The human stomach secretes an enzyme known as pepsin. This enzyme breaks down proteins into smaller chemical molecules called peptides. If pepsin was mixed in a laboratory with sugar molecules like glucose, what is the MOST LIKELY result?
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.
Answer:
3rd
Explanation:
pepsin cannot possibly catalyze a reaction for a molecule it has not been shaped to do for.

What is the role of transfer dna
Answer:
The transfer DNA (abbreviated T-DNA) is the transferred DNA of the tumor-inducing (Ti) plasmid of some species of bacteria such as Agrobacterium tumefaciens and Agrobacterium rhizogenes(actually an Ri plasmid). The T-DNA is transferred from bacterium into the host plant's nuclear DNA genome.

Explanation:
is auxin one of the most important group of plant hormones
Answer:
yes they are
Explanation:
because auxin are the most important hormones involved in adventitious root formation.
Answer:
Yes!
Explanation:
Auxin is one of the MOST important group of plant hormones! They promote the growth that is needed for plants. They produce the stems and the buds, and the tips of the roots for the plants. Without it, things would go bad, and a lot of things would go awry.

All enzymes are examples of organic molecules known as?
Answer:
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.

How can you explain how genetic similarities are due to common ancestry? Where do we get our DNA from?
Answer:
Actually our genetic code is unrepeatable, the union of the female x chromosomes of our mother and chromosomes and of our father, generate a diploid cell with a UNIQUE cellular genetic code.
What shows our descent from the same ancestor is mitochondrial DNA, this DNA is the same and is repeated throughout the human race.
Explanation:
Mitochondrial DNA is circular and is found in our organelle called mitochondria, responsible for cellular respiration and formation of the energy currency ATP-

The human genome is a diploid genome. However, when germ-line cells produce gametes, these specialized cells are haploid. What is the total number of chromosomes found in each of the gametes (egg or sperm) in your body
Answer:
23 chromosomes
Explanation:
The total number of chromosomes found in each of the gametes in the body of humans is 23.
The human genome is diploid (2n) with 46 chromosomes. The sex cells divide by meiosis - a reductional division that results in the halving of the chromosome number - during the formation of gametes. Hence, the gametes are haploid (n) with half the number of chromosomes (23) of the vegetative cells of the body.
Therefore, the eggs in females and the sperms in males each contain haploid (n=23) number of chromosomes.

A. Using new technology to provide additional supporting data
B. Using imagination to spark new ideas
C. Using new technology to replace outdated theories with new ideas
O D. Using new data to modify an existing scientific theory
Answer:
A
Explanation:
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.
