What is the best way to ensure that results of a study are generalizable to a population?
By making sure to use as many participants as possible
By making sure the results are significant
By making sure to use an equal number of men and women
By using random assignment
By using a random selection of people in that population
The best way to ensure that results of a study are generalizable to a population is by using a random selection of people in that population
The goal of every research experiment is to obtain results that are generalizable to a whole population.
This is achieved by the method of random selection. In random selection, members of the of the population are selected in such a way that is representative of the entire population. If for instance, I want to study a school having six classes which comprises of boys and girls. There are 700 students in the school and I need only 180 students to participate in a study whose results will be extrapolated to all the 700 students. I can decide to randomly select 15 boys and 15 girls from each class to participate in the study. This is an example of random selection.
In this way, the results obtained from the study is reflective of the whole population even though only a sample of the population actually participated in the study.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

Explain to your lab mate the health risk associated with consuming a diet low in vitamin K along with the ingestion of antibiotics over multiple days. How would the termination of antibiotic treatment help to remove this health risk?
Answer:
Vitamin K, a fat soluble vitamin is rich in green leafy vegetables,and also produced by bacterial in the intestine.
Its major function is blood clotting or arrest of bleeding to prevent blood loss.
Antibiotics especially with Cephalosporins,reduces Vit. K absorption in the intestine. Intake of these antibiotic kill the targeted bacterial together with the the bacteria which produces Vit. K in the intestine.
Hence when antibiotic is taken with low level of Vit, K the individual is prone to excessive bleeding or haemorrhage,because the concentration of the vitamins is further depleted.
If the medication is stopped,the condition will improve because the bacteria which produces Vt K can resumes the secretions,and its absorption will resume

DIHYBRID CROSSES
In all of the examples we have only been concerned with one trait. It is possible, however, to track the inheritance of more than one trait at a time. When one is investigating the inheritance of two traits at once the cross is called a dihybrid cross. Strictly speaking, a dihybrid cross is one between two individuals that are heterozygous for two traits, meaning that they are hybrids in two senses. For example, in humans eye color is determined by multiple factors, but if we compare only blue eyes to brown eyes, brown is dominant (R) and blue acts as a recessive allele (r). If a man heterozygous for both eye color and bent little finger has a child with a woman who also heterozygous for both traits, this would be a dihybrid cross. Which is/are possible genotypes for a person with bent little finger and blue eyes?
1. bbrr
2. BBRR
3. BBrr
4. Bbrr
Referring to the previous question, which is/are possible genotypes for a person with straight little finger and blue eyes?
1. bbrr
2. BbRr
3. Bbrr
4. bbRr
Answer:
Question 1: bbrr
Question 2: bbRr
Explanation:
To address the first question, the possible genotype for someone with bent little finger and blue eyes would be bbrr.
Since brown eye (B) is dominant over blue eyes (b), in order for the blue eye color to be expressed, it has to be in bb condition. The only option with bb genotype is option 1.
For the second question, the possible genotype for a person with a straight little finger and blue eyes would be bbRr.
Blue eye genotype is bb as explained in the first question while straight little finger would be Rr since the bent little finger has been represented by the genotype rr in the first question.

a) There are three nucleotide in each codon, and each of these nucleotides can have one of four different bases. How many possible unique codons are there?
b) If DNA had only two types of bases instead of four, how long would codons need to be to specify all 20 amino acids?
Answer:
Explanation:
There are 64 possible codons to be specified for, If we have three nucleotides with 4 bases the set of all combinations can encode
4x4x4 = 64 amino acids
This will give 64 different combinations of four nucleotides
If we have 2 bases with 4 nucleotide we have a possibility of having 16 codons specifying for 20 amino acid.
If we have 2 nucleotides with 4 bases the set of combination is
4×4 = 16 amino acids of four nucleotides

Production of maltose, by ___________________ condensation, dehydration, hydrolysis) of starch, in the presence of amylase, can be detected by colorimetric assay.
Answer:
Hydrolysis.
Explanation:
Maltose is produced by hydrolysis of starch, in the presence of amylase, can be detected by colorimetric assay. As per the assay of hydrolysis of starch we have concluded from the test of enzyme activity of amylase is that maltose being a reducing sugar which reacts and reduces the DNS (3,5-dinitrosalicylic acid) that is basically a pale yellow colored alkaline which results after some minutes into 3-amino,5-nitrosalicyclic acid which orange red colored alkaline after heating.
Identical twins are formed from one fertilized egg, but fraternal twins form from two different fertilized eggs. Apply your knowledge of mitosis and meiosis to explain the genetic differences between identical and fraternal twins.
Answer:
Identical twins share the exact same DNA while fraternal twins do not.
Explanation:
Mitosis is the type of cell division that results in 2 individual cells that have the exact genetic material.
Meiosis is the division of reproductive cells, eggs and sperms, which results in new cells with half the amount of genetic material and that makes them unique.
Identical twins are twins developed from a single egg that has been fertilized with a single sperm, meaning they have the same DNA.
Fraternal twins are twins from two different eggs that have been fertilized by two different sperms and grow in the womb at the same time with no additional cell division. So they have different DNA's.
I hope this answer helps.
The formation of fraternal twins takes place when the female generates two eggs and identical twins takes place when the female generates one egg and the zygote divides into two spontaneously.
• In identical twins case, the zygote goes through cleavage, that is, cell division by mitosis, when embryo is at the stage of two cell.
• The separation of two blastomeres may take place and then each act as an independent zygote.
• This each dissociated blastomere give rise to a novel independent individual.
• The production of both the organisms takes place due to mitosis, thus, both would possess identical genetic makeup and are known as identical twins.
• Identical twins would be either males or would be either females.
• In case of fraternal twins, the female generates more than one eggs. And all the eggs get fertilized independently by the sperm.
• Thus, formation of two or more zygotes takes place, and each zygote give rise to new offspring.
• These offsprings possess distinct genetic combinations, and such offspring are known as fraternal twins.
• They are produced sexually, and fraternal twins can possess different genders as they do not possess similar genetic recombination.
Thus, identical twins is formed from one egg and the zygote gets divide into two, while fraternal twins formation takes place when two eggs are generated by the female.

Without this, many cycles such as the water cycle and photosynthesis would not exist. What could all these cycles not exist without?
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.
In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.
During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.
From the explanation above, it can be deduced that the absence of the sun/sunlight will prevent the two cycles from existing.
