Answer:
C
Explanation:
The correct answer would be that in science, a theory is well supported by observations and/or experimental data.
Theories are usually derived from testing hypotheses. Untested statements from observations are referred to as theories. When hypotheses are tested using a series of independent experiments and found to be true, they become theories.
Hence, theories are well supported by observations and data in science. A theory remains accurate for as long as there are no contradictory findings to it. Theories can, however, be modified once there are data to back them up.
The correct option is C.
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

2.The fireplace has a glass screen. The side of the chair facing the fireplace gets warm because of_______________. Radiation
3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to _______________.Convection
hope this helps
Answer:
1) Conduction.
Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.
2) Radiation
The heat on the glass surface gets radiated into the chair which causes the chair to warm up.
3) Convection
The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.

How is static electricity created?
a. Two objects that are both positively charged repel each other and release
electric energy.
b. Two objects that are both negatively charged become attracted and create a
spark.
c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.
Answer:
d
Explanation:
So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.
Answer:
d. Friction between two objects causes a transfer of electrons from one object to the other.
Explanation:
If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.

True or False: Animals that eat meat benefit from plants.
Answer:
True
Explanation:
The animals they eat most likely eat (or eat something that eats) plants, making them a larger meal. If there were no plants, the wouldn't be herbivors, and without herbivors, no carnivors
Answer:
False
Explanation:
No animal is benefit from a plant not a Animal that eats meat anyway.
Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores. When animals eat both plants and meat, they are called omnivores.

The movement of water through a plant is caused by
Answer:
The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration) — this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.
Explanation:

Using the photosynthesis equation, predict how the rate of photosynthesis might change with variation in the following parameters (assuming that the plants is not receiving the maximum amount it can use):
a. The amount of light hitting a leaf
b. The availability of water
c. The amount of carbon dioxide in the atmosphere
d. The air temperature when water is limiting factor
Answer:
the answer is below
Explanation:
a) A plant process that changes sunlight into chemical energy. If there is less light the plant wont be able to function properly
b) Without enough water in the cells, the plants droop, so water helps a plant to stand. Water gives plants moisture to keep them alive.
c) If there is not enough CO2 the plant wont be able to photosynthesise as fastly as it usually does.
d) If the temperature is high and there is lack of water the plant is most likely to die. This is because it will be dehydrated.
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.

2. The allele for webbed hands (W) is dominant to normal hands (w). Complete a Punnett square
to predict the offspring should a heterozygous male cross with a heterozygous female.
a) Determine the genotype of each parent:
(parent one)
(parent two)
b) Complete the punnett square
c) Complete the ratios of the genetic cross:
d) What is the percentage that the offspring will have webbed hands?
e) What is the percentage that the offspring will have normal hands?
When a heterozygous male (Ww) crosses with a heterozygous female (Ww), the resulting offsprings possess genotypes WW, Ww, Ww, and ww.
What do you mean by Genotype?Genotypes may be defined as the ultimate combinations of the alleles of those genes which are selected for studies.
The genotypes of both parents are heterozygous i.e. Ww. The ratio of the complete genetic cross is 3:1.The percentage that the offspring will have webbed hands is 75%. (WW, Ww, Ww)The percentage that the offspring will have normal hands is 25% (ww).The Punnett square is attached below:
Therefore, it is well described above.

What are Monosaccharides?
Monosaccharides are the monomers of carbohydrates. It is the energy storage in the body. Carbohydrates provide energy in the form of glucose.
A monosaccharide is a type of simple sugar that serves as the foundation for more complex sugars like polysaccharides and oligosaccharides. Fructose, glucose, and ribose are some examples.
Monosaccharide is an etymology term that means "one saccharide." Saccharides are the basic building blocks of carbohydrates.

A landform is the set of forms that stand out on a plane or surface, being a feature of the landscape.
What is a landform?It is an outstanding texture of a surface that has different variations, among the most characteristic reliefs of the earth's surface are mountains, plateaus and plains.
These textures are presented in the form of irregularities and unevenness within a terrestrial or aquatic ecosystem, which provides a feature in a given landscape.
Therefore, we can conclude that a landform is formed by everything that protrudes from a flat surface or that modifies it, that is, it is the set of irregularities or features of a landscape.

Why does ice have the lowest density?
Answer:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
