Which of the following statements regarding human cells are true? Check all that apply.
lana66690 [7]

Answer:

  • Human growth and functioning can be explained by the functioning of the cells.
  • Cells are the fundamental units of humans.
  • The functioning of the cells in the body determine human health.

Explanation:

The cell is the basic unit of life. Therefore the biochemical activities of the cell at a micro-level will definitely influence overall physiology at the macro level of an organism. For example, the production of Thyroid hormone at the molecular level by the cells in the thyroid glands will influence the metabolisms of all cells in a human being and therefore affect the organism’s overall growth and development.

Research how to compost material, which materials are biodegradable, and which are not. A good place to start your research is t
pshichka [43]

Composting is a technique that allows biodegradable materials of urban, domestic and industrial origin to be degraded to form humus, a type of soil that is very fertile and extremely rich in micronutrients.

These biodegradable materials are materials of organic origin, such as food scraps, fruit peels, pieces of vegetables, among others. As the domestic environment generates a large amount of organic waste, composting in this environment is very favorable, and it can generate a very rich soil to be used in the garden, in vegetables, among other places.

Composting occurs when organic waste is stored for a certain period of time. At that time, decomposing fungi and bacteria degrade all organic matter forming the humus. It is necessary that during the time of storage of this garbage, it must be stirred in a certain period of time, to avoid the overheating of the organic matter, causing fires.

Composting can be either vermicomposting or dry composting. In vermicompostings, earthworms are added to the stored garbage, which help fungi and bacteria in the decomposition of this garbage, making the process faster. In dry composting, on the other hand, microorganisms work without any help.

It is important to note that only organic materials can be used in this process, because bacterial and earthworm fungi do not use substances present in non-organism material in their metabolism, and these materials cannot degrade.

As advantages of composting, we can say that it reduces the amount of waste, does not cause the release of methane into the atmosphere (it only releases carbon dioxide, water and biomass) and allows the created humus to be added to the soil, reducing erosion and improving aeration from soil.

As disadvantages we can say that because it is a material that is decomposing, composting can attract flies and other insects and animals that can pass diseases or cause discomfort to people. In addition, it is necessary for someone to be aware of the temperature and humidity of the compost, to avoid fires and other problems.

To start composting in your home, you must first separate organic and non-organic waste. In addition, you will have to buy a compost bin to store the garbage correctly and research a lot about it, to learn the safety methods that should be used and the stages of decomposition of this material.
