B. They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
C. They can be given DNA to allow them to resist harsh conditions.
D. They cannot be modified to be better than organic crops.
The correct option for the modification done that needs to be sprayed with pesticides is option (b) They can be given bacterial DNA to produce a toxin that only works on bugs and other pests.
Here, we deal with the concept of genetically engineered crops, also called "genetically modified organisms" i.e., GMOs. GMOs approach the specific genes from bacteria of other organisms that produce the required toxins that are harmful only to pests that are inserted into the DNA of crops.
GMOs are examined by crops like Bt cotton or Bt corn. They are genetically modified genes from the bacterium Bacillus thuringiensis (Bt), which are produced by the toxic proteins of certain insects. The use of genetically modified organisms is a complex issue related to the potential health effects, environmental impact, regulatory oversight, and many more.
To learn more about the 'pesticides harmful for crops' are
B. Plant Cells Only
C.prokaryotic cells only.
D.all eukaryotic cells.
Unlike photosynthesis, cellular respiration occurs in all the eukaryotic cells. Thus, the correct option is D.
Cellular respiration is the process by which the biological fuels such as carbohydrates (glucose sugar) are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy-rich compounds, to drive the bulk production of ATP molecule. This process occurs in all types of eukaryotic cells including plant cells and animal cells.
Photosynthesis is the process of formation of food in the form of carbohydrate (glucose) in the presence of sunlight and carbon dioxide in the chloroplast of plant cell and organisms which contain a chloroplast.
Therefore, the correct option is D.

Although at first it may seem like an antigen, it's a pathogen.
Answer:
pathogen
Explanation:
Answer:
C. Reticulated
Explanation:
In reticulated venation there is a central thick vein in the leaf and from there other little veins that form a net flow to the different parts of the leaf, that is called REticulated venation, it often happens that the central vein is located in the middle of the leaf and are easily spotted because that central vein creates a leaf that is two very similar halfs.
Answer:
The answer is sunlight
