Answer:
Insecticide sweet corn
Scientists have genetically modified sweet corn so that it produces a poison which kills harmful insects. This means the farmer no longer needs to fight insects with insecticides. The genetically modified corn is called Bt-corn, because the insect-killing gene in the plant comes from the bacteria Bacillus thuringiensis.
Disadvantages:
This type of genetically modified corn will poison the insects over a longer period than the farmer who would spray the crops once or twice. In this way the insects can become accustomed (or resistant) to the poison. If that happens both crop spraying and the use of genetically modified Bt-corn become ineffective.
A variety of insects are at risk of being killed. It might be predatory insects that eat the harmful ones or, perhaps attractive insects such as butterflies. In the USA, where Bt-corn is used a great deal there is much debate over the harmful effects of Bt-corn on the beautiful Monarch butterfly.

Just about everything we develop has intended and unintended and unexpected consequences.
Answer:
Genetic code refers to the instructions contained in a gene that tell a cell how to make a specific protein. Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.
Explanation:
A cell would not function as much as it would with the Endocytosis and Exocytosis.
Answer:
6 times
Explanation:
The process if cellular respiration is divided into three major phases : Glycolysis, Kreb cycle and ETC (electron transport chain). Starting from Glycolysis, which occurs in cytosol and breaks the simple glucose molecules. It is the first step of the cellular respiration, in which one glucose molecule is broken down into two molecules of 3-carbon pyruvates.
Each of these 3 carbon pyruvate molecules lose a carbon to form acetyl-Co A and enter into Citric acid cycle- the second stage of cellular respiration. For each pyruvate going into citric acid cycle 1 GTP
, 3 NADH
, 1 FADH2, and 2CO2 molecules are formed. The stage is next followed by electron transport chain in which greater amount of energy in the form of ATP is synthesized.
So, we have seen that each glucose molecule starts two preparatory reactions because 2 pyruvate molecules are formed and each enters into separate citric acid cycle. So, if there are 3 molecules of glucose 6 preparatory reactions separately will occur.
Hope it help!
In Biology you study living organisms, so that would include plants and animals.
