Answer:
Sympatric speciation.
Explanation:
Sympatric speciation occurs between Crematogaster ashmeadi and Linepithema humile ants because they live on the same geographical location. Sympatric speciation is a type of speciation in which ancestral population evolve into separate species without separation of geography. Hybrid sterility is the postzygotic isolating mechanism that decreases the fitness of the hybrid individuals and helps in controlling the population of an organisms..
Answer:
b. the 20 amino acids found in proteins differ in the composition of their R groups, which may be either polar or charged.
Explanation:
Since the proteins are polymers joined by a big number of amino acids, all the joins occur the same way because in all the amino acids there is always one part that is exactly the same in all of them.
The rest of the molecule in the amino acids, the R group, is different in each one, that is the characteristic of each one, and this is the part that can give the name and some other chemical properties.
Answer:
The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.
Explanation:
As the vertical axis is labelled as average plant mass, it will make the y- coordinate.
As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.
The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.
10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.
Hence, Dis the correct option.
<span>I believe the answer would be B - the toy car would hit another toy car that would in turn hit another toy car, and so on. A wave has a ripple effect, so it will continue to happen down the line, until there is a force that stops it, or there are no more cars to hit.</span>
Answer:
<u>Option:</u>Symbiosis in which both organisms benefit ecological niche.
Explanation:
- <u>Symbiotic association between any living organism:</u>
The symbiotic association is the connection between any organisms, which are either benefited by each other or the relationship can be very negative for the either one, or it may be neutral in nature for both the organisms living inside a symbiotic relationship.
The symbiotic association between the different organisms are of four different natures or levels,which are as follows:
- <u>Mutualism:</u> Inside the relationship or connection between any number of organisms in which there is mutual benefit for both the organisms, is called as the mutualism. For example, the insecticides living in the plants roots or any part of its body.
- <u>Parasitism:</u>Such a symbiotic relationship is which between any two living organism either one of them is benefited while the other one is harmed by its effect. For example, the tape worms in the living body.
- <u>Predation:</u> It is more simple to understand as the prey is hunted down and killed in order to fulfill the needs of the predator.For example the lion and the impala.
- <u>Commensalism: </u>The type of association between the living organism in which one of the organism is benefited, while other is neither benefited nor harmed. For example the marine life on the back of the crab's body.
