If this data stays consistent, what would you predict the score would be if the student studied for 5 hours?

What is Ms. Navi's favorite color?
Pink
A population of birds lives on an island where seeds are their main food source. After a severe drought, most plants die and seeds become very scarce. However, some birds in the population can also eat insects. Over several generations, the population changes.
How will this environmental change most likely affect the bird population over time, and why?
Birds that can also eat insects are more likely to survive and reproduce, so that trait becomes more common in the population through natural selection
A 10 kg cart is pushed with a force of 50 N. Using F = m x a, find the acceleration.
5 m/s2
Deforestation removes large areas of trees in a region. How does this affect atmospheric carbon dioxide levels?
CO₂ levels increase because fewer trees are available to absorb carbon dioxide.
What is the carrying capacity of this population?
~80
Name one of the places Ms. Navi has traveled to THIS YEAR
San Diego, Hawaii, Seattle
A genetic trait for flower color in a plant is controlled by two alleles: P (purple, dominant) and p (white, recessive). A heterozygous purple plant (Pp) is crossed with a white plant (pp).
What percentage will have white flowers?
50% of the offspring will have white flowers (pp)
A student calculates the force on a 10 kg object accelerating at 6 m/s² and gets 16 N.
Use F = m x a
What is wrong with the student's answer? What is the correct answer?
Miscalculated; F = 60 N
A region experiences warmer temperatures over several years. As ice in polar areas melts, less sunlight is reflected back into space, causing even more warming. This leads to even faster ice melting.
Identify the type of feedback loop and explain how it works in this situation.
Based on this graph, when did the sea otters reach carrying capacity? AND what is the approximate carrying capacity?
