Most likely the students are using a crude measurement of time, like a stopwatch. They would get the best results with a scientific apparatus that uses a computer and optical sensors. Even recording their dropped objects with a video camera and analyzing the video would give more consistent results. Results will also vary greatly if different people are taking the time measures instead of one person making all measurements.
Answer:
Provides both the RNA and the polymerase needed for synthesis
Explanation:
Telomerase is an enzyme which extends the telomere sequences present at the end of the chromosomes. The telomerase enzyme acts as DNA polymerase as well as provides the RNA which serves as a template strand rather than the primer.
The polymerase acts as a reverse transcriptase enzyme and synthesizes the DNA strand from the RNA template. Since the telomerase provides RNA and acts as DNA polymerase, therefore, it is known as the ribonucleoprotein molecule.
Thus, the selected option is correct.
Answer:
Replacement rate
Explanation:
In biology, replacement level or replacement rate refers to the amount number of offspring required to be produced to keep the level of population at a stable state without causing it to much decease.
Scientists use the replacement rate of plant and animal specie to assess the rate at which the population is reproducing at a stable level or are at some threshold zone and need to be taken care of.
Here in question, we see that some specific properties of mustard plants are focused that, plant survives only one month during which it produces 50 flowers. each flower produces a fruit containing 20 seeds.
It clearly do not depicts the population size of mustard plant, or niche or fitness, it just describe the replacement rate that how many offspring does mustard plant produce to keep its population at a stable or steady state without being getting into a danger of extinction.

Answer:
In my own words, this summary equation tells me that:
When glucose reacts with oxygen, carbon (IV) oxide and water are given off and energy is produced.
Explanation:
Cellular respiration is known to be a metabolic reaction which actually occur in the cells of living organisms whereby chemical energy is converted into energy (ATP) and certain waste products, carbon (IV) oxide and water are released. We can simply put that cellular respiration is a process of converting sugars to energy. In the giving equation, we can see that glucose which is a sugar reacts with oxygen to give CO₂ and H₂O.
