According to a new study, spider's fangs are considered to be natural needles that they use for piercing the skeletons of prey and delivering the kiss of a venom. The fangs can also be used as a defense mechanism towards their predator or towards humans.

On the other hand, the crustacean's claws, like the crab claws can be used for protection, as well as for communication, excavating burrows, attracting mates and gathering food.

While the centipedes use their claw to grab their prey and inject venom to kill it or to protect itself from being harmed.

Considering these definitions, we can say the Gerri and Alana are both correct since the spider uses its fangs to inject venom like the centipede and to protect itself like the crustaceans.

How are luciferin and luciferase used today
alisha [4.7K]

Answer:

Luciferin is used, for example, in reporter gene assays to study gene regulation and function where expression of the luciferin-tagged reporter is a marker to indicate successful uptake of the gene of interest in recombinant DNA techniques. Luciferase is a heat-sensitive protein that is used in studies on protein denaturation, testing the protective capacities of heat shock proteins. Luciferase is an enzyme used for bioluminescence by various organisms in nature, most famously the firefly. The scientist produces a construct in which the regulatory region of a target gene is fused with the DNA coding sequence for luciferase

Drag and drop the appropriate labels into position to explain how this defect might cause mr. g's other problems.
marissa [1.9K]

How does Mr. G's altered blood flow explain his signs and symptoms? Drag and drop the appropriate labels into position to explain how this defect might cause Mr. G's other problems. Fill the boxes in order, starting with 1, then 2, etc

(Image attached)

Answer:

  1. When left ventricles contracts, some blood goes up through mitral valve into the left atrium, Turbulent flow through the valve causes systolic murmur. the atrium is overfilled and dilated.
  2. Because some blood re-entered the mitral valve, less is pumped out into the aorta. the ejection fraction is only 43%
  3. Less blood enters aorta, so SBP is low. Baroreceptor reflex causes increased heart rate; wall of overworked left ventricles becomes thicker
  4. Because its already partly full of blood from the ventricle, the left atrium accepts less blood from the lungs, the lungs overfilled with fluid; resulting in troubled breathing.

Explanation:

A murmur is a result from a abnormal blood flow to the heart.Its basically an unusual sounds that is heard between heartbeat A systolic murmur occurs when the heart muscles contracts. i.e they begin and end between S1 and S2.

From the above information, it seems like Mr G is experiencing mitral regurgitation. It is a condition where mitral valve doesnt close tightly and as a result the blood flows back from the left ventricle into the left atrium.
