The major threat to humans and the most prominent selection pressure are disease organisms that target the immune system.
These organisms impair the body's ability to fight off invasion from pathogens, and there is no "back up immune system" to protect the immune system from attack. An example of a pathogen that attacks the human immune system is the Human Immunodeficiency Virus (HIV).

Phosphorus in rivers can lakes sinks to the bottom and over thousands of years becomes ______ again.
pshichka [43]

Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.

That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.

A circular molecule of DNA contains 1 million base pairs. If the DNA synthesis at a replication fork occurs at a rate of 100,000
lakkis [162]

Answer:

<h2>5 minutes </h2>

Explanation:

1. In bidirectional replication;  there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.  

2. So, by  the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize  500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.
