Please help now I need it. You need to develop a demonstration to show evidence of how cellular respiration and photosynthesis depend on each other. Your presentation will show how cellular respiration is the process by which all cells transform food into energy, whereas photosynthesis is the process by which plants obtain food. Your experimental design should show evidence of how cellular respiration and photosynthesis depend on each other.

Answers

I may not be able to make you a presentation, but I can help you on the idea behind it. Photosynthesis is 6 Carbon dioxide 6 water and light to make glucose and oxygen. With cellular respiration, its the opposite. Glucose + oxygen to break it down and forms waste products of 6 carbon dioxide and 6 water. The main thing it produces though is ATP (Adenosine Triphosphate). ATP is the product of cellular respiration and is fuel for your cells to function. I hope this helps. There are different stages in photosynthesis and cellular respiration that I’m not going to dive into, but this is the main reason why they depend on each other. Because unlike humans where we eat food, they use photosynthesis to make their glucose which they turn into ATP energy. Think I covered most of it. Good luck on your presentation!

A.about 35

B.about 10

C.about 5

D.about 25

Answers

Answer:

A

Explanation:

In the graph below, the maximum number of rabbits that can live and survive in the ecosystem is the 35 that are present in Option A, as it is the highest carrying capacity of the ecosystem.

What is the influence of carrying capacity on rabbits?

carrying capacity of the ecosystem depends upon many factors such as space, food availability, suitability, etc., and as per that, the carrying capacity differs. The graph here is plotted between the rabbit and the years, so the ecosystem can only support up to 35 rabbits, and any more would result in rabbit decline due to fewer foods and unsuitability of the environment.

Hence, in the graph below, the maximum number of rabbits that can live and survive in the ecosystem is the 35 that are present in Option A, as it is the highest carrying capacity of the ecosystem.

first answer (melted rock in the interior of the earth cools after so many years, turns to solid rock. after plates into each other, mountains form due to pressure which brings the rock on the earth's surface. another way is when rocks flow out with lava, the lava cools and hardens into a rock). this is my first answer. Answer about how you think melted rock deep within Earth could change over time. Would you revise your answer now? If so, how? If not, explain why.

Answers


The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes

Melted rock within the Earth changes over time crystallization and forms igneous rocks.

What is an igneous rock?

One of the three primary rock types, along with sedimentary and metamorphic rocks, is an igneous rock, also known as magmatic rock. When lava or magma cools and solidifies, igneous rock is created. The partial melting of pre-existing materials in the mantle or crust of a planet can produce the magma.

Based on their chemical makeup, igneous rocks can be categorised into four groups: felsic, intermediate, mafic, and ultramafic. Most of the crust of the earth is made up of igneous rock.

The most typical igneous plutonic rock is granite. contains essential quartz, plagioclase, and alkali feldspar; hornblende, biotite, and/or muscovite are frequently present.

Describe the movement of Earth’s mantle. Explain how convection currents can cause tectonic plates to move.

Answers

Answer:

Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart. Where convection currents converge, plates move towards each other.

Convection currents from core radioactive decay rise and fall in the mantle. Convection currents move plates. Plates separate near convection currents. Plates converge at convection currents.

What are convection currents?

Convection currents are caused by differential heating. Warm, less dense, lighter material rises while cool, more dense, heavier material sinks. Convection currents are patterns of circulation that are produced by this movement in the Earth's mantle, oceans, and atmosphere.

Convection currents are produced by radioactive decay in the core and are caused by heat rising and falling inside the mantle. The plates are moved by convection currents. Plates separate where convection currents split close to the Earth's crust. Plates move in the direction of one another where convection currents converge.
