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.

Which one of the following would be inhibited by a well-designed antiviral drug? Cell wall synthesis Viral binding to human cells Virus assembly outside of the infected cell Translation of host cell RNAs
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.

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.

a) PpAa x PpAA
b) PpAa x PpAa
c) PpAa x ppAA
d) PPAA x ppaa
e) PPaa x ppAA
Answer:
a
Explanation: the genotype is the same
Cross between same pea plants for many generations having genotype PpAa x PpAa because after crossing over parents character having a large number of phenotype in offspring, hence a is the correct option.
What is a genotype?The term "genotype" ranges to an organism's genetic makeup, in other words, it describes an organism's whole gene. The term can also be used to refer to the alleles, or variant forms of a gene, that an organism carries in a more specific meaning.
When crossing of particular traits having genotype PpAa x PpAa because after crossing over parents' character having a large number of phenotypes in offspring.
The genotype of a person is their own DNA sequence. More specifically, the two alleles a person inherited for a particular gene are referred to using this term.
Therefore genotype parents PpAa x PpAa offspring have a large number of traits the same as parents and a low number of new traits.

Answer:
The correct answer is - B.often bind their ligands via multiple weak interactions.
Explanation:
Lectins are specific types of proteins that identify and bind to specific carbohydrates present on the cell surfaces. They have an essential role in interactions and communication between various cells for identification and recognition.

Amoeba sisters video recap Biomagnification
Biomagnification refers to the presence of higher concentration of chemical toxins as a result of the accumulation of toxins in organisms.
What is biomagnigication?Biomagnification is best explained as a condition in which the chemical concentration of a toxin is amplified in an organism compared to the environment in which the organism is found.
Biomagnification usually is observed as one goes higher in the trophic levels of organisms.
For example, chemical pollutant found in water may be present at tolerable levels. However, in organisms, living in the water, the concentration of the pollutant is higher as these organisms accumulate these toxins in their tissues.
Therefore, biomagnification refers to the accumulation of toxins in organisms higher than found in their environment.

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.

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.

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
