What occurs when an earthquake causes a sudden vertical change in the sea floor? a. isostasy b. soil creep c. sheet erosion d. a tsunami
apex D. a tsunami
Answer: d. Tsunami
A tsunami is a natural disaster in which high speed waves generate in the ocean due to the gravitational force exerted by the moon on the water of the ocean resulting in flood. But these may also occur because of the underwater earthquakes, landslides and volcanic eruptions. All these events causes changes in the sea floor.
Therefore, tsunami will occur when an earthquake causes a sudden vertical change in the sea floor.

What are sedimentary rocks?In comparison to metamorphic and igneous rocks, which are generated deep beneath the Earth, sedimentary rocks are formed on or around the surface of the planet. Erosion, weathering, dissolution, precipitation, and lithification are the main geological processes that result in the formation of sedimentary rocks.
The impacts of wind and rain, which gradually reduce huge boulders into smaller ones, are included in erosion and weathering. Boulders and even mountains become sediments, such as sand or mud, as a result of erosion and weathering. Chemical weathering, or dissolution, is one type of weathering. This method uses slightly acidic water to gradually wear away stone. The building blocks for new, sedimentary rocks are produced by these three processes.
New rocks or minerals are created through the processes of precipitation and lithification. Precipitation is the process through which chemicals that precipitate from water give rise to rocks and minerals. For instance, when a lake evaporates over thousands of years, mineral deposits are left behind; this is what happened in California's Death Valley. The process through which clay, sand, and another sediment on the bottom of the ocean or even other bodies of water are gradually compressed into rocks because of the weight of the sediments above them is known as lithification.
Therefore the correct option is D.

Explanation:
one of the effects of hurricane Katrina, which devastated new orleans in 2005 was the death of almost all of the plants in flooded areas. initially, toxic chemicals and bacteria were suspected as a possible cause. Scientist later determined that the salt concentration in the floodwater caused the plants to die. The death of the plants was most likely due to? A. water moving into plant cells from the surrounding environment. B. Water moving out of plant cells into the surrounding environment.
C. both water and salt moving from plant cells into the surrounding environment.
D. both water and salt moving into plant cells from the surrounding environment.
B. Water moving out of plant cells into the surrounding
environment is the cause of the plants death in flooded areas in New Orleans in
2005 because of the hurricane Katrina. Since the floodwater has a salt
concentration that penetrates into the plant cells.
The plants in the flooded areas of New Orleans died after Hurricane Katrina in 2005 due to the high salt concentration in the floodwaters. This caused water to move out of the plant cells (plasmolysis) leading to dehydration and death.
Explanation:The death of the plants in the flooded areas of New Orleans after Hurricane Katrina in 2005 was most likely due to B: Water moving out of plant cells into the surrounding environment. This effect is largely related to the concept of osmosis. Essentially, the high salt concentration in the floodwaters created a hypertonic environment, causing the water in the plant cells to move out towards the saltier environment in a bid to balance the concentration. This process, known as plasmolysis, results in dehydration and ultimately the death of the plant.
Furthermore, some plant species, known as halophytes, can tolerate such salty conditions due to special adaptations. However, the majority of the plants in the flood-hit areas of New Orleans were not halophytic, thus could not withstand the high salt concentrations. This demonstrates that while some organisms can well regulate the effects of osmosis, many cannot when faced with extreme conditions.

The main hazard from a quiet volcanic eruption is a. volcanic gases. b. lava flows. c. geysers. d. pyroclastic flows. Please select the best answer from the choices provided
The main hazards from a quiet volcanic eruption are volcanic gases and lava flows. These can have substantial long-term effects on the atmosphere, climate, and terrestrial landscapes. Explosive phenomena like geysers and pyroclastic flows are more characteristic of violent eruptions.
Explanation:The main hazard from a quiet volcanic eruption is not geysers or pyroclastic flows, as these usually occur in explosive eruptions. Instead, the primary dangers are a. volcanic gases and b. lava flows. Volcanic gases, such as water vapor, carbon dioxide, and sulfur dioxide, are released massive quantities during eruptions. These gases can have long-term effects on the atmosphere and climate. Furthermore, even quiet eruptions can produce enormous amounts of lava. Lava flows can spread rapidly from long cracks during an eruption, forming vast lava plains, like those that exist on the Moon and some of the other terrestrial planets. These flows can cover large areas, causing significant harm to human settlements and ecosystems.

