Answer:
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane
Answer:
Do the organism's colls have nuclei?
Explanation:
Protists represent eukaryotic organisms whose cells contain a nucleus and organelles delimited by membranes, whereas Archaea and Bacteria are unicellular prokaryotic organisms that lack a cell nucleus, in which the genetic material (chromosome) is localized in a part of the cytoplasm named nucleoid. Eukaryotic organisms include protists, animals, plants, fungi, and most algae. Most protists are unicellular, although there are species that are multicellular.
To solve this question you need to know the specific heat of the object, which is water. The specific heat of water is 1 calorie/gram °C = 4.2<span>joule/gram °C. The energy needed would be:
Q= c*</span>m*ΔT
Q= 1 calorie/gram °C * 250 g * (85-25°C )
Q= 15000 calorie= 63000J
