What does the author predict about the future of the Earth's mantle? Do you support his educated guess? Use complete sentences to answer.
Because this region is immune to human meddling, the earth's mantle won't change in the future.
What transpires in the mantle of the Earth?We can determine the Earth's topography thanks to the heat and material transport taking place in the mantle. Plate tectonics is shifted by mantle activity, which also causes earthquakes, volcanoes, seafloor spreading, and the formation of mountains.
Therefore, since this area is protected from human interference, we can draw the conclusion that the earth's mantle won't alter in the future.

The temperature in the environment.
The temperature in the environment.
The water quality in the environment.
The water quality in the environment.
The air quality in the environment.
The air quality in the environment.
All of the above can affect photosynthesis.
Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.
The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.
For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.
The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell.
Based on this information, what type of transport is used for glucose in blood and intestinal cells?
A.
Both blood and intestinal cells take in glucose by passive transport.
B.
Blood cells take in glucose by active transport and intestinal cells take in glucose by passive transport.
C.
Blood cells take in glucose by passive transport and intestinal cells take in glucose by active transport.
D.

When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled.

Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.
1°C increase of temperature can effect the biodiversity of the habitat in terms of number of populations and number of individuals in the population, it can either increase or decrease the population growth.
1°C increase in temperature on biodiversity can increase or decrease the population growth.
Population growth or change in number of individuals in the population of some organisms increases or decreases with the increase in temperature. The population of certain species such as Nassuar grouperand, Queen angelfish increases with the increase in temperature while some species such as sponges and algae decreased in population with the increases in temperature. This is because some species need high temperature to grow, so even a 1°C increase in temperature increases the population while some species need low temperature to grow, so high temperature kills them and population is decreased.
