Answer:

C. Carbon Dioxide

Explanation:

In a process called “photosynthesis,” plants use the energy in sunlight to convert CO2 and water to sugar and oxygen. The plants use the sugar for food—food that we use, too, when we eat plants or animals that have eaten plants — and they release the oxygen into the atmosphere.

Jon likes hiking. He observes that whenever he hikes up a hill he breathes heavier than when he is on flat ground. Which 2 state
Alekssandra [29.7K]

Answer:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

Explanation:

-Sensors in the brain detect a lack of oxygen.

-The muscles in his body need more energy and therefore more oxygen.

-The body has too little carbon dioxide to maintain function.

-The body is using carbon dioxide instead of oxygen to make energy.

-Blood pressure has decreased, so less blood is being pumped to the muscles.

<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>

At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.

<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>

The neandertal site in croatia that has produced hominin remains showing the full suite of classic neandertal morphology is:____
AlekseyPX

The neandertal site in Croatia that has produced hominin remains to show the full suite of classic Neandertal morphology is Krapina.

Explain the morphology of Neandertal.

Below 55 degrees North latitude, Neandertals inhabited Western Eurasia. Notably, none have been identified in North Africa despite their presence south of Haifa (Israel), despite their presence.

Paleogenetic evidence suggests they existed in the East, reaching as far as Southern Siberia. This distribution depicts the northern boundary of the eco-geographical range of humans in the Late MP and Early LP.

This had significant ramifications for the Neandertals' biological adaptations, the pattern of terrain occupation, and demography. They were large-bodied hominins with higher energy needs than the majority of modern hunters and gatherers.

All of the isotopic studies that are currently available indicate that their primary source of protein was animal, and the archaeological record paints a picture of effective hunters who concentrated on medium-sized prey.

Hence, the answer is Krapina.

A decrease in susceptibility to a drug after continued use of the drug is known as:
gavmur [86]

Answer:

tachyphylaxis

Explanation:

Addictive or tolerance - unofficial name.

This is accompanied by the addiction of the body to the medicine. The receptors memorize the chemical substances of the drug and when they are reintroduced, they do not react to it. In this case, the medicine is rapidly eliminated from the body as drug is not digested
