A scientist studying fossils, found that identical freshwater reptiles about 1 meter long were found in both South America and A

frica. Since, these animals couldn’t have swum hundreds of miles across the Atlantic Ocean, what is the best explanation for how fossils of this creature were found in both places?
options:

A:The animals evolved to become the same exact species even though they lived in different environments.


B:The animals walked from Africa to South America because there used to be large valley that separated the continents, which has now been filled by the Atlantic Ocean.


C:The ancestors of this creature used to be able to fly. They flew from Africa to South America and then evolved into the freshwater reptiles the scientist discovered.


D:South America and Africa used to form a single landmass that later split apart. The fossils found on both continents shared a single habitat.

Answer:

D

Explanation: this would make sense because they could not have evolved to become the same. Evolution does not work like that . The animals would not walk or fly they are water creatures and if they did that they would not evolve back down to fish .

What is the function of the translocon in co-translational translocation of a membrane-bound protein?
Aleksandr-060686 [28]
The translocon (commonly known as a translocator or translocation channel) is a complex of proteins associated with the translocation of polypeptides across membranes.[1] In eukaryotes the term translocon most commonly refers to the complex that transports nascent polypeptides with a targeting signal sequence into the interior (cisternal or lumenal) space of the endoplasmic reticulum (ER) from the cytosol. This translocation process requires the protein to cross a hydrophobic lipid bilayer. The same complex is also used to integrate nascent proteins into the membrane itself (membrane proteins). In prokaryotes, a similar protein complex transports polypeptides across the plasma membrane or integrates membrane proteins.[2] Bacterial pathogens can also assemble other translocons in their host membranes, allowing them to export virulence factors into their target cells.[3]

4.1. In Seminar 6 we counted the number of stems (tree trunks) as a measure of species
In-s [12.5K]

Answer:

A researcher would chose percentage cover over stem count because percentage cover is a less time consuming process and easy to calculate in case of species having number of clones.

Advantages of stem count:

  • It gives exact number of individual present in the population.

Advantages of percentage area count:

  • It gives the total surface area covered by the species and is less hectic.
