Since oceans cover 71% of the Earth’s surface, understanding what the seafloor looks like, and where different processes, such as ocean currents are active, is hugely important. Mapping the seafloor helps to work out things like where different types of fish live, where resources may be, such as rare metals and fossil fuels, and whether there is a risk of underwater landslides happening that might cause a tsunami. Mapping the seafloor is very challenging, because some cannot use the same techniques that some would use on land. To map the deep ocean, there's a tool used called a multibeam echo-sounder, which is attached to a ship or a submarine vessel.

Anaerobes carry on whereas aerobes carry on cellular respiration
Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
Aerobic Respiration
Occurs in the presence of free oxygen.Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules. Respiration occurs in the mitochondria.Takes place in two steps or stages: Krebs cycle and electron transporter chain. Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.Anaerobic Respiration
Occurs in the absence of free oxygenSeries of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced. There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation. Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂The whole anaerobic process occurs outside the mitochondria.In a meeting, the presiding officers would like to convince the group on the

4. Compare and Contrast Which kind of plant–a sun plant or a shade plant-has a
higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?
Answer:
Below 200 umol photons/mº/s, shade plant grow best.
Above 400 umol photons/mº/s, sun plant grow best.
Explanation:
A shade plant has a higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.

what happens when a person is infected with live pathogens
Answer:Once you're infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.
Explanation:
Answer:
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.

Can someone explain the Punnett square ?
Answer:
so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB. next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.
Explanation:
the main points.
in this example, i used B to be the dominant gene and b to be the repressed/ submissive gene. you always put the dominant gene letter before the repressedmake sure you fill the squares in properly. in this one, you should have 3 BB and 1 Bb. this shows that the gene set BB is going to showwhen you fill in the squares, the first top letter and the first side letter fill in the top left square.the first top letter and the second side letter go left bottom.second top letter and first side letter go in right top.second top and second side go in right bottom.always place the dominant gene first in the punnet square.add me and message me if you need more help. we can also zoom to figure it out.
A _______________ from the sun hits chlorophyll and excites an electron, known as __________________________________.
Answer:
Photon, light dependent reaction of photosynthesis
Explanation:
Photosynthesis is the process by which green plants make their own food in the presence of sunlight and water.
There are two steps of Photosynthesis that include light dependent reaction and light-independent reaction.
In light dependent reaction, a photon from the sun is absorbed by the green pigment in leaves called chlorophyll that allow the electron to excite from ground energy level to high energy level. It converts the solar energy into chemical energy and called light dependent reaction of photosynthesis.
Hence, the correct answer is "Photon, light dependent reaction of photosynthesis".
Which of the following processes cycles matter through different parts of an ecosystem?
More than one answer may be correct.
1. the nitrogen cycle
2. the water cycle
3. the carbon cycle
Answer:
the nitrogen cycle, the water cycle, and the carbon cycle
Explanation:
The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.
The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.
What is a biogeochemical cycle?The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.
These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.
Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

Part 2: Which type of energy transformation is taking place at this location?
Part 3: Justify why this process is a recycling of carbon in the carbon cycle.
Use complete sentences to explain your answer.
Answer:
This is too difficult to read and understand... if you had a diagram I could be able to help more, but I can't figure out exactly what your asking... all I know is part A is CO2 being released into the atmosphere...
Hope you have a great day and if you have a diagram let me know.. I'd love to help :D
Answer:
Part I
At location G, the process of combustion is taking place where hydrocarbon or organic carbon from the fossil fuel is burnt in the presence of oxygen to produce carbon dioxide and water as the products.
CxHy = CO₂ + H₂O
Part II
At point G there is no transformation of energy since during the process of combustion energy will still be stored in form of chemical energy in the bonds of carbon Iv oxide and the water produced during the reaction.
Part III
The process shows recycling of carbon in the carbon cycle. This is because carbon from living organisms is cycled to non living organisms. When plants and animals die and are buried deep in the ground, they are then slowly converted to fossil fuels which contain organic hydrocarbon compounds including petrol, kerosene and other compounds. Then the fossils are used in the industries and undergoes combustion releasing carbon iv oxide which is then released to the atmosphere and used by the plants and animals. The process starts once again.

Explain how a mutation has caused the Lactase Persistence gene in some people and not in others.
Answer:
It is a case of human niche construction
Explanation:
Lactase is an enzyme of mammals which is required to digest lactose. In humans (like in other mammals), lactase activity decreases during mid-childhood; although there are individuals which are still capable of producing this enzyme even during adult life, a trait known as 'lactase persistence'. Different mutations in the coding region of the lactase gene have been associated with lactase persistence in European, African and Asian populations. On the other hand, the niche construction theory states that the organisms, through their activities and choices, actively modify their own local environment by introducing novel selection pressures. Some examples of niche construction include, among others, alternation of nutrient cycling by plants or lactase persistence in humans. Lactase persistence can be defined as a case of niche construction because this trait was not only genetically inherited but also culturally transmitted through local environments shaped by ancestral populations, i.e., generated by niche construction or ecological inheritance.
