This question is supposed to have a table showing species member tested and the type of cells tested and the results. Based on this table, the species member that would be unlikely to pass the gene mutation on to its offspring is species member 4: [Body cells (+) and Sperm (-)] Hope this helps.
Ans.
Cell-to-cell communication allows signalling of essential substances between the plant cells, which are surrounded by cell walls. The molecules used by plants for long-distance signalling are known as hormones, such as auxin, ethylene, and gibberelin.
These hormones are secreted by one plant cell and received by another plant cell, where it exerts it affect. Thus, the correct answer to be fill in the blank is 'option A). hormones.'
I think it’s C but I could be wrong
I believe that the answer to this would be polar and hydrophilic (soluble in water). The answer would be the third option. What makes the head of a phospholipid hydrophilic is that its polar head is negatively-charged and made by a phosphate group. Hope this helps.
