Answer:Answer: C. it has included practices that lead to pollution of soil and water.

Explanation:

Agriculture is the practice of cultivation of economically valuable crops which are food, fibers and medicinal in origin in order to sustain humans and animal species. To increase the productivity of crops farmers or planters take different measures such as increased use of chemicals such as fertilizers, pesticides and weedicides. These chemicals although prevent the crops from disease causing pathogen, makes nutrients available for plant growth. But they contaminate the soil in which crops are growing and pollute the nearby water sources.

Under which conditions do most types of cells function at optimal levels
Scrat [10]

Explanation:

Cells maintain a constant internal environment; this process called homeostasis, ensures that cells obtain an optimal environment in which they can best function.

The endocrine system involves chemical signalling via the secretion of molecules called hormones into extracellular fluid. They bind to chemical receptors in order to cause specific changes in target cells, these lead to changes in the body's internal environment called homeostasis.

It includes the thyroid, parathyroid, pituitary, pineal and adrenal glands along with other regions. The bone, adipose tissue, heart, pancreas and liver are a few of the regions of the body which show endocrine function. The brain, or control center functions to receive and process the information from the receptor. Effectors receive the control center's command and illicits a response in the form of a feedback loop, that may oppose or enhance the stimulus.

Further Explanation:

During homeostasis the body maintains a constant internal balance in pH, temperature, blood pressure etc. Cells in a multicellular organism become specialized for particular tasks and communicate with one another in order to maintain homeostasis. Within the human body these are known as hormone cascades, where several complex steps occur- the tissues signal to one another with the use of hormones released by the endocrine system. The regulation (increase and decrease) of these secretions is achieved by negative feedback loops, where the release of certain substances during a cascade in turn halts the secretion of hormones at earlier stages.

For example, cells within the human body function at an optimal temperature between 97°F (36.1°C)  and 99°F (37.2°C). This is due to the optimal temperature requirement of the enzymes within the human body, which requires this specific range to obtain activation energy.

arlik [135]

The right answer is B.

The purpose of breathing is to do homeostasis, which means, to take CO2 out and get oxygen to our blood.

Babies live into the wound surrounded by liquid, so they don't need to breathe with their lungs.

All the things they needed to survive are taken from the mother thought the placenta.
