Why do we need friction in our world?

Answer:

I will not allow due to presence of organisms there.

Explanation:

No, I will not allow the construction of the infrastructures on  the large hectares of hills and forests because forests provides habitat to millions of organisms and also helps in preventing floods. I will suggest them to build infrastructure on the uncultivated land or choose a rocky solid land where vegetation is not possible. Rocky land is good for infrastructure because there is no vegetation cultivation is possible so the land is useless and good for infrastructure.

Answer:

Genetic diversity can and will allow the flies to adapt differently, and learn how to survive with the pollution in the air. There may also be different traits that help them survive the pollution.

Explanation:

If they were all the same they could be quickly killed off and may never have the chance to adapt the the changing environment around them.

Answer:

Genetic diversity can increase the chance of the fly's population to better adapted or resistant to pollution.

Explanation:

Genetic diversity refers to the variation among the genes contained in a particular species or organism.

Genetic diversity will help the fly population to survive an exposure to pollution from a factory by increasing their adaptation to the pollution. It is very likely that some of the fly population would contain allelic variation that will help them resist the effect of pollution in the forest. The surviving flies will produce off springs that will carry the set of resistant genes.

Mutualism is an ecological connection between two or more species when each species benefits in some way from the interaction. Mutualism is an illustration of a typical ecological relationship.

The most frequent definition of mutualism is that it refers to interactions between members of different species that are advantageous to both parties, which displays the positive characteristics of the results of those interactions. Nevertheless, a more exact definition of mutualism is an interaction between individuals of various species that has a positive impact on per capita reproduction and/or survival of the interacting populations. Whereas only one partner species can give mutualistic benefits in species-specific mutualisms, several different species can do so in generalized mutualisms.

Animal communication systems may have evolved in different ways, depending on the precise selective pressures operating on them. An honest signal is one conclusion that can be made, but it is not the only one.

John Maynard Smith and David Harper suggested the hypothetical chase-away selection model of communication development in 2003. In this hypothesis, the preferences of picky females cause a signal that initially evolved to communicate honest information (such as the quality of a male's territory or his capacity to provide resources) to become exaggerated over time.

Therefore, the given statement is False.

Answer:

At B part.

Explanation:

At B part the nightfall will happen first because the B part is in the shade and will not present in front of the sun. When the earth rotates its own axis, the shaded part which is B comes in front of sun which means day time is started while on the other hand, the A part is in the shade and will experience nightfall so we can say that the nightfall occurs at B part of the earth.

The relative humidity is approximately 22.9% based on the given wet bulb temperature of 10°C and dry bulb temperature of 14°C.

Wet bulb temperature: 10°C = 50°F

Dry bulb temperature: 14°C = 57.2°F

SVP at wet bulb temperature: 0.284 * \(e^(17.27 * 10 / (10 + 237.3))\)= 0.284 * \(e^(-7.09)\) = 0.284 * 0.000828 = 0.0002356 psi

SVP at dry bulb temperature: 0.284 *\(e^(17.27 * 14 / (14 + 237.3))\) = 0.284 * e^(-5.97) = 0.284 * 0.002562 = 0.0007296 psi

AVP = 0.0002356 - (0.00066 * (57.2 - 50) * 14.7) = 0.0002356 - (0.00066 * 7.2 * 14.7) = 0.0002356 - 0.0686 = 0.000167 psi

RH = (AVP / SVP at dry bulb temperature) * 100

RH = (0.000167 / 0.0007296) * 100 = 0.229 * 100 = 22.9%

The amount of snowfall a particular area receives depends on a variety of factors such as its geographical location, elevation, and proximity to large bodies of water.

Grand Rapids is located in the western part of Michigan, which is known to receive more snowfall than the eastern part, where Detroit is located. This is because of the lake-effect snow phenomenon, which occurs when cold air moves over the relatively warmer waters of Lake Michigan. The moisture from the lake evaporates and rises into the atmosphere, where it condenses and forms snow clouds.

These clouds then release snow as they move over the land, resulting in heavy snowfall in areas close to the lake. Grand Rapids is situated closer to Lake Michigan than Detroit, and therefore experiences more snowfall as compared to Detroit, which is farther away from the lake. Additionally, the elevation of Grand Rapids is higher than that of Detroit, which can also contribute to higher snowfall amounts.

If an atom has more electrons as compared to the proton then we can say that the atom has a negative charge.

Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge.

You can have a positive or negative electric charge (commonly carried by protons and electrons respectively).

We may say that an atom has a negative charge if there are more electrons in it than there are protons.

The positively charged atom is known as the cation while on the other hand the negatively charged atom is known as the anion.

Thus, If an atom contains more electrons than protons, we may say that it has a negative charge.

(a) Synonymous mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A synonymous mutation occurs when a gene changes its nucleotide sequence but the amino acid sequence remains unchanged. An example of this type of mutation using AAGTGC is AAGTGT. The translated sequence would still be Lysine (AAG) and Cysteine (TGT). This is because TGT is a codon for Cysteine, so the amino acid sequence remains unchanged.

