Answer:
Water moved out of the cells of the houseplant into the extracellular solution because they (plant cells) have a high water potential (Ψ) than the extracellular environment.
Please find the explanation below
Explanation:
In biology, water potential, denoted by Ψ, refers to the ability of water to move freely in a system. Based on this definition, a hypertonic solution (solution with higher solute concentration) will have a low Ψ while a hypotonic solution (solution with low solute concentration) will have a high Ψ.
According to this question, if a houseplant is fertilized too often, it will increase the concentration of solute in the soil (extracellular environment of the plant cells) i.e. the fertilizer will make the extracellular solution HYPERTONIC. Because the cells of the houseplant are hypotonic to the soil solution i.e. now has a high Ψ in comparison with the soil solution, water will move from the cells of the plant to the soil solution (extracellular) via the cell membrane (semi-permeable membrane) in a process called OSMOSIS.
NOTE: Water moves from a solution with high Ψ to a solution with low Ψ. This is what propels the movement of water from the cell with a high water potential to the exterior of the cell with a low water potential (caused by frequent addition of fertilizer). Overall, the houseplant will look WILTED even if the soil is wet.

Griffith found that this combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S strain
Live T strain + Live S strain
Heat-killed R strain + Live S strain
Heat-killed R strain + Live R strain
Answer:
Live R strain + Heat-killed S strain
Explanation:
The R strain, in its live version, was nonvirulent. The ordinarily virulent S strain, when killed by heat and injected into the mice, became nonvirulent. However, when the mice were injected with both the nonvirulent R strain and the heat-killed S strain, the mice died.
Griffith found in his experiment that the following strain combination of Streptococcus pneumoniae strains was highly severe.
Live R strain + Heat-killed S
What was Griffiths experiment?Frederick Griffith performed one of the first tests to demonstrate that cells contain genetic material in 1928.Griffith's experiment used two pneumococcus strains: a deadly virulent strain (S) and a non-virulent strain (N) (R)Griffith infected mice with a non-virulent strain of bacteria (strain R) and found that they survived.Griffith used the pathogenic bacteria (strain S) to infect mice, and the mice died.Griffith infected mice with deadly bacteria (strain R) that had been heat-killed, and the mice survived because the bacterium had been killed.Griffith discovered that mice infected with a mix of heat-killed strain S and live strain R died.
Griffiths deduced from this that the live R cells had been converted into pathogenic S cells.

DNA damage can occur as a result of exposure to chemicals or ultraviolet radiation. What happens during nucleotide excision repair of damaged DNA? A. Enzymes delete an incorrect DNA sequence, pull the gap closed, and join the bases on either side of the gap together B. Enzymes cut out the damaged gene, copy the same gene from the homologous chromosome, and insert the copy C. Enzymes detect an incorrect DNA base pairing in a DNA strand, remove the incorrect base, and insert the correct base. D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.

a series of tubes
an organ for gas exchange
a circulating fluid
a cavity for nutrient and gas exchange
a pump
2. Why do larger animals have closed circulatory systems?
Closed circulatory systems feature a smaller network of blood vessels than open circulatory systems, which allows for more targeted delivery of oxygen and nutrients to cells
Closed circulatory systems do not have chambers in the heart, which lessens complexity in the system and increases efficiency in oxygen and nutrient delivery.
Closed circulatory systems are less complex than open circulatory systems such that oxygen and nutrients are delivered to cells more quickly.
Closed circulatory systems allow for mixing of blood with other bodily fluids, which increases the rate at which oxygen and nutrients are carried to cells.
• Closed circulatory systems deliver oxygen and nutrients to cells and carbon dioxide and waste from cells more efficiently than open circulatory systems.

B.
discrimination
C.
extinction
D.
generalization
Answer:
b
Explanation:
The learning that process occurs when organisms are able to distinguish between various similar stimuli and respond only to certain ones is discrimination. The correct option is B.
What is stimulus?A stimulus is defined as anything that can cause a physical or behavioral change. Stimuli is the plural of stimulus.
External or internal stimuli can be used. Your body's response to medicine is an example of external stimuli. Internal stimuli include changes in vital signs caused by changes in the body.
Stimulus generalization occurs when a similar stimulus to an already-conditioned stimulus begins to elicit the same response as the original stimulus.
Stimulus discrimination occurs when an organism learns to distinguish the CS from other similar stimuli.
The process by which an organism learns to respond differently to similar stimuli is known as stimulus discrimination.
According to classical conditioning, the organism only exhibits the conditioned response in response to the conditioned stimulus.
Thus, the correct option is B.

What is the correct term for microbial action that converts inorganic phosphorous back into organic phosphorus?
The process of _______ refers to the conversion of inorganic phosphorus to organic phosphorus.
Answer:
Mineralization
Explanation:
In biology, mineralization refers to a process where an inorganic substance precipitates in an organic matrix. This may be due to normal biological processes that take place during the life of an organism such as the formation of bones, egg shells, teeth, coral, and other exoskeletons
The process of mineralization is referred to the conversion of inorganic phosphorus to organic phosphorus.
Mineralization is the procedures by which chemicals found in organic matter are decayed or oxidized into forms that plants can use.
The transformation of organic molecules in the soil is driven mainly by its microbiota, which includes fungi and bacteria as well as earthworms.
Mineralization tends to increase the nutrient bioavailability found in decaying organic compounds, most notably nitrogen, phosphorus, and sulfur because they are plentiful.
Carbon mineralization is the transformation of carbon dioxide into a solid mineral, such as carbonate. Whenever these rocks are exposed to carbon dioxide, a chemical reaction occurs.
Thus, the answer is mineralization.

What would happen to the concentrations of Pyruvate, NADH and intermembrane H+ if the ETC stopped working?
Answer:
"Proton decreases" would be the right approach.
Explanation:
The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized. Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates. Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.

Felicia observed that the lettuce plants in her garden had wilted after several days of drought. The
next day, there was a downpour of rain, and the leaves began to swell. What cellular process caused
this effect in the lettuce plants?
Answer:
Due to the chought water was released from the plant which caused the plant to shrink or wilt.
Explanation:
Roots take water from the environment through osmosis. This is the diffusion of water molecules from a less concentrated solution to a more concentrated one. Osmotic process caused this effect in the lettuce plants.
---------------------------------------------------------
Osmosis is the phenomenon that occurs when two dilutions of different concentrations are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute. Hence, water can move from the most diluted side to the less diluted one.
Water goes from the most diluted solution to the cell interior until concentrations are equal on both sides. At this point, the cell and the solution are in dynamic equilibrium.
As water enters, the cell begins to enlarge and becomes bigger-sized. It acquires turgidity.
Under natural conditions, the organism regulates the extracellular fluids to avoid cells swelling until they burst.
In the exposed example, the lettuce plants had lost water due to several days of drought. They were dehydrated.
Immediately after the downpour of rain, the plant cells acted as the more concentrated solution, separated by their membrane with a less concentrated solution.
Water molecules moved toward the most concentrated side, the interior of the cell.
Roots took water from the soil by osmotic process and drove it to the different plant tissues, rehydrating the cells.

Answer:
Explanation:
For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced. Each glucose molecule produces two molecules of acetyl CoA, enough for two cycles.
Answer:
[tex]\boxed {\boxed {\sf 2 \ ATP, 10 \ NADH, \ 2 \ FADH_2, \ 4/6\ CO_2 }}[/tex]
Explanation:
The Krebs Cycle is one part of cellular respiration, the process that makes energy/ATP for an organism.
In glycolysis, pyruvic acid is made. After, the molecules are changed to acetyl-CoA.
In the Krebs Cycle, oxaloacetic acid combined with acetyl-CoA form citric acid. Enzymes cause reactions, the NAD molecule gains a hydrogen ion (becomes NADH), and FAD also gains hydrogen ions (becomes FADH₂).
Energy is released, so some ATP can be made. Carbon atoms are released as carbon dioxide (exhaled as a waste product).
So, the Krebs Cycle actually has more than 2 products.
For every 2 pyruvic acid:
2 ATP: energy10 NADH: electron carriers in the electron transport chain2 FADH₂: also electron carrier4 CO₂ (Krebs Cycle) + 2CO₂ (converting pyruvic acid): waste gasWhere can tactile receptors be found in the human body? (mark ALL answers that are correct)
