Answer:

George Wetherill and Victor Safronov

Explanation:

The modern model known as "solar nebular disk instability model" was developed by George Wetherill after refining the basic modern model developed by  Russian astronomer Victor Safronov in 1970.  According to this model, dust and gases resulted into massive clumps during the early stage of formation of solar system. This model well explains the formation of star, sun, solar system, planet, asteroids and comets.

antoniya [11.8K]

Answer:

choanoflagellates and sponges are sister groups

Explanation:

The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

How can humans reduce the amount of endangered and extinct species?
