Answer:
DNA
It transmits genetic information to the next generation
Explanation:
In active protein translation and folding.
Rough endoplasmic reticulum is called rough because<span> it has many ribosomes on its wall making it look rough. RER is</span><span> involved mainly in protein production, folding, and quality control. Smooth endoplasmic reticulum is specialised in fats and steroids production. </span><span />

Hello There!
This is called the "Thermosphere"
The thermosphere is the biggest part of the Earth's atmosphere. This layer is very important because it protects us on earth from UV radiation. UV radiation is harmful for humans skin and their hair. It is also extremely hard to breathe in this layer because the thermosphere is made up of mostly nitrogen and oxygen.
Answer:
Gametogenesis is the formation of gametes, in males it is referred as spermatogenesis and in females it is called oogenesis.
Explanation:
Differences between spermatogenesis and oogenesis:
1. Spermatogenesis is formation of sperms from spermatogonia and oogenesis is formation of ova from oogonium.
2. Location: Production of sperms occur in testis and production of ova occurs in ovaries.
3. In males, spermatogenesis begins at puberty and its a continuous process till death whereas in females, oogenesis begins at fetal stages, it halts and rest of the process occurs after puberty till menopause.
4. Primary spermatocyte undergoes meiosis-I to form two secondary spermatocytes, whereas primary oocyte undergoes to M-I to form a single secondary oocyte with a polar body.
5. Meiosis-II results in the formation of 4 spermatids or spermatozoa, in females however M-II results in only one ovum and second polar body formation.
6. Overall we can say that single spermatogonium forms 4 spermatids whereas single oogonium forms only 1 ovum.
7. Sperms are motile where as ovum in non-motile.
