Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
Answer:
4. Absorb extra fluid between the cells
Explanation:
The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.
Answer: Option E. All the statements are correct.
Explanation:
Thyroid gland is an endocrine gland that is found in front of the neck, it consists of two lobes connected by isthimus. It is in front of the neck lying against and around the front of larynx and trachea. Thyroid gland secretes three hormones which are thyroxine, triiodothyronine and calcitonin. Thyroxine and trio doth tribune are thyroid hormone. The parathyroid glands are tiny structures found in the thyroid gland. A thick connective tissue separates the parathyroid glands from thyroid tissues. The thyroid gland is controlled by thyroid stimulating hormone called thyrotropin which is released from the anterior pituitary gland which triggers the release of thyroid hormones.
