Allele frequency refers to: The total number of alleles in an individual. The number of alleles in a dimorphic population. The proportion of an allele relative to the total number of alleles in a population. The number of alleles that can exist for a certain gene.
Answer:
The proportion of an allele relative to the total number of alleles in a population.
Explanation:
The genic or allelic frequency refers to the proportion of each allele in a given locus of a specific population. If the population is under the Hardy-Weinberg equilibrium, the sum of the allelic frequencies always equals 1.
The allelic frequency is significant while analyzing the gene transition in the population. Also, genotypic frequencies are directly related to allelic frequencies, mathematically defining them.

Which of the following is not a difference between photosynthesis and cellular respiration?
Answer: D
Explanation: They both play an important role in the carbon cycle. Photosynthesis removed CO2 from the atmosphere while cellular respiration causes the release of CO2 into the atmosphere.
The others are major differences
Photosynthesis has as its products Starch and O2 while those of cellular respiration are water , CO2 and energy.
The materials needed for photosynthesis are water and CO2 while those for cellular respiration are starch and O2
Photosynthesis occurs in chloroplast while respiration takes place in mitochondria .
Thus the only non- difference is D.
¿A qué se debió el incremento en la cantidad de oxígeno en la atmósfera hace miles demillones de años?
Debido a que el hidrógeno molecular expulsado por los volcanes se difundió en el espacio, la Tierra ganó una atmósfera rica en oxígeno. Otra posibilidad es que el oxígeno se acumule debido a una disminución de gases – como el hidrógeno – que reaccionan con y por lo tanto "absorben" el oxígeno.

Scientists are studying how the construction of a farm affects the blood diversity of insects in a forest before the Farm was constructed 186 insect species were present the scientist find out that after the farmers constructed the number of insect species decreased By 4% per month. Based on this trend which function could be used to calculate how many months, f(n) it Will take for the number of insect species to reach the value of N?
Answer:
The function [tex]f(n)=log_{0.96}(\frac{n}{186})[/tex]
Explanation:
Wherever we are studying logarithmic decrease or increase, we can construct our logarithmic function following the next recipe :
[tex]f(n)=log_{x}(\frac{n}{y})[/tex] (I)
Where [tex]''n''[/tex] is the value that we want to obtain (following a logarithmic decrease or increase).
Where [tex]''f(n)''[/tex] is the time needed to obtain that variation.
Where [tex]''x''[/tex] is the parameter related to the percentage decrease or increase
And where [tex]''y''[/tex] is known as the original population.
Now let's use the question to learn how to use the expression (I) :
In order to find the parameter [tex]''x''[/tex] we need to know how porcentual the population changes. We know that the number of insect species decrease by 4 % per month.
Therefore, for the initial month we will have the 100 % of the number of insect species. For the first month we will have a decrease of 4 % which can be written as the 96 % of the original population.
We write 100 % - 4 % = 96 % ⇔ [tex]1-0.04=0.96[/tex]
That's how we obtain the parameter [tex]x[/tex]. In this case we subtract 0.04 to the original population 1 because we have a decrease. Otherwise we would have added if we had had an increase. The number 0.96 represents that month by month we obtain the 96 % from the previous month. The value from the parameter is [tex]x=0.96[/tex]
Now the original population of insect species is [tex]186[/tex]. Therefore the value for [tex]y[/tex] is [tex]y=186[/tex]. Using the values obtained in the expression (i) we have :
[tex]f(n)=log_{0.96}(\frac{n}{186})[/tex]
For example,
We have [tex]186[/tex] number of insect species at the time origin. A decrease of 4 % can be calculated as
[tex](186)(0.96)=178.56[/tex] which is the value expected for the first month. Now if we use this value in the expression (I) :
[tex]n=178.56[/tex] ⇒ [tex]f(178.56)=log_{0.96}(\frac{178.56}{186})=log_{0.96}(0.96)=1[/tex] ⇒
[tex]f(178.56)=1[/tex]
This means that to obtain 178.56 number of insect species we need to wait one month to achieve this value. Which fits with the problem data.
Answer:
f(n)=log0.96(n/186)

