Answer:
B.
Explanation:
Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.
ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.
Hence, the correct option is "B".

Describe how protein functional groups can act as acid and base catalysts. How is it possible for a single amino acid side chain to function as both?
Answer:
By changing the transition state and pH of the medium
Explanation:
Enzymes are proteins that bind to their corresponding substrates at their active sites in order to form complexes that catalyze specific chemical reactions. A key feature of this process is the fact that both acid and base catalytic activities may be combined in the same reaction. The acceleration in the velocity of the enzymatic reaction due to the addition of acids and bases is known as acid–base catalysis, where the acid or base is not consumed during the reaction. For example, enzymes can partially transfer a proton to the medium, thus changing the transition state of the chemical reaction and also decreasing its pH.
After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.
Answer:
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )Explanation:
The three possible hypothesis for light not to turn on immediately after one on the switch are;
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )We test the first hypothesis, how?
We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.
To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.
As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.
The three hypotheses we can derive from entering a dark room, turning on a
light switch,and the light not coming on include
There may be no power source at that momentThe bulb may be faultyThe switch may be faultyA power source helps to provide energy to power up an appliance and where it is absent, the bulb won't light up.
A defect in the switch and bulb may also hinder the light from coming on as
the switch controls electric current flow while the bulb produces the light.

a. Autosomal dominant
b. Autosomal recessive
c. X-linked dominant
d. X-linked recessive
e. Mitochondrial
Answer:
e. Mitochondrial
Explanation:
This is a case of mitochondrial heredity so correct answer is e. Mitochondrial In this case, the mother transfers her mitochondria to her children. So the child is affected. The male does not pass this trait on to his children. We can see from the lineage that the mother has defective mitochondria so all their children will have defective mitochondria.

Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype. Two possible alleles for this gene are w for normal wings and wc for crinkled wings. Which of the following pieces of information would be helpful in predicting the wing phenotype of a male offspring from a cross?
a. look at the father's phenotype
b. know the mother's genotype
c. look at the mother's phenotype
d. know the father's genotype
Answer: d. know the father's genotype
Explanation: Butterflies can produce hundreds of offspring per cross. In a certain variety of butterflies, a maternally-imprintable gene is responsible for wing phenotype.
The option that would be helpful in predicting the wing phenotype of a male offspring from such a cross would be to look at the father's phenotype.
Imprinted genes can simply be defined as genes that are expressed in parent-of-origin specific manner and result from a chemical modification of DNAs. Such genes are differentially expressed depending on which of the two parents they are inherited from. Hence:
maternally-imprintable genes are only expressed when they are inherited from the father. paternally-imprintable genes are only expressed when inherited from the mother.Phenotype refers to the physical appearance or expression of a gene. Therefore, if a gene is maternally imprintable, looking at the phenotype of the father would be helpful in predicting the phenotype of the male child in case a cross happens.
Applying the same principle to the butterfly, it will, therefore, be helpful to look at the father's phenotype in order to predict the wing phenotype of a male offspring from a cross.
The correct option is A.

Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.
Answer:
Hydrophilic portions are outside and hydrophobic regions are inside
Explanation:
A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

The ion composition of perilymph is like that of interstitial fluid; high sodium and low potassium levels. If someone ruptured the vestibular membrane, the membrane between the vestibular duct (Scala vestibuli) and the cochlear duct (Scala media), what would be the effect of such a rupture on the concentration of potassium in the endolymph in the cochlear duct
Answer:
The concentration of potassium will decrease
Explanation:
The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e., without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.

