Answer: D.
The E. reticulum and Golgi bodies are concerned with secretion and synthesis of molecular substances e.g protein , lipids and steroid. Therefore these cellular organelles should contain Plasma B cells and Islets of Langerhans. for protein hormone synthesis(insulin) and antibodies production
Explanation:
Answer:
5. Dead animals sink to the sea floor and decompose, leaving their skeletons.
2. Mud and said fall to the seated, heat and pressure cover the sediment to rocks.
1. the skeleton is buried by sediment and slowly mineralized to stone.
3. Erosion takes place, expending the fossils.
6. The sea retreats of the rock beds we pushed up and are expened
4. The process repeats itself as more sediment falls and more animals die.

This is just my best guess, so please take it with a grain of salt! :')
gl on whatever assignment you happen to be completing, btw :3
Answer:
Many years ago scientists believed that protein, DNA is not the genetic material because of many reasons like DNA is made up of only four type of nucleotides while proteins are made up of 20 different types of amino acids. So the building blocks of protein are way high than DNA.
Most of the cellular function is performed by proteins, not DNA. The three-dimensional shape of protein is much higher than nucleic acid. So as protein heterogeneity was high therefore it was considered as a molecule of genetic information instead of DNA.
Sugar molecules, cells use carbon dioxide and energy from the sun to make sugar molecules. They are moved into the sieve elements (phloem cells) through active transport. Water follows the sugar molecules into the sieve elements through osmosis (since water passively diffuses into regions of higher solute concentration).
