Why are scientists concerned about the use of the Bt toxin which is used to kill insects in genetic engineering
Answers
Answer:
The Bt toxin gene is not readily accepted by plants.
Explanation:
just did the lesson xx
The toxin Bt (endotoxin CrylA (b)) Bacillus thuringiensis that is a normal inhabitant of the soil, showed himself as a natural insecticide used by farmers engaged in organic farming. In contrast to the Bt-toxin produced by bacteria, genetic engineers included it pesticide in every cell of the seed, and therefore distributed throughout the adult plant, the products from which then are consumed by man. That's why scientists are concerned that after the use of a BT toxin products people get antibiotic resistance and resistance to bt.

Answer:
Oxbow lake is formed when a bend in a river is cut off to form a lake.
Explanation:
- OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox.
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .
- OPTION B - It is formed when a bend in a river is cut off to form a lake.
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
- OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake.
This statement is also wrong, as a river delta is specified by this statement.
- OPTION D - It is formed when a dam stops the flow of a river and creates a lake.
This statement is also false, since the creation of a reservoir is established by this statement.
FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , the correct option is B.

The answer is 2 raccoons per square meter.
The math is very clear. It can be solved using proportion.
If 20 raccoons live in 10 square meters, how many of them will live in 1 square meter:
20 raccoons : 10 m² = x raccoons : 1 m²
⇒
⇒ x =
⇒ x = 2
So, a population density is 2 raccoons per square meter.

The 3 basic steps of DNA replication are: initiation, elongation and termination.
What is DNA replication?
DNA replication is the process by which cells make copies of their genetic material. The process occurs in three main steps:
Initiation: This step involves the separation of the double helix structure of the DNA molecule, and the unwinding of the two strands at a specific point called the origin of replication.
Elongation: This step involves the building of new strands of DNA, which are complementary to the original strands. This is done by enzymes called DNA polymerases, which add nucleotides to the growing DNA chain. The new strands are created in the 5' to 3' direction, meaning that the polymerase adds nucleotides to the 3' end of the strand.
Termination: Once the entire length of the DNA molecule has been replicated, the replication process is complete. The two new DNA molecules, which are exact copies of the original, are then separated from each other.