Place the following materials in the order in which they are likely to fossilize. Begin with the material that is most likely to fossilize, and finish with the material least likely to fossilize.
1. mammal teeth
2. bones of an adult mammal quickly buried
3. bones of an adult mammal left on the surface
4. soft body parts of any animal
Answer: correct order--->
1)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Explanation:
Fossilization is the ability of an organism to be preserved and remain unaltered for a very long time. Through research , it has been found out that Harder parts of the body tend to remain preserved for a long time because they naturally have minerals deposited in them and may only be reduced, but the softer part or tissues do not get preserved for a long time because being made up of polymer can be disintegrated easily by natural biological and physical processes.
The order of which material will likely fossilize is
1.)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Reason,
--Teeth and bones biologically contain calcium but the teeth is more tougher and durable than the bone, Even when a body is decomposed, the teeth most times are not affected at all.
Bones of an adult mammal left on the surface will decompose faster than the one buried because of the biological (natural decomposing ) and physical processes(temperature, wind, sunglight, rainfall ) which will both act on it at the same time because of its exposure.
- soft body parts of any animals will decompose fastest as bacteria will feed on it immediately since it lacks minerals that can elongate preservation.
In humans, a type of blindness is due to a dominant allele (B). Normal vision is the result of a
recessive allele (b). Migraine headaches are due to a dominant allele (M), and normal (no migraines)
is recessive (m).
A male who is heterozygous for blindness and does not suffer from migraines marries a woman who
has normal vision and does not suffer from migraines.
Could they produce a child with normal vision who does not suffer from headaches? If yes, can the
probability of such a child be determined?
You must draw a Punnett square within the space provided to receive any credit for your answer!
Answer:
Yes, a child with normal vision who does not suffer from headaches can be produced.
The probability of producing such child from this cross is 1/2 or 50%
Explanation:
This question involves two distinct genes in humans. One coding for blindness and the other for Migraine headaches. The alleles for blindness (B) and Migraine (M) are dominant over the alleles for normal vision (b) and no Migraine (m).
According to the question, a male who is heterozygous for blindness and does not suffer from migraines will have the genotype; Bbmm while a female who
has normal vision and does not suffer from migraines will have genotype; bbmm. If these two parents are crossed, the following genotypes of gametes will be produced by each parent:
Bbmm- Bm, Bm, bm and bm
bbmm- bm, bm, bm, and bm
Using these gametes to construct a punnet square (see attached image), the following offsprings with genotypes; Bbmm and bbmm in the ratio 1:1 will be produced.
Bbmm (8/16) are offsprings with blindness and have no Migraine headache
bbmm (8/16) are offsprings with normal vision and have no migraine headache
Hence, this cross can produce a child with normal vision who does not suffer from headaches (bbmm). Also, the probability of producing such child is 8/16 or 1/2.
Genes, Chromosomes, and DNA Quick Check
If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? ( point)
There will be 16 total bases.
There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.
Answer:
There will be 8 adenine bases.
Explanation:
There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.
So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.
Hence, the correct answer is "There will be 8 adenine bases."

The idea that chromosomes orient themeselves randomly during metaphase I is ________________________. This leads to ___________________ combinations of genes.
Answer:
The idea that chromosomes orient themselves randomly during metaphase I is Independent Assortment. This leads to more combinations of genes.
Explanation:
During metaphase I, the pair of chromosomes align in the plate of the cell. In this step, the independent assortment takes place.
The independent assortment is the distribution of different genes into two gametes, is independent, because the distribution of the different genes, does not influence the distribution of the other genes. The independent assortment leads to new combinations of genes from the parental and maternal side, resulting in offsprings that do not look exactly like their parents.
PLEASE ANSWER QUICK!The Greek roots of the word prokaryote mean “before nucleus.” Describe the way that DNA is organized in prokaryotic cells without the help of a nucleus. How does this approach differ from the way that eukaryotic cells organizes their DNA
Answer:
Prokaryotic cells' DNA are located in the cytoplasm of the cell rather than in the nucleus, like in eukaryotic cells. DNA aids in protein synthesis and determines functions of the cell in cells, regardless of being within the membrane of a nucleus or not.

I hope this helps a little.
The word prokaryote in Greek means before kernel (nucleus). Unlike the eukaryotic cells, the nuclear material is located in the cytoplasm of the cell in a nucleoid.
What are the characteristics of prokaryotic cells?The prokaryotic cells are the primitive karyons that are defined by the lack of the true nucleus and organelles. Unlike the eukaryotes, the organelles lack the membrane that covers them but has a tough cell wall.
The prokaryotes include archaea and bacteria which are unicellular and microscopic organisms that are simple and have their genetic material organized into nucleoids in the center of the cell. They have the ability to live in harsh conditions.

On April 26, 1986, Reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded, releasing radioactive isotopes into the air. The majority of the isotopes that were released and spreading thousands of miles were of the element iodine. As a class, discuss what endocrine glands would be most affected and how it would become apparent in the nearby population.
Answer:
In the given case, the thyroid gland will be affected the most due to the exposure of the element iodine. For the synthesis of thyroid gland hormone, T3 and T4 iodine is required. As the exposure of the radioactive iodine element is taking place, therefore, it will result in the deterioration of the thyroid gland. Radioactive iodine is generally used in the treatment of hyperthyroidism.
However, in normal individuals, the exposure of the radioactive iodine element results in a decrease in the level of thyroid hormones below the normal level due to the destruction of the thyroid cells. The symptoms seen can be neck tenderness, swollen salivary gland, and loss in body weight.
The thyroid gland will be mostly affected in this case. The element Iodine is
the major precursor which is involved in the formation of two hormones.
