A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35

percent. However, when five independent laboratories conducted the same experiment, they measured a reduction rate of only 5–8 percent.
How did these laboratories show that the pharmaceutical company’s claims were invalid?

The labs used the pharmaceutical company’s inadequate data.
The labs produced false data.
The labs recorded data incorrectly.
The labs were unable to reproduce the pharmaceutical company’s data.

<span>The labs were unable to reproduce the pharmaceutical company’s data

An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.

snow_lady [41]

Answer:

5.12μg of DNA

Explanation:

PCR is a method use to amplify DNA. It often require primers ( short sequence) nucleotides, heat stable polymerase enzymes, and thermocycler.

DNA strands are double by every cycle of PCR and it denoted by the formula 2^n  where n is the number of  cycle.

starting with 5ng,

the amount after 10 cycles = 2¹⁰ × 5 ng = 5.12μg of DNA

All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Sindrei [870]

Answer:

The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.

Without these valuable organic molecules living organisms can not survive , grow and develop.

The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.

Explanation:

Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.

Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.

A neuron that carries information away from the central nervous system
Stels [109]

Answer:

Axon also called nerve fiber carries information away from the central nervous system

Explanation:

Neurons have their own structure whose main parts are the nucleus, cell body, and dendrites. There are many connections between neurons thanks to axons or small branches.

Axons help create a network whose function is to transmit messages from neuron to neuron. This process is called a synapse, which is the joining of axons to pulses with a velocity of 0.001 seconds.
