The option C, which is, Inactive people use more energy so they should consume fewer calories is not true about energy balance.
Energy balance refers to the relationship between the energy in and energy out. Energy balance is affected by the amount of exercise one gets and their dietary habits. Stored body fat will increase if calorie intake is greater than the energy used.
Stored body fat will increase if calorie intake is greater than the energy used. Energy balance is the balance between the number of calories consumed and the amount of energy used.
The correct answer I think is D. The nucleus
Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.22: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.
Answer:
Cell level organization
Explanation:
Organisms are composed of different level of organizations like atomic level, molecular level, cell level, tissue level, organ level, system level after which whole organism if formed.
If we talk about <u>Arachnoidiscus</u> <u>ehrenbergi </u> it is one celled organism belonging to a group of algae. If we talk about human stomach it is an organ made up of several tissues which in-turn are made up of several cells.
So what is common in both?
It is a cell that is common in both, because cell is the basic unit for life of <u>Arachnoidiscus</u> <u>ehrenbergi </u>and a unit of the composition of whole stomach.
Hope it help!
