The Vascular system transports water and sugars throughout the plant during photosynthesis.
The hormone produced by the placenta that stimulates the ovaries to continue producing estrogen and progesterone is called the follicle stimulating hormone. This hormone stimulates the ovarian follicle allowing the egg to grow thus producing continuous supply of estrogen and progesterone.
Species evolve independently possibly due to geographical isolations or behavioural isolations.
Geographical isolation includes the isolation of 2 groups of the same species. Since these 2 groups live in different locations, (e.g. a volcanic eruption resulting in a barrier between one side of an ocean and another side of the ocean), they will have different selection pressures in their different environments as well (e.g. one side of the ocean may have more sunlight and thus more underwater plantations than the other side of the ocean). Natural selection will eliminate those with disadvantageous characteristics (e.g. Fishes that only eat plants and nothing else on the side of the ocean with little plantations) with unfavourable alleles, and select for those with advantageous characteristics (e.g. Fishes are able to eat plants and other organic substances as well on the side of the ocean with little plantations) with favourable alleles.
Since the 2 groups have different selection pressures, natural selection will occur in different ways, selecting for and against different types of fishes with different types of alleles. Also, because of the barrier, they are not able to mate with each other, and there are no mixing of genes from one side of the ocean and the other side. They are genetically isolated. As genetic drift occurs over time, their gene pools become different from each other. Thus, they evolve independently.

Metabolism (aka basal metabolic rate)!
How I remember this is the amount of energy someone in a coma would need to maintain a healthy weight

Answer:
<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>
Explanation:
As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.
Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
