A species of finch has been studied on one of the geographically isolated Galapagos Islands for many years. Since the island is

small, the lineage of every bird for several generations is known. This allows a family tree of each bird to be developed. Some family groups have survived and others have died out. The groups that survive probably have:
A) Interbred with other species
B) Inherited some advantageous variations
C) Found new places on the island to live
D) Been attacked by more predators

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 are the functions and vessels of the heart, and what are some cardiac disorders that might be life-threatening to a person
zavuch27 [327]

Answer:

The cardiovascular, or circulatory, the system supplies the body with blood. It consists of the heart, arteries, veins, and capillaries. but the things that might be life-threatening to a person or animal are;

Explanation: angina is a type of chest pain that occurs due to decreased blood flow into the heart this can harm animals and people. there is also - - - arrhythmia,which is or an irregular heartbeat or heart rhythm,

- congenital heart disease, in which a problem with heart function or structure is present from birth.

-coronary artery disease, which affects the arteries that feed the heart muscle.

- Heart attack, or a sudden blockage to the heart’s blood flow and oxygen supply this can kill. heart failure, wherein the heart cannot contract or relax normally,

- dilated cardiomyopathy, a type of heart failure, in which the heart gets larger and cannot pump blood efficiently and the last one is  

- hypertrophic cardiomyopathy, in which the heart muscle walls thicken and problems with the relaxation of the muscle, blood flow, and electrical instability develop

these are only a few that can harm or even kill a living thing like and animal or person these things are really harmful.

I hope this helps you!!

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
