E=mc^2

c is speed of light

E=1.7\times (3\times 10^8)^2\\\\E=1.53\times 10^{17}\ J

Which statement is true about climate change and biodiversity?
8090 [49]
Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.

Answer: C. It can help some species and hurt others.

andrew11 [14]

Answer:

deuterostomes

Explanation:

During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
