Answer:
If you flip two coins, the probability that both will come up heads is 25%.
Explanation:
Probability is the chance that one or more events occur. In this case, the individual event is the coin flip. When you flip a coin, the probability that will come up heads is 0.5 or 50% because you have two choices with the same probability (50% heads, and 50% tails).
However, the question is related to multiple events. The events can be independent (the result of one event does not affect the result of the other) or dependent (the result of one event affects the result of the other). In this, because you are flipping two coins, events are independent; therefore the probability of each event is the same (0.5 or 50%)
To calculate it:
Probability of heads1 x Probability of heads2 = Probability of 2 head
0.5 x 0.5 = 0.25
to convert into a percentage:
(0.25/1) x 100 = 25%
Answer:
The correct answers are "A magnetic field is the area around a magnet where a force is exerted on certain objects", "Magnetic field lines spread out of the north end of the magnet" and "Magnetic fields are three-dimensional and resemble a bubble".
Explanation:
Three statements that define a magnetic field are:
1. "A magnetic field is the area around a magnet where a force is exerted on certain objects". Magnetic field force is driven by moving electric charges and the objects that are susceptible to the forces are known as electromagnetic objects.
2."Magnetic field lines spread out of the north end of the magnet". Magnetic fields are taken to be outward from the North pole to the South Pole. This direction takes place on Earth as well, because Earth function as a giant magnet.
3. "Magnetic fields are three-dimensional and resemble a bubble". Magnetic field forces are driven following a bubble like configuration and affects the objects upon this configuration.

Explanation:
Sporophyte to spores
Male gametophyte to spores
Female gametophyte to zygote
Answer: The correct answer is-
A sporophyte can be described as the multicellular, diploid phase in the life cycle of plants and alga.
It is the dominant phase in higher plants ( such as angiosperms and gymnosperms) and undergoes alternation of generation with a haploid, gametophyte phase.
Sporophyte produces haploid spores ( having half the number of chromosome as their diploid parent cell) by a process of cell division called meiosis ( also termed as reductional cell division)
The spores fuse to form a dipolid zygote that undergoes mitotic division to produce the sporophyte again.
On the contrary, male and female gametophyte are already haploid.
Thus, second option is the right answer.
