In the α helices of transmembrane proteins, the hydrophobic side chains face the outside of the membrane-spanning helix.
Transmembrane proteins are a type of integral membrane protein that spreads throughout the cell membrane. Many transmembrane proteins act as gates that allow the transport of certain substances across the membrane.
Transmembrane proteins basically act as gates or docking sites that allow or prevent substances from crossing the cell membrane.
Transmembrane proteins penetrate the entire plasma membrane. Transmembrane proteins are found in all types of biological membranes. Monotopic proteins are permanently attached to the membrane from only one side

Answer:
the questions are basically telling you to look at the diagrams you have about the animals and asking for observations you can make about them
Explanation:
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.
The autonomic nervous system is involved in controlling a, c, d, e.
what is the Autonomic nervous system?
The peripheral nervous system's autonomic nervous system (ANS) is in charge of regulating critical processes like digestion, breathing, and heartbeat. In the acute stress response, it collaborates with the endocrine system to get the body ready for fight or flight.
Between the central nervous system and the internal organs, the autonomic nervous system acts as a relay. It regulates the exocrine and endocrine glands, smooth muscle, the heart, the lungs, and the heart. These organs are mostly under the autonomic nervous system's control, which is unconscious.
Hence from the above information, we get to understand that ANS helps to control systems, not in our control hence it will regulate all the given options except skeletal muscles as they are under control.
