Based on Figure 1, which of the following statements best describes the epinephrine signaling pathway?
Group of answer choices
It involves the opening and closing of ion channels.
In involves enzymes activating other enzymes.
It involves changes in the expression of target genes.
It involves protons moving down a concentration gradient.
Answer:
It involves enzymes activating other enzymes.
Explanation:
Epinephrine activates glycolysis (i.e., glycogen breakdown) in skeletal muscle and at a lower level in the liver, which is more responsive to glucagon. When epinephrine binds to a G protein-coupled receptor, the receptor changes its conformation and then triggers a molecular cascade that involves the production of cyclic adenosine monophosphate (cAMP), a well known second messenger molecule in signal transduction pathways. Moreover, the beta-2 adrenergic receptor (ADRB2) is a G-protein-coupled receptor known to activate adenylate cyclase enzyme that leads to appropriate increases in cAMP and activation of protein kinase A (PKA).
Based on Figure 1, the statement that best describes the epinephrine signaling pathway is:
B. It involves enzymes activating other enzymes.
Epinephrine signaling pathway occurs when the neurotransmitters in the body helps the hormones to communicate with the epinephrine.
When this happens, there is a reaction within the receptor, causing it to become active.
As a result of this, there is a binding with the G-protein receptor which releases the cyclic adenosine monophosphate (cAMP).
This in turn, activates the other enzymes.
Therefore, the correct answer is option B

A. Multicellular body systems
B. Codons based on a triplet code
C. DNA as the genetic material
D. Sub-cellular organelles
Answer:
B-Condon's based on a triplet code
Expl
The characteristic shared by all modern living systems among the options provided is DNA as the genetic material. Therefore option C is correct.
DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms. It is a long, double-stranded helix structure composed of nucleotides.
Thus, DNA as the genetic material is a fundamental characteristic shared by all known modern living systems.
It encodes the instructions necessary for the development and functioning of an organism, allowing for the transmission of genetic information from one generation to the next.

PLEASE HELP!!! A scientist concludes that genetic inheritance of a mutated (changed) gene, such as a gene change that creates different-colored organisms in a population, is more beneficial to an organism over time and contributes to biological fitness. Discuss why a scientist would make that claim.
i posted a few min. ago and someone stole 30 points by answering and saying they couldnt help. please answer the question if you can and dont steal my points....
Answer:
When the organism inherits a mutated gene creating new colored organisms into the population, this can increase diversity. As more organisms inherit the same mutation, the population will become more variated, which can increase the organisms abilities to survive and adapt in a changing environment, and also improve the biological fitness of individuals; resulting in allowing more organisms to reproduce successfully.

What does the "oxidative" in oxidative phosphorylation mean?
Oxygen is added to ADP to make ATP
Oxygen is necessary for the process which adds phosphorus to ADP
Oxygen phosphorylates ADP into ATP
Phosphorylating ADP into ATP releases oxygen as a bi-product
Answer:
B
Explanation:
Oxygen is the final acceptor of electrons in the process of oxidative phosphorylation. Without oxygen, the process becomes jammed with electrons.

Answer: If the question is "would the carbon levels decrease?" then they would not, they would increase.
Explanation: More airplanes and cars would burn fossil fuels, and release more carbon dioxide, increasing carbon levels, not decreasing them.
What BEST describes the roles of photosystem I and photosystem Il in the process of photosynthesis?
Answer:
Photo system 1 = Light
This is the presence of sunlight, whereby Chlorophyll is used to trap sunlight energy to split water molecules into hydrogen ions and hydroxyl ions also NADP is reduced by the addition of hydrogen to form NADH
Photo system II: Dark stage
It happens when there is abscence of light where by CO2 ingested by plants react with hydrogen atoms from the light stage to form the Emperial Formula of simple sugar. Also Hydroxyl ions (OH -) is furtherly broken-down to oxygen & molecules.

A student claims that electronegativity is not related to the
concept of polarity. Use water as an example to provide
reasoning to refute the student's claim.
PLEASE HELP!
Answer:
Please find the explanation below
Explanation:
Polarity of a molecule is the function of the difference between the electric charges of two atoms that make up the molecule. This polar nature is greatly influenced by the ELECTRONEGATIVITY, which is the ability to attract electrons, of the atoms involved. For example, using water molecule, H2O, as a case study.
Water is known to be a highly polar molecule due to the electronegativity values of the atoms that make up its molecule. Oxygen atom is a more electronegative atom than hydrogen, hence, it pulls more electrons towards itself, leaving the hydrogen atom more electropositive. This forms the difference in the electrostatic force between oxygen and hydrogen, making water POLAR.
HENCE, the student is wrong to have said electronegativity is not related to the concept of polarity.
