<span>The gene, is in fact the subunit of information on a chromosome, so this is a true statement. A chromosome is a structure that occurs within cells. It contains the cell's genetic material, which determines how an organism develops. For example, if we are talking about DNA, its molecule is a very long, coiled structure that contains many identifiable subunits known as genes.</span>
The best answer is D
A freely suspended magnet will always point in the North - South direction in the absence of any other magnet. This suggests that the earth itself behaves as a magnet which causes a freely suspended magnet (or magnetic needle ) to point always in a particular direction namely North and South.
The south pole of the earth's magnet is in the geographic north because it attracts the north pole of the suspended magnet and vice versa. However it is important to note that the position of earth's magnetic poles are not well defined because they are spread over an area.
Answer:
Cell membrane/plasma membrane;
Nucleus;
Cytoplasm
Explanation:
Makena's model is synonymous with that of an animal cell.
The soft flexible putter layer of the egg can be likened to the cell membrane of an animal cell. Cell membrane, also called plasma membrane, just like the soft and flexible exterior of the egg, is a semi-permeable that serves as a barrier between the external environment of the cell and it's inner environment. It controls what goes in and out of the cell, as well as help in the selectively exchange of ions and molecules, in and out of the cell.
The yolk in Makena's model represents the nucleus of an animal cell.
Also, the surrounding area between the yolk and the exterior of the egg, represents the cytoplasm found in animal cells. The cytoplasm is filled with fluids and surrounds the nucleus.
Walking upright.
You can make a case for all of them, but for three of them indirectly.
But the answer, I think, is walking upright.
You can look at the pelvic bones and femur orientation in the hips. You can also look at the way the skull sits on the vertebra.
Chimpanzees have a skull that sits more downward, because they walk on all fours most of the time. While humans have skulls that sit more horizontally on the vertebra, which allows us to see out on the horizon more easily. We can do that because we stand on two feet.
I hope that helps.
