The best answer is D.
Carbohydrates get rapidly digested and are quickly converted to glucose . Once glucose levels in the blood rise, insulin that is produced by the pancreas begins to remove excess glucose from the blood and stimulates the liver to turn it into a type of starch called glycogen, which is stored in the liver and muscles.
However the body can only store a limited amount of glycogen so the excess glucose is stored as body fat (adipose tissue). This is the process of putting on weight.
Multi cellular organisms are composed of many cells whereas unicellular organisms are composed of single cell. Multicellularity is indeed a progressive attribute of evolution where cells form tissue which forms organ and then organ system and finally an organism. Both multi cellular and unicellular organisms has advantages and disadvantages of their own. One of the main disadvantage of multi cellular organisms is that due to such a complex composition and functioning they require a large amount of energy for their maintenance and survival. Different organs and system require a huge amount of energy when it comes to comparison with unicellular organisms. A large amount of energy is also wasted in all these life processes. Though multi cellular organisms can survive in a variety of environmental conditions but then also their survival is difficult than any unicellular organism.
C. Dinosaur footprint as it is the only body part that is stated in the choices.
Hope this helps :)
Coccus-shaped bacteria can be found in pairs, chains, squares of four, cubes of eight, or grape like clusters. More specificially, this type of bacteria found in pairs is called diplococcia, in chains is called streptococci, in squares of four is called tetrads, in cubes of eight is called sarcinae, and in grape like clusters called staphylocci.
