Answer:
1 is the smaller cell and 100 is the larger cell
Answer: The given statement is true.
Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
General equation of ionization energy is given by:
- If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.
- And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.
Hence, the given statement is true.
Answer:
a. all tall plants
Explanation:
The gene that makes the plant tall is dominant
Answer: 25%
Explanation:
First find the trait that describes the pea shape because that’s what you’re being asked to find. In this case, pea shape is either wrinkled (s) or smooth (S). If the two plants that are crossed are both heterozygous, that means they each have one dominant allele and one recessive allele, which would like this: Ss. By putting both of the Ss genotypes (one Ss for one parent at the top of the board and the other Ss for the second parent down the side of the board) around the punnet square, you get: Ss x Ss= SS, Ss, Ss, ss. You are then asked to find the percent of wrinkles peas, which can only be shown when both alleles are recessive. By looking at the punnet square you can see that that only happens 1/4 times. When you turn that into a percent you get 25% of the plants that have wrinkled peas.
Answer:
Explanation:
'There used to be a number of theories about how the Moon was made and it was one of the aims of the Apollo program to figure out how we got to have our Moon,' says Sara.
Prior to the Apollo mission research there were three theories about how the Moon formed.
Capture theory suggests that the Moon was a wandering body (like an asteroid) that formed elsewhere in the solar system and was captured by Earth's gravity as it passed nearby. In contrast, accretion theory suggested that the Moon was created along with Earth at its formation. Finally, according to the fission scenario, Earth had been spinning so fast that some material broke away and began to orbit the planet.
What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.
