Answer:
Small structures related to the lymphatic vessels, alone or in groups, that function as filters for the lymph and center of lymphocyte production are called lymph nodes (option c).
Explanation:
Lymph nodes, also called lymph ganglia, are structures of the lymphatic system that are found in the path of lymph-conducting vessels, similar to a bean.
The main functions of the lymph nodes are to filter the lymph that passes through them and to be the center of lymphocyte production, both functions related to the body's defenses and immune system.
On the occasion of an infection, the lymph nodes adjacent to the affected area can become swollen and painful, a sign that pathogens are being fought in them.
The other options are not correct because:
<em> a and d. </em><em><u>Cellular or tissue nodes</u></em><em> are not common terms in anatomy and yet, tissue nodule may refer to a nodular tumor.
</em>
<em> b. </em><em><u>Heart nodes</u></em><em> refer to the small structures that are responsible for nerve conduction and automation in that organ.</em>
Answer:
Well, by my reckoning, the first sentence they are putting Ralph on a sort of condition, not a way of reasoning.
The last one they try to intimidate Freddy comparing him to a coward.
The letter B sounds better. The speaker says something positive to Maryann, making her come up with a sense of being brave and make a good decision.
But, as I said before, it's just what comes to my mind. Let's wait for any other explanation. :)

Answer:
outer ear
Explanation:
The ear can be divided into three different structures: 1-the outer ear, 2-the middle ear, and 3- the inner ear. The outer ear can be defined as the external part of the ear, which is composed of cartilage and skin. The outer ear consists of the auricle or 'pinna' (i.e., the cartilaginous portion of the ear), and the external auditory meatus (also known as the ear canal). The outer ear acts to direct sounds and vibrations into the ear canal to the tympanic membrane. Moreover, the middle ear is a cavity between the outer and inner ear that functions to transmit sound energy from the ear canal to the cochlea. Finally, the inner ear acts to convert acoustic energy into nerve impulses, which are transmitted to the central nervous system.
The uric acid cycle is a cyclic adaptation of the process used for mammalian purine catabolism. Inosine monophosphate (IMP) is formed which reacts with pyrophosphate to form hypoxanthine and 5-phosphoribosylpyrophosphate (PRPP). This reaction is catalysed by hypoxanthine phosphoribosyltransferase (EC 2.4.
