Answer:

Naloxone is an antagonist at opioid receptors and heroin is an agonist at opioid receptors

Explanation:

An agonist is a substance that binds to a receptor and causes a biological reaction. In this case, heroine binds to opioid receptors. An antagonist blocks the reaction from the agonist, impeding the receptor's activation. Agonists and antagonists work for specific receptors, and for an antagonist to block an agonist they must bind to the same receptor, like naloxone does with heroin. Giving an antagonist that binds to one receptor and and agonist that binds to a different one means that the antagonist will have no effect.

You perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gm of ammonium nitrate per lite
svetlana [45]

Answer:

homeostasis.

Explanation:

Homeostasis is the process whereby living systems maintain a stable internal environment despite changes in environmental conditions. Plants, like every other living organisms also perform this process to keep their internal environment in a stable state.

According to the question, some plants were exposed to ammonium nitrate, which serves as a nutrient, and 16 hours of sunlight needed for photosynthesis to take place. The plants exposed to ammonium nitrate and 16 hours sunlight grew taller because they had access to nutrients needed to bring about the process of photosynthesis, which provides the plant with energy source (Glucose).

The uptake of nutrients like ammonium nitrate by the plants is done in order to maintain a homeostatic internal environment. Without nutrients, which is the purpose of the ammonium nitrate, plants cannot grow. Hence, the plants exposed to ammonium nitrate, take it in to keep their internal environment functioning.

In the electron transport system
antoniya [11.8K]

Answer:

A. NADH and FADH2 both donate electrons at the same location.

Explanation:

In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.

These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.

Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.

NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.

The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.

If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.

The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.
