The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environement. What condtions cause the contracile vacuole to fill with water? Your answer: The concentration of water is greater outside the cell than inside the cell. The concentration of water inside the cell is the same as the concentration outside the cell. The temperature of water in the vacuole is higher than the temperature of its environment.

The Picture Shows A Contractile Vacuole Of A Unicellular Freshwater Organism. The Contractile Vacuole

Answers

Answer 1

Answer:

The concentration of water is greater outside the cell than inside the cell.

Explanation:

In living cells, water moves by Osmosis across the cell membrane, which acts as the semi-permeable membrane. Osmosis is the movement of water molecules from a region of high water concentration (low solute concentration) to a region of low water concentration (high solute concentration).

The contractile vacuole of this freshwater organism helps regulate water intake and exit by storing excess water. According to osmotic flow, water will flow into the organism via its cell membrane (semi-permeable membrane) because the concentration of water outside the cell is high than inside the cell, hence, this causes an osmotic gradient causing water to flow into the cell. The water that flows into the cell is stored in the Contractile vacuole.

Which evidence has led scientists to conclude that there are different layers within Earth's interior?
(1) analysis of earthquake wave data
(3) rock samples taken from Earth's core
(2) measurement of Earth's diameter
(4) temperatures taken within each layer

Answers

Answer:

Explanation:

1) análisis de datos de ondas sísmicas

Evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.

What is the significance of the different layers within Earth?

There are various layers on the earth with distinct significance, such as the crust and the upper part of the mantle, which make up the lithosphere, which is the solid part of the Earth, and the tectonic plates that are constantly moving and colliding, which causes earthquakes and volcanic activity. The core is the inner part that has the magnetic fields, and the mantle is the part present in between the crust and the core.

Hence, evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.

When the moon casts its shadow on Earth, a lunar eclipse occurs.

The last option is correct.

How do we explain?

A lunar eclipse happens when the Earth's shadow falls on the moon. This can only happen during a full moon, when the sun, Earth, and moon are perfectly aligned.

The Earth's shadow has two parts: the umbra and the penumbra. The umbra is the darkest part of the shadow, and it is where the moon will completely disappear. The penumbra is the lighter part of the shadow, and it is where the moon will only partially disappear.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the choices provided A B C D

Answers

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

Answer:

a.14.59

One of the Indians that came from Medfield fight, had brought some plunder, came to me, and asked me, if I would have a Bible, he had got one in his basket. I was glad of it, and asked him, whether he thought the Indians would let me read? He answered, yes. So I took the Bible, and in that melancholy time, it came into my mind to read first the 28th chapter of Deuteronomy, which I did, and when I had read it, my dark heart wrought on this manner: that there was no mercy for me, that the blessings were gone, and the curses come in their room, and that I had lost my opportunity. But the Lord helped me still to go on reading till I came to Chap. 30, the seven first verses, where I found, there was mercy promised again, if we would return to Him by repentance; and though we were scattered from one end of the earth to the other, yet the Lord would gather us together, and turn all those curses upon our enemies.
