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?
Answers
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.

Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
Answers
Answer:
Explanation:
Benefits
Animals will not depend on plant source again for their food but have it produced directly by themselves because photosynthesis will allow animal produce their own food
Animal will get a direct source of energy for their activities. Energy is derived from food consumed after the food has been broken down in the body system of animal. Animal photosynthesis will give animals access to direct source of energy as the product their food.

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
Answers
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.

Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.
Answers
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 idea that chromosomes orient themeselves randomly during metaphase I is ________________________. This leads to ___________________ combinations of genes.
Answers
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.
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.
Answers
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.

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.
Therefore, the eukaryotes and prokaryotes differ in the arrangement of the genetic material.

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
Answers
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.

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.
Answers
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."
