Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. The pH in the intermembrane space is higher than the pH in the mitochondrial matrix. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. Hydrogen ions are actively transported out of the mitochondrial matrix. Hydrogen ion concentration is higher in the intermembrane space than in the mitochondrial matrix. Energy is generated as a result of the difference in hydrogen ion concentration between the mitochondrial matrix and the cytoplasm.

Explanation:
Why is the "dorsal-ventral" axis not synonymous with the "posterior-anterior" axis in the whole human nervous system?
Answer:
The ventral side is towards the belly side
The Dorsal side is back to the belly side
Anterior is Before the belly side
Posterior is after or coming after to the belly side.
Explanation:
The ventral side is associated with the animal or a person belly side which related to the organism digestion and respiratory organs.
The anterior is the before or in front of side position which is associated with the front line of an organism.
The posterior side is related to the after side or it is opposite to the anterior position of an organism.
It is depend on the organism position, that these sides are related to each other in some instances. In some cases these are orthogonal in some times.
A particular protein (Vac8) found in yeast has this N-terminal sequence, Met-Gly-Ser-Ser-Cys.... The corresponding DNA sequence in the coding strand is 5' ATG GGC TCA TCG TGC.... If the DNA sequence is mutated to 5' CTG GGC TCA TCG TGC..., what will happen to this VAC8 gene? (in RNA, CUG codes for Leu)
Answer:
The protein will not be synthesized because this point mutation produces the loss of the start codon (substitution of Met by Leu).
Explanation:
The mutations are changes in the DNA sequence that have diverse effects on protein synthesis. A mutation in the start AUG codon may lead to the reduction and even the elimination of protein synthesis. In consequence, this type of point mutation is usually referred to as 'start-loss mutation'.
This requires you to use all the things we have learned in this chapter. 1.55 grams of Carbon disulfide
is added to 2.83 grams of Oxygen to form Carbon dioxide and Sulfur dioxide. If the reaction yields
1.1 grams of the Sulfur dioxide what was the percent yield?
27%
14%
Ο Ο Ο Ο Ο
74%
42%
O 63%
Answer: The percent yield is, 42%
Explanation:
To calculate the moles :
[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]
[tex]\text{Moles of carbon disulphide}=\frac{1.55g}{76g/mol}=0.020moles[/tex]
[tex]\text{Moles of oxygen}=\frac{2.83g}{32g/mol}=0.088moles[/tex]
The balanced chemical reaction is:
[tex]CS_2+3O_2(g)\rightarrow CO_2+2SO_2[/tex]
According to stoichiometry :
1 moles of [tex]CS_2[/tex] require = 3 moles of [tex]O_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] will require=[tex]\frac{3}{1}\times 0.020=0.060moles[/tex] of [tex]O_2[/tex]
Thus [tex]CS_2[/tex] is the limiting reagent as it limits the formation of product and [tex]O_2[/tex] is the excess reagent.
As 1 mole of [tex]CS_2[/tex] give = 2 moles of [tex]SO_2[/tex]
Thus 0.020 moles of [tex]CS_2[/tex] give =[tex]\frac{2}{1}\times 0.020=0.040moles[/tex] of [tex]SO_2[/tex]
Theoretical mass of [tex]SO_2=moles\times {\text {Molar mass}}=0.040moles\times 64g/mol=2.56g[/tex]
Actual mass of [tex]SO_2[/tex] = 1.1 g
Now we have to calculate the percent yield
[tex]\%\text{ yield}=\frac{\text{Actual yield }}{\text{Theoretical yield}}\times 100=\frac{1.1g}{2.56g}\times 100=42\%[/tex]
Therefore, the percent yield is, 42%
he effect of autonomic fibers on target cells is _________. The effect of somatic fibers on target cells is __________.
Answer:
The effect of autonomic fibers on target cells is excitatory or inhibitory
The effect of somatic fibers on target cells is always excitatory.
Explanation:
The autonomic fibers is a part of peripheral nervous system that controls the involuntary actions of internal organs and glands like heart and intestines.
It's effect are excitatory or inhibitory because reflexive and involuntary manner. It helps to maintain homeostasis (internal stability and balance) through the coordination of various activities such as hormone secretion, circulation, respiration, digestion and excretion. This system control fight to fight response in the body incase of danger.
This system operate in opposite" actions where one system activates a physiological response and the other inhibits it.
The somatic fibers are part of the peripheral nervous system that help transmit sensory information and motor information. They are made up of nerves that connect to the skin, sensory organs, and all skeletal muscles.
Somatic neurons are excitatory neurons because excite their target postsynaptic neurons or target cells causing it to function..

R represents the allele for red hair, and r represents the allele for white hair.
Which best describes this inheritance pattern?
A) Incomplete dominance because the intermediate form of the trait is chosen
B) Co-dominance because the intermediate form of the trait is chosen C) Incomplete dominance because the offspring display alleles for both hair colors
D) Co-dominance because the offspring display alleles for both hair colors
Answer:
A
Explanation
the red haired trait is dominant over the white haired trait. and the results are all red haired offspring. therefore its incomplete dominance
The correct option is D) Co-dominance because the offspring display alleles for both hair colors.
What is Co-dominance?Co-dominance refers to a phenomena, in which both alleles are simultaneously expressed in the heterozygote.
Incomplete dominance is closely related to Co-dominance in which phenotype of the progeny is intermediate of the parent phenotype.
Here, the red haired trait is dominant over the white haired trait and still both alleles are simultaneously expressed in the heterozygote of the offspring with red and white hair traits, thus, the Co-dominance best describes this inheritance pattern.

