Answer:
A: Discovery of DNA as the genetic material
Explanation:
DNA is the genetic material and stretch of DNA that codes for a specific protein is called as gene. Discovery of DNA as genetic material provided the physical proof of Mendel's factors that were responsible for transmission of genetic traits in his experiment.
Discovery of DNA as genetic material also established that genetic variations among individuals of the species as described by Darwin are due to minor differences in their DNA molecules.
Hence, discovery of DNA as genetic material led to acceptance of both Mendel's law and Darwin's theory.
1. Every framework has their doing in arranging our body capacities. Regardless of whether it's the heart drawing blood through our body and lungs boosting oxygen and discharge carbon dioxide. Endocrine gives the correspondence through hormones; secrete their hormones directly into the bloodstream and uses blood vessels as information channels. It stimulates sebaceous glands whereas the sex hormones affect the distribution of subcutaneous fat. In addition, the endocrine system regulates metabolism, growth and development of tissues, and sexual functions. The endocrine and integumentary systems correlate with the sense organs, which react to heat, cold, vibration, texture, and pressure. When such senses are produced by the sense organs they react to the senses and send the information to the endocrine system and therefore hormones are released which causes the mood swings according to the situation. For example, it reacts to the body with pleasure or discomfort related to the senses.
2. Atomic solution and radiology bring the procedures which analyze and regard maladies by utilizing radiopharmaceuticals as the pictures of body organs or envision certain infections. This involves radiations which are used to diagnose, treat and prevent certain diseases. In the present era, these procedures are the best and hence the most effective life-saving techniques. They are safe and painless as compared to other surgical treatments involving operations. They don’t even require anesthesia. Both of these techniques are used in diagnosing a disease and monitoring the course of an illness. They are then used for the treatment of any disease as well. Diseases such as cancer or heart disease are therefore treated by radiation technology.<span>

The BEST example of technological design is researching a disease resistant corn hybrid.
This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.
Explanation:
The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.
A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.
A solution having lower concentration of solute than the cell cytoplasm is called the hypotonic solution.
The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.
A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.
A cell placed in hypotonic solution will undergo endosmosis of water so it will gain water and its mass will increase.
