why Guainen (G) is always paired with cytosine (C) with triple bond and so Adenine with Thymine with double bonds?
Answers
Answer:
In DNA and RNA, guanine forms three hydrogen bonds with cytosine. Three bonds are formed between these bases as a result of the fact that guanine possesses two nitrogen and one oxygen atoms that can form hydrogen bonds. Given the spatial restrictions of the double helix, which call for there to be one purine and one pyrimidine in each base pair, A always pairs with T and G always pairs with C as these are the only combinations that for hydrogen bonding to take place.

What is the blood group of a person who has neither antigen A nor B but is positive for antigen d
Answers
Antigen D refers to the Rh factor, which is another important component of blood typing. If an individual has the Rh antigen D, they are considered Rh positive (+), whereas the absence of the antigen D indicates Rh negative (-). Therefore, a person who lacks antigens A and B but has antigen D is classified as O positive (O+).
Answer:The blood group of a person who does not have antigen A or B but is positive for antigen D is classified as blood group O positive (O+).
Explanation: In the ABO blood typing system, there are four main blood types: A, B, AB, and O. These blood types are determined by the presence or absence of specific antigens on the surface of red blood cells. Antigens A and B are responsible for blood types A and B, respectively.
If a person lacks both antigen A and antigen B, they are considered to have blood type O. The positive (+) or negative (-) designation refers to the presence or absence of the Rh antigen, also known as the D antigen. A person who tests positive for the D antigen is Rh-positive.
Therefore, a person who does not have antigen A or B but is positive for the D antigen is classified as blood group O positive (O+).
How does adenosine triphosphate (ATP) become adenosine diphosphate (ADP)?
ATP stores energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is broken.
ATP stores energy as a phosphate bond is broken.
Answers
The correct answer is ATP releases energy as a phosphate bond is broken.
ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) when a phosphate group is removed from ATP, resulting in the release of energy. This process is known as hydrolysis, where water molecules are used to break the bond between the terminal phosphate group and the rest of the molecule.
During cellular metabolism, ATP serves as the primary energy currency of the cell. When energy is required for various cellular processes, the phosphate bond in ATP is broken by an enzyme called ATPase. This enzymatic hydrolysis reaction cleaves off one of the phosphate groups, resulting in the formation of ADP and an inorganic phosphate molecule (Pi). The released phosphate group is then available to be used in other cellular reactions.
The conversion of ATP to ADP is an essential part of energy metabolism in cells. The energy released during this process is utilized to drive various cellular activities, such as muscle contraction, active transport of molecules across cell membranes, and synthesis of macromolecules. Once ATP is converted to ADP, it can be further hydrolyzed to AMP (adenosine monophosphate) if more energy is needed. Ultimately, the energy stored in ATP is released when the phosphate bond is broken, allowing cells to perform their vital functions.

In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 504 mL. The reserve and residual volumes of air that remain in the lungs occupy about 2030 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.
Answers
Answer:
\(V(t)=252sin(\frac{\pi}{2}t )+2282\)
Explanation:
The volume of air increases and decreases, hence the volume of air can be represented as a sine function.
A sine function is of the form:
y = Asin(B(x - C)) + D
Where A is the amplitude, B is the frequency, C is the horizontal shift and D is the vertical shift.
Therefore, the total volume of air V(t) in the lungs as a function of time is given by:
V(t) = Asin(B(t - C)) + D
Since the volume of air in and out of the longs is 504 ml, hence the amplitude (A) = 504/2 = 252
There is residual air of 2030 ml minimum in the lungs and a maximum of 2534 ml (2030 ml + 504 ml), hence the vertical shift (D) = (2534 + 2030) / 2 = 2282 ml
The frequency B = 2π / 4 s = π/2
Therefore:
\(V(t)=252sin(\frac{\pi}{2}t )+2282\)

What type of human activities might threaten the spiny dogfish population?
Answers
The activities that threaten the spiny dogfish population are Overfishing, Climate Change, Illegal trade, Bycatch etc.
Overfishing occurs when the spiny dog fish are caught at the rate higher than their reproductive capacity. This can lead to depletion in the population of spiny dogfish. One more reason is Bycatch, in which they often get caught unintentionally and when sent back into the water, they may suffer injuries or die.
Climate Change also plays a major role in the population depletion of the spiny dogfish. Rising ocean temperatures and ocean acidification can affect the psychology, behaviour, prey availability, and can also disrupt their reproductive pattern.
Illegal Trade which involves unreported fishing practice, such as overfishing or catching undersized dogfish can result in the reduction of their population. These activities are carried out illegally by breaking laws, violating fishing quotas or without permits.

there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?

Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.
