Explanation:
The planet Mars has two moons. Phobos and Delmos (i) phobos has period `7` hours, `39` minutes and an orbital radius of `9.4 xx 10^(3) km`. Calculate the mass of Mars. (ii) Assume that Earth and mars move in a circular orbit around the sun, with the martian orbit being `1.52` times the orbital radius of the Earth. What is the length of the martian year in days? `(G = 6.67 xx 10^(-11) Nm^(2) kg^(-2))`
Answer:
C - a geyser
Explanation:
When underground water and gases are heated by magma, they may shoot up to the surface as mud, water, or smoke, creating some very strange landscapes: Gases rise to the surface and form bubbling muddy pools of decomposed volcanic rock particles and water mixed together.
Answer:
RER is involved in protein synthesis, folding, transport and modification.
Explanation:
The Endoplasmic Reticulum is an organnelle found in eukaryotic cells. They are of two types; Rough Endoplasmic Reticulum and Smooth Endoplasmic Reticulum, so named based on the appearance of their surface. The Rough Endoplasmic Reticulum (RER) obtains it rough appearance from the membrane bound ribosomes attached to it.
Due to the ribosomes that attach to them during protein synthesis, their function is very much associated with protein synthesis. They are primarily involved in protein production, which would either remain in their lumen for further modification/processing called Glycosylation (adding sugar to proteins to form glycoproteins) or be transported through secretory vesicles to the Golgi apparatus. They also fold this proteins in their inner membrane structure called cisternae.
