Answer:
Lead is toxic mostly because during biochemical reactions it tries to substitute certain metals. hence while doing this, It disrupts with the proteins that control blood pressure, the production of heme and the formation of sperm. Through reactions that propagate electrical signals in the brain, lead often consumes calcium, which reduces the capacity to think and retrieve information.

Answer:
secondary succession
Explanation:

Answer:
11km
Explanation:
The total distance travelled is the sum of the distance as follows:
- from home to friend's house
- from friend's house back home
- from home to the mall
According to this question;
* I walked from my house to my friend's place and covered 0.5km
* I walked back from my friend's house home in the same 0.5km
* I drove to the mall from my house and covered a distance of 10km
Hence, the total distance covered is 0.5 + 0.5 + 10
= 11km
D) Active transport. In this process, dissolved molecules move across plasma membrane from a lower to higher concentration. Because they move against the concentration gradient, an energy from the cell is required.
Answer:
In my personal opinion, I think this is possible because your body already knows the cell. It is already familiar with it.
