Explain how the failure to regulate detrimental practices on private property might have widespread negative environmental conse
olganol [36]
The environmental effects of harmful practices on private property are not essentially restricted to private property, it can also affect public property. Water polluted on private property might stream down into a local river or an aquifer used for public purposes like drinking water or for recreational parks (swimming pools). Landowners who slaughter travelling animals on their property are putting an end to creatures that are part of a bigger ecosystem; the loss of these animals will affect all the ecosystems along the migration route.

Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans true or false ?
PtichkaEL [24]

"Kidneys are often compared to filters because they cleanse unwanted waste from both frogs and humans" is TRUE.

Answer: Option A

<u>Explanation: </u>

Frogs also have the excretory system with two kidneys and similar to mammals. Its function is to eliminate the nitrogen product from the blood. Frogs make large volumes of dilute urine to wipe out harmful products from the tubules of the kidneys.

Tadpoles and aquatic frogs excrete the nitrogen as ammonia, but most terrestrial adults excrete it mostly as urea which is less threatening substance. A few tree frog species with little water access excrete the still less harmful uric acid.

What observed reaction did the epinephrine have in the rate of blood flow in the arteriole and capillary?
lidiya [134]

Answer:

The epinephrine reaction is a decrease in the rate of blood flow in the arteriole and capillary, due to a phenomenon of vasoconstriction.

Explanation:

Epinephrine, or adrenaline, is a hormone produced by the adrenal cortex, which acts as a neurotransmitter for the sympathetic nervous system.

One of the effects of epinephrine is the <u>vasoconstriction of blood vessels, predominantly arteries</u>. Vasoconstriction of arterioles and closure of capillaries is an effect of epinephrine that results in a decrease in the rate of blood flow at that level.

This response can be seen when exogenous epinephrine is used to control an allergic or anaphylactic reaction, counteracting the vasodilation that characterizes these conditions.
