Answer:
B. increasing osmotic pressure in the glomerular capillaries that reduces the amount of filtration
Explanation:
An organ is:
A. a small structure within a cell. b. a structure composed of several tissue types. c. the basic structural unit of all living organisms. d. a group of organs with a common set of functions. e. a group of cells with similar structure and function
Answer:
b. a structure composed of several tissue types.
Explanation:
There are several levels of organization of life in living things, which progresses from simple structural level to more complex ones. The cell is the basic unit of life capable of carrying out virtually all life’s functions. Cells are composed of several structures known as organelles. Similar cells with similar functions associate to form a tissue at the tissue level. The next level of organization is organ level. Several tissues associate together to form an organ. An example of an organ is the liver. Several organs can as well associate together to form the organ system at the system level of organization.
Answer:
The inability to function as catalyst.
Explanation:
DNA is the genetic material present in all organism except some viruses. DNA shows all the properties to work as the genetic material according to the today's environment.
Researchers believe that DNA was not the first genetic material in the early environment. The genetic material should have the catalytic activity in the early forms of life and DNA cannot work as the catalyst. The catalytic property of the genetic material is important in the early , rapid and changing environment. Hence, DNA was not the genetic material in early forms of life.
Thus, the answer is inability of DNA to function as catalyst.
Using Kepler's 3rd Law of planatary motion we know that the sqare of the orbital period is proportional to the cube of the semimajor axis.
So we know the earth is 1 AU from the sun with a period of 1 year so we can set up a ratio as follows:
P^2 / r^3= 1
(P)^2 = 4^3
<span>P = 4^(3/2) = 8 years </span>
