Why are scientific theories often so powerful?

vodka [1.7K]

Scientific theories are often so powerful because they have been tested several time by different peoples and they have been found to be true. A scientific theory is a well substantiated explanation for a specific phenomenon which has undergone many observations and experiments and has stand the test of time. Thus, scientific theories always have to be reckon with because they have been severally tested.

Considering that nearly 85 percent of corn crops are genetically engineered, which impact does genetically engineered corn have

atroni [7]

Genetically modified crops are genetically engineered such that a desired trait is enhanced or reproduced to appear in every offspring. Genetically engineered corn has been engineered to resist pests and herbicides; thus, we have more yield and many people especially in the low class society can afford. A disadvantage, yet is still a debate, is that genetically engineered crops such as corn, has toxic effects to internal organs such as our liver, a vital internal organ.

What is the probability that each of the following pairs of parents will produce the given offspring: 1. AABbCc x aabbcc à AaBbC

ICE Princess25 [194]

Answer:

1) AaBbCc, 50% - 2) AAbbCC, 3,125% - 3) AaBbCc is 12,5%.

Explanation:

1º cross.

Parental) AABbCC x aabbcc

Gametes) ABC AbC ABC AbC ABC AbC ABC AbC

abc abc abc abc abc abc abc abc

Punnet Square) Only filled with the progeny genotype AaBbCc.

ABC AbC ABC AbC ABC AbC ABC AbC

abc AaBbCc --- AaBbCc --- AaBbCc --- AaBbCc ---

F1 Genotype) 32/64 AaBbCc

32/64 AabbCc (shown as the symbol "---" in the

punnet square)

The probability of producing offspring with genotype AaBbCc is 50%.

The rest of the progeny have different genotypes that are represented with the symbol "---" in the punnet square.

The probability of producing offspring with genotype AAbbCC is 3,125%.

What is the difference between conserving energy and the law of conservation of energy

Sphinxa [80]

Hi , energy conservation is the practice of decreasing the quantity of energy used. The conservation of energy states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant.
