Answer:
Sexual reproduction can be described as the method of reproduction in which the offsprings produced will have half the chromosomes as compared to the parent cell. The other half of the chromosomes to make a complete set would arise from the other parent. In this way, the offspring produced will carry half of the chromosomes from the female parent and half from the male parent.
Crossing over and independent assortment are two phenomenons of meiosis due to which genetic diversity occurs and the offsprings born are not exactly similar to the parent cell.
Answer: The four cells that are produced by meiosis has only one of each chromosome. One of these four cells from one parent combines with another from the other parent to produce the offspring. An offspring gets half its chromosomes from each parent. But the exact combination of chromosomes it gets from each parent is random. So, each offspring ends up with a unique set of genes different from its parents and other offspring.
Answer:
Protons and neutrons
Explanation:
it confines quarks into hadron particles such as the proton and neutron. ... On a larger scale (about 1 to 3 fm), it is the force (carried by mesons) that binds protons and neutrons (nucleons) together to form the nucleus of an atom.
Answer:
protons and neutrons
Explanation:
they are the two sides of the atom that are around the nucleus.

The dark-colored mutation could be beneficial in a polluted area because this phenotype may confer an adaptive advantage.
A mutation is any alteration in the nucleotide DNA sequence (genome) of an organism.
Mutation can be beneficial, deleterious, or neutral depending on the environmental conditions in which the individual lives.
In this case, the dark-colored mutation could be beneficial for an insect living in a polluted area because bright-colored phenotypes make the moth very conspicuous to visual predators.
In consequence, dark-colored insects have more chances to survive and reproduce (i.e., they have an adaptive advantage), thereby these insects have more chances of passing this mutation to the next generation.
In conclusion, the dark-colored mutation could be beneficial in a polluted area because this phenotype may confer an adaptive advantage.

Answer : The correct option is (d).
Explanation:
Hydrosphere : It is portion or surface covered by water or fluid on the Earth. Such as : oceans, lakes , lakes, clouds etc.
Geosphere: It is a solid portion of the Earth system which includes substance found on interior side of the Earth like: rocks,minerals landforms etc. Basically it provides shape to outermost layer of the earth.
Biosphere: Regions of surface, atmosphere and hydrosphere of the Earth occupied by living organisms is known as biosphere.
Chronospere: It is mass teleportation device which can move object through space and time.
So, from all the above options chronosphere is not a part of the earth system. Hence correct option is (d).
