Answer:
D. The energy flow is not dependent on any members of the ecosystem
Explanation:
The energy flow in an ecosystem is not dependent on any member of the ecosystem. It is the flow of energy through the food chain, energy is passed from members in one trophic level to members in another or the next trophic level. The flow of energy in an ecosystem is important because it helps in maintaining balance in ecology.
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.

The urinary system helps to maintain the balance of water and electrolytes in the body, aiding in the body's homeostasis. This is achieved through the filtration of the blood by the kidneys, expelling excess substances and waste products.
The urinary system plays an integral role in our body's homeostasis by maintaining the balance of water and electrolytes (Option B). This is accomplished by filtration of the blood in the kidneys, which remove waste products and excess substances, including water and electrolytes. For instance, if our body has a high level of sodium, the kidneys filter out the excess and excrete it into the urine. Similarly, if there is too much water, it will also be excreted. This delicate balance ensures our cells can function properly in the correct environment.

Answer:
The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later
