I believe you are referring to Nucleic acids.
Answer:
Correct answer is A. "making future predictions about plant behavior "
Explanation:
The most important part of the question is "overcrowded area" which leads to the future concerned scenario of modern societies. We know that, in future, the supply of resources/nutrients will be limited and thus we want to develop sustainable practices. For this, scientists often carry out the experiments where the organisms are forced to live/grow in a crowded area and then we understand how each individual responds in the presence of limited resource supply. In this experiment, I perceive that the scientist is doing a similar kind of study for a specific plant which will help him assess the future concerns of growth and development for that species as well as its interaction with the environment.
Answer:
nucleic acids.
Explanation:
The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.
Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.
Answer:
Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic.
