A cell is a membrane-bound structure that occurs as a functional independent unit of life (such as in unicellular organisms, e.g. bacteria, protozoa, etc.), or as the structural or fundamental unit in a biological tissue specialized to perform a particular function in multicellular organisms (e.g. plants and animals).
Answer:
Dark color absorb more photons and thus gets more hot
Explanation:
Dark color is dark b/c it absorbs different wavelengths of light (think about little photons of light vibrating slighting differently) .This means it absorbs a lot of photons which makes it warmer.
If a thing is white, that means it reflects all lights and absorbs none. Thus, since it does not absorb photons (little packets of energy which is light), the house does not get warm.
False. Respiration is providing oxygen for the cells and getting rid of the carbon dioxide, while digestion is transforming food into usable energy.
Answer:
Prokaryotes or unicellular organisms, without a nucleus, are categorized in two different kingdoms: Eubacteria and Archaebacteria or simply, bacteria and archaea, respectively. Sometimes these two kingdoms are also clubbed together as Monera. Unicellular organisms with a nucleus are part of the kingdom Protista.
Answer:
Explanation:
B-cells engulf an antigen by endocytosis.
<u>Endocytosis:</u>
The process by which cell takes up external materials by fusing them with plasma membrane is called endocytosis.
After engulfing the antigen, B-cells become sensitive to the pathogen.
