Examples of Replacement level in the following topics:
-
- When the fertility rate is at the replacement level, a population will remain stable, neither growing nor shrinking.
- However, when the fertility rate deviates from the replacement level, the size of the population will change.
- Fertility rates above the replacement level will cause the population to grow; fertility rates below the replacement level will cause the population to shrink.
- All of the nations of East Asia - with the exceptions of Mongolia, the Philippines, and Laos - have fertility rates below replacement level.
- Western Europe also is below replacement.
-
- Choosing a significance level for a test is important in many contexts, and the traditional level is 0.05.
- A part inside of a machine is very expensive to replace.
- If we don't have sufficient evidence to reject H 0 , we would not replace the part.
- It sounds like failing to fix the part if it is broken (H 0 false, H A true) is not very problematic, and replacing the part is expensive.
- Thus, we should require very strong evidence against H 0 before we replace the part.
-
- Boundless provides educators with materials that can replace textbooks, on a platform that is comprehensive and flexible.
- Boundless courseware is primarily used at the introductory college level, but our platform and content can be adapted to a wide range of levels.
- The content covered by our books is equivalent to what would be covered in a 101-level course for that subject.
- While Boundless textbooks are designed with introductory college classes in mind, in the high school setting, this translates to AP-level classes, which are intended to serve as equivalent to first-year university courses.
- Boundless has broad, but thorough coverage of a variety of AP subjects that are already at the reading and content level that these classes are designed to meet.
-
- As the follicles grow, they begin releasing estrogens and a low level of progesterone.
- The level of estrogen decreases when the extra follicles degenerate.
- The endometrium begins to regrow, replacing the blood vessels and glands that deteriorated during the end of the last cycle.
- The level of estrogen produced by the corpus luteum increases to a steady level for the next few days.
- Rising and falling hormone levels result in progression of the ovarian and menstrual cycles.
-
- During hormone replacement therapy the patient receives hormones either as a supplement or substitution to the natural hormone.
- Common forms of hormone replacement therapy include:
- Hormone replacement therapy for menopause is based on the idea that the treatment may prevent discomfort caused by diminished circulating oestrogen and progesterone hormones, or in the case of the surgically or prematurely menopausal, that it may prolong life and may reduce incidence of dementia It involves the use of one or more of a group of medications designed to artificially boost hormone levels.
- This includes female-to-male and male-to-female hormone replacement therapy.
- Estrogens have been extensively used in hormone replacement therapies in women.
-
- Here, zinc is more active than copper because it can replace copper in solution.
- The blue color of the solution diminishes as copper(II) ion is being replaced.
- An old-fashioned way of expressing this is to say that "zinc will replace copper from solution."
- Note that the table also takes the replacement of hydrogen (H2) into account.
- Although H2 is not a metal, it can still be "replaced" by some strongly reducing metals.
-
- Dialysis is a process of removing waste and excess water from the blood to provide an artificial replacement for lost kidney function.
- It is used primarily to provide an artificial replacement for lost kidney function in people with renal failure.
- The dialysis solution has levels of minerals like potassium and calcium that are similar to their natural concentration in healthy blood.
- For another solute, bicarbonate, dialysis solution level is set at a slightly higher level than in normal blood, to encourage diffusion of bicarbonate into the blood, to act as a pH buffer to neutralize the metabolic acidosis that is often present in these patients.
- The levels of the components of dialysate are typically prescribed by a nephrologist according to the needs of the individual patient.
-
- As individuals age, bone resorption can outpace bone replacement, which can lead to osteoporosis and fractures.
- Calcium-sensing membrane receptors in the parathyroid gland monitor calcium levels in the extracellular fluid.
- Low levels of calcium stimulate the release of parathyroid hormone (PTH) from chief cells of the parathyroid gland.
- High levels of calcium in the blood, on the other hand, lead to decreased PTH release from the parathyroid gland.
- As people get older, the rate of resorption tends to exceed the rate of replacement, leading to conditions like osteoporosis.
-
- A volume expander is a type of intravenous therapy that provides fluid replacement for the circulatory system.
- When blood is lost, the greatest immediate need is to stop further blood loss, then lost volume must be replaced.
- It may be used for fluid replacement.
- In extreme cases, patients have survived with a hemoglobin level of about 1/7 the normal (i.e. 2 g/dl), although levels this low are very dangerous.
- When blood loss is significant, the red blood cell level ultimately drops to a level that is too low for adequate tissue oxygenation.
-
- The human body maintains constant levels of glucose throughout the day, even after fasting.
- During long periods of fasting, glucose levels are reduced only very slightly.
- Because this ultimately lowers blood glucose levels, insulin is secreted to prevent hyperglycemia (high blood sugar levels).
- Negative feedback between insulin and glucagon levels controls blood sugar homeostasis.
- Diabetes is normally treated with insulin injections, which replaces the missing negative feedback of normal insulin secretions.
