There are four primary categories of energy expenditure. Of the following, which one represents the majority of total energy use by the body?.
There are four primary categories of energy expenditure, and basal metabolism is one representing the majority of total energy use by the body.
What is Basal Metabolism
Basal Metabolism is the minimum energy required to sustain life.
Basal metabolism is the number of calories needed by the body to carry out its basic functions such as breathing, moving the heart rate, brain function and various activities in the body over time.
Even when eating, absorbing to processing food also requires calories.
In essence, all the small parts in the body are like engines that burn gasoline as they work. Never stop during life, even keep working while sleeping. Just like a car, where when the car starts, gasoline is still used.
The more we move or activity, the more gasoline is burned. A simple example, the lungs burn energy when breathing. They will work harder when climbing stairs than when sitting. That is, whatever we do above the Basal Metabolism level, the more gasoline (energy) we use. The more active we are in daily life, the more our metabolism will increase.
Another way to increase metabolism is to exercise regularly. Exercise can not only increase metabolism, but also can burn energy in cells faster.

Photosynthesis is a process during which plants synthesise sugar using chlorophyll molecule and further this chlorophyll molecule along with mitochondria uses the sugar and convert it to energy molecule ATP.
1. The Calvin cycle receives ATP and NADPH from the light reactions and gives back ADP, Pi, and NADP+ to the light processes.
2. A magnesium ion stabilises the chlorophyll molecule at the core of the porphyrin ring and sends electrons down an electron transport chain to power the photosynthetic reaction.
3. water
4. Light hits PS2 and pigment molecule absorbs energy and gets excited to release electron. The electron is taken by the primary electron acceptor. Enzyme separates water into H+ (the two electrons) and O-, and supplies p680 with the electrons (strong oxidising agent). H+ is discharged into the thylakoid space, and oxygen from a split water molecule joins with another oxygen to produce O2.Photoexcited electrons travel from PS2 to PS1 through ETC. In PS1, electrons move to a lower energy level, supplying ATP with energy. As they descend, their energy pumps H+ into the chemiosis-related thylakoid luman. The electron in PS1 reaction complex P700 is excited by light energy that has been transferred there. After the electron passes through a second ETC, NADP+ reductase adds an electron, converting NADP+ into NADPH.
5. ATP synthase generates ATP by facilitating the flow of electrons back into the stroma.
6. Instead of absorbing green light, chlorophyll absorbs red and blue light. green light reflects
7. When the electrons from PS1 go to the ETC and produce ATP before returning, it is considered cyclic (no water required). Noncyclic occurs when NADP+ is converted to NADPH by NADP-reductase using electrons transferred from PS1 to PS2.

Sex hormones are steroid hormones that interact with vertebrate steroid hormone receptors. They are also known as sex steroids, gonadocorticoids, and gonadal steroids. Androgens, estrogens, and progestogens are among the sex hormones . Their effects are mediated by both fast nongenomic mechanisms through membrane-associated receptors and signaling cascades as well as by slow genomic mechanisms through nuclear receptors. Although they serve significant sex-related roles, the polypeptide hormones luteinizing hormone, follicle-stimulating hormone, and gonadotropin-releasing hormone—all of which are connected to the gonadotropin axis—are typically not regarded as sex hormones.

What is climate change?
Long-term altercations in weather and temperature patterns are referred to as climate change. These changes might occur naturally, for instance through variations in the solar cycle. But since the 1800s, burning fossil fuels like coal, oil, and gas has been the primary cause of climate change, which is mostly attributable to human activity.By trapping the sun's heat and increasing the temperatures, greenhouse gas emissions mostly produced by burning fossil fuels behave as a blanket over the planet.Methane and carbon dioxide are two examples of the greenhouse gases that are contributing to climate change. These result from using fuels like gasoline or coal to heat buildings, respectively. Carbon dioxide can also be released during logging and clearing land. Methane emissions are primarily produced by landfills for trash.According to the Intergovernmental Panel on Climate Change (IPCC), global warming is responsible for a number of extreme impact events, making mountain ecosystems particularly vulnerable to climate change.
As glaciers continue to recede, less water is available, which causes more erosion and landslides in mountainous regions. High mountains are considered "particularly temperature-sensitive locations," and there is data to suggest that temperatures are increasing more quickly at higher elevations.

One of the three primary rock types, along with sedimentary and metamorphic rocks, is igneous rock, also known as magmatic rock.The cooling and solidification of magma or lava results in the formation of igneous rock.The planet's crust or mantle may partially melt existing materials to produce the magma. A rise in temperature, a fall in pressure, or a change in composition are typically one or more of three processes that lead to melting. Extrusive rocks form on the surface or intrusive rocks form below the surface as a result of solidification into rock.Intrusive refers to igneous rocks that have solidified and cooled below the surface. Rocks that are intrusive to a pluton are also referred to be plutonic. A pluton is an intrusive rock body made of igneous material that has cooled within the crust. The cooling of magma inside the Earth happens gradually. Large crystals can form because of slow cooling, which is why intrusive igneous rocks can be seen to include crystals.
