Answer: It is the result of a mixture of radiation from many independent sources, such as stars and galaxies.
Microwave background radiation is a form of electromagnetic radiation that is present in the whole universe and completely fills it. In fact, it is the leftover radiation from the Big Bang that occurred 400,000 years before the events related to this cosmic radiation.
Its frequency belongs to the microwaves range and is one of the main demonstrations of the of the Big Bang theory model.
Answer:
C. Physical
Explanation:
The Rio Grande river is an example of a physical boundary between two countries since it is a landform. Physical boundaries are very diverse and can include oceans, seas, mountains, rivers, and lakes, just to name a few of the many landforms that can make a physical boundary.
A cultural, geometric or religious boundary could perhaps be visible with the right type of map, but a river does not tell us anything about the religious makeup of a certain area, nor does it reflect the cultural of the inhabitants.
Answer:.......... The densest surface water masses in the oceans are the North Atlantic Deepwater and Antarctic Deepwater.

The correct answer for this question is this one:
Given that there are 30 people, then there are 60 alleles. 10 of these people are not tasters. So, there are 20 of those 60 are t alleles. So, 40 alleles are left, but of a mix of t and T. It said in the lesson text that people who can taste this have at least one dominant gene "T". So it could either be homozygous (T,T) or heterozygous (T,t or t,T). People with homozygous recessive genes (t,t) can't taste it.
