How much force is needed to lift something with a mass of 1kg
goblinko [34]

Answer:

Lets be clear, in an inertial frame of reference it will take 1 newton to move 1 kilogram 1 meter in one second(roughly). 1 joule in that newton, 1/speed of light = incremental mass increase( irrelevant) . So, to move 1 kg of mass 1 meter in 0.00000003 seconds would take 300,000,000 joules(fun).

That divided by speed of light again and your 1kg mass is now 2 kg. Now to move 2 kg 1 meter would take more energy than previously. More energy (newtons) the more relativistic mass gained and thus more energy required to move faster. This is why we cant reach the speed of light - infinite energy. ( again irrelevent to the Question).

But in your question you said lift. Lift is a term that I would find on earth, in a gravity well, so moving that same 1kg of mass wouldn't take 1 newton because the gravitational force pulls the mass down, causing a force called weight - this would be 9.8 N x Mass at sea level. So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration.

Note that, gravitational force is one side of the same coin, with acceleration on the other. We talk of gravitation in terms of acceleration, as two masses that are not identical will always fall at the same acceleration. Gravity isn't a force, its a four dimensional field that curves linear paths toward attracting bodies - this is how we are able to orbit objects in space.

How can the random distribution of alleles result in a predictable ratio
jok3333 [9.3K]

Answer:

Let's recall Mendel's law of independent assortment that states, "During the formation of gametes, alleles of genes assort independently into each gamete"

How can the random distribution of alleles result in a predictable ratio?

For example, We have a trait for flower color either yellow or white, and the alleles for the flower color are Y and y. The yellow flower color is a dominant trait, and be expressed if plant has YY or Yy genotype. We cross a plant with genotype Yy with another plant Yy.

P1                                                   Yy   x  Yy

F1                                               YY : Yy: Yy: yy

Phenotype                        Yellow: yellow: yellow: white

Genotypic ratio                 1           :               2       :                 1

Phenotypic ratio                               3         :          1          

So, we see that phenotypic ratio is different from genotypic ratio. Although the distribution of alleles is random but still there are only four possible outcomes for a trait. Hence, we can predict the phenotypic and genotypic ratio of offspring by drawing a punnet square or gamete formation.

Nearly all cells found in multicellular organisms have similar needs. As a result, most organisms have developed similar _______
melomori [17]
This statement is mostly false. While all organisms do share basic needs to sustain life, there is a wide variety of strategies employed to meet these needs. For example, while most plants receive nutrients from soil, some live in soils which do not fully meet their needs. Such plants sometimes kill and use animals in order to meet these needs (i.e. venus flytrap) or partner with bacteria that produce some of the nutrients they need (i.e legumes).
