The fetus relies upon its mother as it develops. These are some of the things it needs:
<span>protection against knock and bumps, and temperature changes
oxygen for respiration
nutrients (food and water)
</span>
The developing fetus also needs its waste substances removing.
The fetus is protected by the uterus and the amniotic fluid, a liquid contained in a bag called the amnion.
Proton is the answer ur looking for. have a wonderful day :) !!
Answer:
<em>The comoving distance and the proper distance scale</em>
<em></em>
Explanation:
The comoving distance scale removes the effects of the expansion of the universe, which leaves us with a distance that does not change in time due to the expansion of space (since space is constantly expanding). The comoving distance and proper distance are defined to be equal at the present time; therefore, the ratio of proper distance to comoving distance now is 1. The scale factor is sometimes not equal to 1. The distance between masses in the universe may change due to other, local factors like the motion of a galaxy within a cluster. Finally, we note that the expansion of the Universe results in the proper distance changing, but the comoving distance is unchanged by an expanding universe.
It is called the specific latent heat of fusion. C.
This is the heat change required in changing 1kg of a solid to its liquid and it occurs at the melting point. It is not associated with temperature change.
If it is to convert 1kg of liquid to vapor at its boiling point it is called the latent heat of vaporization.<span />
The scientist that contributed to the declassification of Pluto as a planet is Mike Brown.
