How much water is reabsorbed back into the blood during reabsorption?
almost none
20 %
50%
80%
Answers
Answer: C) 80%
Explanation: The process by which the nephron takes water and solutes from the tubular fluid and returns them to the circulating blood is known as REABSORBPTION OR TUBULAR REABSORBPTION.
The reason it is called reabsorption and NOT absorption is that these substances have already been absorbed (especially in the intestines ) and the body is reclaiming them from a postglomerular fluid stream that is about to turn into urine.

Eighty-five to ninety percent of all intervertebral disk herniations occur at what two locations?
Answers
85–90% of all intervertebral disc herniations happen at the disc between L4 and L5 or L5 and S1, making the lower back particularly susceptible.
An issue with one of the rubbery cushions (discs) that lie in the spaces between the vertebrae that make up your spine is referred to as a herniated disc.
A spinal disc has a tougher, rubbery exterior covering a soft, jelly-like interior (nucleus) (annulus). A herniated disc, also known as a slipped disc or a ruptured disc, happens when a portion of the nucleus pushes through a tear in the annulus. Although a herniated disc can develop anywhere along the spine, it most frequently does so in the lower back. A herniated disc may cause pain, numbness, or weakness in an arm or leg, depending on where it is located. Many people with herniated discs don't experience any symptoms.

It allows seeds to reside in the gut until conditions are appropriate for germination. It ensures that flowers of these plants will be pollinated. It allows the seeds to be dispersed into other areas. It provides a source of nutrients for the germinating seed.
Answers
The advantage for plants having undigestible seeds is that it allows seeds to reside in the gut until conditions are appropriate for germination.
Fruits are a source of nutrition for animals that consume them, and they are also a means of seed distribution for plants that produce them. Many types of plants generate fruit that is consumed by animals; nevertheless, the seeds of such plants are usually indigestible. As a result, the seeds can be dispersed into new areas by animals that eat the fruit.
However, having undigestible seeds provides a distinct benefit to plants: it allows seeds to reside in the gut until conditions are appropriate for germination, which aids in seed growth and germination.

Organelle I is the ribosome, which is responsible for protein synthesis. Organelle III is the mitochondrion, which is involved in energy transformation and energy production through cellular respiration.
Organelle I, which is labeled as the ribosome, is responsible for protein synthesis. Ribosomes are involved in the process of translation, where they read the mRNA (messenger RNA) and assemble amino acids into polypeptide chains, ultimately forming proteins.
Organelle III, which is not specified in the question, cannot be identified based on the provided information. However, if we assume it refers to mitochondria (as labeled with Roman numeral VI), then its function is energy production.
Mitochondria are the powerhouses of the cell and are involved in cellular respiration, a process that generates ATP (adenosine triphosphate), the primary energy currency of the cell.
Therefore, the correct functions for organelle I (ribosome) are protein synthesis, and for organelle III (mitochondria) are energy production.

In addition, include at least two quotes from the text to support your argument. Don’t forget to sum it all up with a concluding sentence.
Claim:
Evidence and Reasoning:
Directions: Read the prompt below. Then, write a well-developed argument to support or reject the claim.
Claim: Zealandia should be classified as a geological continent, rather than an oceanic plate with a collection of continental islands, fragments, and slices.
Answers
Explanation:
region of the southwest Pacific Ocean is made up of continental crust. The region has elevated bathymetry relative to surrounding oceanic crust, diverse and silica-rich rocks, and relatively thick and low-velocity crustal structure. Its isolation from Australia and large area support its definition as a continent—Zealandia. Zealandia was formerly part of Gondwana. Today it is 94% submerged, mainly as a result of widespread Late Cretaceous crustal thinning preceding supercontinent breakup and consequent isostatic balance. The identification of Zealandia as a geological continent, rather than a collection of continental islands, fragments, and slices, more correctly represents the geology of this part of Earth. Zealandia provides a fresh context in which to investigate processes of continental rifting, thinning
Earth’s surface is divided into two types of crust, continental and oceanic, and into 14 major tectonic plates (Fig. 1; Holmes, 1965; Bird, 2003). In combination, these divisions provide a powerful descriptive framework in which to understand and investigate Earth’s history and processes. In the past 50 years there has been great emphasis and progress in measuring and modeling aspects of plate tectonics at various scales (e.g., Kearey et al., 2009). Simultaneously, there have been advances in our understanding of continental rifting, continent-ocean boundaries (COBs), and the discovery of a number of micro-continental fragments that were stranded in the ocean basins during supercontinent breakups (e.g., Buck, 1991; Lister et al., 1991; Gaina et al., 2003; Franke, 2013; Eagles et al., 2015). But what about the major continents (Fig. 1)? Continents are Earth’s largest surficial solid objects, and it seems unlikely that a new one could ever be proposed.

