Explanation:
According to Bronsted-Lowry, acids are the species that donate protons or [tex](H^{+})[/tex].
For example, HCl is a Bronsted-Lowry acid as it releases protons upon dissociation.
[tex]HCl \rightarrow H^{+} + Cl^{-}[/tex]
On the other hand, species that take up or accept a protons or [tex](H^{+})[/tex] are known as Bronsted-Lowry base.
For example, [tex]NH_{3} + H^{+} \rightarrow NH^{+}_{4}[/tex]
Therefore, [tex]NH_{3}[/tex] is a Bronsted-Lowry base as it accepts a proton.

What example involves a cell membrane receiving and sending messages?
An example that involves a cell membrane receiving and sending messages is when the cells of an organism tell each other when predators are near. The membrane is very helpful in communication in the body. This question was already asked two times in Brainly, so if you want to go into more depth, I recommend you look at the answers there. :)
I hope this helps! :)
Answer: The signals are transferred from the brain to the various parts of the body and from the body to the brain.
Explanation:
The transmission of the signals though neurons can be defined as an example of cell membrane receiving and sending messages.
Any stimulus from the outer environment is transferred to the brain via signal transduction method and then response is generate as a feedback of the stimulus.
Which of these pollutants is biodegradable?
food waste
mercury
methane
lead
Answer:
Food waste
Explanation:
Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.
The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
Food waste is the biodegradable pollutant among the options, as heavy metals like mercury and lead accumulate in the environment and organisms without breaking down naturally.
Out of the options provided (food waste, mercury, methane, lead), food waste is the pollutant that is biodegradable. Biodegradability refers to a substance's ability to break down in the environment due to natural processes. Heavy metals such as mercury and lead do not biodegrade and instead can bioaccumulate in living organisms, posing significant health risks and environmental concerns. Methane, while a naturally occurring gas, is not typically referred to as biodegradable, as it does not break down into simpler substances through biological agents but rather dissipates over time through photochemical reactions in the atmosphere.

What can create submarine canyons by cutting through bottom sediments and bedrocks of seafloors
its turbidity currents
Final answer:
Submarine canyons are formed on continental shelves by turbidity flows, which are underwater landslides of sediment-rich water that erode the seafloor. These currents originate from river systems and the process is further intensified during periods of low sea level, leading to the gradual deepening and expansion of canyons.
Explanation:
Submarine canyons are significant geological formations found on continental shelves, often affiliated with large river systems that extend into the sea. These canyons can be created by turbidity flows, which are underwater landslides consisting of slurries of sediment-rich water that move down the continental slope. Turbidity flows have a density higher than the surrounding seawater, enabling them to carve through the seafloor sediments and bedrock.
Compute A population of 100 flowering plants contains 60 plants that are homozygous for orange flowers (OO), 30 plants that are heterozygous for orange flowers (Oo), and 10 plants that are homozygous for white flowers (oo). Determine the frequency of the O allele and the frequency of the o allele in this population. Show your work.
The answer is; The frequency for allele O = 0.7746 while that of o = 0.2254
Well use the hardy Weinberg equation of a population at equilibrium; p2 + 2pq + q2 = 1
In our case, p2 will be 60/100 = 0.6; therefore p = square-root of 0.6 = 0.7746
Remember also that the frequencies of alleles of the same gene add up to one (1); i.e p + q = 1
Therefore q = 1 – 0.7746 = 0.2254
The frequency of the O allele is = 0.7745
The frequency of the o allele is = 0.2255
What do you mean by Purebred?
When identical genes or alleles are considered at a particular gene locus. It is called purebred.
According to Hardy-Weinberg genetic equilibrium,
[tex]P^2+2Pq+q^2=1[/tex]; P+q= 1
Given, [tex]P^2[/tex]= 60/100 = 0.6, P= √0.6 = 0.7745.
The frequency of the O allele is = 0.7745
If P+q=1, then,
0.7745+q=1, q= 1-0.7745 = 0.2255.
The frequency of the o allele is = 0.2255.
Therefore, the frequency of both alleles is determined.

