Second and fourth are true because the shape is changed since liquid does not have a shape and the particles are more strong bonded on solids
Answer:
Explanation:
Colour of objects. The colours we see are the wavelengths that are reflected or transmitted. For example, a red shirt looks red because the dye molecules in the fabric have absorbed the wavelengths of light from the violet/blue end of the spectrum. Red light is the only light that is reflected from the shirt.
D
B makes no sense
C makes so sense as variation causes natural selection so if they were all the same natural selection wouldnt happen
A isnt right
the answer is D as the organisms must have some variation in order to be different enough and less/more well adapted to their habitat in order for the less well adapted ones to die- and the more well adapted ones to live and pass on advantageous alleles/genes
Answer:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
My answer uh might not be the one you're looking for or isn't correct ✌
Explanation:
Answer:
Cellulose is held by beta 1,4-glycosidic bonds making it linear while Glycogen is held by an alpha 1,4-glycosidic bond making it highly branched.
Explanation:
Cellulose and Glycogen are both carbohydrate polysaccharides formed from glucose monomers. According to the question, cellulose is a tough, fibrous, and insoluble (in water) polymer found to play a structural role in plants' cell wall while Glycogen is another polymer obtained from muscle or liver and disperses readily in hot water to make a turbid solution.
Although these two polysaccharides (cellulose and glycogen) are linked by (1, 4)-glycosidic bonds but the glucose monomers in CELLULOSE are linked by a beta 1,4-glycosidic, hence, making it a straight or linear polymer
GLYCOGEN, on the other hand, is linked by an alpha 1,4-glycosidic bond making it an highly branched polymer. This structure is responsible for the different physical properties of the two molecules.
