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 .

HELP PLEASE ASAP.<br> Why do stems have bark? What does the phloem do?
lozanna [386]

Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

Which statement regarding Bax and Bak, two members of the Bcl-2 family, is true?
vampirchik [111]

Answer:

Option D When activated, Bax and Bak form oligomers in the outer membrane of mitochondria, leading to the release of cytochrome c.

Explanation:

The proapoptotic genes are involved in the process of apoptosis. The antiapoptotic gene prevents apoptosis that is cell death. The proapoptotic genes are bax, bak, bad and bid. The bcl family genes are antiapoptotic genes. The process involved activation of apoptosis inside the cell is called intrinsic pathway of apoptosis.

The activation proapoptotic genes, Bax and Bak form oligomers in the mitochondria outer membrane. These pores in the mitochondrial membrane allows the release of cytochrome-c that further attaches with Apaf-1. This leads to activation of caspase 9 that further activates caspase 3, thus inducing apoptosis.
