Explanation:
Edxcel alevel biology past papers: some of the blood plasma of individuals who have survived infection wtih Ebola can be collected. This can be used in the treatment of individuals currentlty infected with Ebola. Explain why the blood plasma from survivors can be used to treat new cases of Ebola infection.
Answer:
This was the only treatment options adopted for the Ebola in 1995 in the Democratic Republic of Congo. The assumption was that immune response is generated by the virus in the WBC of the infected individuals. These response produce antibodies.
A total if 8 patients were transfused with these blood contained antibodies, but one of these died, the remaining 7 patients survived.
The antibodies were believed to have multiplied(produced b-cells) to neutralize the Ebola virus(antigens) and to ensure the survival of the patients

Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.
how does water boiling on a stove represent all 3 types of heat transfer
Answer:
For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

What is the role of creatine kinase in the myofibril?
Answer:
Creatine kinase (CK) has several functions in cellular energy metabolism. It catalyzes the reversible transfer of high-energy phosphate from ATP to creatine, facilitating storage of energy in the form of phosphocreatine.
The evidence suggests that the myofibrils' creatine kinase is sufficient to maintain typical tension and relaxation, typical Ca sensitivity, and typical kinetic properties.
What is myofibril?On the long axis of the myocytes, groups of myofibrils—long contractile fibers run parallel to one another (long single multinucleated cells that combine to form the muscle).
On the cell's long axis, the myocytes are situated next to one another in parallel.
Creatine, a molecule found in your muscle cells that aids in the production of energy by your muscles, needs a phosphate group added to it by CK.
Creatine becomes the high-energy molecule, phosphocreatine, which your body uses to produce energy, when CK attaches phosphates to it.
According to the research, the myofibrils' creatine kinase is enough to keep their regular kinetic features, like tension and relaxation and Ca sensitivity, in place.
Thus, this is the role of creatine kinase in the myofibril.

The genetic material is arranged differently in the cell of bacteria compared with animal and plant cells.
Describe two differences.
Answer:
unlike bacteria cells, plant and animal cells both have membrane. Bacteria cells lack membrane. Bacteria multiple by binary fission.
Animal and plant cells contain linear chromosomes. Bacteria have one circular chromosone and no nucleus. Plasmids carry genetic material in some bacteria.
What is bacteria?Bacteria are unicellular organisms that are very tiny. Bacteria can be found practically anywhere on Earth and play an essential role in the ecosystems that exist there. Some animals are able to survive in environments with both high temperatures and high pressures.
Both plant and animal cells store their genetic material in the form of chromosomes, which are linear structures. Bacteria do not possess a truly organized nucleus and instead contain a single chromosone that is round. Plasmids are tiny circular pieces of genetic material that can be carried by some bacteria. These plasmids carry additional genetic material.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

How many valence electrons does carbon have? Is this atom satisfied? Explain.
Answer:
4 valence electrons
Explanation:
Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge.
Answer:
Carbon has 4 valence electrons. It is not satisfied. To be satisfied, it needs to covalently bond with 4 electrons to achieve octet (8 valence electrons).

a. They are commercially important.
b. They are used to replace native species.
C. They are used for restocking programs.
d. None of the above
Answer:
D
Explanation:
All of the given reasons are reasons that nonnative species are reared outside their native ecosystems. The correct option is D.
What are nonnative species?Non-native species are animals, plants, and other organisms that do not develop natively in a region but are instead introduced through intentional or unintentional human activity.
Non-native species, unlike invasive species, do not necessarily threaten or threaten the existence of other species within the ecosystem.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.
They are employed in restocking efforts, to replace native species, and for commercial purposes.
Thus, the correct option is D.

Answer:
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.
Explanation:
The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.
What is diffusion?Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.
There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.
Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.
