Oxygen and glucose are produced during photosynthesis and are used as the precursors for cellular respiration.
Carbon dioxide, water, and ATP are produced during cellular respiration, and these substances along with sunlight are the precursors for photosynthesis. Carbon dioxide and water are the reactants of photosynthesis. The method through which plants produce their own nourishment is called photosynthesis. Carbon dioxide and water are the reactants in photosynthesis.
While respiration produces ATP by breaking down organic molecules, photosynthesis uses light energy to create ATP, which is then used to create organic molecules. Both involve chemiosmosis and an electron transport pathway for the synthesis of ATP.

When there is greater response from a postsynaptic neuron because of the release of neuromodulators it is ____________ . This may result from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons. When there is less response from a postsynaptic neuron because of the release of neuromodulators, it is called ____________ . This results from either ____________ amount of neurotransmitter in the synaptic cleft or ____________ number of receptors on postsynaptic neurons.
Answer:
Neurotransmitters; neuromodulators; facilitation; an increased; an increased; inhibition; a decreased; a decreased.
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

when humans consume ethanol, the first step in its metabolism is:
When humans consume ethanol, the first step in its metabolism is the conversion of ethanol to acetaldehyde by an enzyme called alcohol dehydrogenase (ADH).
ADH is found in the liver and is responsible for catalyzing the oxidation of ethanol to acetaldehyde, which is a toxic and reactive compound. Acetaldehyde is then rapidly converted to acetate by the enzyme acetaldehyde dehydrogenase (ALDH), which is also found in the liver.
Acetate is a less toxic compound that can be further metabolized into carbon dioxide and water, which can be eliminated from the body through exhalation and urine.
The process of metabolizing ethanol into acetate generates energy and also produces reactive oxygen species, which can contribute to oxidative stress and damage in the body. Prolonged and excessive alcohol consumption can lead to liver damage, as well as other negative health consequences.

Answer:
A positive feedback causes to continue of negative feedback cause it to stop or start
Explanation:
A positive feedback occurs to help increase the output or increase the changes. While a negative feedback occurs to decrease or reduce the output or decrease the change. A positive feedback amplifies the results of any reaction to make the reaction more quickly and the negative feedback results in a reaction to reduce the system to its original state or stable state. Thus a positive feedback occurs to continue while negative feedback causes it to stop or to start.
how does plant makes their own food
What is it?
Photosynthesis is the process in which plants make food for themselves by a constant growth cycle. Photosynthesis benefits us and the plant. Photosynthesis helps us by providing the release of oxygen into the air, and the plant gets food. Plants are autotrophs, I will explain what those are in a moment.
What are autotrophs?
Autotrophs are organisms able to create their own food for themselves through a process or cycle. Autotrophs are interesting creatures. They can create this food for themselves out of the substances within our environment, such as carbon dioxide.
Process of photosynthesis
Plants absorb CO2 and H2O from the soil and air. The water inside the plant cell is oxidized, which causes it to lose electrons. Since the CO2 is reduced, this water, at the same time, gains electrons. The water transforms into oxygen, which the plant releases during this process, and the CO2 turns into glucose, which is major for the energy needed across the plant cell.

A cart with mass 370 g moving on a frictionless linear air track at an initial speed of 1.8 m/s undergoes an elastic collision with an initially stationary cart of unknown mass. After the collision, the first cart continues in its original direction at 1.0 m/s. (a) What is the mass of the second cart
The mass of the second cart is 0.666 kg. In this scenario, we may apply this technique to calculate the second cart's mass.
Let m₁ represent the first cart's mass and m₂ represent the second cart's mass. Let v₁ and v₂ be their initial speeds, and v₁ be the first cart's ultimate speed following the impact.
With the help of momentum conservation, we have:
M₁V₁ and M₂V₂ = M₁V₁ and M₂V₂
Since the second cart is originally at rest, we know that v₁ = 1.8 m/s, v₁= 1.0 m/s, and v₂ = 0 m/s. When we enter these values into the formula above, we obtain:
m₁(1.8) = m₁(1.0) + m₂(0)
When we simplify this equation, we obtain:
(m₁ * v₁) / (v₂) = m₂
With the values from the problem substituted, we obtain:
m₂ = (0.666 kg * 0.37 kg * 1.8 m/s)
Consequently, the second cart has a mass of 0.666 kg.

b. A scientist discovers a new living organism with cells but no tissues.
c. A scientist discovers a new living organism that has no cells.
d. A scientist discovers a new living organism that has cells that work separately.
Answer:
c. A scientist discovers a new living organism that has no cells.
Explanation:
The cell theory is a widely accepted and globally recognized theory of living things. It was proposed in the 1830's by the collective effort of three scientists namely: Mathias Schleiden, Theodor Schwann and Rudolph Virchow. The cell theory is made up of three components as follows:
- All living things are made up of one or more cells.
- The cell is the basic and fundamental unit of life.
- All living cells comes from pre-existing cells.
According to this question, a new evidence that can possibly create a change in the cell theory is if a SCIENTIST DISCOVERS A NEW LIVING ORGANISM THAT HAS NO CELLS because all living organisms have been said to be made up of cells in the cell theory.

Under which conditions would on-site inspection be better than off-site at a specialized test lab?
On-site inspection would be better than off-site at a specialized test lab under conditions where real-world environment, immediate feedback, and accessibility are crucial factors. On-site inspections allow for a more accurate assessment of the actual working conditions, minimize disruptions to operations, and facilitate timely communication between the inspectors and the facility's personnel.
There are certain situations where an on-site inspection would be better than an off-site inspection at a specialized test lab. For example, if the equipment being tested is too large or sensitive to transport, it may be more practical to conduct the inspection on-site. Additionally, if the test requires monitoring and adjustment in real-time, an on-site inspection may be necessary to ensure accurate results. On the other hand, if the test can be conducted remotely and the equipment is not too large or sensitive, an off-site inspection at a specialized test lab may be more convenient and cost-effective. Ultimately, the decision to conduct an on-site or off-site inspection will depend on the specific requirements of the test and the capabilities of the testing facility.
