Active transport of fluid and electrolytes across the cellular membrane typically requires?
Active transport requires energy in the form of ATP conversion, carrier proteins, or pumps in order to move ions against the concentration gradient.
Active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.
Active or passive transport?Passive transport is a great strategy for moving molecules into or out of the cell. It's cheap, easy, and all the cells have to do is stop and let the molecules diffuse.
In active transport, as opposed to passive transport, the cell expends energy (eg, in the form of ATP) to move a substance against its concentration gradient.
With this information, we can conclude that the active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.

The carbon cycle is a cycle among the carbon reservoirs. What is a carbon reservoir and what are at least 3 examples?
Answer:
The reservoirs are the atmosphere, the terrestrial biosphere (which usually includes freshwater systems and non-living organic material, such as soil carbon), the oceans (which includes dissolved inorganic carbon and living and non-living marine biota), and the sediments (which includes fossil fuels).

An organism that breaks down hydrogen sulfide as a source of energy and gets its
carbon from carbon dioxide would be classified as a:
a. Chemoautotroph
b. Photoheteroptroph
c. Chemoheterotroph
d. Photoautotroph
Photoheterotrophs. A heterotroph is an organism that depends on organic matter already produced by other organisms for its nourishment. Photoheterotrophs obtain their energy from sunlight and carbon from organic material and not carbon dioxide.

Cocaine, amphetamine, and MDMA are all central nervous ________ that agonize dopamine neurotransmission.
Cocaine, amphetamine, and MDMA are all central nervous stimulants that agonize dopamine neurotransmission.
How do these stimulants affect the central nervous system?Cocaine, amphetamines, caffeine, nicotine, and MDMA (ecstasy) all cause the nervous system to become more active.
In biology and medicine, chemicals that hasten the transmission of messages between nerve cells are referred to as stimulant drugs. These chemicals include caffeine, nicotine, cocaine, and ecstasy.
Dopamine accumulates excessively between nerve cells as a result of cocaine's ability to stop it from being recycled. The high from cocaine is eventually brought on by this dopamine overflow, which interferes with regular brain activity.
Therefore, stimulant medicines have the ability to speed up the rate at which messages are transferred inside the nervous system.

A doctor sees a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease.
Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?
Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.Learn more in:

How does anesthesia work?
Which would conserve more energy if all humans ate only vegetables or ate only meat
Answer:
There would be more conservation of energy if human beings it only meat.
Explanation:
this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

EXPLAIN How have advancements in computer technology most directly influenced our
knowledge of wildlife and the ecosystems in which they live?
Advancements in computer technology most directly influenced knowledge of wildlife and ecosystems by spreading information about them, about their role in ecosystems, their importance, etc.
What is ecosystem and wild life?
Ecosystems consist of both living organism and non-living substances. Examples of ecosystems are the grassland ecosystem, the ocean ecosystem, the desert ecosystem, etc. In a grassland ecosystem, all organisms, such as plants, animals, and bacteria, work together in coordination. Different ecosystems have different wild lives . Example: In a forest ecosystem, there are tigers, elephants, lions, donkeys, etc.
They are affected by different human-made activities as well as by natural calamities such as earthquakes. The concerns about the changing ecosystem and its impact on wild life, such as the impact of climate change on them and global warming, are highlighted due to the advancements in computer technology. Activists and the general public spread awareness about them.
Hence, in this way, the advancements in computer technology help spread awareness among people about wildlife and the ecosystems .

Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).

Which of the following evidence supports the theory of plate tectonics?
The age of rocks and mountains on the edge of neighboring continents varies.
Fossils from the same species are found on only one continent.
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
Grooves created from glacier movement travel in opposite directions on each continent.
The characteristics of the tectonic plates allows to find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this, hot magna that can rise through the cracks and separate these plates.
In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.
Another proof is that other similar animals are on continents separated by great distances.
Let's analyze the different claims:
a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.
b. False. Fossils of the same spice are found on several continents.
c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.
d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.
In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
