Answer:
DNA
Explanation:
DNA is directly related to the physical and physiological characteristics of our body and other living beings, in addition to being the main molecule responsible for heredity. In eukaryotic organisms, the DNA molecule is found in the cell nucleus and in organelles called mitochondria. In prokaryotic organisms, on the other hand, this material is dispersed in the cell's cytoplasm.
DNA, like RNA, is a nucleic acid, a structure basically formed by the nucleotide.
DNA in the nucleus of a cell contains the genetic instructions for traits that are passed on to the next generation. They are found in segments of DNA known as genes and are copied and passed on during reproduction.
The hereditary material in the nucleus of a cell that is responsible for passing traits to the next generation is known as DNA (Deoxyribonucleic Acid).
DNA is a long molecule that contains our unique genetic code and holds the instructions for building the proteins that our bodies need to function. This information is located in specific segments of the DNA molecule called genes. Each gene provides a different set of instructions, for example, instructions for eye color, hair color, height, etc.
When reproduction occurs, these genes are copied and passed on from parents to their offspring, ensuring the continuity of traits from one generation to the next. Changes or mutations in these genes can lead to varied traits among individuals, which contributes to evolutionary diversity within species.

Scientific investigation is crucial in the development of the Theory of Natural Selection. This was illustrated by Charles Darwin and Alfred Russel Wallace in the 19th century, who used systematic observation, measurement, and experimentation to formulate the theory that diversity of life arose gradually through natural selection. A notable example is Darwin's research on finches in the Galapagos Islands.
The role of scientific investigation in the development of the Theory of Natural Selection is crucial. Scientific investigation involves the systematic observation, measurement, experiment, and the formation of theories or hypotheses, which are then tested.
In the 19th century, Charles Darwin and Alfred Russel Wallace independently devised the Theory of Natural Selection which proposed that the diversity of life arose through gradual changes in populations over time. They built this theory based on years of careful observation, note-taking, and hypothesis-testing - in essence, systematic scientific investigation.
For example, Darwin observed different variations of finches across the Galapagos Islands and made notes on their physical traits and habitats. Through rigorous analysis of this data, he eventually proposed that each species of finch adapted over generations to best suit its environment via the mechanism of natural selection.
So, scientific investigation played a fundamental role in the formulation and further development of this transformative biological theory.

Glen throws the ball and yells, “Pineapple!” Thor does not fetch the ball.
Here, the process of operant conditioning that Thor has demonstrated is- stimuli discrimination.
A stimuli or stimulus discrimination is a behavior which results in one consequence in a particular setting and another consequence in other settings.
Yes, the importance of an element in the body related to its percentage of body weight.
That element that is present in a large amount are more important for the structure and function of the body. The human body is approximately 99% consist of six elements which is Oxygen, hydrogen, nitrogen, carbon, calcium, and phosphorus.
The five elements are present in 0.85% on the basis of boy weight which is sulfur, potassium, sodium, chlorine, and magnesium so we can conclude that percentage of element in the body tells us about its importance.

The importance of an element in the body is not solely based on its percentage of body weight. Elements' importance is determined by their function and essentiality to biological processes. Oxygen, although abundant in the body, is necessary for cellular respiration and energy production.
The importance of an element in the body is not directly related to its percentage of body weight. While some elements may have a higher percentage in the body, their importance is determined by their function and essentiality to biological processes.
For example, oxygen is the most abundant element in the body and has a high percentage of body weight. This is because oxygen is essential for cellular respiration and energy production.
On the other hand, elements like iodine and iron may have a lower percentage in the body, but they are crucial for functions like thyroid hormone synthesis and oxygen transportation, respectively.

Answer:
CCD Technology, actifed tablets and semiconductors
Explanation:
Semiconductors now absolutely used in every electronic device made which earlier were developed in integrated circuits for making reliable electronic devices that were compact and wouldn't fall apart during lift off.
CCD technology was developed to take compact cameras into space which are now sold as digital cameras in every store.
Actifed tablets were developed as a non-drowsy way of combating illness in space which are now sold as an over the counter cold remedy.
