Answer:
Explanation:
The woman with the question mark is not sure if she has the HD disease,
The mother had no history of the disease this means she is not a carrier of the disease but we are not sure of the fathers genotype.
If the father is a carrier in an homozygous dominant form(aa) and the mother does not have the disease her. gentotype is AA
A A ×aa
Aa Aa Aa Aa This means all their offspring will be Carrier of the disease because each parents contributes 50% of the gene their offspring is made of.
The probability that she is sick is 0% but she could be a carrot of the disease in an heterozygote form
If the woman who is a carrier (Aa)of the disease marries a man with no history of the disease(AA)
Aa ×AA
I
AA AA Aa Aa
The probation of their offspring being a carrier in heterozygous form is 50% while the probability of the offspring being dominant of the disease is 0%. Hence, she should not be afraid since her mother and husband who could have contributed to determining the gene of this offspring are not carriers of this gene the offspring are safe.

You are doing an experiment and plated E. coliin different medias. Media A has onlyglucose, B has only lactose, and media C has both glucose and lactose.You notice that some of the cultures grown in media C are metabolizinglactose. Which type(s) of mutation(s) could cause this to occur
Answer:
A. Glucose:
As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.
B. lactose:
In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts. The same result will be in all test except in the case of a mutant repressor.
C. glucose and lactose:
In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose. the given two cases :
Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B. The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.
Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.

A botanist has acquired a group of pea plants. All of the pea plants have yellow pea pods (the recessive form of this trait) except for one, which has green pea pods (the dominant form of this trait). The botanist decides to use a test cross to determine the genotype of the green pea pod plant for this trait. The botanist performed the test cross and found the following: 50% of the offspring had yellow pea pods and 50% of the offspring had green pea pods. Based on this information, what was the genotype of the initial green pea pod plant
Answer:
Hetezygous
Explanation:
The genotype of the initial green pod plant would be heterozygous.
Let pea pod color be represented by C (c) alleles.
First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.
CC x cc
Cc Cc Cc Cc
All the progeny will have Cc genotype with phenotypically green color. This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.
Now, let us assume that the genotype is Heterozygous, Cc.
Cc x cc
Cc Cc cc cc
50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. This is consistent with the result from the illustration.
Hence, the genotype of the initial green pea pod plant is heterozygous.
How N-formylmethionine (fMet) is only associated with the 5' AUG initiation codon and not with internal AUG codons, given that methionine in both cases in encoded by an AUG in the mRNA.
Answer:
Different transfer RNAs (tRNAs) selectively bind to N-terminal and internal AUG codons of bacterial polypeptides .
Explanation:
In prokaryotic organisms, N-formylmethionine (fMet) is coded by the start codon (AUG), thereby generating the most N-terminal residue of bacterial proteins. This residue (fMet) is a modified methionine amino acid that contains attached a formyl group to its amino group. Remarkably, it has been shown that formylmethionyl-tRNA only can bind to this initial AUG codon, while methionyl-tRNA binds to internal AUG codons.
What physiological alterations occur at both the vasculature and heart functioning level? (really stuck on this one, please help.)
Answer:
Most physiological alterations during aging and it is usually characterized by the deposition of a pigment called liposfuscin.
The valves of the heart also becomes stiff and thickened as a result of the pigment mentioned above. This makes the flow of blood slower than normal and contributes to cardiovascular diseases such as Stroke, high blood pressure etc.
Does specific heat also mean the amount of energy needed for cooling, or is it only energy for heating?
Answer:
yes it does
here is a more clearer explanation
Explanation:
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
Some other examples of specific heat capacities are:
Material Specific heat capacity (J/kg/°C)
Brick 840
Copper 385
Lead 129
Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature. Brick will take much longer to heat up and cool down. This is why bricks are sometimes used in storage heaters as they stay warm for a long time. Most heaters are filled with oil (1,800 J/kg°C) or water (4,200 J/kg°C) as these emit a lot of energy as they cool down and, therefore, stay warm for a long time.
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).

A study from the National Institutes of Health states that the human body contains trillions of microorganisms that make up 1% to 3% of the body's mass. Use this information to estimate the average mass of a microorganism.
Answer:
If the mass of the human body is 60 kg so the average mass of microorganism is 1.2 kg.
Explanation:
If we suppose the mass of human body is 60 kg and we know the percentage that is 1 to 3% so we will take the average microorganism mass of which is 2%. So by doing multiplication of 60 with 2 and then divided by 100, we get 1.2 kg. The reason for dividing by 100 is that the average mass present in percentage form so for converting the percentage into standard form we have to divide it by 100. So we conclude that in every human with a mass of 60 kg have 1.2 kg microbes present in their body.

