59 minutes

Explanation:

There is 1 hour (equivalent to 60 minutes) between 11.00pm and midnight.

Using the formulae; P <em>(future</em>) = P <em>(present)</em> * (1 + <em>i</em>)ⁿ where

P <em>(Future) </em>= Future Population

P <em>(Present)</em> = Present Population

<em>i</em> = Growth Rate

n = Number of generations

The bottle was full after 60 minutes and it was filed by the following number of bacteria

P<em>(future) </em>= 1 * (1+1)⁶⁰ = 1,152,921,504,606,846,976

A half-filled bottle would have half the number = 576,460,752,303,423,488

Using the same formulae to find after how many generations do we get to this number;

576,460,752,303,423,488 = 1 * (1+1)ⁿ

(576,460,752,303,423,488) / 1 = (2)ⁿ

n = log₂ (576,460,752,303,423,488)

n = 59

This means the bottle got full at 59 minutes.

Please help me it's easy guys

Answer:

D

Explanation:

The functions of nucleic acids(DNA AND RNA) have to do with the storage and expression of genetic information. DNA encodes the information of the cell necessary to make proteins while the RNA participate in protein synthesis.

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.

Describe how the environment (predation, shelter, wind, access to water) might affect a population/ species?

Helga [31]

Answer: The environment might affect the population, because there might be more predators in one area compared to another

Atoms that have gained or lost electrons are called

Anna71 [15]

Answer:

Atoms have the same number of electrons and protons and hence have net 0 charge. When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost (or donated), the resulting ion is called cation. When electrons are gained, the resulting ion is called an anion.
