<span>10% rule (efficiency between trophic levels): limits how long an ecosystem's food chain can be
Predator/prey cost benefit analysis (i.e. foraging) -- cost is risk of being eaten or killed along the way, benefit is energy/nourishment obtained: limits distribution of predator v. prey
Immigration/Emigration with other populations and ecosystems

Select all the correct answers.<br> Which two statements are true for the leading strand in DNA?
Ghella [55]

Question: Which two statements are true for the leading strand in DNA?

It is synthesized toward the replication fork.

It is synthesized in the 3′ to 5′ direction.

It is synthesized away from the replication fork.

It is synthesized in the 5′ to 3′ direction.

Answer:

The two statements that are true for the leading strand in DNA are "it is synthesized toward the replication fork and it is synthesized in the 5′ to 3′ direction"

Explanation:

Leading strand in DNA is the strand of new DNA being synthesized in the same direction where the replication fork is moving. The movement of replication fork allows the access of template for the new DNA. The DNA synthesis is continuous in the leading strand. It is synthesized in the 5' to 3' as DNA synthesis always takes place in this direction. This is because dNTP ( deoxyribonucleoside triphosphate) provides free 3' OH group where new dNTP can be added by the enzyme DNA polymerase.

alina1380 [7]

Answer:

Option D,  a research paper published in an academic journal and an approved PhD dissertation

Explanation:

Nicholas must present her discovery with back up of strong literature review. This literature review must include papers published in good journals and only approved research dissertation.  

An internet blog, news article and college level textbook are not considered as an approved study. These are not reviewed or approved by any peer group or associations.  

Good papers of any good journals are reviewed and examined thoroughly by the peers and thus they can be used as a backup of any study.  

Hence, option D is correct
