Answer:
The three types of rocks are Igneous, Sedimentary, and Metaphoric.
Explanation:
<em>Igneous</em> rocks are formed out of melted rocks deep inside the Earth. A distinguishing unique characteristic is that they are hard.
<em>Sedimentary</em> is formed from layers of sand, silt, dead plants, and animal skeletons. A distinguishing unique characteristic is that they are easy to crumble.
<em>Metaphoric </em>are formed when minerals change through heat and pressure underground. Two distinguishing unique characteristics are that they may have many layers and are noticeably hard.
Each hemoglobin contains four iron-containing heme groups and four polypeptide chains. Four oxygen molecules can bind each Hb molecule.
True, four hemoglobin chains will contain one heme group, which will bind exactly one oxygen molecule. Since hemoglobin contains four globin chains with four heme groups, four oxygen molecules can bind to one hemoglobin molecule.
<h3>What is
hemoglobin ?</h3>
Blood-carrying protein hemoglobin (haemoglobin BrE) is derived from the Greek word haîma and the Latin term globus. (/hi-m-lo-bn, h-mo-/ abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein found in the tissues of some invertebrates as well as the red blood cells (erythrocytes) of practically all vertebrates (with the exception of the fish family Channichthyidae). The blood's hemoglobin transports oxygen from the respiratory system, including the lungs and gills, to the rest of the body (i.e. tissues). There, the oxygen is released, allowing aerobic respiration to take place and produce energy for an organism's metabolic processes. Every 100 mL of blood in a healthy person has 12 to 20 grams of hemoglobin.

Answer:
E1: Pyruvate dehydrogenase, TPP, oxidative decarboxylation reaction
E2: Dihydrolipoyl transacetylase, Lipoamide and Co-enzyme A, transacetylation reaction.
E3: Dihydrolipoyl dehydrogenase, FAD and NAD+, oxidation reaction
Explanation:
Pyruvate dehydrogenase is a multi-enzyme complex with 5 co-enzymes and 3 apo-enzymes:
Pyruvate dehydrogenase (E1) , which uses thiamine pyrophosphate (TPP) as as co-enzymes to catalyze oxidative decarboxylation of pyruvate to hydroxyethyl-TPP.
Dihydrolipoyl transacetylase (E2): which uses lipoamide and coenzyme A as co-enzymes to catalyse the transacetylation from TPP to Lipoamide to form acetyl lipoamide.
Dihydrolipoyl dehydrogenase (E3) which uses FAD and NAD+ as co-enzymes to catalyze the oxidation of lipoamide
Answer:
Both are multicellular (plants have different cells for the leaves and the stem, animals have skin cells, brain cells etc so they are called multicellular).
Plants are autotrophic - they make their own food (glucose) by photosynthesis
Animals are heterotrophic - they eat other organisms, cannot make their own food.

Answer:
Explanation:
One of the earlier experiments that confirmed DNA and not proteins as genetic material was conducted by Alfred Hershey and Martha Chase
Hershey and Chase experiment showed the genetic material of virus is DNA not protein. Their experiments demonstrated that Phage are composed of DNA and protein, when phage infect bacteria, their DNA enters the host bacterial cell but not protein before infection
Hershey and Chase experiment prove that DNA is the hereditary material.
From chargaff base pairing rule, the ratio of purine to pyrimidine is a cell is 1:1. Since adenine pair with thymine and cytosine pair with quanine, this means the percentage of adenine will equal the percentage of thymine.
%A = %T and %G = %C.
%A + %T + %G + %C =100
If a DNA contains 8% adenine, therefore the percentage of thymine is 8%
8% + 8% + %G +%C = 100%
16% + %G +%C = 100%
%G +%C = 100%-16%
%G +%C = 84% = 84%/2= 42%
Since %G = %C
Then %G = 42%, %C = 42
