Answer:
They cannot use the reasoning, "Dolphins and Ichthyosaurs form a paraphyletic group."
Explanation:
This is because they always form a monophyletic goup. Both of the species have specific morphological similarities that are enough to consider them in monophyletic group instead of a divergent paraphyletic.

Answer:
The system of nerves that govern reflexes, glands, the iris of the eye, and activities of interior organs that are not subject to voluntary control is called the <u>autonomic nervous system</u>
Explanation:
The autonomic nervous system is the involuntary division of the nervous system. It is composed of nerve cells that are related to the innervation and control of visceral organs, smooth muscle and secretory glands. It is divided into two systems, the sympathetic nervous system, which is responsible for activating most of the body's organs; and the parasympathetic nervous system, which is responsible for relaxing the activity of most organs, except those related to digestion.
The autonomic nervous system is responsible for regulating the involuntary visceral functions of the organism. Also, it's responsible for the maintenance of body homeostasis and the body's adaptation responses to variations in the external and internal environment. Thus, it helps to control, among other functions, blood pressure, heart rate, urinary emission, sweating, body temperature, among others. Most of the functions of the system are unconsciously regulated by means of visceral reflexes.

Answer:
Mesophyll and bundle sheath cell.
Explanation:
C4 pathway is also known as hatch slack pathway it is a photosynthetic process in some plants. In this pathway carbon is extracting from carbon dioxide to able to use in sugar and other biomolecules. C4 is known as four carbon molecules which is the 1st product of this type of carbon fixation.
In this pathway rubisco enzyme works in the environment where lots of carbon dioxide and very little oxygen present. CO2 is transferred via malate or aspartate from mesophyll cells to bundle sheath cells. In bundle sheath cell CO2 is released by malate decarboxylation.
C4 plants use PEP carboxylase to absorb more amount of CO2 in the mesophyll cells. Phosphophenolpyruvate (PEP) which is 3 carbon molecule binds with CO2 and make oxaloacetic acid, it forms than malate, 4carbon molecule. Malate enters through a plasmodesmata into bundle sheath cell and release the CO2.
