A strain of Neisseria gonorrhea has a mutation which has caused it to lose the ability to produce fimbriae and become less virulent as a consequence. What function has this pathogen lost

Answers

Answer 1

Answer: The pathogen has lost the function of the ability to adhere to cells of the body.

Explanation:

Neisseria gonorrhea is a gram negative bacteria that has the ability to attack and cause disease in man using its virulent factors. It is know to attack the urethra of both male and female producing an acute urethritis and tenda to spread locally if not treated. The virulent factors determines the ability of the organism to infect or damage it's hosts tissues and they include:

--> endotoxins

--> pilli

--> fimbriae

--> capsule polysaccharide expression

The fimbriae is one of the virulent determinants which the organism uses to attach to the host cells. As these bacteria multiple and grow, there are chances of mutation occuring. MUTATION is defined as the errors during DNA replication or induced by exposure to mutagens (like chemicals and radiation)

If the bacteria is affected by mutation, which can cause the gene for fimbriae production not to be expressed, the virulent factor of the organism will be highly affected as the first step to cause an Infection which is attachment is lost.

A cylindrical tin full of engine oil has a diameter of 12cm and a height of 14cm.The oil is poured into a rectangular tin 16cm long and 11cm wide. What is the depth of the oil in the tin?​

Answers

Answer:

Depth = 9 cm

Explanation:

First, calculate the volume of the cylindrical tin.

Mathematically, that would be the following:

[tex]V = \pi * r^{2} * h[/tex]

Now, r = d/2 = 12/2 = 6 cm

h = 9 cm

Therefore, the volume will be:

V = 22/7 * 14 * 6^2 =1,584 cm^3

Now, to find the the depth of the tin, we have to realize that the content of the cylinder should fill in the tin to a particular height.

As we don't have the height of the tin so let's suppose it x, now it means that

l * b * h = 16 * 11 * x = 176x

Therefore, the depth would be:

176x = 1584

x = 1584 / 176 = 9 cm

A seal is a mammal. How can it survive in the cold polar seas when a human can die in a few minutes

Explanation:

Answer:

[tex]\huge\boxed{Answer\hookrightarrow}[/tex]

It doesn't depend on whether the seal is a mammal or not. A seal has a thick layer of fat - 'blubber' that helps them to stay warm in the cold polar seas. This layer of fat or blubber is not found in humans as we live in warmer areas & hence don't have a need for it. So, humans will die in the cold polar seas without extra protection unlike seals.

Answers

Answer:

Codominance

Explanation:

Codominance is a type of inheritance pattern in which two alleles of a gene both express themselves in a heterozygous state. Codominance occurs when neither of the two alleles involved are recessive instead both dominate simultaneously.

As described in this question, the father of an individual has type A blood and the mother has type B. However, the individual has type AB blood. This is because alleles for blood types A and B both phenotypically express themselves in the individual. Hence, blood type A and B are said to be codominant and the AB phenotype is showing an example of CODOMINANCE.

Explanation:

this means that the other animals would have to compete and they usually lose.

Invasive species is the best way to describe toads in the new ecosystem. Therefore, option (A) is correct.

What are invasive species?

Invasive species are non-native organisms that are introduced to an ecosystem and have negative impacts on the environment, economy, or human health. They typically outcompete native species, reproduce quickly, and lack natural predators in the new ecosystem.

The fact that the toad is stronger than the toads already living there and reproduces quickly suggests that it may outcompete native toads for resources and space. This could potentially lead to a decline in the population of native toads, which could have negative effects on the ecosystem.