(b) Non-synonymous missense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous missense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is also changed. An example of this type of mutation using AAGTGC is AAGTGA. The translated sequence would be Lysine (AAG) and Glutamic acid (TGA). This is because TGA is a codon for Glutamic acid, so the amino acid sequence is changed from Cysteine to Glutamic acid.

(c) Non-synonymous nonsense mutation: AAGTGC is the normal sequence coding for Lysine (AAG) and Cysteine (TGC). A non-synonymous nonsense mutation occurs when a gene changes its nucleotide sequence and the amino acid sequence is changed to a stop codon. An example of this type of mutation using AAGTGC is AAGTAA. The translated sequence would be Lysine (AAG) and Stop codon (TAA). This is because TAA is a codon for Stop codon, so the amino acid sequence is changed from Cysteine to Stop codon, which causes the protein to be truncated.

The two processes involved in a biogeochemical cycle that cause atoms of elements to be recombined into new products are known as the biological and chemical processes.

The biological processes involve living organisms, such as plants and animals, which absorb and utilize elements for various cellular processes. For example, plants absorb carbon dioxide and water to produce glucose through photosynthesis, which is a biological process.

This glucose can then be used for energy by the plant or consumed by an animal. When the animal consumes the plant, the carbon and other elements are transferred from the plant to the animal, and the cycle continues. The chemical processes, on the other hand, involve non-living components such as rocks, soil, and water. These processes include weathering, erosion, and sedimentation, which can break down rocks and minerals to release elements into the environment.

For example, weathering can break down calcium carbonate in rocks to release calcium ions into the soil, which can then be taken up by plants for growth. Chemical reactions can also occur in the atmosphere, such as the conversion of nitrogen gas into usable forms by lightning strikes and nitrogen-fixing bacteria.

Together, these biological and chemical processes work in tandem to move elements through biogeochemical cycles, creating new products and supporting life on Earth.

The 40 mm Hg is the pressure gradient across the capillary bed in an uplifted arm due to the hydrostatic pressure change.

Millimeters of mercury are typically used to express pressures within the cardiovascular system (mm Hg). The CHP is quite high around 35 mm Hg. when blood leaving an arteriole enters a capillary bed for the first time. This initial CHP gradually decreases as the blood passes through the capillary, and by the time it reaches the venous end, it is only around 18 mm Hg. The BCOP, in contrast, stays relatively constant along the length of the capillary at around 25 mm Hg and is significantly lower than the osmotic pressure in the interstitial fluid because the plasma proteins continue to be suspended in the blood.

Hence, pressure gradient between capillaries direct lymph flow.

The given statement "The three categories of neurons are called neurons, neurons, and interneurons" is B.  False because  The three categories of neurons are  called sensory neurons, motor neurons, and interneurons.

Sensory neurons are responsible for transmitting sensory information from the body's tissues and organs to the brain and spinal cord. Motor neurons, on the other hand, are responsible for transmitting signals from the brain and spinal cord to the muscles and glands in the body, allowing for movement and other bodily functions. Finally, interneurons are responsible for connecting sensory and motor neurons, allowing for communication and coordination between the two.

It is important to note that these three categories are not mutually exclusive, as some neurons can have characteristics of multiple categories. For example, some sensory neurons can also act as interneurons, transmitting signals between different sensory neurons or between sensory and motor neurons. Similarly, some motor neurons can also receive sensory input, allowing for fine control of movement.

In summary, the three categories of neurons are  called sensory neurons, motor neurons, and interneurons, and they play important roles in allowing for communication and coordination within the nervous system. Therefore the correct option is B

The difference in height between the two bottles is 30 millimeters.

To calculate the difference in height between the two bottles in millimeters, we need to convert the heights from centimeters to millimeters and then subtract one from the other.

First, we convert the height of the first bottle from centimeters to millimeters. Since there are 10 millimeters in a centimeter, we can multiply the height of 12 centimeters by 10 to get the height in millimeters:

12 centimeters * 10 millimeters/centimeter = 120 millimeters.

Next, we convert the height of the second bottle from centimeters to millimeters using the same conversion factor. We multiply the height of 15 centimeters by 10:

15 centimeters * 10 millimeters/centimeter = 150 millimeters.

Now that we have both heights in millimeters, we can calculate the difference. We subtract the height of the first bottle from the height of the second bottle:

150 millimeters - 120 millimeters = 30 millimeters.

Therefore, the difference in height between the two bottles is 30 millimeters.

Answer:

A:in isotonic solution both cells remain of same size.

B:in hypotonic solution , both cells will expand in size but due to the rigid plant cell wall it will not be able to expand to the degrees of an animal cell.

C:in hypertonic solutions , both cells will shrink in size

Explanation:

hypotonic solutions means that the osmolarity is less than that of the cellular cytoplasm(like less salt in water than that of cytoplasm), so water moves from low concentration(the solution with less salt) to high concentration(the solution with more salt). Therefore in case of hypotonic water moves from surrounding solution to inside of cell thus expanding the size.

Vice versa is true for hypertonic solution.

So just remember water moves from low concentration of solute(salt) to high concentration.
