Answer:

Ca(OH)2 (aq)

Explanation:

<em>The base in the reaction would be Ca(OH)2 (aq).</em>

A base is a substance which when dissolved in water, releases $OH^-$ as the only negative ion. A base is also a substance that donates electrons and accept protons in a reaction.

Ca(OH)2 in aqueous solution will ionize thus:

$Ca(OH)_2 (aq) --> Ca^{2+} (aq) + OH^- (aq)$

In a reaction involving an acid, the hydroxyl ion donates its electron and accept proton.

$H^+ + OH^- --> H_2O$

What is a distinction that can be drawn between macroevolution and microevolution?

nikitadnepr [17]

<span>Microevolution refers to changes in the genetic pool of a species population. The changes in the genes (probably gene and allele frequencies) are observed over short time periods hence are small changes. This is in comparison to macroevolution that observes huge changes over longer time periods in the population that warrant that the new populations is considered to be a new species</span>

Drag the correct word from the left into the sentence on the right to complete each sentence. In anabolic reactions that involve

kkurt [141]

Answer:

The correct matches are:

In anabolic reactions that involve the synthesis of a large molecule from smaller precursor molecules, NADH and ATP are consumed when they provide the needed electrons or energy.
In catabolic reactions that involve the breakdown of a molecule into smaller subunits, such as glucose to pyruvate, NADH and ATP are produced.
In the reaction Pyruvate +NADH-Lactate +NAD, pyruvate is being reduced.
In the reaction Pyruvate NADH-Lactate +NAD, NADH is being oxidized.

Explanation:

Being involved in synthesis, anabolic reactions require energy in the form of energy storing molecules such as NADH and ATP. Anabolic processes utilize energy produced by the catabolism of complex compounds.
Catabolic processes produce energy or energy storing compounds by breaking down complex substances into simpler ones. All steps of cellular respiration are catabolic processes since they generate energy in the form of ATP or energy yielding molecules such as NADH and FADH2.
Anaerobic respiration takes place during intense physical activity due to which adequate oxygen does not reach the cells. Insufficient oxygen shuttles the pyruvate molecules produced by glycolysis into the lactic acid pathway that reduces pyruvate into lactic acid.
Since, NADH is donating its H+, it is being oxidized to NAD+.

Someone help me with 3-6

kifflom [539]

3. C6H12O6
4. Organic compounds are compounds made up of carbon that are typically linked to hydrogen (H), oxygen (O) and/or nitrogen (N). Glucose has C, H and O which makes it (and any other carbohydrate) organic.
5. Sugar (glucose) is in a lot of foods - bread, rice, pasta, potatoes....
6. On the label it will have the number of calories in the food (per serving!) - this is how much energy there is in that amount of the product.

Answer:

Egg white and amino acid solution.

Explanation:

Egg white and amino acid solution are the two foods that are used for building of body parts because they have proteins in them that is responsible for the building of muscles of in human body. There are two components of egg i.e. white and yellow part. White is the proteinic part whereas yellow parts having fats and other nutrients. Amino acid solution has amino acids which is considered as the building block from which protein is made.