Answer: The attachment listed some cell organelles,although there isn't a specific question on then but am going to be defining each of them and state their functions as well.
1. The Nucleus; The is command centre of the cell, it is made up of nuleolus, chromosomes, nucleoplasm,nuclear envelope and nuclear lamina.
it contains the genetic/hereditary materials that the cell is made up of.
The Nucleus plays a great role in the control of growth and development of the cell.
The nucleus also coordinates some of the the activities of the cell like cell division and protein synthesis.
2. Cytoplasm; The cytoplasm is one of the cell organelles,it is the liquid portion of the cell,it consists of cell contents between the plasma and the cell membrane. The fluid cytoplasmic material is where many cell organelles are found/suspended fluid. Most activities carried out by the cell occurs in the cytoplasm.
3. Endoplasmic Reticulum; The Endoplasmic Reticulum is one of the cell organelles that have the structure of a network of flattened sacs and tubules and play a crucial role in plant and animal cell. Rough endoplasmic reticulum has ribosomes attached to the cytoplasmic side of the membrane and the smooth endoplasmic reticulum lacks attached ribosomes in them thus giving it the smooth appearance.
The Endoplasmic Reticulum functions in the production, processing, and transport of proteins and in and out of the cell and also the production of lipids.
4. Golgi Body; One of the plant organelles that plays a role in the sorting and organizing the proteins produced and processed by the Endoplasmic Reticulum. these proteins are sorted and packed in vessicles to be used by the body.
5. Mitochondria; (a double membrane organelle). It is otherwise known as the powerhouse of the cell,it produce/generate energy in the form of ATP needed for cellular respiration. These energy produced is used for other cellular metabolic activities.
6. Lysosome (Animal) Chloroplast (Plant); Lysosomes are found in most animal cells, they function by digesting good and garbage,they contains acids that aids this function in the stomach of the cell and when the lysosome is diseased or explodes,the cell stops functioning.
The Chloroplast on the other hand is found in the cells of plants and algae,they play a crucial broke in photosynthesis by capturing the energy from the sun and turning the captured energy into usable forms like sugar,glucose and other organic molecules.
7. Cell Membrane; The cell membrane is the cell organelle that forms a boundary between the cell and the sorounding environment.
The cell membrane as well controls the movement of cellular materials in and out of the cell.
8. Nucleolus; The nucleolus is one of the cell organelles where ribosomes are made. The ribosomes are small grain-shaped organelles that make protein and they are found in the surface of rough Endoplasmic Reticulum. Nucleolus are small and round in structure and are found in the nucleus,
9. Vacoule (Plant Cells) Centrioles (Animal Cells); The vacoule is a storage chamber(reservoir) for wanted and unwanted materials in the cell, the vacoule is found within the cytoplasm and it is enclosed by a membrane that typically contains fluid.
The centrioles on the part of the animal cell is a cell organelle that has a structure of a two hollow cylinders,ring of microtubules next to each other(the centrosome).the centrioles are located just outside the nucleus of the cell.
Centrioles function by producing the mitotic spindles for cell division, and also assisting to pull chromosome pairs apart to opposite end of the cell during cell division.
10. Cell Wall; A protective semi permeable rigid outer layer of nonliving material that surrounds the cells of plants and some other organisms.
The cell wall houses the organelles of the plant cell.
The cell wall functions by giving the cell strength and structure,it's semi permeable nature filters and selectively allows certain materials in and out of the cell.

Explanation:
This element is a gas that is found in both nucleic acids and in amino acids, important building blocks of life. What is it? A. Nitrogen B. Sulfur C. Oxygen D. Carbon My answer is: A) Nitrogen
Answer:
Yes, your answer, nitrogen, is correct (the most appropriate option). However, oxygen is also a correct option.
Explanation:
Nitrogen exists on its own as a diatomic gas. However, it exists as organic nitrogen in nucleic acids such as DNA and RNA (as part of their nitrogenous bases) and in the amino (--[tex]NH_{2}[/tex]) group of amino acids.
Do note that a case can also be made for oxygen as a right option: like nitrogen, it exists as a diatomic gas and can be found in both nucleic acids and in the carboxylic group of amino acids.
Sulfur is not an appropriate option as nitrogenous bases (and nucleic acids) to the best of my knowledge do not contain sulphur although some amino acids like cysteine do.
Carbon is not also an appropriate option because elemental carbon does not exist in gaseous form even though it can be found in both nucleic acids and amino acids.

Answer:
The answer is
2. magnetism and fluorescence
Explanation:
The other properties mentioned are common properties that are used to identify all minerals. As you can see, hardness, color and fracture are common properties that cut across all minerals. Magnetism and fluorescence however, are not very common and are found in only a few special minerals. That is why they are considered special properties.
Hope this helps!
magnetism and fluorescence are considered two of the special properties that are used to identify certain minerals. Thus option B is correct.
what are the properties to identify an object ?
Minerals are the chemical compound which has a well -defined composition and a specific crystal structure and occurs naturally in the pure form.
If a compound occurs naturally in different crystal form then it is referred as a different mineral. The chemical composition of a mineral varies depending on the presence of small impurities which are present in small quantities.
Some minerals can have variable proportions of two or more chemical elements which occupy equivalent position in the crystal structure; it has variable composition which is split into separate species.
minerals include color, streak, luster, specific gravity and cleavage as their physical properties, shows no magnetism. Basically magnetism is the physical property of the minerals, magnetism does not have these elements. thus, have no magnetism called diamagnetic. Examples of diamagnetic are quartz, apatite and calcite.
