After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.
I believe it’s A. Not sure though
Answer:
Wild boars have successfully established in areas with warm climates.
Explanation:
As you can see in the description of the map shown in the question above, wild boar, although an invasive species in the USA, settled more easily in Texas, California and Florida, and along the southern notes, which are regions that usually have a climate hot most of the year. This means that wild boars have greater affinities with warm climate regions within the country.
An invasive species is one that is taken to a region where it does not occur naturally. These species can become real pests if the invaded environment does not have natural predators that limit their multiplication.
Answer:
Explanation:
Vertebrates are members of the kingdom Animalia and the phylum Chordata ((Figure)). Recall that animals that possess bilateral symmetry can be divided into two groups—protostomes and deuterostomes—based on their patterns of embryonic development. The deuterostomes, whose name translates as “second mouth,” consist of two major phyla: Echinodermata and Chordata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.
Deuterostome phylogeny. All chordates are deuterostomes possessing a notochord at some stage of their life
