What is the source of most salt in the ocean?
A.fish
B.human activity
C. Wind
D. Rocks on land

Answers

Answer:

D. rocks on land

Explanation:

Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

Answer:

Option D Rocks on land

You will build a simulation of a population using the same elements as the simulation pictured here and show how
the traits in this population change in years 5 and 10.
- Trait A
- Trait B
- Trait
1 circle = 50 organisms
Start off with 2,500 plants of which 50% have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip
leaves. Each circle in your simulation will represent 125 organisms. Calculate how many circles you need for each
trait, and then create your simulation. Be sure to include a key that states the color coding for each trait.

Answers

According to the concepts of percentage and proportions, we can make the simulation with 20 circles, each of them representing 125 plants. Traits A = 10 circles. Trait B = 5 circles. Trait C = 5 circles.

To solve this problem, we need to know two concepts, percentage and proportion.

What is a percentage?

A percentage can be defined as a fraction or a part of 100. It is denominated as percent (symbol %).

100 refers to the number of parts into which the unit has been divided.

So, X% means that for every 100 parts, X parts are of our interest. Or, that  we are interested in X fraction from a total of 100 parts.

What is a proportion?

A proportion is the equal relationship between two determined ratios or quantities.

In the exposed example we need to represent this population of 2500 plants with circles.

We know that,

Each circle represents 125 plants50% of the population have medium-tip leaves, 25% have wide-tip leaves, and 25% have drip-tip leaves .

So here, our unit is the population. We can say that our population of 2500 plants is composed by 100 subunits or parts.

2500 plants ------------ 100 parts

So now we will calculate how many plants are represented by the 50% and 25% of the population.

If 100% of the population equals 2500 plants, how many plants are 50% of the population and 25% of the population.

100% -------------------- 2500 plants

50% -------------------- X = (50% x 2500 plants) / 100% = 1250 plants.

25% ---------------------X = (25% x 2500 plants) / 100% = 625 plants

Now we know that from the total of 2500 (100%) plants,

1250 (50%) have medium-tip leaves, 625 (25%) have wide-tip leaves, and 625 (25%) have drip-tip leaves.

Finally, we need to calculate how many circles represent these numbers. So, we know that 1 circle equals 125 plants. The question is, how many circles represent 2500, 1250 and 625 plants.

125 plants ----------------- 1 circle

2500 plants -------------X = (1 circle x 2500 plants) / 125 plants= 20 circles.

1250 plants --------------X = (1 circle x 1250 plants) / 125 plants = 10 circles.

625 plants ---------------X = (1 circle x 625 plants) / 125 plants = 5 circles.

So, our simulation must have 20 circles, from which

10 circles represent medium-tip leaved plants (Trait A), 5 circles represent  wide-tip leaved plants (Trait B), and the remaining 5 circles represent drip-tip leaved plants (Trait C).

In the attached files you will find the image.

how does the surface area to volume ratio affect the rate of diffusion​

Answers

Explanation:

As the ratio gets smaller, it takes longer for items to diffuse.

Explanation:

When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.

When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.

this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.
