the element is potassium

Answer:

I believe it should be structure.

Explanation:

Answer:

It is super important

Explanation:

It is critically important that one must know how and what your body needs before introducing new things or removing old things. For eg. people tend to go on keto diets (high fats). But, one must know that our brain neurons require very high energy and need constant sugar. Therefore, if you intake very low sugar in keto diet, you might actually harm yourself more than benefit.

Answer:

DNA repair genes are involved in fixing damaged DNA. Cells with mutations in these genes tend to develop additional mutations in other genes and changes in their chromosomes, such as duplications and deletions of chromosome parts. Together, these mutations may cause the cells to become cancerous.

Explanation:

Bacteria can be considered as a chain between animals and plants because it give benefits both plant and animal.

Bacteria has unique features that can benefits both plant and animal. Bacteria like Rhizobium make soil fertile for plants whereas Lactobacillus bacteria help to convert milk into curd.

Answer:

science is the use of technology and momentum is conserved in school

Answer:

The most closely related are amphibians and reptiles.

The least related are amphibians and mammals

Explanation:

Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related

Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

Carbon dioxide (CO2) is the most significant of the greenhouse gases. Volcanic outgassing, organic matter burning and natural decay, and aerobic (oxygen-using) organisms' respiration are all natural sources of atmospheric CO2. On average, these sources are counterbalanced by a collection of physical, chemical, or biological processes known as "sinks," which remove CO2 from the atmosphere. Terrestrial flora, which absorbs CO2 during the photosynthesis process, is a significant natural sink.

CO2 levels in the air and probable health issues are as follows: The average outdoor air level is 400 parts per million. 400–1,000 ppm: typical concentration found in inhabited spaces with adequate ventilation. Drowsiness and poor air quality are linked to levels of 1,000–2,000 ppm.

Human activities, on the other hand, increase atmospheric CO2 levels primarily through the combustion of fossil fuels—primarily oil and coal, and secondarily natural gas—for transportation, heating, and electrical power generation, as well as the creation of cement. Forest fires and land clearing are two further examples of anthropogenic origins.

Anthropogenic emissions currently account for around 7 gigatons (7 billion tons) of carbon released into the atmosphere each year. Anthropogenic CO2 emissions account for about 3% of total CO2 emissions from natural sources, and this magnified carbon burden from human activities far surpasses natural sinks' balancing capacity (by as much as 2–3 gigatons per year).

Sea levels are rising, and the oceans are warming. Droughts that last longer and are more intense endanger crops, wildlife, and freshwater supplies. The richness of life on our world is threatened by climate change, from polar bears in the Arctic to sea turtles off the coast of Africa.

Ways to reduce global warming?

Improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet.

3. Matter is lost on earth but energy is transformed from one form to another. The ultimate source of energy is the sun and then its is transformed from one form to another. The matter is not converted from one form to another form, it gets destroyed as the plant and dies. So, we can say the energy is conserved on earth but the matter gets destroyed.

4. The carbon model is the flow and the movement of the carbon and its compound in the atmosphere. Climate change is the limitation of the carbon model.

A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.

Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall.

Therefore, climate change is the limitation of the carbon model.

Hypothalamus works with the endocrine system and the nervous system. Thus, the correct option is A.

Endocrine system is the hormone-producing glands and organs release hormones directly into the bloodstream, allowing them to travel to tissues and organs throughout the body.

In the brain's, lower center region, The hypothalamus is present. It is a link between the endocrine and neurological systems. Chemicals produced by nerve cells in the hypothalamus regulate the release of hormones generated by the pituitary gland.

The hypothalamus collects data from the brain (such as ambient temperature, light exposure, and feelings) and delivers it to the pituitary gland. This information has an impact on the hormones produced and released by the pituitary gland.
