I believe that the most logical explanation for this is that the right primary bronchus is wider than the left one (and the right lung is larger than the left lung), therefore the right lung receives slightly more carcinogenic cigarette smoke with each puff. In lung cancer. the cancer cells usually arise from the epithelium lining of large bronchus.

6. Glucose
7. Ribosomes
Explanation:
This question is describing the organelles found in a cell. An organelle is a structure that performs a specific FUNCTION (1) in a cell. There are different kinds of organelles with each possessing its own peculiar function. Some of them are as follows:
- NUCLEUS, which is regarded as the brain of a cell because it directs or controls a cell's activities just like the brain of an organism does.
- MITOCHONDRIA is an organelle that produces the energy storing compound called ATP (adenosine triphosphate), hence, it is called power house of the cell.
- CHLOROPLAST is an organelle found in plant cells that functions in the conversion of light energy (from sun) into GLUCOSE (chemical energy) in a process called PHOTOSYNTHESIS.
- RIBOSOMES is an organelle found in both prokaryotic and eukaryotic cells that serves as the site of PROTEIN production in a cell.
The sign of lead poisoning in children would be impaired development.
Lead is very toxic to the brain, so lead poisoning will be especially dangerous in children when the brain is developing at a high rate. Damage to the brain will cause the children to have an impaired development and growth, gastrointestinal pain, or neurological issue like seizure.
Answer:
The cells are connected by gap junctions.
Explanation:
A gathering of protein channels, which permits small molecules and ions to move between the neighboring cells is termed as a gap junction. The protein channels that form gap junctions comprise two connexons, of which one is situated in the membrane of one cell that combines and aligns with the connexon of the adjacent cell.
This association produces a spontaneous pathway, which permits the small molecules and ions to pass passively from one cell to another. The gap junctions are found in all the kinds of cells, however, they are not found in skeletal muscle, RBCs, and blood lymphocytes.
Thus, the passing of the fluorescent dye from one cell to another shows that the two cells are connected with the help of gap junctions.