Hammer equal area projection.
The Glossary of Geology defines a continent as “one of the Earth’s major land masses, including both dry land and continental shelves” (Neuendorf et al., 2005). It is generally agreed that continents have all the following attributes: (1) high elevation relative to regions floored by oceanic crust; (2) a broad range of siliceous igneous, metamorphic, and sedimentary rocks; (3) thicker crust and lower seismic velocity structure than oceanic crustal regions; and (4) well-defined limits around a large enough area to be considered a continent rather than a microcontinent or continental fragment. The first three points are defining elements of continental crust and are explained in many geoscience textbooks and reviews (e.g., Holmes, 1965; Christensen and Mooney, 1995;

Alternatives to pesticides include all of the following except:

Answers
The correct answer is "fertilizer." Alternatives to pesticides include natural pesticides, planting non-host crops nearby to lure pests away, and crop rotation.
These methods aim to control pests and diseases in agricultural settings using ecological and sustainable practices. However, fertilizers are not an alternative to pesticides as they primarily provide essential nutrients to plants and do not directly target pests or diseases. Fertilizers are used to improve plant growth and productivity but do not have inherent pest-control properties. Applying appropriate amounts of fertilizer can promote healthy plant growth and strengthen the plant's natural defense mechanisms, making them more resilient to pests and diseases. Robust and healthy plants are often less susceptible to pest infestations. Additionally, fertilizer application can support the growth of beneficial organisms, such as predatory insects or microorganisms, which can help control pest populations.

Answers
The demand for wood affects species in other parts of the world in multiple ways. As the demand for wood increases, more trees are cut down, leading to deforestation and habitat loss.
This affects the species that live in these habitats by reducing their food and shelter supply, which can lead to population declines and even extinction in some cases. Additionally, the trade of wood often involves illegally obtained wood, which can further threaten species by increasing the rate of deforestation and habitat loss.
As a result, the demand for wood can threaten biodiversity in other parts of the world by leading to habitat loss, population declines, and even species extinction. Furthermore, the illegal trade of wood can further compound these threats to species in other parts of the world.

There are two continents with an ocean between them. Today the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago when this type of organism was alive, we know it lived in only one place. The geologist is using fossils as evidence to argue that the two contients used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
Answers
Answer:
A. Through geologic forces leading to continental drift.
B. It can take up to millions of years.
Explanation:
A. Continents rest on tectonic plates (a large slabs of rock). The plates are usually moving and interacting with one another. Seafloor spreading zones and giant rift valleys are the sites where tectonic activity are done.
However, in the process of seafloor spreading, molten rock emerges from within the Earth and produces an oceanic crust (a new seafloor) to the edges of the old one. Seafloor spreading occurs along giant underwater mountain ranges (also referred to as mid-ocean ridges).
Then, as the seafloor grows wider, the continents on opposite sides of the ridge move away from each other over time to experience a define continental drift.
B. The seafloor spreading rates is as low as 2.5 centimeters per year and take up to millions of years to see a well defined drift.
what does an analyst have to measure to determine the angle of blood spatter and the position of the victim?
Answers
An analyst has to measure the length and width of the spatter to determine the angle of the blood spatter and the position of the victim.
Examining total size, form, distribution, and other properties of bloodstains at a crime scene is the study of blood spatter, commonly referred to as blood spatter pattern analysis. Analysts can determine the elongation and impact angle of the blood droplets by examining the length and width of the blood spatter. The length-to-width ratio, or "elongation" of the bloodstains, might reveal information about the angle at which the droplets struck the surface.
The analyst can then use mathematical procedures and trigonometry to calculate the angle of impact based on the elongation. The location and movement of the victim or any other items involved can be used to recreate the sequence of events that resulted in the production of the blood spatter pattern from this viewpoint.

Answers
Cellular respiration is the mechanism by which organisms merge oxygen with food molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding carbon dioxide and water as waste products.
STAGES OF CELL RESPIRATION:
1. Glycolysis: Glycolysis involves the chemical metamorphosis of glucose, a six-carbon sugar. It ultimately degrades into two motes of pyruvate, a three-carbon organic patch. ATP is produced in these responses, and NAD is converted to NADH.
2. Pyruvate oxidation: occurs when each pyruvate produced by glycolysis enters the mitochondrial matrix, the inmost cube of the mitochondria. It's also converted into acetyl CoA, a two-carbon patch bound to Coenzyme A. Carbon dioxide is emitted, and NADH is produced.
3. Citric acid: The cycle of citric acid. The acetyl CoA produced in the final step combines with a four-carbon patch and undergoes a series of responses, ultimately regenerating the four-carbon starting patch. Carbon dioxide is released as ATP, NADH, and FADH2 are produced.
4. Oxidative Phosphorylation: The final stage of aerobic cellular respiration is oxidative phosphorylation. The electron transport chain and chemiosmosis are the two substages of oxidative phosphorylation. Energy from the former stages of cellular respiration, NADH and FADH2, is used to produce ATP in these stages.
