Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code
Explanation:
The ER makes proteins and the nucleus holds the DNA of the cell. So proteins are manufactured according to instructions encoded in the genes in the nucleus. These genes are now transcripted into RNA then leaves the nucleus and interacts with ribosomes on the ER, which now links amino acids together to form protein chains. The Cell Membrane is a selective barrier on the boundary of every cell. Its function is to allow the passage of oxygen, nutrients, and wastes to service the entire volume of th cell. The lysosomes are digestive organelles where macromolecules and other wastes are hydrolyzed by enzymes. Their main function is to process the molecules taken in through the cell membrane and to recycle won out cell parts. After ribosome synthesize proteins, the proteins are transported into the rough E.R. Then, proteins are enclosed into a vesicle and transported to the golgi apparatus, where processing, packaging, and transport of proteins is done. After the protein is processed, it will then bud off from the golgi apparatus (as vesicles) and transport to wherever it is needed. The nucleus is responsible for making the RNA, which is then sent to the E.R. Next, the E.R. sends the RNA to the ribosomes, where they link amino acids together to form protein chains. The E.R gets the RNA from the nucleus and sends it to the ribosomes to make proteins. The rough E.R specializes in protein synthesis, which means the ribosomes will attach to the E.R and synthesize the proteins. Next, the proteins enter the lumen space (interior of E.R) where they can be modified. Lastly, the proteins are sent off to the lumen of the smooth E.R.
Answer:
Phloem cells are hollow and nonliving, and they form a continuous pipeline that transports sugars.
hope this answer is correct ...
Answer:
Water, grass, air, plants, plastic, rock, soil, (organisms, fruits, vegetable, meat, foods with carbohydrates, lipids, and proteins) ----> just list a few and you'll be fine, do some research on the last one; one example is pasta, which contains carbs which are made up of carbon, hydrogen, and oxygen
Explanation:
basically everything is made up of oxygen, especially organisms
Answer:
Electron microscopes use a beam of electrons instead of beams or rays of light. Living cells cannot be observed using an electron microscope because samples are placed in a vacuum. ... the scanning electron microscope (SEM) has a large depth of field so can be used to examine the surface structure of specimens.

No Explanation Just Pure Common Sense
