Answer:
The correct answer is - C. It is composed of different kinds of tissues.
Explanation:
An organ is a part of the body that is composed of different types of tissues that form a structure and vascularisation, and capable of the development of a physiological function.
The mesentery is a structure that connects the loops of the small intestine which is made up of the different types of tissue to perform a various functions and is not a part of a particular organ system.

Explanation:
In biochemistry, two biopolymers are antiparallel if they run parallel to each other but with opposite directionality (alignments). An example is the two complementary strands of a DNA double helix, which run in opposite directions alongside each other.
Explanation:
Genetic variation in offspring during sexual reproduction is caused by
- crossing over
- independent assortment
- randomized fertilization
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
- crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
- independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
- randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

Answer: Proteins
Explanation:
Proteins are one of the most plentiful naturally-grown molecules in living systems and possess the most distinctive extent of duties of all macromolecules. The purposes of proteins are highly distinct for 20, unlike chemically different amino acids that develop large chains, plus the amino acids can occur in any method. Proteins may be architectural, regulatory, contractile, or shielding; they may work in transportation, storage, or membranes; or they may be poisons or enzymes. An instance of the function of proteins: proteins can work as enzymes or hormones. Enzymes made by living cells are catalysts in biochemical reactions and are usually proteins.
A conclusion is a final answer backed by evidence. An inference is a reasonable guess.
