PROTEINSExplanation:
Many important molecules in the hman body are proteins like enzymes, antibodies, e.t.c.
Enzymes are a type of protein that speed up chemical reactions.
All enzymes are examples of organic molecules known as proteins.
Proteins are large biomolecules composed of one or more chains of amino acids that perform a wide range of functions in living organisms. Proteins are essential structural and functional components of cells, tissues, and organs.
Enzymes are biological catalysts that are produced by living cells. They are typically composed of one or more proteins, which are long chains of amino acids that are folded into complex three-dimensional shapes. Enzymes play a critical role in many biological processes, including digestion, metabolism, and DNA replication. \They work by lowering the activation energy required for a given chemical reaction to occur, which allows the reaction to proceed more quickly and efficiently.Therefore, enzymes are proteins, they are considered to be organic molecules.

Question 13 options:
Pepsin will break down glucose molecules into simpler substances.
Pepsin will react with glucose only if the necessary RNA molecules are present.
Pepsin will probably NOT react with the sugar glucose since it is an enzyme that breaks down proteins.
Pepsin will probably NOT react with glucose since the activity of enzymes is limited to the human body.

Scientific theories are explanations of natural phenomena that have been repeatedly examined and verified using the scientific process of observation, measurement, and analysis. Therefore, option (A) is correct.
What is scientific theory?A scientific theory is an explanation of an aspect of the natural world and the universe that has been repeatedly tested and corroborated in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of the results. In other words, a scientific theory is an explanation of something that has been proven to be true through the scientific method.
Einstein's Special Relativity, which describes the relationship between space and time for objects moving at a consistent speed in a straight line, is one of the most well-known scientific ideas. It also happens to be one of the most controversial. Additionally, the concept of time dilation is investigated by this theory.

An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.
Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.
For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.

TOR kinases are enzymatic proteins found in a diversity of species, from yeasts to mammals. They serve in a phosphorylation cascade that promotes progression through the cell cycle. What evidence would confirm that eukaryotes share a common ancestor with regards to cell signaling pathways?
Answers
Answer:
By phylogenetic analyses
Explanation:
The target of rapamycin (TOR) is a major regulator of growth only found in eukaryotic organisms. The TOR pathway is known to regulate critical cellular processes including, among others, cell growth. The TOR protein is a kinase capable of activating translation by phosphorylation of the ribosomal S6 kinase (S6K) and the eukaryotic translation initiation factor 4E binding protein (4E-BP). In this regard, phylogenetic studies have shown that this pathway involves duplication events of ancestral kinases, as well as sub-functionalization of the S6K kinase.
