Yes people are eating them and selling the skin.
Answer:
7.8 moles are needed.
Explanation:
Given data:
Mass of oxygen produced = 125 g
Number of moles of mercury oxide needed = ?
Solution:
Chemical equation;
2HgO → 2Hg + O₂
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 125 g/ 32 g/mol
Number of moles = 3.9 mol
Now we will compare the moles of oxygen with mercury oxide.
O₂ : HgO
1 : 2
3.9 : 2×3.9 = 7.8 mol
Answer:
The fill in the blanks are as follows:
a-unicellular prokaryotes that live in dust are Eubacteria.
b-unicellular eukaryotes that live in pond water are Protista.
c-multicellular eukaryotes that live all over the planet and consume food are Anamalia.
d-unicellular prokaryotes that live in volcanic ash and other inhospitable environments are Archaebacteria.
e-multicellular eukaryotes that have cell walls and are heterotrophic are Fungi.
f-multicellular eukaryotes that have cell walls and are autotrophic are Plantae.
Explanation:
By looking for the definitions of the different types of eukoaryotes and prokaryotes, the fill in the blanks are correctly completed.
A ribosome is a cell organelle. the function of a ribosome is like a micro-machine for making proteins. the ribosomes is composed of special proteins and nucleic acid. it is also formed from two sub units, locking together its function are to translate the encoded information from the cell nucleus provied by the messenger.
Answer: a. Excesses are eliminated from the kidneys.
Explanation:
A fat-soluble vitamin can be dissolved in fats and oils. They are absorbed along with fats in the diet from the intestinal lumen using the same mechanisms used for absorption of lipids. Upon absorption, <u>these vitamins enter the lymph vessels</u> before making they go into the bloodstream. In most cases, fat-soluble vitamins must be coupled with a protein in order to be transported through the organism. <u>This means they are solubilized and transported by carrier proteins </u>to exert their actions.
By last, since fat-soluble vitamins can not be dissolved in water,<u> they are not readily excreted. So they can accumulate in fatty tissues</u> to toxic levels if taken in excess.
