Which is the genotype of the sweet pea?
A.heterozygous dominant
B.heterozygous recessive
C.homozygous dominant
D.homozygous recessive
The answer is C (homozygous dominant)
Explanation:
According to the question, a flower colour gene in a pea plant possesses two different alleles, P and p. Lettercase is used to illustrate that allele P (upper case) is dominant over allele p (lowercase) i.e P will be expressed over p in the flower colour gene.
According to the question, the pea plant exhibits a purple flower colour and is labelled as PP. This genotype is said to be homozygous because the same alleles (P) make up the plant's genotype. Since the allele P coding for purple coloration is dominant, the purple sweet pea is said to be HOMOZYGOUS dominant i.e. possess the same dominant alleles for that gene.

Is it important before a blood transfusion to know blood types? Why? What are the benefits or consequences?
Answers
Answer:
It is extremely important to know all types of blood because if you donate the wrong type of blood to another person, he/she will get sick.
Explanation:
Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be extremely life-threatening.
Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F_a progeny?
A. 1 g
B. 4 g
C. 8 g
D. 10 g
Answers
Answer: choice D. 10g
Explanation:
The cross is AABB x aabb so the F1 progeny would have AaBb genotype.
The question states that dominant alleles(uppercase letters) contribute 4g and recessive ones contribute 1g to the weight of the plant.
so for AaBb we would have 4+1+4+1=10g.

In perspective, with Earth being 4,500,000,000 years old and humans being around 1,400,000 years; how long out of a 24 day time period have we as humans been here.
Answers
Answer:
Day time period have we as humans been here: 26 seconds
Explanation:
4,500,000,000 years = 1 day
1,400,000 years = X
X = 0.0003111
1 day = 86,400 seconds
0.0003111 = X
X = 26 seconds
In term of the Earth in 24-hour clock, Homo sapiens appeared on our planet only in the last 26 seconds, it means that in geologic time, humans have existed for only a brief time period and thereby it is a relatively new species.

13. Ranchers lobbied the government to eradicate wolves from Yellowstone National Park. Five years later the deer population had increased fivefold. The following winter 70% of the deer starved to death. Explain why this was bound to happen.
Answers
Answer: The overgrowth in deer population led to a food shortage.
Explanation:
Since the eradication of the wolves, the deer had no predator to keep their total population in check. Due to the vast amount of deer the food in the area was being eaten at a faster rate. Most of the deer died do to their environment not being capable of feeding that many deer.

You are monitoring the metabolism of two different cultures of the same species of yeast, which you have labeled Culture A and Culture B. One of your observations is that Culture A is using up about 10 times the amount of glucose per unit of time as Culture B. Which one of the following conclusions could you reasonably draw regarding these cultures?
A. Culture A would be accumulating lactic acid.
B. Culture A is being grown aerobically; Culture B is being grown anaerobically.
C. Only Culture A is recycling its NADH back to NAD+.
D. Culture A and Culture B are synthesizing the same amount of ATP per unit of glucose in glycolysis.
E. None of the above conclusions could be drawn from the information given.
Answers
Answer: D
Explanation: The experiment was set up using the very same species of yeast labeled differently. What this means is that they are of the same type or kind and thus would exhibit similar features from feeding to the metabolism of the food they take and subsequent production of by-products of the fermentation process. In this regard, therefore, the reasonable conclusion that can be drawn regarding these cultures is that both cultures A and B are synthesizing the same amount of ATP per unit of glucose in glycolysis (the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source).
g One can measure ATP production from isolated mitochondria in vitro (in a test tube). Changing the pH of the solution that the mitochondria are in results in a similar change the pH of the intemembrane space. If the pH of the solution that the isolated mitochondria are in is raised and everything else remains constant, what is the effect on ATP synthesis
Answers
Answer:
This will lead to an decreases in the ATPs synthesis. This is because low pH , high acidity favours ATP synthesis, because it increases the proton concentration for electrochemical gradients needed for energy that ATPase enzymes makes used of synthesis of ATPs.
Therefore a rise in the pH(low acidity) lowers protons levels, and therefore reduced electrochemical gradients , with a drop in energy for ATPs synthesis.
Explanation:
A channel protein specific for calcium ions was found to have a pore lined with six glutamate residues that participate in coordinating the calcium ion. What would happen to the selectivity of the pore if the Glu residues were mutated to Asp residues
Answers
Answer:
If the mutation takes place, then the shorter side chains of asp compare to Glu will affect the permeability of the transport protein to calcium ions. Specifically, the mutation will increase the sizes of the pore,which in turn decreases the selectivity for calcium ion. Hence this affect excitability of the cell.

