Answer:
The formula for calculating magnification is:
Magnification = Size of drawing / Actual size
Size of drawing = 40 mm
Actual size = 40 micron meter
Convert 40 mm to micron unit: 40 * 1000 = 40,000 micron
Magnification = 40,000 / 40 = 1000.
The magnification is 1000 X.
This answer means that the drawing is 1000 times bigger than the actual size of the cell.

What is the most important renewable resource ( In your opinion) and why? What is the most important non-renewable resource (again, in your opinion) and why? Please don't copy and paste.
Answer:
Renewable: Solar Power
Non-Renewable: Fossil Fuels
Explanation:
I think the most important renewable resource is solar power because it is useable in many areas easily.
I think the most important non-renewable resource is fossil fuels because they can be mass exported and they are cheap.

Experiments on Osmosis are often carried out using potato
cylinders. You have been asked to find out if sweet potato or bread
fruit would be a good alternative
The osmosis process is based on solute concentration, if sweet potato or breadfruit has more amount of sucrose changing the osmolarity, hence not used for osmosis.
What is osmosis?When a potato is placed in salt water, all the water inside it, plants have a lot of water inside them, that's what gives a plant its structure travels out by osmosis because water will move from an area of less salt to more salt (more water to less water).
The cells that makeup potatoes have cell walls that function as semipermeable membranes. In comparison to the fluid inside the potato cells, the saltwater solution is hypotonic, meaning that it has more water and fewer salts.
This is because a sweet potato has more sugar than a regular potato, changing the osmolarity conditions during osmosis.
Therefore osmolarity condition is more important during osmosis, hence sweet potato or breadfruit would not be a good alternative.

A student hypothesized that bread mold would grow faster in a dark environment than a well-lit environment. She took four slices of bread from the same loaf, sprayed each with the same amount of water, and sealed them inside plastic bags. She kept two slices on the kitchen counter for six days. She kept the other two slices in a cardboard box inside her pantry for six days. She measured mold growth every two days. The table shows her data.
Based on the results of the experiment, how should the hypothesis be refined?
A. Bread mold cannot grow in a dark environment.
B. The rate of bread mold growth increases with exposure to light.
C. A wooden box will provide more darkness than a cardboard box.
D. The more moisture a slice of bread receives, the more mold it will support.
Answer:
it is:High moisture and low temperature encourage mold to grow.

Answer:
The correct answer is:
planters (D)
Explanation:
The key statement in the question is that Andrew wants to apply pesticides and fertilizers to all his crops across his large land. The most effective way of doing this is by using a planter to apply both the fertilizer and the pesticide as the planting occurs. This will ensure that the fertilizers and pesticides are applied directly to the crops and not scattered on the vast land.
What are three ways a plant's organ systems work together?
A The shoot system delivers food to the root system.
B. The root system delivers materials from the soil to the shoot
system
The ground tissue of the root system protects the vascular tissue
in roots
D. The ground tissue of the root system stores food for later use by
leaves
Answer: A, B, D
Explanation: credit to the comments on the other. I also did the test
The three ways through which a plant's organ systems work together are as follows:
The shoot system delivers food to the root system.The root system delivers materials from the soil to the shoot system. The ground tissue of the root system stores food for later use by leaves.Thus, the correct options are A, B, and D.
How do plants deliver water and nutrients to other parts?Plants deliver water and other nutrients to other parts with the help of vascular tissues like xylem and phloem.
Xylem transports water, nutrients, and other minerals from the soil to all parts.
Phloem mediates the migration of foods from the leaves to the rest of the plants.
The shoot system delivers food to the root system via the vascular tissue phloem. The root system delivers materials from the soil to the shoot system via the vascular tissue Xylem.
The ground tissue of the vascular plant is responsible for storing the carbohydrates constructed by the plants and utilized by the leaves when required.
Therefore, the correct options are A, B, and D.

Controlled scientific experiments include variables. One kind of variable is an independent variable (test variable) and the other kind is a dependent variable (outcome variable.) Which statement best describes the difference between these variables?
A.
The dependent variable does not change and the independent variable does change.
B.
The dependent variable does not change and the independent variable does not change.
C.
The dependent variable is the control and the independent variable is the result.
D.
The dependent variable changes due to the changes made to the independent variable.
The dependent variable changes due to the changes made to the independent variable is the statement that best describes the difference between these variables. So, the correct option is D.
What do you mean by Variables?Variables may be defined as those components whose values may be changed during the course of the experiments.
The variations in the dependent variable rely on the value of independent variables. According to the independent variable, the values of dependent variables are met.
Therefore, the dependent variable changes due to the changes made to the independent variable is the statement that best describes the difference between these variables. So, the correct option is D.

The Galapagos island has a variety of tortoises with different physical characteristics. Can a Domed tortoise survive that lives on Isabella survive on the Island of Espanola? Explain.
Explanation:
Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks.
Answer:
Probably not. This is because the islands at Galapagos islands are all diverse and the turtles that live on each island have characteristics that help them survive on their island and not any other island so if you were to move one of the turtles locations it probably wouldn't survive because it doesnt have the needed characteristics do survive.
