Give them a prescription medication, then continue training session D. Give them Advil, then continue training session
Answer:
A .recommended they drink water then stop training session
Explanation:
Because the trainer can't just give out prescription medication. They don't know if the person has allergies and it can make the clients headache worse.
A. Recommend they drink water, then stop the training session
First thing first, drug abuse is not an option. Drug abuse includes self medication or taking drugs not prescribed by a medical practitioner. As a fitness trainer, ones job is not to prescribe drugs.
According to this question, if a client is experiencing headaches during a training session, the best alternative for the trainer is to recommend taking water to calm the client down, then put an hold to the training. The trainer is not qualified to prescribe any drug whatsoever.
Therefore, the trainer should recommend that a client with headache drink water, then stop the training session.

Answer: A
Explanation:
Answer:
b
Explanation:
you can already get rid of d and c because you know that it has something to do with combining the 2 alleles. Incomplete dominance is when the 2 colors blend together to make another color, like a red and white flowers offspring is pink. codominance is when both alleles are shown, just like the black spots on the chicken. your answer is b!!

As the level of Carbon Dioxide in the atmosphere increases, how will (is) primary productivity impacted? How does this impact populations of primary consumers?
Answer:
Rising atmospheric carbon dioxide (CO2) and nitrogen (N) deposition increase directly the resource availability to plants, and can increase plant growth and net primary productivity (NPP; Norby et al., 2005).
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.
Explanation:
Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.
What do you mean by Net primary productivity (NPP)?Net primary productivity may be defined as the amount of matter accumulated by plants per unit area in a given time.
Primary productivity depends on photosynthesis, where carbon dioxide gets converted to energy. If the level of Carbon Dioxide in the atmosphere increases, the photosynthesis rate increases, and finally the primary productivity increases.
Therefore, Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.

what ia arumen in ruminant animals
Answer:
Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre
The rumen. The rumen (on the left side of the animal) is the largest stomach compartment and consists of several sacs. It can hold 25 gallons or more of material depending on the size of the cow. Because of its size, the rumen acts as a storage or holding vat for feed.
According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food select all that apply
Answer:
It provides ATP.
Explanation:
It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.

Explanation:
Hard corals have a symbiotic relationship with species of microalgae that give the corals their color and provide up to 95% of the corals' energy needs by photosynthesis. Corals get the rest of their food by consuming plankton. The microalgae are damaged by changes in water temperature 2-3C lasting five weeks or more, causing a phenomenon called coral bleaching. What will most likely be the result of increased global temperature on the diversity of hard coral species?
Question 1 options:
The hard corals will make all of their own food.
The rate of photosynthesis in hard corals will increase.
The number of different hard coral species will decrease.
The hard corals will migrate to warmer waters.
Answer:
The hard corals will make all of their own food
Explanation:
your welcome...
The most likely result with increased global temperature would be ; ( A )
The hard corals will make their own food
Given that the relationship between the corals and the microalgae is symbiotic and not parasitic therefore when the microalgae are damaged the hard corals will most likely look for an alternative food source in order to continue surviving since they do not rely 100% on the plankton for their food. which is The hard corals will be able to make their own food by capturing preys like critters.
Hence we can conclude that the most likely result with increased global temperature would be The hard corals will make their own food
