Answer:
False
Explanation:
Bacterial flagella have a biological motor that spins within the cell wall and is NOT powered by ATP.
Instead the Bacterial flagella is known as the biological motor that spins the flagella for the motion of the bacteria and is as a result of the electron imbalance in the membranes which helps in the generation of a gradient. The cells makes use of the energy present in the gradient through the help of proton motive force which helps to propel it.
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.

Using radio telescopes, astronomers have found evidence
that no new matter is forming in the universe, which is
what the big bang theory predicted.
This work is part of which process used in developing scientific theories?
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C. Using new technology to replace outdated theories with new ideas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.

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.

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.

Give one example of how the testing of Platismatia glauca could benefit future ecological research of this forest.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.

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-
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?
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.

Answer:
No it is not a scientific theory.
Explanation:
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.