Explanation:
A sensory system can be defined as components of the central nervous system (CNS) which comprises of the brain, neural tissues or pathways and sensory neurons responsible for sensory functions, perception and processing sensory informations such as sound, light, heat, etc.
Generally, the nervous system found in living organisms such as humans, comprises of two (2) major components or systems; a central nervous system (CNS) and a peripheral nervous system (PNS).
Basically, the central nervous system (CNS) interprete the neural signals that are generated from stimuli that are detected by the sensory system. The five (5) main sense organs in the sensory system are: skin, tongue, ears, nose and the eyes. Some of the terminologies and features associated with the sensory system includes the following;
I. Adaptation: loss of sensitivity due to repeated stimuli. Stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal).
II. Filiform papilla: helps manipulate food on tongue surface. These are the thread-like dots found on the tongue and they typically cover two-third (⅔) of the human tongue.
III. Gustation: sense of taste. It is the ability of a living organism to taste flavors in a food or other things.
IV. Bowman's gland: produces mucus. It's a nasal gland found in the olfactory mucosa and responsible for the production of mucus in living organisms.
V. Basal cell: stem cell of olfactory receptor.
VI. Vallate papilla: contains taste buds for bitter substances.
VII. Olfactory: sense of smell. This is the ability of a living organism to perceive or smell something.
VIII. Sustentacular cell: supportive cell of olfactory receptor.
IX. Cranial nerve I: cranial nerve for taste.
X. Cranial nerve VII: cranial nerve for smell.

Which of the following statements best describes the function of a
competitive inhibitor in an enzyme-catalyzed reaction?
A. The inhibitor damages the enzyme, preventing the substrate from
binding to the active site.
B. The inhibitor damages the substrate when the substrate attempts
to bind to the enzyme's active site.
C. The inhibitor binds to the enzyme's active site, because its shape
is similar to that of the substrate.
D. The inhibitor damages one or more products after the enzyme
releases them following the reaction.
SUBMIT
Answer:
C. The inhibitor binds to the enzyme's active site, because its shape is similar to that of the substrate.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Generally, enzymes function best at a specific pH and temperature level. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
An inhibitor is any substance that slows down or stops a biological process or chemical reaction.
Hence, the statement which best describes the function of a competitive inhibitor in an enzyme-catalyzed reaction is that the inhibitor binds to the enzyme's active site, because its shape is similar to that of the substrate and consequently, slowing down or stopping the process.
An enzyme may be described as an organic catalyst that usually lowers the activation strength of an organic response. The correct answer is C. The inhibitor binds to the enzyme's active site because its shape is similar to that of the substrate.
When the activation strength of the response is low, the charge of the response could be faster. Therefore, an enzyme speeds or catalyzes the charge of a response by decreasing its activation strength. Also, if the situations aren't most desirable for an enzyme, it limits the capacity of an enzyme to bind or be joined with its substrates.Generally, enzymes feature pleasant at a selected pH and temperature level. A boom in temperature will increase or hastens the charge of a response even as low-temperature limits or reduces the charge of the response. The most desirable temperature for enzymes withinside the human frame is around 37 stages celsius.What is an inhibitor?An inhibitor is any substance that slows down or stops an organic procedure or chemical response.
Hence, the announcement which high-quality describes the feature of an aggressive inhibitor in an enzyme-catalyzed response is that the inhibitor binds to the enzyme's lively site, due to the fact its form is just like that of the substrate and consequently, slowing down or preventing the process.

Explanation:
Which events are evidence that your brain responds to stimuli in your environment?
Answer:
Answer :- Step 1 Receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment or from inside your body.
Step 2 The central nervous system processes information received from the peripheral nervous system.
Step 3 The central nervous system sends out the processed information to the peripheral nervous system.
Step 4 The peripheral nervous system sends a message to the body part that needs to respond so you can react appropriately to the stimulus.
Explanation:-
There are two different parts of the nervous sytem-the peripheral nervous system (PNS) and the central nervous sytem (CNS).
The CNS consists of the brain and the spinal cord .
The PNS consists of all the nerves that lie outside the CNS.
The main function of the PNS is to gather information from the sensory receptors located in our body and convey this information to the central nervous system.
The CNS collects this information from the PNS and then interprets it. The interpreted information is then relayed back to the body parts via the PNS to perform the appropriate action
