"Some plants called epiphytes, or air plants, have adapted to get nutrients from the air.
Some examples of epiphytes in rainforests are mosses, lichens, and orchids. Although
they often live on other plants, they don't take any nutrients from the other plants-they
get what they need straight from the air with special root systems.
There are also some plants called parasitic plants. They grow on other plants, their host
plants. Parasitic plants actually DO take nutrients from their host plants."
Why might the author have capitalized the word "DO"?
A. to point out a similarity
B. to make a contrast
C. to summarize a process
D. to make an argument
Answer:
B.
Explanation:
Prior to the parasite lines, he mentions that epiphytes do not take nutrients from other plants, therefore, by capitalizing the word "do" he is creating emphasis on the contrast between his two statements about plants.

Why does energy transfer not always result in phase change?
PLZ HELP!!!
PLZ PLZ HELP!!!!
Answer:
These energy changes are mot changes into kinetic energy . They are changing in bonding energy between the molecules " If heat is coming into a substance during a phase change , then this energy is used to break the bonds between the molecules of the substance .
Explanation:
hope it helps !!
Energy transfer does not always result in phase change because ; Not all energy transfers breaks the bonds between molecules ( i.e. kinetic energy )
What is energy transferEnergy transfer is the movement/transfer of energy from one system to another usually in the form of heat , work or other form of mass transfer.
Not all Energy transfer results in the phase changes because some energy transfers are not Kinetic energies and do not breakup the bond between molecules.
Hence we can conclude that Energy transfer does not always result in phase change because ; Not all energy transfers breaks the bonds between molecules ( i.e. kinetic energy ).

Juanita is planning a scientific experiment to observe and record her community’s daily activities that release carbon dioxide into the atmosphere. She will use the data collected to construct a model. This will help make informed decisions on how best to reduce emissions and protect the environment. Which of the following activities would increase the amount of carbon dioxide in the atmosphere? Choose the three that apply.
A. plants conducting photosynthesis
B. eating a sandwich
C. a deer dies along the road
D. cutting down trees in a forest
E. driving a car to the store
Answer:
C, D, E
Explanation:
A: When plants photosynthesize, they actually use carbon dioxide in the process. Therefore, that would decrease the amount of carbon dioxide, so this choice is wrong.
B. Eating a sandwich has no effect on carbon dioxide levels.
C. If an animal dies, they are broken down by decomposers. During this process, any carbon in the animal's body is released into the atmosphere as carbon dioxide. This would increase the amount of carbon dioxide.
D. As stated before, plants photosynthesize. If we cut down trees, there will be fewer plants to take in carbon dioxide during photosynthesis. This will increase carbon dioxide levels.
E. When a car converts fuel into energy to move the car, carbon dioxide is released. Driving a car will increase carbon dioxide in the atmosphere.
C, D and E are correct.

A student drew this model to show the flow of convection currents
on Earth.
Part A
Is the model accurate? Explain your answer.
Answer:
Yes the model is correct
Explanation:
Transfer of heat energy takes place usually any of these three processes namely; Conduction, Convection and Radiation. In conduction, transfer of heat energy takes place by microscopic collisions of particles within a body. In radiation, heat, light and energy through any source is sent out from something and moves through space without a material medium of propagation. In Convection, heat transfer happens because of the movement of the bulk of molecules within fluids.
We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another.
The equator is the part on Earth that is nearest to the sun hence it receives much heat. As a result of this, the air near the equator rises upwards as it becomes less dense and later spreads out and again descends towards the equator. This process is responsible for the continual circulation of air which is called wind. It is due to the process of atmospheric convection currents that the clouds are kept aloft.
From the foregoing, the model shown in the image has been validated as a correct model of convection current in nature.
Answer:The model accurately shows convection. However, these large convection currents would occur only if Earth did not rotate. Because Earth rotates, smaller convection cells form.

Discuss, why is rubisco the key enzyme for the production of worlds food
Answer:
Rubisco is the major enzyme used to catalyse the carbon fixation step during the Calvin cycle in photosynthesis.
During carbon fixation, RUBP undergoes a redox reaction with CO2 to form 3-phosphoglycerate (a 3 carbon compound). 3-phosphoglycerate then undergoes phosphorylation by ATP and reduction by NADPH to form glycerate 3 phosphate molecules (main product), ADP and NADP+ molecules (by product).
Some Glycerate 3 phosphate produced are used to regenerate RUBP for the Calvin cycle to continue while the rest of the Glycerate 3 Phosphate is used to synthesise monosaccharides like glucose.
Without Rubisco, carbon fixation cannot occur and RUBP will not be able to combine with C02 to form a 6 carbon unstable intermediate the breaks down to form 3-phosphoglycerate and eventually undergoing more reactions to form glycerate 3 phosphate which is the basic product of photosynthesis used to synthesise glucose and eventually starch which serves as the world's food.
What is the carbon/oxygen cycle?
How does oxygen enters the atmosphere?
How does carbon dioxide enters the atmosphere?
What are 3 ways oxygen is released into the environment?
Answer:
Explanation:
*Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves.
*Plants use sunlight and carbon dioxide to produce oxygen through the process of photosynthesis.
*Carbon dioxide is added to the atmosphere naturally when organisms respire

In an atom why don’t the electrons float away ? The float around in the electron cloud but what keeps them from floating away ?
Answer: If an electron is in the electric field of a nucleus, the electron can occupy only certain energy levels. When it is sitting on one of these energy levels, it does not radiate, it does not loose energy.
Clouds are made of water droplets and ice crystals. A cloud's individual particles are so small, Also that warm air rising from the earth's surface is able to keep them floating in the air.
Electron clouds are the energy levels where the probability of getting an electron is maximum. These float due to the small size which results into rising them from the earth's surface.
What are the electron cloud?
An electron cloud can be defined as the region which is surrounding an atomic nucleus in the atom in which there is a high probability of an electron being located.
If an electron, negatively charged particle is in the electric field of a nucleus, then the electron can occupy only certain energy levels in the atom. When it is sitting on one of these certain energy levels, then it does not radiate, and hence does not loose energy.

Do shrimp follow the Carnegie stages of development?
Shrimp Eggs: The shrimp start as small almost invisible eggs and are food to zooplankton until they spawn due to becoming stimulated by temperature change and become larvae.
Nauplius Larva and Protozoea Larva: Larvae developed from fertilized eggs.
Mysis Larva: These are carried toward shore and continue to feed on zooplankton and phytoplankton.
Postlarva: These tend to be moved toward brackish waters and begin to look, forage, and graze like shrimp. They develop swimming and walking legs.
Juveniles: They can continue to interact with many species as predator and prey.
Subadult: Temperature changes stimulate growth and regulate its migration to sea.
Adult: Continues to grow on the sea bottom. Many are fed on by animals such as pinfish, silver sea trout, sharks, and redfish and snared by commercial trawlers.
