Which would result in the most diverse offspring?
Bees bringing pollen from the flower of one plant to the flower of another plant.
A bacteria cell reproducing through asexual reproduction.
An orchid with a flower structure that can pollinate itself.
Planting a cutting from a potato to grow a new potato plant.
Answer:
B
Explanation:its the best answer
The most diverse offspring is produced when bees bringing pollen from the flower of one plant to the flower of another plant where, the new flower made will show a characteristic of both plants?
What is pollination?Pollination is the process of transferring pollen grains from the anther of the flower to the female stigma portion. This is a mechanism to create offsprings of the plants.
Pollination can be occurred through various agents such as insects, wind, water etc. Some plants contains both male and female flower within it and those are self pollinating.
Bees and butterflies are the main pollinating agents for plants. When they bring the pollen grains from one plant to another plant's flower the resulting offspring will have diverse properties which are mix of each plants.

What is the frequency of radiation whose wavelength is 2.25 X 10^-5cm?
Answer:
1.25 x 10^15Hz
Explanation:
c = frequency x wavelength
c is the speed of light, which is equal to 3.00 x 10^8 m / s
frequency = c /wavelength
= (3.00 x 10^8m /s) / (2.40 x 10^-5 cm x 1 m /100cm)
= (3.00 x 10^8 m/s) / 2.40 x 10^-7m
= 1.25 x 10^15/s 1 / s = 1Hz
So, the Frequency = 1.25 x 10^15Hz

The principle of conservation of mass is satisfied in a chemical equation when
The law of conservation of mass is also called the law of conservation of matter. When a chemical equation is balanced then it obey the law of conservation of mass.
What is law of conservation of mass?The law of conservation of mass was postulated by the scientist A. Lavoisier. It states that in a chemical reaction, the total mass of the products is equal to the total mass of the reactants.
In a balanced chemical equation, the mass of the reactants and products on either side of the equation will be equal. In other words, matter is neither created nor destroyed in a chemical reaction.
A balanced chemical equation also contains the same number of atoms of reactants and products on both sides. An equation is balanced by adding stoichiometric coefficients to the reactants and products.
Thus it obey the law of conservation of mass.

Before J.J. Thomson began gathering evidence about electrons in 1897, what did scientists know about atoms?
Answer: Scientists generally thought atoms were the smallest particles that could not be broken down any further.
Explanation: Trust me
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Scientists generally thought atoms were the smallest particles that could not be broken down any further.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.
Before J.J. Thomson began gathering evidence about electrons in 1897. Scientists generally thought atoms were the smallest particles that could not be broken down any further.

What happens when the North Pole of one bar magnet is near the south Pole of another bar magnet?
A.Both attraction and repulsion
B.neither attraction nor repulsion
C.attraction
D.repulsion
When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. So, the correct option is C, attraction. This is because opposite magnetic poles attract each other, while like magnetic poles repel each other.
What is a magnetic field?A magnetic field is a region in space where a magnetic force can be detected. It is created by the movement of charged particles, such as electrons, protons, and ions. A magnetic field can be produced by a magnet, an electric current, or a changing electric field.
When the North Pole of one bar magnet is near the South Pole of another bar magnet, they will attract each other. This is because the magnetic field lines of the two magnets interact in such a way that they try to align with each other. Since opposite magnetic poles attract each other, the North Pole of one magnet will be attracted to the South Pole of the other magnet.
The magnetic force between the two magnets depends on the strength of the magnetic field and the distance between the magnets. The closer the magnets are, the stronger the magnetic force will be.
Therefore option C, attraction is correct.

11. Real World Chemistry - Explain why bottled gas containers are equipped with a relief valve?
Answer:
When mensuration volume of air within the flask at the primary temperature, a volume of 250mil was recorded, referred to as V1. The temperature of the air within the flask in boiling water was recorded as 99ᵒC, referred to as T2. so as to seek out the right calculations, 99ᵒC must be born-again to Kelvin by adding 273.
the primary temperature in Kelvin is 372K. the worth of V1/T1, may be found by swing 250/372. This involves a complete of zero.67. the quantity of the air within the flask of the second temperature was 177 mil, referred to as V2.
The temperature of the air within the cooled flask is 7ᵒC, referred to as T2. 7ᵒC must be born-again to Kelvin by adding 273 that involves a final total of 280K. the worth of V2/T2, found by swing 177/280 involves a complete of zero.63.
The close to equality in numbers may be attributed to Charles Law. Charles Law states that “as the temperature will increase, thus will the quantity of a gas sample once the pressure is command constant”.
The results of V1/T1 and V2/T2 were terribly on the brink of one another. this can be because of the very fact that this experiment was worn out as a closed system. In Charles Law, if there's a closed system the 2 ratios ought to have equal numbers. {this is|this is often|this may be} why it can be expected for the magnitude relation numbers to be terribly equal.
