The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

Which of these products are made from a renewable resource?
aleksandr82 [10.1K]

Renewable resources are those which can be replaced naturally and repeatedly. For example, water, oxygen, and plants are examples of renewable resources.

Wood is a renewable resource as it is a part of trees. Trees are able to be replanted and can be cut down again, once they reach maturity. Plastics, glass, and steel are known as non-renewable resources as they cannot be replaced at a sufficient rate and usually have a limited supply. For example, plastics are created using a variety of different substances such as natural gas and oil (polyethylene). The Earth contains a limited supply of both substances, so plastic is deemed as being non-renewable.

As a result, the only renewable product in the choices provided above is a wooden spoon.

A frameshift mutation that occurs very early in a protein sequence would have what effect on the protein's structure? see sectio
ExtremeBDS [4]
I think a frameshift mutation that occurs very early in a protein sequence would have an effect on the structure of the protein such that the primary, secondary, and tertiary structures would be altered. A frameshift mutation occurs when a protein is drastically altered because of an insertion or a deletion. Insertions and deletions cause a change in the length of a gene, which causes a shift in the codon reading frame.
