Answer:
During summer in the northern hemisphere, the days are longer than winter.
Explanation:
Earth tilting is the main cause of formation of seasons. Summer season occurs when the earth tilt towards the sun. The earth tilt about 23.5 degrees toward the Sun. Summer occurs when the northern hemisphere tilt toward the Sun because sun rays directly hit that area which increases the temperature of that area and those areas experience winter which do not recieves direct radiation of sun.
"Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant."
The right answer is a.anatomy involves symmetry.
In the anatomy of multicellular animals with bilateral symmetry (which form the subregion of bilateria), there are many even organs, that is to say composed of two symmetrical halves, generally positioned on both sides of the median plane. This is the case, for example the human brain that includes two hemispheres, two amygdalas and two hyppocampus, a left and a right.

But for the male, they only have one X chromosome and will express any recessive alleles on that chromosome
