The hypothesis would be: Consumption of a single apple every day will reduce the number of visits to the doctor.

The hypothesis is a proposed explanation that is a starting point for further investigations. So, in this case, we assume that eating one apple a day will keep us healthy, without the need for the doctor.

Answer:

The correct answer is would be - Eating a single apple every day changes the frequency or number of visiting doctors.

What are two reasons bees are important beyond making honey
zhenek [66]

Answer:

Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning.

The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes. Bees also pollinate around 80% of wildflowers in Europe, so our countryside would be far less interesting and beautiful without them.

As our global population rises; so does our appetite for protein. Our meat consumption habits take a serious toll on the environ
Volgvan
<h3>Meat consumption and environment</h3>

Explanation:

Increase in population rises protein demand. Many people meet their dietary protein requirements mainly from animal sources by consumption of meat and meat products like meat, eggs, and processed meat products.

Increased meat consumption leads to increase in global warming. Increased meat consumption raises the demand for meat and animal farming like cattle, poultry and fish farming.

Farm animals release methane through their waste into the environment. Methane is one of the most potential greenhouse gases that cause global warming.  

Animal farming practices requires a lot of water and hence depletes natural water sources. Moreover, the effluent drainage from farmlands pollutes the land as well as natural ground water sources with methane and other pollutants including pathogens and renders the natural sources unusable.

Further, farm animals like cows and goats grazes farmlands and destroys the green cover which helps in carbon sequestration.

1.What process can cause rock to move deep underground?
atroni [7]

Answer:

1.) "Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes move rocks and sediment to new locations."

2.) "Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away."

Explanation:

Hope this helps :))
