Different seasons arise as the Earth revolves around the Sun because the Earth's axis is tilted. When the Northern Hemisphere is
tilted towards the Sun what seasons will the two hemispheres be experiencina?

When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer. At the same time, the Southern Hemisphere is tilted away from the sun and experiencing winter

The Northern Hemisphere will be in summer, and the Southern Hemisphere will be in winter.

Explanation:

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
