1. Compare aerobic respiration and fermentation in term of:
a. Which process obtain less energy from glucose?
b. What are end products of fermentation and respiration process?
a) Fermentation obtain less energy from glucose .
b) The end product of fermentation are alcohol and carbon dioxide . end product of aerobic respiration is carbon dioxide , water and energy .
What is fermentation ?In anaerobic processes like fermentation, glucose can still be converted to energy even in the absence of oxygen.
In bacteria, yeast cells, animal muscles, and other tissues, fermentation takes place. The process by which glucose is broken down is anaerobic.
Cellular respiration refers to the respiration that takes place at the smallest scale possible within our bodies, i.e. within the cell. It happens whether oxygen is present or not. Any type of cellular respiration starts with glycolysis, the final step of which produces the 3-C molecule pyruvic acid.
Fermentation is one of the two main methods that various cells handle this pyruvate.
What is aerobic respiration ?Food glucose is transformed into energy during an aerobic respiration, a biological process that takes place with the presence of oxygen. The following is the chemical formula for aerobic respiration:
Oxygen 6(O2) + Carbon 6(CO2) + Water 6 (H2O) + Energy = Glucose (C6H12O6) (ATP)
The chemical equation above states that energy is released by breaking glucose molecules with the aid of oxygen gas. As the by-products or final products of the chemical reaction, energy, water molecules, and carbon dioxide gas are released.
The breakdown of the glucose molecule releases 2900 kJ of energy, which is then utilized to create ATP, or adenosine triphosphate, molecules that the body uses for a variety of functions.
All multicellular organisms, including animals, plants, and other living things, engage in an aerobic respiration process.
The stomata, which are located in the epidermis of a plant's leaves and stem, allow oxygen gas to enter plant cells during the respiration process in plants. All green plants produce their food and release energy through the process of photosynthesis.

OB.
between the hydrogen atoms of two water molecules
O C.
between the oxygen atoms of two water molecules
Between the hydrogen atoms of two water molecules the two atoms of water are hydrogen bonds are formed
Hydrogen Atoms and Water MoleculesTwo hydrogen (H) atoms and one oxygen (O) atom make up the three atoms that make up a water molecule. Because of this, water is occasionally abbreviated as H2O. In the case of water, hydrogen bonds occur between adjacent water molecules' hydrogen and oxygen atoms. A bond called a hydrogen bond is produced by the attraction between individual water molecules. The molecular makeup of water holds the key to understanding its chemical behavior. A water molecule has a bent overall structure and is made up of two hydrogen atoms bound to an oxygen atom. This is because the oxygen atom additionally carries two pairs of unshared electrons in addition to making bonds with the hydrogen atoms.

What causes cell division?The two distinct ways that cells divide are called mitosis and meiosis. Typically, mitosis—the process of creating new body cells—is what is meant when the word "cell division" is used. The process of cell division that yields sperm and egg cells is known as meiosis.
What is the proper order for the processes in cell division?There are six stages in this cycle: prophase, prometaphase, metaphase, anaphase, and telophase . Because cytokinesis is the final physical cell division after telophase, it is also referred to as the sixth stage of mitosis.
What mechanism divides cells?Cells divide in two different ways, mitosis and meiosis. The procedure of mitosis, which produces new body cells, is often when "cell division" is referred to. Meiosis is the name for the cell-division procedure that results in sperm and egg cells

2a. The enzyme called Pheide a Oxygenase (PAO) catalyses the degradation of chlorophyll. Mendel’s I gene (yellow peas) codes for this enzyme. If this gene is mutated, what will happen to the pea colour? 2b. What was discovered when looking at the PAO levels between heterozygous and homozygous plants? 2c. Gibberellin is a plant hormone that promotes the elongation of plant stems. It is produced in a series of reactions requiring an enzyme coded for by a specific gene. If this gene is isolated, and mutated, how will this affect the height of the plant?
The answers for the alternatives are:
a) The PAO enzyme catalyses the degradation of chlorophyl, when the gene for the production of PAO is mutated, the pea plant won't have a functional PAO, being the chlorophyl in that plant not degradated, in consequence the pea plants will remain green and not turn out yellow like their gene stipule by Mendel's Law.
b) When made the comparison between heterozygous and homozygous for PAO enzyme in plants, it was discovered that heterozygous will have half as much PAO as a homozygous dominant for the PAO gene, since the lower enzyme level is enough to produce PAO for the plant degradate chlorophyl.
c) If the gene for the enzyme related to promote elogation of plant stems is mutated, it is expected that the height of the plant will be lower than with the specific gene working, because the reactions and gibberellin production and distribution are directed affect by that genetic modification.

The amount of iron oxide formed from the reaction will be 179.7 g.
Stoichiometric problemFrom the balanced equation of the reaction below:
[tex]4 Fe + 3 O_2 -- > 2 Fe_2O_3[/tex]
The mole ratio of Fe to [tex]O_2[/tex] is 4:3
Recall that: mole = mass/molar mass.
Mole of 112 g iron = 112/56 = 2 moles
Mole of 24 g [tex]O_2[/tex] = 24/32 = 0.75 moles
Thus, [tex]O_2[/tex] appears to be the limiting reactant. Iron is in excess.
Mole ratio of [tex]O_2[/tex] and [tex]Fe_2O_3[/tex] = 3:2
Equivalent mole of [tex]Fe_2O_3[/tex] = 0.75 x 3/2 = 1.125 moles
Mass of 1.125 moles [tex]Fe_2O_3[/tex] = 1.125 x 159.69
= 179.7 grams
In summary, if 112 g of iron combines with 24 g of oxygen, 179.7 g of [tex]Fe_2O_3[/tex] will be produced.

When the body of the mass increases the acceleration decrease.
According to newton's second law of motion Force equals the rate of change of momentum. F = m * a . It can also be represented as [tex]\frac{f}{a} = m[/tex]
where F = Force
m = mass of an object
a = acceleration
Mass and acceleration are inversely related, if the mass of an object increases the acceleration of the body decreases, and vice versa.

REAL ANSWERS ONLY! NO LINKS!!!!!
Answer:
(1) topoisomerase I un-supercoils the DNA in the cytoplasm
(2) single stranded binding proteins bind to the separated DNA to keep it from reforming the hydrogen bonds while it is being replicated
(3) the RNA polymerase "primase" lays down a short stretch of RNA (RNA primer)
(4) DNA polymerase III starts adding new nucleotides to the 3’ ends of the RNA primer on both the leading and lagging strands
(5) Once the entire chromosome has been copied DNA polymerase I removes the RNA primers and replaces them with deoxyribonucleotides. DNA polymerase I has exonuclease activity in the 5’ – 3’ direction, so it can remove and then replace nucleotides as it moves down the piece of DNA.
(6) DNA ligase comes in to hook together any gaps in the nucleotides so that the newly synthesized DNA is one continuous strand and catalyzes the connection between the 5’ phosphate group and 3’ hydroxyl group
(7) The nitrogenous bases reform hydrogen bonds to "re-zip" and then DNA gyrase helps the supercoils to reform.

give an example of when a lions roar being silent would be advantageous in a population of lions.
Solution:
Roaring is an integral component of African lion ecology as it facilitates social cohesion and territorial defense. In fact, as both a social and territorial species, communication is essential to lion ecology and roaring is perhaps the most important vocal cue.
An example of the importance of the roar would be that lions can discriminate between resident and non-resident lions, determine the relative risk of encountering unfamiliar lions, and detect the ratio of residents to intruders from roaring choruses.
