What percentage of glomerular filtrate becomes urine?

1 answer:

5 0

Only about 1% of the glomerular filtrate becomes urine. This is one of the many facets of Renal Physiology. The nephrons are the part of the kidneys which are responsible for filtering the blood. Along with the blood are cells, proteins, and large molecules that also filtered by the nephrons through the process of ultrafiltration. Only a few of these deposits are turned into urine when they reach the collecting ducts of the kidneys.

ki77a [65]

Answer:

Stream volume and speed directly affects the size, shape, and flow of streams and rivers.

Explanation:

The greater volume results in larger channels and these larger channels will make the flow of stream faster.
The flow volume of different streams are related to precipitation and run-off.
The earth materials also heavily effect the flow by changing the properties of the water like increase in the mass, hardness, shape, etc.
Erosion and deposition is common in the curving type of stream.

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogou

Increasing the number of stomata per unit surface area of a leaf when atmospheric carbon dioxide levels decline is most analogous to a human

B. putting more red blood cells into circulation when atmospheric oxygen levels decline.

<h3>What are stomata?</h3>

The stomata are apertures in the epidermis, each bounded by two guard cells. There are small openings on the lower surface of the leaves. These pores are called stomata. Loss of water from the stomata creates an upward pull, that is suction pull, which helps in the absorption of water from the roots. That is helpful for the transpiration process. They help in exchange for gases. Any of the tiny pores or openings in the epidermis of leaves and young stems are referred to as a stomate, sometimes known as a stoma, the plural of which is stoma or stomas. On the underside of the leaves, stomata tend to be more numerous. They enable the exchange of gases between the atmosphere outside and the leaf's branching network of interconnected air canals.

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m

Vanyuwa [196]

This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

<span>Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
$v=\frac{2\pi{r}}{T}$
</span> $=\frac{2\pi{r}}{1.88*365.25*86400}$ m/s, accounting for leap years
$=3.371*10^{-8}\pi{r}$ m/s

The centripetal force, Fc, generated is
$Fc=\frac{mv^2}{r}$
where m=mass of mars = 6.39*10^(24) kg
$=\frac{mv^2}{r}$
$=\frac{6.39*10^{24}v^2}{r}$
$=7.26168*10^9\pi^2r$

The gravitation pull from the sun, Fg, is given by
$Fg=\frac{GMm}{r^2}$
where G=grav. const., =6.67408*10^(-11) m^3<span> kg^(</span>-1)<span> s^(</span>-2)
M=mass of sun=1.989*10^(30) kg
$=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}$
$=\frac{8.4826*10^44}{r^2}$

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
$7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}$
Solving for the real root:
$r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}$
$=\frac{1.1681263*10^{35}}{\pi^2}$
=2.279*10^11 m
