There are fewer antivirals currently available in most pharmacies than there are antibacterials because
a. bacterial cells are less complex that viruses
b. selective toxicity is much easier to achieve for bacteria
c. most antivirals available are for uncommon, life threatening infections
d. antivirals are much more expensive to produce than antibiotics
Answers
Selective toxicity is much easier to achieve for bacteria, making the development of effective antibacterials more feasible.
The correct answer is (b) selective toxicity is much easier to achieve for bacteria. Selective toxicity refers to the ability of a drug to target and kill the pathogenic organism while causing minimal harm to the host. Bacterial cells are structurally and functionally distinct from human cells, making it easier to develop drugs that specifically target bacterial components without affecting human cells. This enables the development of antibacterials with high efficacy and relatively low toxicity.
In contrast, viruses are intracellular parasites that rely on host cells for replication. Targeting viral components while sparing host cells presents a greater challenge due to the similarities between viral and human cellular processes. Achieving selective toxicity for viruses is more complex, making the development of effective antiviral drugs more challenging.
Additionally, option (a) is incorrect because viral cells are not less complex than bacterial cells. Viruses can exhibit intricate structures and complex replication mechanisms. Option (c) is incorrect because while some antivirals may be specifically developed for uncommon, life-threatening infections, there are also antivirals available for common viral infections such as influenza and herpes. Option (d) is incorrect as well because the cost of drug production does not solely determine the availability of antivirals in pharmacies.

How much water would you need to add 225. 0 ml of 1. 500 m sugar solution to make a 1. 000 m solution
Answers
You would need to add 337.5 mL of water to the initial 225.0 mL of the 1.500 M sugar solution to obtain a final solution with a concentration of 1.000 M.
To calculate the amount of water needed to dilute the sugar solution, we can use the formula for dilution:
C1V1 = C2V2,
where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume, respectively.
In this case, we have C1 = 1.500 M (initial concentration), V1 = 225.0 mL (initial volume), and C2 = 1.000 M (final concentration).
To find V2 (volume of the final solution, which includes water), we rearrange the formula:
V2 = (C1V1) / C2.
Substituting the values, we get:
V2 = (1.500 M * 225.0 mL) / 1.000 M = 337.5 mL.
Therefore, you would need to add 337.5 mL of water to the initial 225.0 mL of the 1.500 M sugar solution to obtain a final solution with a concentration of 1.000 M.

Describe how the reactants of photosynthesis are the products of cellular
respiration and that the products of photosynthesis are the reactants of cellular
respiration.
Answers
Answer:
Photosynthesis produces: glucose and \(O_{2}\)
...from \(CO_{2}\), energy (light) and \(H_{2} O\)
Respiration produces: energy (ATP),\(CO_{2}, H_{2} O\)
....from glucose and \(O_{2}\)
Explanation:
These end products, namely \(O_{2}\) and glucose are then used in respiration...
Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.
They combine light energy from the sun, water, and carbon dioxide.
6\(CO_{2}\) + 6\(H_{2} O\) + (energy) →\(C_{6} H_{12} O_{6}\) + 6\(O_{2}\)
In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).
\(C_{6} H_{12} O_{6} + 6 O_{2} _{\to \\) \(6CO_{2} + H_{2} O + energy (ATP)\)The waste products, \(CO_{2}\) and \(H_{2} O\), result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants \(O_{2}\) and \(C_{6} H_{12} O_{6}\) in respiration.

Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

Answers
The movement of molecules across a cell membrane known as passive transport occurs without the use of cellular energy.
Special compounds can pass through plasma membranes to enter and leave the cell, keeping out dangerous substances and allowing in only necessary substances. Selectively permeable, plasma membranes let some compounds pass through while preventing others. If they abandon this selectivity, the cell won't be able to strengthen itself and would perish. The majority of passive membrane transfer methods are direct. Passive transport is a phenomena that happens naturally and does not require the cell to use energy to move. Instead of using cellular energy like active transport, which drives the movement of molecules across cell membranes, passive transport relies on the second law of thermodynamics.

The picture shows a hot air balloon in flight.
Decreasing the heat of the burner causes the
balloon to sink and increasing the heat causes
the balloon to rise. How does heat transfer affect
the motion of the air molecules inside of the
balloon?
Answers
Answer:
While conduction can be a painfully slow method of energy transfer, convection is more like a speedy locomotive. Convection is the transfer of heat energy via the vertical movement of the air. Remember those very thin layers of air in contact with paved surfaces on hot summer days? They can approach 140 degrees Fahrenheit thanks to conduction, but convection limits the thickening of those blazing hot layers of air. Just like a hot-air balloon lifting off the ground, blobs or "parcels" of hot air rise from the ground, carrying hot air skyward. This transfer of heat energy away from the ground by the vertical movement of air is called "free convection" or "natural convection." To understand the nuts and bolts of free convection, let's with the concept of buoyancy. Suppose that, while taking a swim, you submerge your favorite beach ball and then let it go. In a heartbeat, the beach ball will bob to the surface of the water. In scientific terms, the beach ball is positively buoyant. Now submerge a rock and then release it. It falls to the bottom of the pool because the rock lacks sufficient positive buoyancy to keep it afloat. Formally, we say that the rock has negative buoyancy.What makes the difference in the buoyancy between a rock and a beach ball? The answer is density. Formally, the density of an object is its mass (akin to weight) divided by its volume. The beach ball has a relatively large volume and small mass, making its density rather small and far less than the density of water. A rock, on the other hand, has a greater density than water, so it sinks. We can generalize these observations in this way: an object immersed in a fluid (water, air, etc.) is positively buoyant if the density of the object is less than the density of the fluid. Moreover, the magnitude of the buoyancy force depends on the difference in densities between the submersed object and the fluid - the greater the difference, the greater the buoyancy force.Okay, let's take our discussion out of the water and into the air. For the time being, let's start with a "parcel" of air ("parcel" is just a fancy name for a generic blob of air that we assume does not interact with surrounding air). Several factors can cause the density of the air to change, but we're going to focus on the effects of temperature on air density.

What is a pedigree?
A Pedigree is the representation of a family's history. This graph is used to track a trait through different generations, and analyze the inheritance pattern of a particular gene and its expression.
It is a tool used to understand how genes are transmitted from the parental generation to the descendants, and what are the probabilities of inheriting them.
Pedigree interpretation.
Family members→ Individuals are represented with geometrical figures.
→ Males are squares
→ Females are circles
Trait/Phenotype→ Healthy/normal/not affected individuals are represented with empty figures
→ Affected/mutated individuals are represented with solid black figures
Generations→ Each file is represented with a roman number, indicating the Generation.
In our pedigree, albinism is represented by solid figures.
Because nothing is said about Jack's genotype or phenotype, there are two possible options for this pedigree.
Option 1: Jack is heterozygous (Aa).
Veronica will be a black circle because she expresses albinism (aa). The rest of the family will be empty figures because they are carriers (Aa) or homozygous dominant (AA).In this case, Jack and Maya can transmit either a dominant or a recessive allele to their children.
Option 2: Jack is homozygous recessive (aa)
Veronica and jack will be a black figures because they express albinism (aa). The rest of the family will be empty figures because they are carriers (Aa).In this case, Jack can only transmit the recessive allele, while Maya can transmit either the dominant or the recessive allele.
In both cases, Veronica received the recessive allele from both her parents.
