The similar pattern of the phylogenies suggests the characteristics co-speciated with one another. Which of the choices is an accurate statement reflecting the figure shown? a. This is not an example of co-speciation. b. Each phylogeny represents the variation present in each population of the flower and the moth. c. The flowers and moths coevolved, so that spur-length and tongue-length each evolved because of changes in the other. d. The flowers and moths cannot co-speciate because co-speciation only occurs in host-parasite relationships. e. The flowers and moths experienced the same allopatric speciation events during their history.

The flowers and moths experienced the same allopatric speciation events during their history.

Explanation:

Co evolution may be defined as the process of the evolution of more than two species together that oppositely affects the evolution of each other. The natural selection provides the base for the co-evolution.

The co evolution generally occurs in the flowers and its pollinating species. The moth and the flower speciation represents the co evolution because both evolution are affected by each other. They have experienced the co evolution due to the allopatric speciation event and leads to teh genereation of the specific change in the characteristics.

Thus, the correct answer is option (e).

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

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.
