Answer:
The temperature of the surrounding air increases when the atmospheric CO2 level increases.
Explanation: Carbondioxide gas is a very important gas in the environment but high amount of it cause damage to the organisms.
Carbondioxide gas is also called greenhouse gas because it has the ability to absorb or trap heat energy when the solar radiation goes into the space after hitting the earth surface. If the concentration of carbondioxide gas is increased, more heat energy will be trapped and thus increase occurs in the temperature of the atmosphere which results in global warming.
B. Mutation, because mutations are random alleluia changes that change future generations

Answer: Option D.
Explanation:
The process of bone thickening starts with the formation of a template of the hyaline cartilage diaphysis from chondrocytes. Due to developmental signals the bone matrix begins to calcify. This calcification allows the prevention of nutrition diffusion into bone matrix and opens the cavities in diaphysis cartilage. Blood vessels enters into the cavities and osteoblasts and osteoclasts modifies calcified cartilage matrix into spongy bone. Osteoclasts allows the break down of spongy bone and forms a medullary cavity in diaphysis. Irregular connective tissue forms a periosteum (covers compact bone) around the bones and allows the attachment of bone to tissues, tendons, and ligaments. The bone then continues to grow and get thick.
Hence, the correct option is D.
An enzymatic weight-gain supplement claims to help users digest all carbohydrates in fruits and vegetables. Cellulase enzyme is present.
<h3>What is cellulase ?</h3>
Cellulase (systematic name 4—D-glucan 4-glucanohydrolase) is any of a number of enzymes that catalyse cellulolysis, the breakdown of cellulose and some related polysaccharides, and is primarily produced by fungi, bacteria, and protozoans.
Endohydrolysis of (14)-D-glucosidic linkages in lichenin, cereal -D-glucan, and cellulose
The term is also applied to any naturally occurring combination or complex of numerous such enzymes that break down cellulosic material sequentially or cooperatively.
Cellulases convert the cellulose molecule into shorter polysaccharides and oligosaccharides, as well as monosaccharides (or "simple sugars") like -glucose. Because it makes a key plant component usable for food and use in chemical reactions, cellulose breakdown has significant economic significance. The 1,4-D-glycosidic bonds in cellulose, hemicellulose, lichenin, and cereal -D-glucans are hydrolyzed in this particular process. Compared to the breakdown of other polysaccharides like starch, the breakdown of cellulose is particularly challenging because the molecules of cellulose bind tightly to one another.
