann cell creates the neurilemma, a lipid base membrane, as it loops itself around the nerve fiber. The myelin sheath develops from the neurilemma.However, unlike a hotdog bun that encircles a hotdog, the non-myelinating Schwann cell does not form myelin; instead, it permits thin nerve fibers to rest along, within, and on top of the non-myelinating Schwann cell. Non-myelinated nerves often have slower nerve transmission.Learn more about the Schwann cells with the help of the given link:

Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms. Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.
why did the early atmosphere not have much oxygen?
Answer:
The oxygen did not build up in the atmosphere for a long time, since it was absorbed by rocks that could be easily oxidized (rusted). To this day, most of the oxygen produced over time is locked up in the ancient "banded rock" and "red bed" rock formations found in ancient sedimentary rock.

What is the conversion factor from km. to ft.? If Joe traveled 12 kilometers, how many feet did he travel?
Answer:
The distance traveled by Joe in feet is 39,372 ft:
Explanation:
The conservation factor from km to Ft is 1 km = 3280.84 feet.
* In order to convert the value-form km to ft then we multiply the given value of the length by 3281.
*We are given that:
*Distance traveled by Joe = 12km
*Distance in feet = 12×3281
*Distance in feet = 39,372 ft
**Thus, the Distance traveled by Joe in feet is 39,372 ft.
The conversion factor from kilometers to feet is 3280.84 feet/kilometer. This means that there are 3280.84 feet in every kilometer.
So, if Joe traveled 12 kilometers, he traveled 12 * 3280.84 = 39370.08 feet.
1 kilometer = 3280.84 feet
12 kilometers = 12 * 3280.84 feet = 39370.08 feet
Therefore, Joe traveled 39370.08 feet if he traveled 12 kilometers.
