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 seal is a mammal. How can it survive in the cold polar seas when a human can die in a few minutes
Answer:
adaptation
Explanation:
it's body adapts to the cold plus they have a very thick skin
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.

Jorge is testing the effect of lead on child development. Based on his observations, he finds that the longer the children are exposed to lead-based paint, the higher the chance becomes that the children may develop behavioral problems. He has done repeated experiments, and his results are similar to the results of many other scientists.
Why is this scenario considered a theory rather than a hypothesis?
It is a testable scenario.
It is based on prior knowledge.
It is a well-tested explanation.
It is a factual statement.
Answer:
(C) it is a well tested explanation

Climate change has begun to affect insects as food resources have started disappearing . The monarch butterfly and the queen butterfly have to compete for the same food source . This is an example of____competition.
A. Co-species
B. Intraspecies
C. Interspecies
D. Habitat
Answer:
B.
Explanation:
In an ecological environment living things of different or same species compete with each other for the limited resources available. It is a symbiotic interaction between these living things.
There are two types of competition between these living beings- intraspecific and interspecific. In the given scenario, it is an intraspecific competition between the monarch butterfly and the queen butterfly.
Intraspecific competition is a competition between two living beings of the same species.
The monarch butterfly and the queen butterfly both belong to the same species- danaus.
Therefore, option B is correct.

A toad is brought into a new ecosystem. It is stronger than the toads that
already live there and reproduces quickly. Which is the best way to describe
these toads in the new ecosystem?
A. Invasive species
B. Native species
C. Keystone species
D. Cyclical species
Answer:
a
Explanation:
newer, stronger, and reproduces more
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.

Skates have whip-like and flat pectoral fins.
Explanation:
The tails of Ray and Skates are different from other fishes because Ray and Skates have whip-like tails that helps their kite shaped body in movement from one place to another. Both Skates and rays have pectoral fins that are flat and expanded, as well as fused to the head of both organism while on the other hand, fishes have different shape of pectoral fins that are not flat which helps to change the direction of the fish during its movement..
When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium

An individual has type ab blood. The father has type a and the mother has type b. What is the individual's phenotype an example of
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.
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?
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
