Answer:
D) The gland produces and secretes its product into the blood.
Explanation:
Endocrine glands are the ductless glands. They do not have ducts to deliver their secretions to the target cells but directly release them into the blood. The secretions of endocrine glands are called hormones. To be an endocrine gland, the mentioned long oval structure should lack ducts and release its hormone/s directly into the blood. For example, the thyroid gland is an endocrine gland and releases its hormone thyroxine directly into the blood to be carried to the target body cells.
Answer:
Neurons are made up of three major parts: a cell body, or soma The part of the neuron that contains the nucleus of the cell and that keeps the cell alive., which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.
The primary function of all lymph nodes is the production of lymphocytes, which help defend the body against microorganisms and against harmful foreign particles and debris from lymph before it is returned to the blood stream. The major clusters of lymph nodes are in six areas.
Answer:
B) When an electrically charged object comes close to an uncharged object, it will attract it.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
Any charged object - whether positively charged or negatively charged - will have an attractive interaction with a neutral object. Positively charged objects and neutral objects attract each other; and negatively charged objects and neutral objects attract each other.