In experiment #2 you are asked to use the scientific method to develop and execute a method of separating a mixture of sand, salt and iron pellets. Imagine you are in a lab and notice that a plate of bacteria grow faster in the presence of sunlight. After that single observation, you come to the conclusion that sunlight causes bacteria to grow fast. What would be the next step in the scientific method for this experiment?
Answers
Answer:
1. separation can be done with help of magnetic bar and filtration.
2. the next step will be testing the hypothesis.
Explanation:
1. Separation of iron pellets from sand, and salt first
Use a magnet
Due to magnetic force iron pallets will attach with it and separation will occur from sand and salt.
After separation of iron pallets, add water to mixture of sand and salt and heat until salt get dissolved then filter the salt water.
This will help in separating all three components of mixture to separate.
2. Bacteria growth
Hypothesis must be tested-
In this case a hypothesis and conclusion is represented. Conclusion is provided that in presence of sunlight growth of bacteria is faster. So the hypothesis must be verified by scientific experiment to be a valid theory by measuring or monitoring growth in presence of sunlight.

Which statement about enzymes is true?
An enzyme functions to increase the activation energy in a reacton.
Enzymes are proteins that function as catalysts in nonliving things.
Each enzyme can catalyze many different biochemical reactions.
Enzymes and substrates fit together like a lock and key.
Answers
Answer:
Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).
Explanation:
An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.
Why would a drop in blood pH have an undesirable effect on the proximal histidine's function?a. A drop in pH would make deprotonation more likely, and a deprotonated proximal histidine would be able to hydrogen bond to O2 to stabilize its binding to the heme.b. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to donate its electron density to the iron atom.c. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to hydrogen bond to O2 to stabilize its binding to the heme due to its positive charge.
Answers
Answer:
c. A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to hydrogen bond to O2 to stabilize its binding to the heme due to its positive charge.
Explanation:
Protonation refers to the addition of proton or H+ to the atom or molecule. If the pH of blood drop means acidic so it causes adverse effect on the function of proximal histidine because the proximal histidine gain proton and become cation. Due to this proton, proximal histidine is unable to make hydrogen bond between heme and oxygen and the blood is unable to transport more oxygen with hemoglobin from the lungs.
Why do sex-linked traits follow different patterns of inheratance than other traits
Answers
Answer:
Males and females have different sex chromosomes.
Explanation:
Sex Linked trait is controlled by the chromosomes while other traits are controlled by autosomes. The autosomal cells and traits have a constant characteristics in a human being. The chromosomal cells however vary. The male chromosome XY is different from the female chromosome XX.
This is the reason why sex-linked traits follow different patterns of inheratance than other traits as a result of the Males and females having different sex chromosomes is valid.
The stimulus interval has a profound effect on the contraction force of the muscle. In your own words explain what happened when the muscle was stimulated in rapid succession. At which interval did the volunteer's muscle twitches begin to merge together (summate)
Answers
Answer:
The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.
The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.
Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.
Explanation:
If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.
If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.
if the ratio of the ages of kisii and esinam is 3:5 and that of Esinam and Larry is 3:5 and the sum of the ages of all three is 147 years what is the age difference between the oldest and the youngest
Answers
Answer:
The age difference between the oldest and the youngest is 48.
Explanation:
Given the following data;
The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.
The ratio of the ages of Esinam (E) and Larry (L) is 3:5.
The sum of the ages of all three is 147.
Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);
LCM of 3,5 = 15.
Hence, the ratio of the three ages is now;
K:E:L = 9:15:25
Let their ages be denoted by x;
[tex]K:E:L = 9x:15x:25x[/tex]
The sum of all three ages is;
9x + 15x + 25x = 147
49x = 147
x = 147/49
x = 3.
To find the age difference between the oldest and the youngest;
The oldest is Esinam = 25x
The youngest is Kisii = 9x
Therefore, 25x - 9x = 16x
Substituting the value of x, we have;
x = 3; 16x = 16(3) = 48.
The age difference between the oldest and the youngest is 48.
