1. The waste products of plant cells are carbon dioxide, water and oxygen. The carbon dioxide which is release during respiration is used up by photosynthesis process. The oxygen which is a by product of photosynthesis exist the plant cells through the stomata and root cell wall. Plant cells get rid of excess water via transpiration and guttation.
2. Protein synthesis within the cell is divided into two major phases, the transcription and the translation stages. In the transcription stage, the genetic information inside the DNA which is located inside the nucleus is transcribed into the mRNA, which then move out of the nucleus into the cytoplasm. In the cytoplasm, mRNA attached to the surface of the ribosomes and initiates the translation stage of protein synthesis. With the aid of tRNA and other elongation factors, a protein chain will be build up until a termination codon is reached, where the growing polypeptide chain will be terminated. The protein is then transported to the golgi apparatus which package the protein and send to the appropriate locations.

Answer from: Quest

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

When does a spring tide occur? question 9 options: they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur twice a year in the spring and fall. they occur on the date of the vernal equinox each year, no matter what stage the moon is in. this is why they are called spring tides. they occur when the sun, moon, and earth are at 45-degree angles from each other. this happens once every spring. they occur when the sun, moon, and earth are aligned. in spite of their name, these tides occur all year long.
