The scientists should conclude that other data must be considered in order to make a valid conclusion.
<h3>What is Archaefructus?</h3>
Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now thought to be approximately 125 million years old, or early Cretaceous in age.
Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants.
Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are produced on an elongate stem rather than condensed into a flower as in modern angiosperms,
Archaefructaceae has been proposed as a new basal angiosperm family.
An alternative interpretation of the same fossil, however, interprets the elongate stem as an inflorescence rather than a flower, with staminate (male) flowers below and pistillate (female) flower above.

Answer:
when the light increases the rate of photosynthesis is going to be fast as well
There are a couple reasons the ice is important to polar bears, but given the choices you have the correct one would be:
A. The polar bears can’t out swim the seals, so they sit quietly on an ice platform and attack the seals when they come up for air.
A limiting factor is anything that constrains a population's size and slows or stops it from growing. these factors are mostly biotic . For example, Food or mates. Even competing for resources. Factors for the rate of photosynthesis range. The rate of oxygen output, carbon dioxide uptake, carbohydrate (glucose/sugar) production, temperature is also a limiting factor because At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates. At high temperatures, enzymes are denatured. As well as light intensity because without the sun it’s not even possible
