The answer is “d” (1,000 kcal). As the trophic level increases energy is decreases by 10 times that of the previous level. If a system has 10,000 kcal, then the primary consumer have 10 times less (10,000/10) which is 1,000 kcal. The secondary consumers have 100 kcal and the tertiary have 10 kcal. Only 10% of the energy at each trophic level goes on to the next.
Answer:
Nucleic acids as the hereditary material
Explanation:
The nucleic acids are deoxyribonucleic acids DNA and ribonucleic acids RNA. DNA is an hereditary material that carry information and it is found both in eukaryotic cells and prokaryotic cells. It is found in the nucleus of eukaryotic cells but it is not enclosed in prokaryotic cells.
The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.
The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.
However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.
This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.
For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.
Answer:
Fight or flight response.
Explanation:
Fight or flight response is also known as hyper arousal response. This response is mainly generated in case of attack and harmful event.
Jade hears a rattle sound and sees a rattle snake as she turns turns around, this is a type of harmful event or fear for Jake. This condition causes the dilation of pupil, sweat and heart pounds in Jade's body. The fight and flight response has been generated in Jade's.
