Answer:
Option (C).
Explanation:
Reading frames represent a way of reading the sequence of nucleotides in a DNA or RNA molecule into a set of non-overlapping, constitutive triplets.
These triplets are known as genetic codes or codons. There are total 64 codons, out of which 61 code for particular amino acids and three codons provide stop signaling.
So, if a reading frames change in a RNA molecule, it will lead to change in codon sequence and formation of a completely different peptide.
Thus, the correct answer is option (C).

Brain can process and store lot of information. Large brains means large heads, which makes childbirth more difficult and painful for human mothers.
Explanation:
A larger brain provides better performance. human brain size increases rapidly. Human brains are larger, more complex brains which enabled humans of this time period to interact with each other and with their surroundings in different ways.
The prefrontal cortex is slightly a larger part in the human brain. Humans have the largest cerebral cortex. It is a sheet of brain cells that folds itself multiple times in order to fit inside the skull. It enables us to process everything we see and hear and think.
The right answer is ghrelin levels are relatively low.
Ghrelin is a hormone secreted by the cells of the stomach, ghrelin triggers the sensation of hunger. The release of ghrelin is done when the body needs a new supply of energy and therefore to feed. The rate of ghrelin decreases following the meal: the hunger disappears.
This hormone is the subject of many studies: inhibiting its action may help to fight against obesity. At least for obesity due mainly to overeating.
Answer:
- The six essential nutrients are vitamins, minerals, protein, fats, water, and carbohydrates.
-The digestive system converts the foods we eat into their simplest forms, like glucose, amino acids or fatty acids.
- The function of the excretory system to remove wastes from the body.
-The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.
-The excretory system works with the endocrine system to help maintain homeostasis. Chemical messengers called hormones signal the kidneys to filter more or less water or salt, depending on the levels of water and salt in the body.
