Plant cell walls consist mainly of

Correct Answer: < 5 deg Celcius

Explanation:

To reduce the risk of bacterial contamination, many foods must be stored in the refrigerator and thus kept below 5 degrees Celsius. These foods are often classified as ?high-risk foods? and include ? meat, poultry, dairy, seafood, eggs, smallgoods and cooked rice and pasta. This also refers to ready-to-eat foods that have high-risk foods as ingredients and include ? casseroles, quiche, pasta salad, pizza, sandwiches and many cakes.

 

By keeping these high-risk foods under 5 degrees Celsius it stops them from entering the ?danger-zone? ? temperatures between 5 degrees Celsius and 60 degrees Celsius. The danger-zone is the temperature zone which provides bacteria with the perfect environment to rapidly grow and multiply to numbers that cause food poisoning.

 

Correct Answer: Plants are photosynthetic autotrophs, which means that they are able to produce their own food through the process called photosynthesis In photosynthesis, plants use light, water, and carbon dioxide to create glucose, which they convert to cellulose and use to make new cells Hence, that is why, Plants are called photosynthetic autotrophs

Correct Answer: In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy Carbon : coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2

Correct Answer: Methane

Explanation:

Methane is the main component of biogas and natural gas.

Correct Answer: Brain death

Correct Answer: After you eat, insulin stimulates the lowering of blood sugar levels.

Explanation:

Eating raises blood sugar levels, insulin stimulates the lowering of blood sugar level. In this example the response to the stimulus (increased blood sugar levels) opposes that stimulus (by lowering blood sugar levels).

Correct Answer: the extent to which a given food raises blood glucose and insulin levels

Explanation:

The glycemic index or glycaemic index is a number associated with the carbohydrates in a particular type of food that indicates the effect of these carbohydrates on a person's blood glucose (also called blood sugar) level. A value of 100 represents the standard, an equivalent amount of pure glucose.

 

The GI represents the rise in a person's blood sugar level two hours after consumption of the food.

Correct Answer: Cartography

Explanation:

The art and science of map making is called Cartography.

Correct Answer: Photosynthesis

Explanation:

Photosynthesis process removes carbon dioxide from the atmosphere. Green plants remove carbon dioxide from the atmosphere by photosynthesis. 

The level of carbon dioxide in the atmosphere is maintained by several processes, including photosynthesis, respiration and combustion. 

Correct Answer: nutrients and other life-sustaining molecules are in limited supply and must be continually recycled

Explanation:

Biogeochemical cycles are crucial to ecosystem function because ::

 

1. Chemical elements are available in only limited amounts and must be recycled.

2. Nutrients and other life-sustaining molecules are in limited supply and must be continually recycled.
