How are many unicelled organisms. In addition , anything less than a cell is not alive. What do these statements imply about cells?
Answer:
The correct answer is - cells are the basic unit of life.
Explanation:
As it is given and also known that there are many unicellular organisms exists and they do not require the multicellular body to live their life or survival. Multicellular organisms are made up of various cells joined together to form a complex organization.
Anything less than a cell can not live or survive and also do not called a living entity. So, from above we can say the basic unit of the life is cell.

When someone says the word "desert," what plant do you picture? You're probably
picturing the saguaro cactus. Saguaros are known for their long, tall branches that look like
arms. These branches don't start to grow until the cactus is 50 to 70 years old. The folds
along the saguaro's stem and branches are called pleats. What are they for? These pleats
store water for the cactus, which is important in the hot, dry desert. A desert plant's spikes
aren't just to keep animals away. They also help provide shade during the long hours they
spend in the sun.
A saguaro cactus will

water molecules are polar.

In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic? Which direction was water flowing?
Answer:
1. Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
2.
a. A semipermeable membrane allows some substances to pass through it.
b. The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
3.
a. The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
b. In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
4.
a. The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
b. In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
5.
a. A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
b. If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Explanation:
When protein molecules were evenly distributed on both sides of the membrane, the solution is isotonic.
In isotonic solution the concentration of solutes on side remain same .There is no net gain or less of water in isotonic solution.What will be the direction of water flow in isotonic solution?The water will flow freely across the cell membrane without any change in the concentration of solutes.In isotonic solution the cell neither shrink nor swell because the water concentration will remain same.To know more about isotonic solution here

Census data show that the human population doubled from 2.65 billion in 1953 to 5.3 billion in 1990. If it continues to double at this rate, the human population could reach 10 billion by the year 2020. Which best explains how this rate of human growth can harm the environment on which humans depend?
The question is incomplete, the complete question is;
Census data show that the human population
doubled from 2.65 billion in 1953 to 5.3 billion
in 1990. If it continues to double at this rate,
the human population could reach 10 billion
by the year 2020. Which BEST explains how
this rate of human growth can harm the
environment on which humans depend?
A. by gradually making up more available energy
B. by using resources faster than they can be
replaced
C. by changing how matter cycles through an
ecosystem
D. by increasing the variety of ecosystems that are
Answer:
by using resources faster than they can be
replaced
Explanation:
As population of the world continues to grow, there is greater demands for resources which are obtained from the environment such as crude oil for energy, solid minerals for various applications, wood for furniture etc.
Demand for these materials increase exponentially as population increases thus they are extracted at a faster rate than nature can replace them. This will eventually harm the environment on which humans depend as population increases.

Discuss the benefits and drawbacks of
using solar energy and wind energy.
Answer:
hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"
Answer:
Solar Energy:-Benefits-
Solar power is completely cleanIt produces no air pollution, no water pollution, no greenhouse gas effects and carbon - free alsoNo harmful emissions are released when electricity is being produced by solar panels.It also reduces the need for finite resources.Drawbacks-
Solar Energy Storage Is ExpensiveUses a Lot of SpaceIts Weather-Dependent, slthough solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.Initial cost of purchasing a solar system is fairly high.Wind Energy:-Benefits-
Wind is a domestic source of energyIt's a clean fuel sourceIt's sustainable and causes no harmful emissions. Wind energy is a green energy source and does not cause pollution.Drawbacks-
Wind turbines are prone to noise disturbances.The wind is inconsistentWind turbines involve high upfront capital investment.Installation can take up a significant portion of land.The variable h represents the number of hours spent doing yard work and the variable d represents the amount of money earned how many hours spent doing yard work and the variable d represents the amount of money earned how many hours in all will it take Whitney to earn 15$
Answer:
[tex]4\frac{1}{11}[/tex] hours
Explanation:
Given
See attachment for graph
First, we determine the equation of the graph.
Pick any two points from the graph
[tex](h_1,d_1) =(18,168)[/tex]
[tex](h_2,d_2) =(36,366)[/tex]
Calculate the slope (m)
[tex]m = \frac{d_2 - d_1}{h_2 -h_1}[/tex]
This gives:
[tex]m = \frac{366 - 168}{36 -18}[/tex]
[tex]m = \frac{198}{18}[/tex]
[tex]m = 11[/tex]
The equation is then calculated as:
[tex]d = m(h - h_1) + d_1[/tex]
This gives:
[tex]d = 11(h - 18) + 168[/tex]
Open bracket
[tex]d = 11h - 198 + 168[/tex]
[tex]d = 11h-30[/tex]
So, the number of hours to earn $15 is:
[tex]d = 11h-30[/tex]
[tex]15 = 11h -30[/tex]
Collect like terms
[tex]11h = 15 + 30[/tex]
[tex]11h = 45[/tex]
Solve for h
[tex]h = \frac{45}{11}[/tex]
[tex]h = 4\frac{1}{11}[/tex]

4. The human population has experienced unchecked growth for the past 200 years. What does "unchecked" mean? A. Slow b. At a steady rate c. Unrestrained d. Dangerous
Answer:
B
Explanation:
The correct option would be B
The human population experiencing unchecked growth for the past 200 years does not mean that there were no restraining factors that limit the population. Factors such as death, competition for resources, diseases, etc., were still present.
Despite the limiting factors, the population has been growing. Hence, the correct word to replace 'unchecked growth' would be 'at a steady rate'.
Slow and dangerous really have nothing synonymous with unchecked growth.
The correct option is, therefore, B.
