Which of the following is not a possible consequence of the introduction of invasive species?
a. changes to the existing gene pool
b. changes to an area s diversity
c. fragmentation, destruction, or alteration of habitats
d. no consequences

The correct answer is option d. No consequences.

The invasive species are those species, which are not native to a particular ecosystem. There native ecosystem is somewhere else than the region, in which they are present.

The introduction of the invasive species generally causes the disturbance to the ecosystem, as they exploit various resources present in the ecosystem and causes the suffering of the native species by increased competition and lack of vital components. Hence, the invasive species can easily change the diversity of the area and cause the changes in the gene pool. The species also affect the habitat and cause it destruction or alteration. So, they cause a lot of consequences to the ecosystem.

explanation:

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
