1. The graph below shows rate of reaction data for 2 different enzymes. One of these enzymes is found in the stomach, the other is found in the mouth.a) Both these enzymes have the same optimum pH, TRUE or FALSE?2. Explain, in terms of bonding, why the rate of reaction gradually falls once the pH increases above the optimum rather than denaturing straight away.

Answer: false? i think it is a population but its technically a colony

Explanation:

technically yes it is a population but for an exact answer its a colonie and if it more than one colony then it's a society if there are more than one species of creature then it is an ecosystem (i think)

Explanation:

Trees support the lives of many large organisms. Apple trees are used for food, shelter, and sites for reproduction. Deer also use the trees for consuming the apples.

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.

Plowing is a farming practice, that creates as its name says, contour lines, these lines are characteristic because they are placed perpendicular to the slope, for this reason, they are a method used to prevent erosion and retain water.

With this information in hand, we can see that option A is not correct because the use of plowing is related to soil loss and not to soil richness per se. Option B is not correct either because the use of insecticides is more related to the type of crop and surrounding vegetation cover. Option C in this case is the correct answer, it is used to reduce erosion and sediment pollution because helps retain soil. Finally, option D is not correct because this method is not related to livestock.

Answer:

Explanation: The photic zone, is the surface layer of the ocean that receives sunlight. The uppermost 80 m (260 feet) or more of the ocean. Plus the coral reef tends to be quite illuminated at times. In addition to this, the coral reef is built out of many layers of dead cnidarians.

Sex cell is a gamete cell, used in sexual reproduction. which means that it will have half of the amount of chromosomes that other cells does, so it can merge with another sex cell and create a daughter cell (that is somatic) that has genetic material from both sex cells.

Somatic cell is every other cell, building our organs and our body, and it contains twice the amount of genetic material that's present in sex cells.

Therefore, we can match the examples as follows:

a. white blood cell - SOMATIC CELL

b. sperm - SEX CELL

c. egg (ova) - SEX CELL

d. hepatocyte (liver cell) - SOMATIC CELL

e. epithelial (skin) cell - SOMATIC CELL

If the intron is capable of catalyzing the reaction that removes introns from larger RNA molecules, that intron is acting as an enzyme (c). That's because enzymes are the type of molecules capable of catalyzing reactions.

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.

Basically when you put more weight on a moving the motion or the movement of the body decreases due to the heavyweight.

Ribosomal subunits are made by the nucleolus. The

Ribosome contains two different subunits, both of which are required for translation. The small subunit (“40S” in eukaryotes) decodes genetic messages, while the large subunit (“60S” in eukaryotes) catalyzes the formation of peptide bonds.

In eukaryotes, rRNA is assembled into four strands on the ribosome and into three strands in prokaryotes. Eukaryotic ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and bind four rRNA strands to form the two ribosomal subunits (small and large) that make up the complete ribosome. The

Ribosomal units exit the nucleolus through the nuclear pore and enter the cytoplasm where they bind for protein synthesis. When no protein is produced, her two subunits of the ribosome separate.

The nucleolus manufactures ribosomal subunits. The ribosome contains two different subunits, both of which are required for translation.

Both of the two distinct subunits found in ribosomes are necessary for translation. The big subunit (designated the 60S in eukaryotes) catalyzes the synthesis of peptide bonds, while the small subunit (designated 40S in eukaryotes) decodes genetic signals.

The ribosome assembles rRNA into three strands in prokaryotes and four strands in eukaryotes. The nucleolus is where eukaryotic ribosomes are made and put together. The two ribosomal subunits (small and big) that make up the entire ribosome are formed when ribosomal proteins bind four strands of rRNA inside the nucleolus. The

The given reaction represents the process of photosynthesis.

Photosynthesis is the process by which plants synthesize their food. During photosynthesis, plants use carbon dioxide and water in the presence of sunlight to manufacture glucose (sugar) and liberate oxygen.

The reaction for photosynthesis can be given by the following equation:-

6CO2 + 6H2O + light ----> C6H12O6 + 6O2

Photosynthesis generally occurs in the leaves (which contain chloroplasts) of plants. The gaseous exchange takes place by means of pores called stomata, which are present in the leaves. Water is taken by the plants through the roots with the help of a vascular system. The chlorophyll pigment that is present in the chloroplasts within leaf cells is responsible for capturing sunlight.

Explanation:

Answer:

They remove large quantities of carbon dioxide from the atmosphere and use the carbon atoms to build organic molecules. Without Earth's abundance of plants and algae to continually suck up carbon dioxide, the gas would build up in the atmosphere.

Explanation:

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.

All of the suggested answers fit the question.

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.

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.

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

The amount of iron oxide formed from the reaction will be 179.7 g.

From 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.
