In the cross-section of a kidney, there are three main regions that become apparent. The outer region is called the "renal cortex", this is where the capillaries are mainly located. The deeper and darker region, that looks like small pyramids arranged in a semicircle is called the "renal medulla", where the filtering of the blood takes place. The flat, tube-like structure is called the "renal pelvis".
Answer: B. Poorly adapted individuals never produce offspring
Explanation:
Natural selection is a theory that states organisms adapts to its environment due to differences in their phenotypes. So, <u>individuals with favorable traits are more likely to survive and reproduce</u>. It is a key mechanism of evolution, which is the change in traits of a population over generations.
<u>Populations respond to natural selection if they contain heritable variation </u>among them, wich means that individuals differ in the traits they transmit to their offspring.
Because of the environmental selection pressures, individuals produce more offspring than their environment can support. <u>The pressure determines which individuals will survive and reproduce</u>, while others will die because of predation or diseases. So, natural selection is based on the observations of adapted individuals.
Answer:
If radioactive deoxythymidine triphosphate (dTTP) is added to a culture of rapidly growing bacterial cells, you will find the greatest concentration of radioactivity in the Nucleoid.
Explanation:
Deoxythymidine triphosphate (dTTP); is one of the four nucleoside triphosphates that are used in the in vivo synthesis of DNA. Unlike the other deoxyribonucleoside triphosphates, thymidine triphosphate does not always contain the "deoxy" prefix in its name
Radioactivity; decay is the process by which an unstable atomic nucleus loses energy by radiation
During an asthma attack, the oxygen delivery in the body is decreased / limited, due to the air getting trapped inside the lungs.
