Dialysis is a procedure used significantly in clinical biology to eliminate the nitrogenous wastes from the body of patient in case of kidney failure.

Kidney is main organ for excretion. In kidney failure, the waste products are not eliminated through urine. Accumulation of toxic products in the blood could therefore lead to sepsis and can even be fatal.

In such case, dialysis is carried out, in which blood is purified through a dialyzer that works as kidneys artificially.

In this procedure, blood from the vein flows into the dialysing unit containing an anticoagulant and all the components of the blood plasma.

The purification of blood takes place on the basis of difference in concentration gradient and hence the filtered blood then enters into the blood through an artery.

Therefore, dialysis is a boon for patients with kidney failure and it increases the rate of survival in such patients.

Gymnastics is considered the purest sport because it requires a combination of physical abilities and artistic expression. It is an individual sport where athletes are solely responsible for their performance. Gymnastics has a long history and is an important part of the Olympic Games.

Explanation:

Gymnastics is often considered to be the purest of all sports or athletic activities because it requires a combination of strength, flexibility, agility, balance, and grace. In gymnastics, athletes must perform highly technical movements with precision and control, showcasing their physical abilities and artistic expression. Unlike team sports, where success can depend on the performance of others, gymnastics is an individual sport where athletes are solely responsible for their own performance.

Additionally, gymnastics has a long history dating back to ancient Greece, where it was an important part of the Olympic Games. The ancient Greeks valued physical excellence and believed that gymnastics was a way to honor the gods. The modern Olympic Games, which were inspired by the ancient Games, continue to include gymnastics as a core event, further establishing its significance as a pure and respected sport.

Answer:

evergreen broadleaf trees and low shrubs and vines.

Explanation:

The rain forests are present near the equator for which they are also called tropical rainforest. Here they get a sufficient amount of light and water. There is no dry condition here. The vegetation present here are evergreen and there is a competition among the plants to get sufficient light. Therefore, the plants are tall having broadleaf in the canopy layer of the forest. At the base of the forest, there are shrubs, bushes are present. There are many vines and creepers are found. They climb the tall trees to get the light. These are the adaptation of the plants to survive in this humid condition. As there is no dry condition there is no fall in plants and they are evergreen. The Amazon rainforest of South America, Madagascar, Andaman and Nicobar Islands are coming under the tropical rainforest. The Amazon rainforest is also called the lungs of the earth.

Sexual development during puberty is affected by several hormones including the GnRH (from hypothalamus), LH and FSH (from anterior pituitary gland), and testosterone or estrogen (from gonads). The initiation of changes that occur in puberty is due to changes in sensitivity to these hormones. This eventually leads to the maturation of the reproductive system and development of secondary sex characteristics.

The process of puberty involves a complex interaction of hormones. These include hormones from the hypothalamus (GnRH), anterior pituitary (LH and FSH), and the gonads (testosterone or estrogen). They work together to control the maturation of the reproductive systems and the development of secondary sex characteristics. When an individual approaches puberty, the sensitivity of the hypothalamus and pituitary to negative feedback decreases and the sensitivity of the gonads to FSH and LH signals increases. As a result, levels of LH and FSH rise, prompting the enlargement and maturation of the gonads, and commencement of spermatogenesis and folliculogenesis. These changes lead to significant increases in either estrogen or testosterone.

Final answer:

The soil rich in organic matter that can be burned when dried is called peat, which forms in swampy areas and is the precursor to coal.

Explanation:

Soil that is so rich in organic matter that it can be burned is called peat. Peat is a type of soil that consists of partially decayed plant material and is found in swampy areas. This organic material accumulates over time, especially in places where decomposition is slow, such as bogs and swamps, forming what is known as Histosols. When dried, peat can be used as a fuel source because the energy captured in photosynthesis remains in the peat, as the plant material has not fully decomposed. Over millions of years, peat can be compressed and heated to eventually become lignite and then anthracite, which are forms of coal.

The correct answer to the question is a. Peat.

Answer:

a) Right scale for right entity to be measured.

b) Minimum measured value

Explanation:

The first and foremost essential requirement for making a good set of measurements is to use a scale of measurement with which the target unit can be measured for example you cannot measure volume by a scale thus only a linear unit can be measured by a scale.

The second important thing is to look into the scale for its least measurement value as this will help to decide the right application of scale being used for measurement.

The concept of past life on Mars is emerging due to findings of water and organic substances in Martian meteorites, hinting at potential ancient life. Scientists explore the similarity in early conditions between Earth and Mars and the possibility of life being transferred via meteorites. Research and upcoming missions aim to investigate this hypothesis further.

The idea that there was once life on Mars is considered an emerging idea primarily because of the discovery of water and organic compounds in Martian meteorites, which suggests the possibility of ancient Martian oceans and perhaps life. The meteorite ALH84001 found in Antarctica has been intensely analyzed and provided evidence that bolsters the hypothesis of past life on Mars. One of the most important lines of inquiry is whether Mars could have supported life around 4 billion years ago, with conditions similar to those of early Earth.

Further evidence supporting this idea includes the identification of carbon-rich substances within Martian meteorites, indicating biological processes that may have occurred on Mars. Scientists also consider the possibility that life could have been "seeded" on Earth from Mars through meteorite transfers. Ongoing and future missions aim to return Martian samples, particularly from sedimentary rocks at sites that once held water, to conduct even more powerful searches for Martian life in Earth laboratories.

Research such as the Miller-Urey experiments and discoveries of ancient microbial life on Earth provide context for these Martian studies, showing that organic compounds and life forms could originate under the right conditions. Therefore, the search for life on Mars is a significant scientific endeavor, challenging our understanding of life's origins in the universe.

The energy source that transforms carbon dioxide and water into chemical energy in plants and other autotrophs is solar energy through the process of photosynthesis. This process creates glucose and oxygen, stored chemical energy necessary for various forms of life.

The energy source used to transform carbon dioxide and water into chemical energy by plants and other autotrophs is solar energy. This conversion takes place during a vitally important biological process called photosynthesis. Using the radiant energy from sunlight, photoautotrophs such as plants, algae, and photosynthetic bacteria absorb solar energy and convert it into chemical potential energy in the form of glucose and oxygen. This process involves creating ATP (adenosine triphosphate) and NADPH, molecules that store energy which is used to synthesize complex organic molecules like glucose. The stored chemical energy in these sugar molecules is essential for life on Earth, powering the metabolism of organisms and providing a source of oxygen necessary for many living beings.

Photosynthesis is not only critical for the autotrophs themselves but also serves as the foundation of energy for most of Earth's ecosystems, particularly those defined by grazing food webs. The conversion of light energy to chemical energy during photosynthesis is a fundamental aspect of energy transfer within and between these ecosystems.

bicarbonate can act as an acid or a base (i.e., donate or accept hydrogen ions) depending on conditions.

Under present-day conditions, these reactions buffer the pH of surface seawater at a slightly basic value of about 8.1 (above the neutral value around 7.0). At this pH, the total dissolved inorganic carbon (DIC ~ 2 mM) consists of approximately 1% CO2, 90% HCO3–, and 9% CO32– (Figure 2.1). The total boric acid concentration (B(OH)4– + B(OH)3)) is about 1/5 that of DIC. As discussed in section 2.2, increases in CO2 will increase the H+concentration, thus decreasing pH; the opposite occurs when CO2 decreases. We note that isotope fractionation between B(OH)3 and B(OH)4–is used for estimating past pH values
