hope it helps
Metamorphic rocks are produced when rocks are affected to high pressures, high temperatures, hot mineral-rich fluids, or, more usually, any accumulation of these possessions. Thus, option B is correct.
What results in sedimentary rock into a metamorphic rock?If subjected to sufficient heat and pressure, sedimentary rocks like bituminous coal, limestone, and sandstone can undergo nonfoliated metamorphic rock formation, giving rise to anthracite coal, marble, and quartzite.
These kinds of conditions can be found deep inside the Earth or where tectonic plates collide.
Metamorphism, which occurs when magma interacts with the surrounding rock, is another process that can produce nonfoliated rocks.
Therefore, deep-buried rock that has been melted by incursion rock was lost to erosion and dumped in the ocean basin.

Kussmaul respirations are an indication that the body is
Answer:
Kussmaul respirations indicates the condition of acidosis and diabtetes ketoacidosis
Explanation:
Kussmaul respiration refers to the labored and deep breathing pattern. Adolph kussmaul introduced the term Kussmaul respiration.
This respiration refers to the form of hyperventilation in which the amount of carbon dioxide is decreased in the blood. The metabolic acidosis alters the normal pattern of breathing and results in rapid and shallow breathing. The Kussmaul respiration is most common in ketoacidosis.
Kussmaul respirations indicate the body's attempt to compensate for metabolic acidosis by hyperventilating to expel carbon dioxide and reduce acidity.
Explanation:Kussmaul respirations are a type of hyperventilation that is characteristically deep and labored. They are an indication that the body is compensating for metabolic acidosis, particularly when associated with diabetic ketoacidosis. In metabolic acidosis, the blood pH is low due to an excess of acid or a deficiency of bicarbonate. Kussmaul respirations occur as a respiratory compensation mechanism where the body attempts to correct this imbalance by exhaling more carbon dioxide (CO2), which is an acid when dissolved in the blood.
The increased respiratory rate and depth result from the body's need to lower blood acidity by releasing CO2. This compensatory mechanism can be observed in several conditions that cause metabolic acidosis, such as renal failure, and is often a serious sign that requires medical attention.
Describe the function of three areas of the brain (you choose which areas).
Answer:
Brain is the main coordination center of the body and regulates the proper functioning of the body. Brain is divided into three parts- forebrain, midbrain and hindbrain.
Cerebrum: Crerebrum is the largest part of brain and controls the language, communication ability, and the process of learning and memory of an organism.
Hypothalamus: Hypothalamus is located at the base of a brain. Hypothalamus releases various hormones, regulates the body temperature and manages the sexual behavior of an organism.
Thalamus: Thalamus is located above the brain stem and relay the neurons into the cerebral cortex. Thalamus regulates alertness, wakefulness and sleep of an organism.
Final answer:
The cerebrum controls higher brain functions and is divided into four lobes, each with distinct functions. The cerebellum coordinates muscle movements and maintains balance. The brain stem regulates vital life functions and connects the brain to the spinal cord.
Explanation:
The human brain is an intricate organ responsible for controlling many functions of the body, understanding complex thoughts, facilitating communication, and more. In the study of biology, it is essential to understand the different areas of the brain and their specific functions. Three critical areas of the brain are the cerebrum, cerebellum, and brain stem.
The cerebrum is the largest part of the brain and is responsible for higher brain functions such as thought and action. The cerebrum is divided into four lobes: the frontal lobe, responsible for reasoning, planning, parts of speech, movement, emotions, and problem-solving; the parietal lobe, which manages perception of stimuli related to touch, pressure, temperature, and pain; the temporal lobe, concerned with perception and recognition of auditory stimuli, memory, and speech; and the occipital lobe, dedicated to visual processing.The cerebellum is located under the cerebrum. Its main function is to coordinate muscle movements, maintain posture, and balance. This part of the brain is vital for performing activities that require fine motor skills, balance, and coordination, such as typing or playing a musical instrument.Connecting the brain to the spinal cord, the brain stem plays a crucial role in regulating vital life functions, including breathing, consciousness, and controlling heart rhythms. It is also responsible for various automatic functions necessary for survival, such as digestion and sleeping cycles.

During swallowing, the epiglottis, a leaf-shaped piece of cartilage, covers the trachea to keep food and liquids out. It assumes a fundamental part in keeping up with the aviation route clear.
It is a piece of the larynx and capabilities to shield the windpipe from suctioned food. At the point when you swallow, the retrogressive movement of the tongue powers the epiglottis to close over the entry of the larynx, actually keeping food and fluids from entering the respiratory parcel. An in-depth look at how the epiglottis works is provided below: After gulping, the tongue pushes the food towards the pharynx.The pharynx and larynx move up, permitting the epiglottis to swing lower and cover the trachea.By covering the windpipe, the epiglottis redirects food and fluids into the throat, the right pathway to the stomach. On the off chance that any food figures out how to move toward the windpipe, it disturbs the larynx, setting off areas of strength for a reflex to remove the material, in this manner safeguarding the lungs.Which nutrient is most closely related to the liver's ability to produce necessary clotting factors?

During the _______ phase, the muscle is returning to resting length.
Answer:
The correct answer is: Eccentric phase.
When talking about movement, we are talking about the activation of muscle fibers in order for this process to happen. In order for this to happen, motor neurons must activate the phases of muscle excitation, contraction and relaxation, so that the sarcomeres, and thus the fibers, can generate movement.
In essence, there are three stages, or phases, to complete muscle movement: the concentric phase, which is when the muscle fibers are excited and begin the process of contraction. This means the muscle fibers will contract and generate movement, generating a shortening. Then we have the isometric stage, a moment in which there is no longer any more shortening of the muscle fibers, so basically, the movement is held and there is no further contraction, but neither is there relaxation of the muscle fibers. Finally, we have the eccentric phase. This phase is characterized precisely because it is the moment when the muscles begin to return to their resting position.

A) renal corpuscle
B) afferent arteriole
C) nephron loop (loop of Henle)
D) filtration membrane
E) juxtaglomerular complex
Answer:
E. juxtaglomerular complex
Explanation:
Macula densa cells are the columnar tubule cells. They are present in the wall of afferent arterioles. The modified fibers of smooth muscles present in the lining of the afferent arteriole are called juxtaglomerular cells.
The juxtaglomerular cells and macula densa cells together make the juxtaglomerular apparatus, also called juxtaglomerular complex. The function of the juxtaglomerular apparatus is to maintain the blood pressure of kidneys.
Answer:
The correct answer is E) juxtaglomerular complex
Explanation:
The smooth muscle cells of both the afferent and efferent arterioles are swollen and contain dark granules. These cells are called Juxtaglomerular cells. These cells secret Renin which convert angiotensinogen into angiotensin.
The epithelial cells of the distal convoluted tubules that comes in contact with the afferent and efferent arterioles are more dense than the other tubular cells and are collectively called muscula densa. The cells of the mascula densa may function as chemoreceptors; feeding information to the juxtaglomerular cells. The juxtaglomerular cells and macula densa together form juxtaglomerular complex.
