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.
The Earth's rotation does, like a basketball spinning
on the tip of Kobe Bryant's finger.
Since the Earth is somewhat bigger than a basketball,
it takes almost 24 hours to do one complete spin.

Image result for Why does the Moon appear red during a lunar eclipse?
A lunar eclipse takes place when the sun, Earth and moon line up in space. The moon passes through Earth's shadow. ... Bottom line: The moon can look red during a total lunar eclipse because of sunlight that's filtered and refracted by Earth's atmosphere
Object mass =mk<span>g
</span>acceleration due to gravity of Mars = gm m/
acceleration due to gravity on Earth ge=−9.8 m/
weight of an object on Earth=m×ge=350N
weight of an object on Mars=m×gm=134<span>N
</span>
m x gm = 134
m x ge = 350
gm = 134/350 x 9.8 m/ = 3.752 m/
