The question is kind of confusing but from what I understand; missense mutations happen when an amino acid is changed to another amino acid. To find out more specifically, look at a codon chart trust me it helps so much lol (just search codon chart and go to images). missense mutations can also cause a premature stop codon so look for a changed amino acid and a stop codon when u look at the codon chart. maybe if u see the different pairs you can get a more specific answer. I hope this helps :)

In a certain breed of dog, the alleles B and b determine black and brown coats respectively. However, the allele Q of a gene on a separate chromosome is epistatic to the B and b color alleles resulting in a gray coat (q has no effect on color). If animals of genotype B/b ; Q/q are intercrossed, what phenotypic ratio is expected in the progeny
Answer:
12 gray , 3 black, 1 brown
Explanation:
If Q allele of a gene on a separate chromosomes is epistatic to the B (black) and b (brown) color alleles, in cross between two animals with genotypes BbQq produces 12 gray coat color, 3 black coat color and 1 brown coat color animals.
BbQq x BbQq
Gray coat Gray coat
BQ Bq bQ bq
BQ BBQQ(gray) BBQq(gray) BbQQ(gray) BbQq(gray)
Bq BBQq(gray) BBqq(Black) BbQq(gray) Bbqq(Black)
bQ BbQQ(gray) BbQq(gray) bbQQ(gray) bbQq(gray)
bq BbQq(Gray) Bbqq(Black) bbQq(gray) bbqq(brown)
So the phenotypic ratio is Gray : Black : Brown
= 12 : 3 : 1
How does the central bank Control branch
Answer:
Central banks control and manipulate the national money supply: issuing currency and setting interest rates on loans and bonds.
Explanation:
To ensure a nation's economy remains healthy, its central bank regulates the amount of money in circulation. Influencing interest rates, printing money, and setting bank reserve requirements are all tools central banks use to control the money supply.

Eutrophication occurs when excess nutrients are supplied to a region, leading to an algae bloom and ultimately ______
A. Coral bleaching
B. Ocean deoxygenation
C. Ocean acidification
D. Overfishing
Answer:
The correct answer is - B. Ocean deoxygenation.
Explanation:
Eutrophication is the process in which a water body gets excessively rich in nutrients that leads to the algal growth or plankton growth in this region and covers the complete surface or most of the water body.
Due to this algal and plankton growth, there is a significant decrease in the concentration of the dissolved oxygen in water bodies that result in the incapability of supporting the lives found in it. The primary and main reason for this deoxygenation is eutrophication. Ocean deoxygenation is the reduction of the oxygen concentration of the oceans.

Please read the article Why Cats Have Nine Lives by Jared Diamond. Our analysis did not attempt to
answer the question of "Why" cats survive they way they do from different heights. What are some of
the assumptions the author makes that he uses in an attempt to answer this new question?
The author assumes that the question can be answered by applying principles of anatomy, physics and evolutionary biology. First reason he suggests is that cats are small and they have a favourable mass-surface area ratio. Next, he suggests that cats have soft tissues that absorb the shock and they land on all four limbs, dividing the shock. This is because of their body shape and its centre of gravity. He says that felines have this kind of body structure (that canines lack) because years of falling from trees etc. has evolved their body in this way.
The following assumptions that stem from the Straightforward theory were used by the author to explain why cats have nine lives. They include;
The larger mass of bigger animals causes more impact stress on landing.The unique vestibular systems of the cats and the gyroscopic turns they make that have their four feet pointing downwards before landing.The cats reach terminal velocity faster and extend their limbs reflexly to absorb the shock from the fall.The dissipation of the impact force due to their flexed limbs.Lastly, their evolutionary history that has seen them falling from trees frequently over the years.In his article, Jared Diamond profers several reasons why he believes that cats tend to suffer fewer injuries and fatalities after falling from different heights.
He believes that their mass which is lower in comparison to humans makes it possible for them to not suffer much impact force on landing.
The gyroscopic turns they make before landing makes it easier for them to land on their four feet thus suffering fewer injuries to the arms.
Their evolutionary history is another factor. Over the years, they have adapted so well to falling from heights.

Viral binding to human cells is inhibited by the antiviral drug.
Well-designed antiviral drug inhibited Viral binding to human cells so that the virus can't get the place of attachment and unable to use the cell's machinery for its growth and multiplication. In this way, the humans can be prevented from having the viral infection. There are some other mechanisms also used by the antiviral drug to inhibit the growth of virus in the human body such as uncoating of virus and synthesis of new viral components.

The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period. Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals
Answer:
Due to dormancy.
Explanation:
Plants have an advantage in surviving mass extinction because Plant seeds can remain dormant for many years in the soil without damaging and comes out from the soil when the conditions of the external environment become suitable. Plants can remain in dormant condition for a large period of time while on the other hand, animals have no such type of advantage so that's why plants survive mass extinction.

In an experiment, a small dialysis bag is filled with a 20% salt solution. It is placed in a
beaker filled with a 40% salt solution. Assuming that water can pass through the
small pores of the dialysis bag, whereas the large salt molecules cannot, what will
happen to the size of the dialysis bag?
Answer:
The bag will get smaller
Explanation:
Osmosis can be defined as the process of diffusion or movement of water molecules across a semipermeable membrane from an area of higher concentration of water (i.e., lower concentration solution) to a lower concentration of water. For example, in cells, there are specialized pores called 'aquaporins' which are membrane proteins that form channels to transport water molecules by facilitated diffusion. In this case, the outside of the bag has a higher salt concentration than inside, thereby water molecules will move by facilitated diffusion through pores from inside to outside the bag.
Explain in detail what caused the population of peppered moths to change from mostly light-colored variations to mostly dark-colored variations in the 1800s. Explain how the peppered moth mutation is an example of natural selection. Explain what would happen to the populations of both variations of peppered moth once the pollution disappeared. Determine which variation of the peppered moth would be more successful in your neighborhood, and explain in detail your reasoning supporting your conclusion. Predict what may happen to the population of peppered moths if they were relocated to a lush, green rainforest ecosystem. How would this impact natural selection and their struggle to survive?
Answer:
Natural selection caused the population of peppered moths to change from mostly light-colored variations to mostly dark-colored variations in the 1800s. Pepper colored moths camouflaged among trees but after industrial revolution the couldn't because of soot, which camouflaged black moths; hence, they were preyed upon more.
