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.

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.

. Describea typical stress-strain curve and the relationship between the segments of the curve and stress and strain.
Answer:
the relationship between stress and strain that a particular material displays . it's unique for each material . it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress in a typical stress-strain curve , the breaking strength is less than the ultimate strength
Explanation:
The typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.
What is the significance of the stress-strain curve?A typical stress-strain curve has several segments, including the elastic region, which represents the stiffness of the material, and the plastic region, which represents the point at which the material begins to permanently deform. Necking: a reduction in cross-section; ultimate strength, then a material's ability to deform until it reaches its ultimate strength, and so on.
Hence, the typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.

Which of the following statements best describes the role of adenylyl cyclase in the epinephrine signaling pathway?
Group of answer choices
It converts a polymer to its monomer subunits.
It moves substances across the plasma membrane.
It accelerates the production of a second messenger.
It transfers phosphate groups from to protein substrates.
Answer:
It accelerates the production of a second messenger.
Explanation:
Adenylyl cyclase is an enzyme capable of converting ATP molecules into cyclic adenosine monophosphate AMP (cAMP). The cAMP molecule is considered to be a second messenger that transfers the hormonal signal (i.e., epinephrine) inside the cell. Subsequently, cAMP activates molecular signaling events by binding and thus activating cAMP-dependent protein kinase A (PKA). Finally, this last protein (PKA) phosphorylates different proteins that control many diverse cellular processes.
Dogs have 39 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each dog cell?
Answer:
39 daughter chromosomes
Explanation:
This question is describing the MITOTIC process, which involves the synthesis of two daughter cells from one parent cell. In mitosis, sister chromatids, which forms a chromosome, separates at their centromere to become individual chromosomes in their respective daughter cells.
N.B: Mitosis produces two daughter cells which are identical in chromosome number.
In this case, a dog is said to have 39 chromosomes in its diploid cell. Since two chromatids make up one chromosome, 78 chromatids will be found in the dog cell. The 78 sister chromatids that form 39 chromosomes will each separate at their centromere to form 39 daughter chromosomes in each daughter dog cell.

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
