Answer:
Part A: Proteins are made from amino acid monomers. There are 20 different types of amino acids which make up all the proteins of the body. The amino acids are made up of a carbon atom which is joined to an amino group, a carboxyl group and a variant group, known as R. Nucleic acids are made up of 5 carbon sugar, phosphate group and nitrogenous bases. Hence, nucleic acids are made up of nucleotides.
Part B: Protiens are important molecule which carry out various functions of the body. They are involved in regulation of various body process. Some proteins are involved in the transportation of various molecules. Other type of proteins are involved in various immune functions and hence protect the body. For example, antibodies are proteins which defend the body against pathogens.
Nucleic acids are involved in the storing and expressing of genetic information. They also direct the body for protein synthesis.
Answer:
c. accidental removal of the parathyroid glands during surgery
Explanation:
Parathyroid gland is found closely situated at the back of the thyroid gland in the human neck region. Regulation of serum calcium levels in the body is a major function of the parathyroid gland through the secretion of a hormone called parathyroid hormone or parathormone.
During the surgery conducted to remove the thyroid gland, it is very likely that the parathyroid glands were accidentally damaged or removed. This most likely led to the non--secretion of parathormone, which is responsible for secretion of calcium in the body, when calcium levels drop.
Answer:
b
Explanation:
Genetic Organization of Prokaryotes Aids Fast Generation Times. Compared to eukaryotes, prokaryotes usually have much smaller genomes. On average, a eukaryotic cell has 1000 times more DNA than a prokaryote. This means that less DNA must be replicated (copied) with each cell division in prokaryotes
Answer: NADPH and ATP
Explanation:
The mechanism of photosynthesis can be divided into two phases, light reaction, and carbon fixation. During the light reaction, photosynthetic pigments absorb radiant energy and undergo a series of photochemical reactions and convert the trapped energy into chemical energy which is stored in the form of NADPH and ATP. These two compounds constitute the assimilatory power. Light reaction is light dependent and it takes place in the grana of the chloroplast.
Answer:
evolution
Explanation:
For example, scientists believe that monkeys have evolved to become humans.
This clearly has happened over many millions of years.
Monkeys look really different from humans (don't you think!?).
This was just a random example that came to my head.
Hope this helps.
