Answer:
The specific order is phosphate-sugar-phosphate-sugar-phosphate.
Explanation:
The specific order in which nucleotides bond are the covalent bonds with phosphate group and '-OH group at specific places of nucleotides. When nucleotides are incorporated into DNA, adjacent nucleotides are linked by a covalent bond that is formed between the 5' phosphate group of one nucleotide and the 3'-OH group of another nucleotide. In this manner, each strand of DNA has a sequence of phosphate-sugar-phosphate-sugar-phosphate.

Two radioactive nuclei A and B are present in equal numbers to begin with. Three days later, there are 2.44 times as many A nuclei as there are B nuclei. The half-life of species B is 1.14 days. Find the half-life of species A (in days).
Answer:
2.23 days
Explanation:
Given that;
N=Noe^-kt
Where;
N= number of radioactive nuclei present at time =t
No= number of radioactive nuclei originally present
k = decay constant
t = time taken
But k = ln2/T
Where T is the half life of the radioactive nuclei
Hence;
NA= Noe^-ln2t/TA (1)
NB= Noe^-ln2t/TB (2)
But NA =2.44NB
2.44NB = Noe^-ln2t/TA (3)
NB= Noe^-ln2t/TB (4)
Divide (3) by (4)
2.44NB/NB = Noe^-ln2t/TA/Noe^-ln2t/TB
2.44 = e^-ln2t/TA + ln2t/TB
Taking natural logarithm of both sides
ln2.44 = -ln2t/TA + ln2t/TB
Given that TB = 1.14 days
TA= -ln2t(ln2.44 -ln2t/TB )^-1
TA= -(2.079) (0.892 - 2.079/1.14)^-1
TA = 2.23 days

The paternity test is done to test the real father of the child by comparing the child's DNA with the parents' DNA. It gives the result based on the DNA analysis, and here the test is shown in the gel electrophoresis. Gel electrophoresis shows the DNA segments of the child, mother, and three men, but the child DNA segments match the DNA segment of the dad 3. The child's DNA segments match with the mother, and the rest match with Dad 3, confirming that Dad 3 is the child's biological father.
Hence, out of them, one is the father, and the child's DNA matches that of the mother and Dad 3.

Normally, the clown fish readily swims among the tentacles of the sea anemones; the parrot fish avoids them. One hypothesis for the clown fish's apparent immunity is that they slowly build a tolerance to the sea anemone's toxin. A second hypothesis is that a chemical in the mucus that coats the clown fish prevents the nematocysts from being triggered.
Required:
Draw the graphs that supports the first, but not the second, of these hypotheses.
Answer:
The correct answer is - parrot fish - high, Clown fish - high.
Explanation:
According to the first hypothesis, the clown fish developed the immunity to the sea anemone's toxin so there would be a higher number of clown fish that swims among the tentacles of the sea anemones. The parrot fish avoids them also leads to a higher number of these fishes.
The correct graph that supports the first hypothesis that says that the clown fish's developed immunity build by them slowly, a tolerance to the sea anemone's toxin from tentacles of sea anemones.
this is science, please put a short desrciption for each of the sun's layers.
Answer: The core is the only place where nuclear fusion reactions can happen. In this broad zone, heat from the core cools dramatically, from between seven million K to two million K. Convection continues to be efficient in transporting heat until layers are reached where the density is so low that radiation from the hot up-flowing gas can escape directly into space. The lowest layer of the sun's atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun's energy is released as light. At other times, light from the chromosphere is usually too weak to be seen against the brighter photosphere. The chromosphere may play a role in conducting heat from the interior of the sun to its outermost layer, the corona. The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

Which of the following steps should be taken to
treat a patient suspected of going into shock?
Check all that apply.
Cover the patient with a blanket.
Provide food and water to the patient.
Have the patient get up and walk around.
Monitor heart rate and breathing every five
minutes
Answer:
The answer is the last one, "Monitor heart rate and breathing every five minutes".
Explanation:
Because it can determine when the patient will be going into shock.
The steps that should be taken to treat a patient suspected of going into shock are: Cover the patient with a blanket and monitor heart rate and breathing every five minutes.
Covering the patient with a blanket helps maintain their body temperature, as shock can lead to a drop in body temperature due to poor blood circulation and reduced oxygen supply to tissues. This simple measure can help prevent hypothermia and provide comfort to the patient during emergency care. Monitoring the patient's heart rate and breathing every five minutes is essential to assess their condition and detect any signs of deterioration.
Shock can lead to rapid and weak pulse, as well as shallow and irregular breathing. Regularly monitoring these vital signs allows medical professionals to identify early signs of worsening shock or other critical changes in the patient's condition. Prompt recognition of these changes can lead to timely intervention and improved outcomes for the patient.

In cattle, black coat color is dominant to white coat color. A farmer has a black male of undetermined genotype. How can the farmer determine the genotype of the black male?
Answer:
by looking at the offspring's phenotype
By observing phenotype of a cattle, the farmer can determine its genotype.
What do you mean by phenotype?Phenotype is an observable characteristics.Example: hair color, eye color, etc.It depends upon the genotype composition.What do you mean by genotype?"Genotype refers to the genetic makeup of an organism."It is given that black coat color is dominant and dominant allele for black color is denoted by B and recessive one is denoted by b.
So, in order to have black color the possible genotype would be Bb or BB.
If the offspring of the cattle have black color too, the genotype will be BB.
And if the offspring of the cattle have both black color as well as non-black color, the genotype will be Bb.
Hence, the farmer can determine the genotype of the black male by its phenotype.
