Answer:
Renal capsule.
Explanation:
The renal capsule is known as a fibrous layer. That fibrous layer helps to cover the kidney in a layer of perirenal fat (known as the adipose capsule). The renal cortex is known as the outer part of the kidney where ultrafiltration occurs. It is present between the renal medulla and the renal capsule.
The renal capsule is important for the physiological function of the kidney in the human body. It helps to influence interstitial pressure and consistently tubular reabsorption of water and sodium.
Answer:
Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.
<u>Phyletic</u><u> </u><u>gradualism</u> - slow, but constant gradual change; supported by transitional species in the fossil record
<u>Punctuated</u><u> </u><u>equilibrium</u>- long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found.
Temperature, pressure, wind speed and direction, cloud coverage,precipitation and humidity
