Spring balances or spring scales calculate weight that is the product of mass into gravity (9.807 m/s2) on the force on a spring, whereas a balance or pair of scales using a balance beam compares masses by balancing the weight due to the mass of an object against the weight of one or more known masses.
Question: A scientist is studying fruit fly wings. Straight wings are dominant, and curly wings are recessive. Which statement correctly describes the F1 generation if a straight-winged parent is crossed with a curly-winged parent and if both parents are true breeding?
Answer choices:
1. The offspring will have two genes for straight wings.
2. The offspring will produce only gametes that have genes for curly wings.
3. The offspring will have one allele for straight wings and one allele for curly wings.
4. The offspring will have only one kind of allele for the gene that determines wing type.
Correct answer: The offspring will have one allele for straight wings and one allele for curly wings.
AA + aa = Aa

Enzymes split the DNA molecule into two rails and then transport corresponding nitrogen bases to each rail. I think this is the answer
Its based on radiometric age-dating of meteorites material and is consistent with the radiometric ages of the oldest known terrestrial and other lunar samples
Answer:
Scientists consider phylogenetic trees to be a hypothesis of the evolutionary past since one cannot go back to confirm the proposed relationships.
Explanation:
Basically it is a hypothesis from before hypothesis actually were called hypothesis