What term describes a species whose removal would affect many other species, both directly and indirectly
What term describes a species whose removal would affect many other species, both directly and indirectly: keystone species
Answer:
The correct answer is- Key stone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

How do The thickness and darkness of glass affect the amount of light that is transmitted
The thickness and darkness of glass affect the amount of light transmitted due to changes in speed of light (refraction), absorption, and interference of light. Thicker and darker glasses reflect and absorb more light, reducing the light transmission. The interference between light reflected from the top and bottom surfaces of the glass also affects light transmission.
Explanation:The thickness and darkness of glass can influence the amount of light that is transmitted through it. This phenomenon is linked to the interactions of light waves and the refractive index of the material. The glass can be analyzed as a thin film - a structure possessing a thickness smaller than a few times the wavelength of light. As light strikes the surface of the glass, it is partially reflected and partially refracted, a process that depends on the thickness of the film and the indices of refraction of the various media.
When light travels through a physical medium, its speed is altered, which can cause the light to change direction. This is called refraction. If we take into consideration a thicker or darker glass which might potentially absorb more light, the transmitted light will be less. Essentially, the thicker the glass or the more opaque it is, the less light transmission occurs. This is due to increased reflection and absorption of the light waves.
The other important aspect to keep in mind is that there can be interference of light that has been reflected from both the top and bottom surfaces of the glass. This interference can either be constructive or destructive, which depends mainly on the thickness of the glass and can affect the amount and color of the light transmitted.

Which of the following correctly identifies the types of cell division describe in rows x and y
Answer:
B. Row x describes meiosis and row y describes mitosis
Explanation:
Mitosis is the process in which a cell divides to yield two daughter cells with same number of chromosomes as the parent cell. The process takes place in the somatic cells or the body cells. For example, a cell with 14 chromosomes divides to produce two cells with 14 chromosomes.Meiosis on the other hand is the process in which a cell divides into four daughter cells that have half the number of chromosomes as the parent cell. The process takes place in the germ line cells where gametes are produced. For example a cell undergoes meiotic division to produce four cells each with 7 chromosomes.List from most polar to least polar
Chlorophyll a
Chlorophyll b
Beta carotene
Xanthophyll
The answer from most polar to least polar is:
Xanthophyll
Chlorophyll b
Chlorophyll a
Beta carotene (not polar at all)
Final answer:
From most polar to least polar, the order is Chlorophyll b, Chlorophyll a, Xanthophyll, and Beta carotene, due to their structural differences and the presence of polar functional groups in Chlorophyll b and a, as well as the oxygen content in Xanthophyll.
Explanation:
The polarity of pigments depends on their structure and the presence of functional groups that can participate in hydrogen bonding and other polar interactions. Considering the structures of the pigments involved:
Chlorophyll a has a methyl group (-CH3) in the structure where chlorophyll b has an aldehyde (-CHO).
Chlorophyll b is more polar than chlorophyll a due to the presence of the aldehyde group which can form more hydrogen bonds than a methyl group.
Xanthophyll contains oxygen and is also more polar than carotenes, which do not contain oxygen.
Beta carotene (ß-carotene) is the least polar because it lacks the oxygen-containing groups that are present in xanthophyll and chlorophylls.
Thus, the order from most polar to least polar is:
Chlorophyll b
Chlorophyll a
Xanthophyll
Beta carotene
Look at the two fatty acids below.
What factor determines how much linoleic acid can twist and bend its shape?
i would say A.
the double bond in an unsaturated fatty acid produces a kink in the molecule. The bend in the carbon chain, however, is much more pronounced in the cis isomer compared to the trans isomer. For this reason, cis fatty acids (and triacylglycerols made from them) do not solidify like trans fatty acids. Due to the larger bend, the cis isomers cannot line up next to one another in as ordered a fashion as the trans isomers and can be more flexible.
The number of double bonds will determine how much linoleic acid can twist and bend its shape. Hence, option A is correct.

Because of the large heat of __________ of water, the evaporation from a liquid surface is a very effective cooling mechanism.
Vaporization
The human body makes use of evaporative cooling by __________ to give off energy even when surrounded by a temperature higher than body temperature.
Perspiration
~Hope this answers your question!~
Answer:
Because of the large heat of vaporization of water, the evaporation from a liquid surface is a very effective cooling mechanism. The human body makes use of evaporative cooling by perspiration to give off energy even when surrounded by a temperature higher than body temperature.
Explanation:
Vaporization is the name given to the physical transformation from liquid to gaseous. In this transformation there are only changes in the physical character of the matter, that is, after its occurrence, the matter remains with the same constitution (composition). The water goes through the vaporization process that changes from liquid water to water vapor through temperature. Due to the great heat of water vaporization, the evaporation of a liquid surface is a very effective cooling mechanism.
Perspiration, in turn, is a normal and healthy bodily function, which begins to occur a few months after birth. Humans perspire to cool their body temperature. In science, this process is called thermoregulation. When it occurs, the brain sends a signal to more than 3 million glands in the body, which immediately release sweat. Sweat is a liquid composed of water, salts and proteins. As we sweat, this liquid evaporates from the skin to reduce body temperature. The human body makes use of evaporative cooling by perspiration to release energy, even when surrounded by a temperature above body temperature.
