Answer:
Explanation:
1.Hot coffee is stirred with a spoon, the spoon gets hot due to _______________.conduction
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.

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.

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.

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.
Which phrase describes a landform?
a feature of the landscape
the shape of land in an area
a process that shaped Earth's surface
the difference in elevation between the highest and lowest points
Which phrase describes a landform
Answer:
A) a feature of the landscape
Explanation:
got it right on edge
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.

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.

Certain materials are needed by the mitochondria to make energy. Which of the following is most responsible for getting the
materials into the cell?
O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria
Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

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
