What is photosystem 1 and photosystem 2 and what do they do? What are the steps ?
P I and PII are proteic compounds present in the thylakoid membrane that contain about 300 chlorophyll molecules each.
Step IFirst of all light with a wavelength of 690nm is absorbed by P II. The light excites an electron that leads to the photolysis of water(H2O--->2H+ +2e- + 1/2O2). The two electrons released go into the electron transport chain. The second compound in electron transport chain is plastoquinone that is reduced when it accepts electrons then oxidised when it loses them to P I. The next two compounds are cytocromes that make hydrogen protons go inside the thylakoid when they recieve the electrons.(I will mention what happens to the H+ in the second step). The next compound in the electron transport chain is a compound that contains Fe and S. The electrons finally reach the last step: Reduction of NADP+ to NADPH+H+.
Step IIIn the second step is ATP synthesis. Hydrogen protons accumulate inside the thylakoid membrane. An electrochemical gradient is formed. The protons can leave the thylakoid according to this gradient through an enzyme.
When the protons flow through , it turns ADP into ATP.
To sumarize: the role of P II is O2 production through photolysis and ATP synthesis(indirectly) The role of P I is NADPH+H+ synthesis.

Read Changes on Earth and Changes in Life. Explain how changes in Earth’s systems affect the growth of life on Earth. Use evidence from the text to support your answer.
Any changes on earth has a big effect on life in general like for instance rock reformation volcanoes eruption and global warming has made a huge impact on our environment as earthquake or volcanoes occur it has changes the formation of our earth causing ocean water to reach high tides that can even cause tsunami's that cause a lot of trouble in rare cases due to the intensity of the movement A another example is Australia wild fires in this phenomenon caused a lot of people to evacuate their home and animals losing their habitat and making our air quality worse and it affects a lot more people aspects in life and people in so many ways like now there home where burned down they might be homeless and that is my explaining on how earth systems affects the growth in our life, earth.
Which of the following is NOT true of Chlorophyll?
A) It reflects all the colors of light but absorbs the green.
B) It reflects the green wavelengths of light and absorbs all the rest.
C) It is essential for photosynthesis?
Answer: A.It reflects all the colors of light but absorbs the green.
Explanation:
Photosynthesis, which gives plants their green hue, requires chlorophyll. Therefore, option (A) is not true.
What is chlorophyll?Chlorophyll, the pigment that gives plants their distinctive green hue, is crucial to the process of photosynthesis, which provides energy for a plant's metabolism, growth, and reproduction. Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green hue. The plant appears green because it reflects that particular light wavelength. Autotrophs are plants that produce their own sustenance through photosynthesis.
The stroma, which is the area between the thylakoid and chloroplast membranes, is where the chlorophyll, the green pigment, is found.

This table shows how the levels of classification have changed with each major scientist.
Which number belongs in the space labeled X?
A. 5
B. 7
C. 8
D. 10
Answer:
Woese increased the number of levels of Hierarchy from 7 to 10, therefore the answer is D. 10
Explanation:
Carl Woese classified the three domains of life so 10 belongs in the space labelled X.
Who was Carl Woese?Carl Richard Woese was a microbiologist and biophysicist from the United States.
Woese is best known for identifying the Archaea (a new category of life) in 1977 through the phylogenetic taxonomy of 16S ribosomal RNA, a technique he pioneered and which revolutionized microbiology.
In 1967, he also proposed the RNA world idea, though not under that name.
Woese was a professor of microbiology at the University of Illinois in Urbana–Champaign and held the Stanley O. Ikenberry Chair.
Woese classified the various living forms into three categories:
Eubacteria, Archaebacteria, and Eukaryotes.
The three-domain classification is also useful for determining the evolutionary relationships between organisms.
Hence, the correct answer is D i.e. 10

Which parts of the water cycle the water molecules to give away heat energy?
Answer:
evaporation i think but im not sure
Explanation:
Answer:
condensation
Explanation:
Precipitation, runoff, infiltration, and ground water. Is the source of energy that drives earths water cycle. The sun. As heat energy was added to the water, it changed states from. A liquid to a gas. This gas is called water vapor. As more energy is added to the water, the water molecules move.
The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. Would the use of created wetlands be considered biotechnology
Answer:
Yes; the use of created wetlands would be considered biotechnology.
Explanation:
The created wetlands will employ the use of scientific tools and techniques, which will largely modify the plants, animals, and microorganisms in the Gulf of Mexico's dead zone. Generally, it has been established that biotechnology allows farmers to grow more food with environmentally sustainable farming techniques, which also improve soil conservation.
Answer:
Yes, the use of created wetlands would be considered biotechnology.
Explanation:
Biotechnology uses biological systems and living organisms to develop and create different products. The new wetland that they create will be made with the usage of scientific tools and techniques in order to replicate an already existing biological system. It will have very modified plants, animals and other organisms in the Gulf of Mexico's dead zone.

A. Stationary
B. Warm
C. Occluded
D. Cold
When a cold air mass replaces a warm air mass, it's called a Cold front (Option D).
What is a Cold front?A cold front is a limit between two masses of air (one mass that is cool and the other that is warm).
This cold front may be very unstable and thus may be associated with the presence of storms.
In mid-higher latitudes, cold fronts generally advance the Equator by pushing the warm air up.
In conclusion, when a cold air mass replaces a warm air mass, it's called a Cold front (Option D).
