More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.
<h3>What is Vasoconstriction?</h3>
This is the process which involves the narrowing of the blood vessels through their muscle wall.
They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

Answer:
A. What is your diagnosis here?
As per symptoms and incident of puncturing left arm with nail from an old barn indicates it can be infection of Clostridium tetani causing disease tetanus.
When such kinds of wound occurs, there should be injection of tetanus immunoglobulin (TIG) immediately. This injection contains antibodies against Clostridium tetani which can kill the microorganism. It should be injected as soon as possible. But this is short term immediate medication.
B. What is the proper treatment of this problem?
For the treatment antibiotic penicillin, metronidazole or tetracycline can be given, it prevents multiplication of bacteria and production of neurotoxin from bacteria. these neurotoxins are responsible for muscular spasms. Along with antibiotic some anticonvasculants, muscle relaxants can be given to reduce spasms, anxiety.
C. How could this have been prevented?
This infection can be prevented by giving its vaccine in childhood itself. Vaccine is given in the form of DTaP vaccine (diptheria, tetanus toxoid, acellular pertusis). It is given in 5 shots. It is given in the arm or thigh when child is at 2 month age, 4 month age, 6 month age, 15 to 18 month age, 4- 6 years of age.
Explanation:
The answer is a. because bacteria are prokaryotes and therefore don't have mitochondria
As heat and pressure increase, ductile deformation becomes more likely
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
