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.

Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

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.

Bacteria for these three.
Morphology and arrangement?
Answer:
There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.

Note on chemical communication in insects in general
Answer:
Chemical communication plays an important part in the lives of insects, and particularly in lives of those that live in groups or social organizations. Aggregation pheromones are designed to bring individuals together into groups which may be temporary in sub-social insects, or permanent in social insects.

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

A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal?
A. the hydrolysis of IP3
B. the hydrolysis of GTP
C. the hydrolysis of PIP2
D. the hydrolysis of the hormone
Answer: The answer is A
Explanation: Took the test lol
The quickest halt to the signal transduction process after IP3 production occurs through the hydrolysis of IP3 itself, as option A.
The hydrolysis of IP3 results in the quickest termination of the signal transduction pathway among the available alternatives. A series of actions are triggered by IP3, which causes the release of calcium ions from intracellular reserves. IP3 is hydrolyzed by phosphatases, which halts the calcium release and prevents protracted signaling.
Even while the hydrolysis of GTP and PIP2 is a necessary step in the cessation of G protein-coupled receptor signaling, it happens later and does not have the same rapid effects as IP3 hydrolysis. The hormone's own breakdown is not a known mechanism for halting signal transmission.

Answer:
It will take 1.85 hours to walk 12 km north.
Answer:
Explanation:
v=[tex]\frac{d}{t}[/tex]
and the d here is the distance which is equal 12 km
the time is still unknown
and we know the velocity which is 6.5 km/h
and according to the triangle of the velocity "search that up "
t =[tex]\frac{d}{v}[/tex]= [tex]\frac{12}{6.5}[/tex]≈1.8 hours

The Sun is the primary source of energy that drives all the biogeochemical cycles on Earth. Which statement best describes how the Sun’s energy powers the water cycle?
A.
Plants require energy from the Sun to perform photosynthesis.
B.
The Sun's heat reflects off ice sheets near the polar caps, reducing the overall temperature of Earth.
C.
Heat from the Sun drives evaporation, turning water on Earth's surface into water vapor.
D.
Energy from the Sun provides the warmth necessary for cold-blooded animals to survive.
Answer: A
Explanation:
Answer:
C) Heat from the Sun drives evaporation, turning water on Earth's surface into water vapor.
Explanation:
The question is discussing water cycle, so the answer must be something to do with water. Option A talks about to photosynthesis in plants, which is not directly related to the water cycle. Option B discusses earth temperature, which is again not related to the water cycle. Finally, option D talks about the living requirements for cold blooded, again not related to water cycle. That leaves option C.

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:

What happens when the thin filament in a muscle fiber slides over the thick filaments?
Answer:
As the thin filaments slide inward, structures called Z-discs come toward each other and the sarcomere shortens but the lengths of thick and thin filaments do not change. The sliding of the filaments and shortening of the sarcomere cause shortening of the whole muscle fiber and ultimately the entire muscle.
Answer:
Sliding of the filaments and shortening

Answer:
The cell theory states that all living beings are made of cells. There is a debate as to whether or not viruses should be considered to be alive. The debate results from the fact that viruses cannot reproduce on their own. They must invade a host cell and utilize the host’s genetic material in order to reproduce. Viruses are not true cells. They lack the most important part of the cell, the protoplasm. Hence, the cell theory is not applicable to viruses. Hence, the answer is C.
