Answer:
(E) All of these choices are correct
Explanation:
Coral reefs are some of the most diverse ecosystems in the world. It is produced by Coral polyps and may occur as barrier, fringing, or atoll formations.
Coral reefs protect coastlines from storms and erosion, it is a rich source of job for local communities, and provides avenues for recreation. It is rich in food nutrients and can be used medicinally too.
It exhibits mutualism with photosynthetic algae called zooxanthellae. It supplies shelter and safety and materials needed by zooxanthellae for photosynthesis while it obtains nutrients and oxygen and waste removal mechanism from it.
B) Polymerases can only synthesize in the 5' to 3' direction
C) There are only enough dNTP's to support quick replication on one strand, so the other strand lags behind it
D) It is necessary to "slow down" one of the strands so that replication does not occur before cells have a chance to grow
Answer:
B) Polymerases can only synthesize in the 5' to 3' direction
Explanation:
The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.
b. The electron is replaced by electrons generated by the proton gradient.
c. electrons donated directly from plastoquinone at QA.
d. the splitting of water molecules at the manganese center.
e. oxidation of pheophytin. electrons donated from NADPH.
f. electrons transferred from plastocyanin.

Answer:
Nothing. There is absolutely nothing
Explanation:
Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.
Answer:
Explanation:
everything must match up inorder to find anyone accountiable
For forensic science, the Gas Chromatography-Mass Spectrometry (GC-MS) is highly reliable and accurate for identifying specific materials. In a case involving a paint chip, it accurately identifies the various elements and compounds in the paint and discriminates between different paint brands and types.
In the entire arsenal of forensic tests, one test stands out for its high reliability and accuracy in identifying specific materials: the Gas Chromatography-Mass Spectrometry (GC-MS). It has two main components: Gas Chromatograph, which separates the different components in a substance, and Mass Spectrometer, which identifies each of these components.
The GC-MS test is particularly effective when analyzing biological materials like blood, saliva, and even paint fragments. When dealing with a case involving a paint chip, for instance, GC-MS can not only identify the various elements and compounds in the paint but can discriminate between different paint brands and types, thereby increasing the probability of accurately matching the paint chip to a specific car.

Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer.
Only 10% of the energy consumed by an organism is available to be transferred to another trophic level due to the laws of thermodynamics and the inefficiency of energy transfer. This is known as the 10% rule.
The 10% rule states that energy is lost as heat during the process of respiration and metabolic activities, and only a fraction of the remaining energy is converted into biomass that is available as food for the next trophic level.
For example, if a primary producer (such as a plant) has 1,000 units of energy, only 100 units are passed on to the primary consumer (herbivore), and only 10 units are transferred to the secondary consumer (carnivore) in the next trophic level.
