Biologists sometimes divide living organisms into two groups: autotrophs and heterotrophs. these two groups differ in ________.

1 answer:

8 0

Their source of carbon. Autotrophs obtain their carbon from inorganic sources such as from atmospheric carbon dioxide. Examples of autotrophs include plants, and euglena ( a protist).
Heterotrophs on the other hand, obtain their carbon from organic sources such as other organisms. Examples of heterotrophs include all secondary consumers, and decomposers.

Both klebsiella pneumoniae and streptococcus pneumoniae avoid phagocytosis by releasing a-b toxins that kill leukocytes.

Kobotan [32]

This is a false statement.

Klebsiella pneumoniae and Streptococcus pneumoniae are two bacteria who are encapsulated, that means that they are surrounded by an envelope. This capsule is critical to their pathogenicity since it protects them from the phagocytes of the human immune system. Certain proteins located on the surface of their capsule prevent the phagocytic cell from adhering to the bacteria and engulfing it.

Solar panels convert light energy from sunlight into electrical energy. What material is most likely used in solar panels, and w

Sever21 [200]

Answer: Solar panels are made up of silicon cells. This because silicon has high ability for conduction and this make it to be able to convert sunlight into electricity. It is in solar cells has impurities and great chemical properties which make it to be to convert sunlight to electricity.

Silicon

Explanation:

Silicon is an element with atomic number 14, it is a non metal and crystalline solid. It has blue grey metallic lustre. Silicon is made with impurities in solar cells and has special chemical properties to convert sunlight into electricity. It is a semiconductor, a material that can act as a conductor and insulator.

When light interact with silicon cells, it make electrons to be in motion and initiate the flow of electricity, it is called photovoltaic effect.

Silicon alone is not used, it used with metal casing and wiring to ensure proper electric flow.

What type of organism uses cellular respiration for their cellular energy needs

ololo11 [35]

Answer: Organisms from all kingdoms of life. For example; <u>bacteria, archaea, plants, protists, animals, and fungi, can use cellular respiration.</u>

Explanation: <u>All organisms carry out cellular respiration in the mitochondria of their cells. They take in oxygen to convert glucose to usable ATP. In the process carbon is released as a waste. Plants and algae carry out photosynthesis in the chloroplasts of their cells.</u>
