Answer: C. both biotic and abiotic factors

Explanation:

An ecosystem can be define as biotic community where living beings or biotic  factors of the environment interacts with the non-living components or abiotic factors of the environment. This interaction is necessary for sustaining life on earth as living beings are dependent upon the non-living physical environment for completing their life cycles.

Biotic factors includes the plants, animals, microbes, and other living beings. Abiotic factors includes the soil, water, air and sunlight.

have fewer branches than astrocytes. are star-shaped cells. are branched extensions off of a neuron. are small, phagocytic cells
Varvara68 [4.7K]

Answer:

Neuroglia - the supporting cells of the nervous system

Oligodendrocytes - fewer branches than astrocytes

Dendrites - branched extensions off of a neuron

Astrocytes - star-shaped cells

Microglia - small, phagocytic cells in the central nervous system

Explanation:

The given cells in the question are cells of different types of neuroglial cells that are astrocytes, microglia, oligodendrocytes are different types of neuroglial cells. The nervous systems are supported by this Neuroglia.

As the name indicates Astrocytes are star-shaped cells and carry many branches whereas, Dendrites are the smaller, but higher in numbers, projections of the neuron cell body. It has also axon projection bind to the cell body.

• Microglia are phagocytic cells that protects  thenervous system

Each round of the citric acid cycle begins when the four-carbon molecule oxaloacetate is converted to the six-carbon molecule ci
Verdich [7]

Answer:

The added carbon is supplied by acetyl CoA and the 2 eliminated carbons are released as CO2.

Explanation:

TCA cycle or citric acid cycle occurs in the mitocondrial matrix.

           The ist step of TCA cycle deals with the formation of citrate molecule bt the addition of Acetyl CoA with oxaloacetate. The acetyl CoA is a 2 carbon compound formed from pyruvate by the catalytic activity of pyruvate dehydrogenase .

          The 2 eliminated carbons are released as carbon di oxide or CO2.The CO2 molecule is eliminated during the formation of alpha ketoglutarate from isocitrate .The second CO2 molecule is eliminated when alpha ketoglutarate is converted to succinyl CoA.

describe the similarities and differences between aerobic cellular respiration and anaerobic cellular respiration
Lena [83]

Aerobic cellular respiration takes place in the presence of oxygen and anaerobic cellular respiration takes place in the absence of oxygen.

Similarities:

  • As a beginning molecule, glucose is used in both aerobic and anaerobic respiration, which is a similarity. The substrate is what you see here.
  • Additionally, both aerobic and anaerobic respiration results in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
  • In both situations, food is oxidized and energy is liberated.

Differences:

  • Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen.
  • Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration.
  • Compared to anaerobic respiration, aerobic respiration produces more energy.
