The correct answer is letter A. Connective tissues can be liquid, solid, or semi-solid. They are supporting fibers that are found within the body that give support to the musculoskeletal organ systems and they also bind all other tissues together.
The discovery of fossils in graves and in archaeological digs suggest that humans were already collecting unusual shaped rocks or minerals in prehistoric times. ... Minerals were used for cosmetic purpose but also for medical use and therefore collected in the field.
Answer: hope this helps
Explanation: A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:
A+BC \rightarrow AC+B
In this general reaction, element Ais a metal and replaces element B, also a metal, in the compound. When the element that is doing the replacing is a nonmetal, it must replace another nonmetal in a compound, and the general equation becomes:
Y+XZ \rightarrow XY+Z
Yis a nonmetal and replaces the nonmetal Zin the compound with X.
Metal Replacement
Magnesium is a more reactive metal than copper. When a strip of magnesium metal is placed in an aqueous solution of copper(II) nitrate, it replaces the copper. The products of the reaction are aqueous magnesium nitrate and solid copper metal.
\text{Mg}(s)+\text{Cu(NO}_3)_2(aq) \rightarrow \text{Mg(NO}_3)_2 (aq) + \text{Cu}(s)
This subcategory of single-replacement reactions is called a metal replacement reaction because it is a metal that is being replaced (copper).
Answer:
When oxygen is scarce cellular pyruvic acid is converted to Lactic acid
Explanation:
In the absents of the oxygen, certain organisms such as yeast can convert pyruvate into carbon dioxide
False. The subunits are dependent on the cell itself, and they cannot survive on their own.
