<h2>Answer:</h2>
Bt corn is a genetically modified organism that contains a gene of bacteria known as Bacillus thuringiensis.
<h3>Explanation:</h3>
- Bt corn is a type of transgenic crop that contains a gene which produces a crystal-like protein which has an insecticidal effect.
- This gene is present in bacteria. This gene is transferred to the plant by the recombinant DNA technology and genetic engineering.
- This bacterium is a soil bacterium which has no side effects on humans.
- Due to use of this technology, the poisonous chemical insecticides are not used in crop production.
Answer:
the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Explanation:
Nucleus is the main component of the cell and carries out the vital processes of the cell.
- For learning about its structure, a nucleus diagram is quite helpful. Important components of its structure include.
- One feature of the nucleus that distinguishes eukaryotic cells from prokaryotic ones is the nuclear membrane.
- Additionally, it has a double-layer structure. It also has phospholipids in it.
- The nuclear envelope, nucleoplasm, or nucleus sap, nuclear matrix, chromatin, and nucleolus are some of the several structures that make up the nucleus.
- The nuclear membrane, also referred to as the nuclear envelope, creates an envelope-like structure surrounding the nuclear contents.

Without predators in an ecosystem, the ecosystem would be dominated by consumers. more consumers in an ecosystem would lead to eating more producers. predators keep an ecosystem in check, to make sure that there isn't overpopulation. hope this helps!
