Answer:
Natural selection is least likely to occur in this population if:
- The resources are continuously available
For a species to survive in an area, it is essential that the place has enough resources like nutrients, space, water etc. If these resources are available then there will be less chances of competition which will lead to lesser chances of natural selection.
- The number of of death rates is equal to the number of of birth rates
In an balanced ecosystem, the number of birth rates is equal to the number of death rates for a population. If the number of death rates is lesser to the number of birth rates then the competition for resources will lead to natural selection.
Answer: Rock layer H is much newer than rock layer M. If all layers were perfectly stacked, the lower layer would be older. However, since we can see Layer H was probably formed by a crack that was filled with magma, Layer H will be newer.
Hope this helps :)
Answer:
Option (4).
Explanation:
Hypersensitivity may be defined as the hyper immune response of the body. Hypersensitive is also known as hyper sensitive reaction that may be uncomfortable and harmful for the individual.
Type IV hypersensitive reaction is also known as delayed type of hypersensitivity that are generally mediated by T cells. Hemolytic disease of new born is an example of Type II hypersensitive reaction and not related to Type IV hypersensitive reaction.
Thus, the correct answer is option (4).
This statement is incorrect because every dinosaurs has a different DNA so is impossible to be cloned
Because natural selection is caused so that an organism can adapt and better survive their environment. They are involved in the formation of fossils because organisms that die are buried in sediment and become fossils.
