Answer:

The best answer from the list of options is option D (They are colorless and feed on other, smaller cells)

Explanation:

Euglenas have cells that contain chloroplasts, which means they can make their food like plants through photosynthesis, and when it is dark where they can't get sunlight they can also make food by engulfing their prey through the plasma membrane and absorb them. Euglenas are heterotrophic since they call also feed on smaller cells. Their whip-like tail when viewed under the microscope, is colorless. However, the chloroplasts make them appear green and they can also come in red color.

In general, the land changes temperature much more rapidly than the ocean. How does this fact explain the existence of land bree
Greeley [361]

<u>Answer:</u>

<em>Land and sea breeze are produced because the land changes temperature rapidly than the ocean. </em>

<u>Explanation:</u>

<em>The rates of heating up of land and sea are different. Land gets heated up faster than water. Temperature is crucial in determining the density of air. </em>

When land gets heated up the air near the land turns hot and this temperature is greater than the temperature of the air near the water surface. <em>Hotter air has less density than the air which is relatively less warm. Density difference creates pressure difference. </em>

Denser air has higher pressure than less dense air making air move from area of high pressure to area of low pressure. During the day<em> the land is heated up more and thus air move from sea to land and it is called sea breeze. </em>Just like it absorbs heat land releases heat at a faster rate.  

<em>Thus at night land the sea will be warmer than the sea and thus air will move from the land to the sea and it is called land breeze. </em>

What type of stellar object will the sun end its life end
Lerok [7]
Your wording is a bit confusing, but I get what you're trying to say.

Here's what the life cycle of a star looks like.

Stars begin as giant balls of hydrogen colliding together and releasing a ton of energy. This hydrogen will eventually fuse together to form helium, and once all of the hydrogen has become helium, This helium will, after a very long time and under lots and lots of pressure, form carbon. When this happens, it is considered a red giant, and the star becomes bigger and less bright. The star will become less and less bright and eventually start to shrink as all of that carbon turns to heavier elements like iron, turning into a dwarf star that eventually dies out.
(Dwarf stars are still shining are called white dwarf stars, and dead ones are black)

The cool part, though, is that massive stars (those which have a mass of at least 3 times the Sun's) turn into heavy elements so fast that the core collapses almost instantaneously and explodes violently into a ball of fire known as a supernova.

Sometimes the core of the star gets left behind, and either forms a neutron star or, if it has the mass of a massive star, will collapse in on itself and become a black hole.
