Kierra is trying to decide which brand of lettuce seeds she would like to use in her garden this summer. After researching, she

picked the two best-known brands to test. She decides to test them by planting one of each seed in a small space in her yard; her observations will be recorded so she can compare.
Which is the best example of a negative impact of planting only one seed from each brand?
A) She might confuse the plants if there is only one of each, resulting in incorrect observations.
B) She will not be able to collect enough measurements to create graphs to compare her data properly.
C) Sometimes seeds get incorrectly packaged in factories; one of the seeds she plants may not truly be a lettuce seed. She would not know this until after her study.
D) The one seed she chooses from either packet may be defective and grow improperly. She would only have results from a bad seed for that brand and not have true data from typical seeds of that brand.

Even though plants cells photosynthesize, they still use their mitochondria for oxidation of pyruvate. This will occur in _____.
lidiya [134]

Answer:

All cells all the time.

Explanation:

Photosynthesis is the process of the formation of organic nutrients, glucose in the presence of sunlight by fixing CO2. Cellular respiration is the oxidation of nutrients. The process forms ATP which in turn serve as energy currency for living cells.  

Plant cells perform cellular respiration to obtain the energy stored in the chemical bonds of glucose. The energy obtained by cellular respiration is used to perform the vital functions by cells. Therefore, irrespective of photosynthesis, cellular respiration occurs in all the cells of the plants all the time to fulfill the energy requirement for growth and development.

Bill does 1500 J of work on a lever, which is a simple machine. The lever does 1350 J of work on a stone.
Oksanka [162]
Efficiency is the measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage.
Efficiency is the energy output, divided by the energy input, and expressed as a percentage. 
Efficiency = (1350/1500)×100
                = 90%
