Jenna's age Jessica's age

today x x + 5


in 5 years x+5

5 years ago x + 5 - 5


Equality x + 5 = x + 5 - 5

=> x + 5 = x


The equation is x + 5 = x


That equation has not any solution, because it reduces to 5 = 0, which is an absurd.


So, the conclusion is that information given by Jenna is wrong.


It is logical: if the difference of the ages is 5, in five years Jenna will have 10 years more than what her sister had 5 years ago, no 5 as she told Jessica.

What changes during a controlled experiment? A. A variable B. The results C. The conclusion D. The hypothesis

Answers

Answer:

Option B

Explanation:

The answer is option B or "the results." Wouldn't be option A because a variable depending on the type is tested during a experiment if you change the variable you have a whole other experiment going on, it wouldn't be option D because your hypothesis is a logically guess at the beginning of a experiment of what you think is going to happen and it doesn't change. It wouldn't be option C because the conclusion is at the end of the experiment after you finished testing, recorded the results, and found out if your hypothesis is correct meaning it doesn't change, leaving option B as your answer.

Hope this helps.

How does osmosis of water occur across the cell membrane?Plz help I need it ASAP

Answers

Answer:

In osmosis, molecules cross the cell's plasma membrane to achieve equilibrium.

Explanation:

A bilipid layer called a plasma membrane typically surrounds cells. Here, lipid molecules are arranged tail-to-tail, with their heads facing outwards. The heads of the lipids, are water soluble, while the tails are insoluble. Proteins and cholesterol also help maintain membrane fluidity.

With the use of its transport proteins, pores and gated channels, embedded among the lipids the membrane maintains its concentration of substances through selective permeability.

Simple diffusion occurs in cells through plasma membranes as a means of passive transport. In osmosis, molecules of water move across the membrane, down their concentration gradient- i.e. they try to balance their concentration or number of water particles.

The water particles move from regions of high concentration to regions of low water concentration. Typically these 'destinations' or regions have large amounts of solute which contributes to the formation of this gradient.

Which kind of root system would more likely benefit a desert plant----a taproot or a fibrous root system? Why?

Answers

Answer: The taproot

Explanation: A deep taproot helps plants use moisture held in deeper soil layers, and they can have great drought resistance compared to fibrous-rooted plants. An example is honey mesquite (Prosopis juliflora), which is known to send its roots down 150 feet to get water.

A city wants to reduce groundwater overuse. Which of the following suggestions should the city council make to the community?
A)Create educational fliers about how to properly dispose of toxic cleaning products.
B)Look into drilling personal wells on their own property.
C)Increase the number of public trash cans to avoid littering.
D)Reduce the frequency of lawn watering during rainy seasons.

Answers

Reducing the frequency of lawn watering during rainy seasons will help

reduce groundwater overuse.

Groundwater is found deep below the soil as a result of them seeping into

the ground during rainfall. Some of them are emptied into water bodies such

as seas, oceans etc. Water pumping machines forces the water out for

by individuals.

The use of the groundwater will however be reduced by a reduction in the

frequency of lawn watering during rainy seasons.

Describe what changes were made to historical cell theory and explain why these changes were
made.

Answers

Three scientists are credited with the development of cell theory. Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name.

Compare temperature and pressure conditions on the Earth's surface to those below the Earth's surface, and relate these conditions to the process of lithification.

Answers

Answer:

Explanation:

The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.
