C) In 1946, the Argentinian government imported fifty beavers from Canada, which were to be released in Cami Lake with the intention of creating a commercial fur trading industry. Though a viable industry ultimately failed to materialize, the introduction of the beavers into the region has had far-reaching consequences.
Let me go look this up ill be right back okay....

A Land mass is large geographical area that is surrounded by oceans. Therefore this can be synonymous to continents.
Explanation:
The crust is divided into tectonic plates that are dynamic because they move on top of the semi-plastic mantle. The movement of the tectonic plates is driven by the convection currents of the mantle that drag along the crust above. The tectonic plates collide at convergent boundaries where tectonic plates are consumed as one is subsided into the mantle. On the other hand, new crust is formed at divergent boundaries where two tectonic plates move away from each other and magma rises from the mantle and cools into new crust.
The convection currents occurs because the lower mantle is hotter and less dense compared to the cooler denser upper mantle. Therefore the upper mantle always tends to sink as the lower mantle rises. These convection currents are the same as in any other fluids that are disproportionately heated.

Answer:
Rough ER
Explanation:
This type of Endoplasmic Reticulum has ribosomes around its outer membranes hence is a major organelle in the processing of cell proteins. When polypeptide chains are formed in the ribosomes, they enter the lumen of the RER where they are folded properly using chaperones and post-translational modification carried out on them.
Answer:
The autosomal trait are present on the autosomes and does not have any influence on the sex of the organism. Two main types of autosomal trait are autosomal dominant and autosomal recessive trait.
a. The trait discussed in the question must be the autosomal dominant trait. As the normal and affected children are produced by the affected parents cross. The appearance of the normal child determines that the trait is dominant.
b. Since both the parent are affected but the normal child has been produced from the cross. The parents must be heterozygotes for the trait, (Aa). Their cross will produce the progeny AA, Aa and Aa (affected) and aa (normal).
