If a long-day plant has a critical night length of 9 hours, a 24 -hour cycle of 14 hours light / 10 hours dark would prevent flowering.
Flowering plants are plants that bear flowers and fruits and form clade angiosperms, commonly called angiosperms.
The term “angiosperm” is derived from the Greek angeion (“vessel”) and sperma (“seed”) and refers to plants that produce seeds that are encased in fruit.
By far the most diverse group of land plants, with 64 orders, 416 families, about 13,000 known genera, and 300,000 known species. In earlier days, angiosperms were also called Magnoliophyta.
Many flowers have bright colors, strong scents and sweet nectar to attract pollinators. It can attract insects, birds, mammals and even reptiles.
When visiting flowers, pollinators pick up pollen from the anthers. When pollinators visit the next flower, some of the pollen sheds the stigma. This allows for cross-pollination and increases genetic diversity.

Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the process of diffusion in which ion or some substances are transported across the membrane by a specific carrier membrane protein. The process does not require the input of energy and is driven by a concentration gradient.
The absorption of simple sugars in small intestine occurs through facilitated diffusion. The polar sugar molecules can not cross the nonpolar inner core of the membrane. Hence, the membrane proteins transport the sugars down the concentration gradients without any input of energy.
Answer:
1.
To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).
Explanation:
The process is called condensation
