Answer:
<h2>B.lysosomal enzyme</h2><h2>C. insulin
</h2><h2>d. ER protein
</h2>
Explanation:
Most proteins those that function in the cytosol (actin) or in the nucleus (DNA polymerase) are synthesized by free ribosomes.
Proteins that function within the endomembrane system, like in ER, Golgi complex etc (for example, lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes. These proteins pass through endomembrane system.
Protein those destined for the endomembrane system, are synthesized by ribosomes, they have signal in the growing polypeptide chain that act as a signal sequence.
Answer:
b Both travel at the same constant speed.
Explanation:
Answer:
like oceans, lakes and ponds are divided into four distinct zones: littoral, limnetic, profundal and benthic. Light penetrates the uppermost of these, the littoral, which contains floating and rooted plants. The other zones also each play unique roles in the ecosystem.Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.
