Dichotomous keys might seem difficult because they require accurate observations and understanding of specific biological vocabulary. However, with practice, usage of dichotomous keys can become easier. It's similar to learning a new language.
Dichotomous keys might seem challenging because they require a high level of attention to detail and understanding of specific biological terminology. However, with practice, they become easier to use. A dichotomous key is a tool used in biology to identify an unknown organism by going through a series of choices that lead the user to the correct name of a given item.
To correctly use a dichotomous key, you must carefully observe the organism in question and make accurate observations. Then, you follow the key, making decisions based on your observations. This often involves detailed, specific biological vocabulary and precise measurements which some students may initially find overwhelming.
However, remember that with practice and usage, becoming proficient with dichotomous keys is completely achievable. It's essentially like learning a new language! Once you get the hang of it, it can be a valuable tool in your biological studies.

Answer:
Hydrophobic molecules don't like water,just like the membrane.Since the membrane and these signaling molecules are made of the same thing,liquid,they can easily mix together.
Explanation:
Hydrophobic signalling molecules move right through the cell membrane to the target inside the cell.
