Answer:
The correct answer is: Yes, this is an example of Reproductive Isolation.
Explanation:
- Reproductive Isolation can be defined as the mechanism adopted by different species during the course of their evolution, due to which the individuals belonging to different species are incapable of mating with each other and producing viable offspring.
- The given question is an example of Mechanical, Pre-zygotic Reproductive Isolation.
- Prezygotic Isolation refers to the mechanism adopted by individuals of different species during the course of evolution such that successful fertilisation of gametes from individuals of different species never occur, hence a viable zygote is never formed.
- Mechanical Isolation refers to the mechanism adopted by individuals of different species during the course of evolution such that their reproductive organs or the organs that assist in the process of reproduction are incompatible to each other. Hence, the gametes of each species are unable to come in vicinity of each other.
- Here, the pollen grain from the flower of one species of juniper is unable to form the pollen tube when its sits on the stigma of the flower of another species of juniper. This is an example of Mechanical Isolation.
Answer:
The probability is 99.99%
Explanation:
Because the probability that the DNA of a random person matches the DNA of the crime scene is 1/10000, that is 0.01%, then the probability that Kevin is guilty after the test is 9999/10000, that is, 99.99%.
Answer:
A scientist needs to share his work with the scientific community in order for it to be recognized. The ways in which scientists can share their results are:
- The scientists can publish their work in journals. Journals are the best method to communicate a scientists work with the scientists of the world. Even some journals have the criteria to publish only peer-reviewed articles so that the work is highly authentic which is being published.
- Scientists can also present their work at different conferences. Scientists from the world gather up for these conferences.
- Scientists can also present their works to the media or to the universities.