Bone marrow transplant taken from a donor and infused through the central vein is coded to what icd-10-pcs code
A bone marrow transplant is coded in the ICD-10-PCS with a specific seven-character alphanumeric code, which should be referred to in the ICD-10-PCS manual. The code varies depending on procedure details but ensures matching of donor and recipient to avoid GVHD.
Explanation:The ICD-10-PCS (International Classification of Diseases, Tenth Revision, Procedure Coding System) code for a bone marrow transplant taken from a donor and infused through the central vein involves a specific code that identifies the type of procedure. During the procedure, it is crucial to have a matching donor to prevent tissue rejection and minimize the risk of Graft-versus-Host Disease (GVHD). After a matching donor is found, the patient's own bone marrow is destroyed through radiation and/or chemotherapy, followed by the intravenous infusion of donor bone marrow stem cells. These stem cells then colonize the recipient's bone marrow to restore its function.
Based on the information provided, it seems like the index terms provided do not directly correlate with a specific ICD-10-PCS code. For the purposes of coding, one would need to refer to the ICD-10-PCS code manual to locate the precise procedure code, which is typically a seven-character alphanumeric code. The provided terms such as bone marrow transplant (792, 794) could refer to the index of a coding manual but not the exact code itself that should be used.

Answer:
Organisms use energy in two steps:
Conversion of food into adenosine triphosphate (ATP):Organisms harness the chemical energy of the food and convert it into more usable for that is, ATP. The set of chemical reactions involved in this process is termed as cellular respiration. It may include glycolysis, Krebs cycle, electron transport chain, oxidative phosphorylation.
ATP hydrolysis:Organisms use the energy associated with ATP through a hydrolysis reaction. The hydrolysis of ATP releases ADP, Pi, and energy. ADP is further hydrolyzed to produce AMP, Pi, and energy.
Which best describes when our scientific body of knowledge was developed? A. It was developed in ancient times. B. It was developed in the 20th century. C. It was developed by scientists throughout history. D. It was developed in the last 300 years.
Answer:
The correct answer will be option C.
Explanation:
Scientific studies started in ancient times but it has been developed throughout time as the study of science and development of scientific knowledge dates back from ancient times. In ancient times scientists were referred to as "natural philosophers" which tried to answer many natural phenomenon and made an attempt to classify the living world like Aristotle, Thales, Theophastrus but the scientific method has been employed since middle ages by philosophers like Ibn al-Haytham in 11th century and is considered as the first scientist as he invented the pinhole camera, studied rainbows and eclipses, and discovered the laws of refraction. The scientific revolution took place after 17th-century in Europe which led to the development of modern science.
Thus, option C is the correct answer.
The correct answer is C. It was developed by scientists throughout history.
Explanation:
Science is the field that studies the world and mos elements on it through the scientific method that is based on observing, questioning, creating a hypothesis, testing, etc. Additionally, science is trigger by a natural human curiosity for understanding the world. Due to this, science and the knowledge obtained through it are not exclusive of one historical period but have been developed throughout history.
Indeed, scientific knowledge can be traced back to ancient societies such as Mesopotamia or Egypt and during all centuries and periods including classical antiquity, the middle ages, the modern era, and the post-modern era it expanded through multiple fields including medicine, physics, chemistry or biology. However, the paradigms and ideas have changed over time as the development of more precise technologies sometimes prove previous theories or ideas are not true.

The wind energy does not generate pollutants like the energy generated by conventional fuels like fossil fuels.
What is required for reactants to form bonds?
Answer:
energy input
Explanation:
Chemical reactions are the result of the transformation that takes place in substances (the reactants), where atoms rearrange themselves to their initial state, transforming them into what we call "resultants." Thus, chemical compounds undergo changes generating new molecules. For the reaction to occur it is necessary that there is already an energy input during the handling of the reagents. This energy will be used to rearrange the reagent atoms.

Release of adrenaline by the adrenal glands
Release of cortisol by the adrenal glands
Release of adrenaline by the gonads
Release of cortisol by the gonads
Answer:
Release of adrenaline by the adrenal glands.
Explanation:
Adrenaline hormone also known as epinephrine is an important part of sympathetic nervous system. It is released from adrenal medulla through a sequence of events in a situation of "fight or flight" or we can say in a life threatening situation. This hormone causes our muscles to perform vigorous activities so that body could respond accordingly. Chemically adrenaline hormone is synthesized by using "tyrosine" as a precursor which after a series of enzymatic actions gets converted into L-dopa and then dopamine then nor-adrenaline and finally into adrenaline.