These five concepts provide a modem interpretation of Mendelian postulates.
- Inheritance is governed by information stored in discrete factors called genes.
- Genes are transmitted from generation to generation on vehicles called chromosomes.
- Chromosomes, which exist in pairs in diploid organisms, provide the basis of biparental inheritance.
- During gamete formation, chromosomes are distributed according to postulates first described by Gregor Mendel, based on his nineteenth-century research with the garden pea.
- Mendelian postulates prescribe that homologous chromosomes segregate from one another and assort independently with other segregating homologous during gamete formation.
Based on these concepts, choose statements that correlate Mendel's four postulates with what is now known about genes, alleles, and homologous chromosomes.
Select the five correct statements.
a. Some gene pairs on nonhomologous chromosomes can aggregate after separation and mitosis or meiosis would stop.
b. Some genes have dominant and recessive alleles.
c. Unit factors occur in pairs.
d. Some possible gametic combinations are formed with higher probability if dominant alleles take part in meiosis.
e. During mitosis and meiosis, when chromosomes are visible in their characteristic shapes. members of a homologous pair have different sizes and exhibit opposite centromere locations.
f. Different gene pairs on non-homologous chromosomes will separate independently from each other during meiosis.
g. Alleles segregate from each other during gamete formation at anaphase
h. Dominant alleles can become codominant alleles during mitosis.
e. One gene pair separates independently from other gene pairs.
Answer:
b. Some genes have dominant and recessive alleles.
C. Unit factors occur in pairs.
e. During mitosis and meiosis, when chromosomes are visible in their characteristic shapes. members of a homologous pair have different sizes and exhibit opposite centromere locations
f. Different gene pairs on non-homologous chromosomes will separate independently from each other during meiosis.
g. Alleles segregate from each other during gamete formation at anaphase
Explanation:
Mendel's postulates of inheritance are: (1) Principles of Paired Factors (2) Principle of Dominance(3) Law of Segregation or Law of Purity of Gametes (Mendel’s First Law of Inheritance) and (4) Law of Independent Assortment (Mendel’s Second Law of Inheritance).
Each of these laws provide information on how inheritance of traits by offspring from parents occur.
Principle of paired factors:
A character is represented in an organism (diploid) by at least two factors. The two factors lie on the two homologous chromosomes at the same locus or position.
Principle of Dominance:
Dominant characters are those which always appear in every generatio whereas recessive characters may not appear in some generations e.g. F1 generation.
Law of segregation:
During the formation of gametes (egg or pollen), the paired genes separate or segregate randomly so that each gamete receives one or the other with equal likelihood
Law of Independent assortment:
During gamete formation, segregating pairs of unit factors (genes) assort independently of each other.
From the above consideration,
Option A is wrong because it doesn't correlate with the law of Independent assortment
Option B is correct based on the second postulate
Option C is correct based on the first postulate
Option D is wrong based on the law of segregation which assigns equal likely to gene separation
Option E is correct based on recent studies of genes
Option F is correct based on the law of Independent assortment
Option G is correct based on recent studies on genes
Option H is wrong because dominant genes remain dominant. Co-dominance occurs when allelic pairs are neither dominant nor recessive
Option 'e' is wrong because independent assortment occurs between pairs of genes with contrasting character not a gene pair having the same character where only segregation occurs.

Gonorrhea is a sexually transmitted infection (STI) caused by the diplococcus Neisseria gonorrhoeae, commonly called gonococcus (GC). This organism developed resistance to penicillin and tetracycline in the 1980s, after which fluoroquinolones were the recommended drugs for treating GC. Subsequent resistance to the fluoroquinolones has led to the current recommended treatment of injected ceftriaxone in combination with oral azithromycin. Although this approach continues to be effective, recent data from the CDC indicates that resistance to azithromycin is emerging.Fluoroquinolones act by inhibiting DNA gyrase, an enzyme involved in DNA replication. Resistance to this antibiotic is most commonly by a. due to a mutation in the gene that encodes RNA polymerase, an example of adaptive resistance. b. a change in the DNA gyrase target, an example of acquired resistance increased efflux of the drug from the target cell, an example of innate resistance. c. a change in the DNA gyrase target, an example of innate resistance. d. enzymatic modification of the ribosomal target, an example of innate resistance.
Answer:
The correct answer is option b, that is, a modification in the target of DNA gyrase, is an illustration of acquired resistance.
Explanation:
The activity of DNA gyrase gets inhibit by fluoroquinolones. The enzyme that combines with the DNA and prevents its supercoiling at the time of replication is termed as DNA gyrase. It is a heterotetramer, which is formed of two subunits of GyrA and two subunits of GyrB. Due to the mutation in gene gyrA, the development of resistance takes place in N. gonorrhea against fluoroquinolones.
Post mutation, gyrA exhibits lesser binding capacity with the fluoroquinolones, and thus, the development of resistance takes place within the bacteria against the fluoroquinolones. The phenomenon of the development of resistance taking place in any microbe against the specific antimicrobial agent for whom it was vulnerable before is termed as acquired resistance, thus, the given case is an illustration of acquired resistance.
