Answer:
A cell membrane is made of two layers.
The cell membrane is composed by a phospholipid bilayer where the interior side is hydrophobic and non-polar, while the outside is hydrophilic and polar
Pores and proteins in the cell membrane allow passage through it.
The pores and proteins in the cell membrane have several functions such as, for example, cell signaling (proteins) and selective transport (pores)
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
Answer:
it means They have been tampered with by chemicals steroids its science that makes foods bigger and tastes better.
Explanation:
they take the things that make the food and put all types of things in them to make then tastes better like apples they modify those to make them bigger and juicier.
Answer:
According to the Cornwall Alliance, Earth is which of the following? The resilient creation of God’s wise design
Explanation:
Answer:
Explanation:
the advantages include:
disease and drought resistant crops that require fewer environmental resources for them to grow
higher yields harvested as the crops are not attacked by pests resulting in humans receiving more food as well as generating more money from the trading of their crops
increased supply of food at a cheaper life and the crops could have a longer shelf life
crops bound to be healthy as they ae not constantly treated by pesticides that could harm people
reduce the use of pesticides that might be a great move for the betterment of the food supply
they reduce the use of toxins that could harm the environment as well as the animals and people
disadvantages
unexpected or harmful genetic changes that could result in humans health being threatened
the process of genetically modifying the crops is quite expensive
due to the plants becoming pest resistant the pests are bound to have no food hence could die leading to some helpful pests such as beetles or ladybugs that actually benefit the environment going extinct
the production of genetically modified crops results in the disruption of biodiversity as you are favouring one specific organism hence resulting in the disruption of the natural gene flow
the crops are modified hence biotech foods may be a threat to the human health
