Answer:

Scientist count the world humans population with an organization called The United Nations Population Division (UNPD),

Explanation:

Which keeps track of the world population, projects that the world's human population will hit 7 billion on Halloween Day 2011. Admittedly, that is just an estimate: There's no way to know exactly how many people are alive at any given moment, and the true date that humanity's ranks will surpass 7 billion could come in the weeks or months before or after Oct. 31. Nonetheless, the UN's guess is the best there is.

Studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.
Diano4ka-milaya [45]

The question is incomplete. The correct question is as following:

__________ studied the role of RNA in protein synthesis, specifically in the bacteria E. coli.

Answer:

Marshall Nirenberg and Heinrich Matthaei

Explanation:

Marshall Nirenberg and Heinrich Matthaei are two biochemist and geneticist who studied the functional importance of RNA in the process of translation (protein synthesis) experimentally in E.Coli.

Nirenberg and Matthaei discovered the first codon out of 64 codons present in RNA and they successfully performed translation (protein synthesis) in E.coli in a test tube. They decoded the first codon UUU (phenylalanine) by using synthetic RNA having only uracil nucleotides in a E.Coli and later they decoded further codons.

So, the correct answer is  Marshall Nirenberg and Heinrich Matthaei.

A feeding adaptation an iguana has is it’s short nose. This feature is important for feeding because it helps it eat algae off rocks.

Marine and Land iguanas have similar traits even though they aren’t the same kind of iguana because, most of their predators are the same. Therefore a bird or other prey would not be able to tell the difference so that’s why land and marine would both need spines on their back.

I think the camouflage is the most beneficial in land iguanas because their predators can’t spot them that easily, and it’s a quick way to blend in. I also think that the iguanas nose on marine iguanas is the most important because when they eat algae it’s easy to eat and they don’t have to change their position when feeding.
