Answer:

The correct answer will be- the bark of an oak tree by Antonie Van Leeuwenhoek

Explanation:

The development of light microscopy began before the 18th century where a scientist named Antonie Van Leeuwenhoek observed the first living cells of the organisms.

Although the first cell was observed by the Robert Hooke when he observed the dead cells of the bark of a tree bu the light microscope designed by the Leeuwenhoek helped him to observe the living cells from the pond life and he also observed the bark of an oak tree.

Thus, the bark of an oak tree by Antonie Van Leeuwenhoek is considered the first cell.

Some people use paint to protect the outside of their houses. Why does a house painted a dark color get hotter than a house pain
Trava [24]

Answer:

Dark color absorb more photons and thus gets more hot

Explanation:

Dark color is dark b/c it absorbs different wavelengths of light (think about little photons of light vibrating slighting differently) .This means it absorbs a lot of photons which makes it warmer.

If a thing is white, that means it reflects all lights and absorbs none. Thus, since it does not absorb photons (little packets of energy which is light), the house does not get warm.

Which of the statements about half-life are true?
Oksana_A [137]

The statements which are true about half-life are given below:

  • A radioactive element's half-life stays the same when its temperature changes.
  • A radioactive element's half-life stays the same when the pressure upon it changes.

Thus, the correct options are B and F.

<h3>What is Half-life?</h3>

The half-life of any radioactive element may be defined as the time taken for the radioactivity of a specified isotope to drop to half of its original value.

The above statement is true about the half-life of any radioactive element because the half-life of any substance does not depend on pressure, temperature, and concentration.

Therefore, it is well described above.
