FALSE!!
Endotoxins are just the lipid parts of a gram negative cell wall that have broken off when the bacteria dies. They are moderately toxic, cause fever and can make you pretty sick.
Exotoxins are proteins made by pathogenic bacteria (mostly gram positive). These highly toxic. Examples of diseases caused by these are diphtheria, botulism and tetanus. 
Therefore it doesn't take much exotoxin to cause a problem!

Ksivusya [100]

The organ system interacts with each other to maintain the normal functioning of the body. The composition of blood changes due to this interaction. The change is the blood going out from the lungs is deoxygenated and the one coming to the lungs is oxygenated.

<h3>What is the interaction of the respiratory and circulatory systems?</h3>

The respiratory system involves inhalation of oxygen and using this to release energy and exhalation of carbon dioxide.

The circulatory system is comprised of the heart and blood vessels. The heart pumps blood to different body organs through these blood vessels.

The transfer of oxygen is done with the help of blood. During this transfer, the composition of blood changes from being oxygenated means having oxygen to deoxygenated means having carbon dioxide.

Thus, in this way, the interaction changes the composition of blood.

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia
