Question 2 (0.5 points) In the Northern Hemisphere, choose ALL that apply Summer solstice occurs when the Earth's North Pole is tilted toward the sun, longest day. Summer solstice occurs when the Earth's North Pole is tilted away from the sun shortest day. Winter solstice occurs when the Earth's North Pole is tilted away from the sun. shortest day. Winter solstice occurs when the Earth's North Pole is tilted toward the sun. longest day.
Answer:
In North America, around June 21, Earth tilts on its axis toward the sun, which is Summer Solstice and when the Northern Hemisphere has the most daylight of any time of year. Winter solstice the Northern Hemisphere tilts the farthest away from the sun and when we have the least amount of daylight of any time of the year.
Explanation:
As Earth revolves around the Sun, it rotates on its axis. Sometimes Earth tilts toward the Sun which is when Summer occurs. In the Winter Earth tilts away from the Sun.
In the northern hemisphere summer solstice occurs when the earth north pole is tilted towards the sun, longest day and winter solstice when the earth north pole is tilted away from the sun shortest day . Thus both the option a and c are correct.
What are solstices?Solstices occurs when earth is pointed directly towards the sun. This incident happens twice a year during earth's orbit.
On June 21 the north pole is tilted 23.5 degree towards sun and the northern hemisphere experience summer solstices which is known as longest day of the northern hemisphere year.
On 21 June, the southern hemisphere is tilted 23.5 degree away from sun and southern regions of earth experience the shortest day of the year which is known as winter solstices.
Therefore In the northern hemisphere summer solstice occurs when the earth north pole is tilted towards the sun, longest day and winter solstice when the earth north pole is tilted away from the sun shortest day . Thus both the option a and c are correct.

15. What is the function of the electrons as they move along the electron transport chain?
Answer:
The direct purpose of moving electrons down the electron transport chain is to pump protons (hydrogen ions) into the intermembrane space. This creates a chemiosmotic gradient that the cell uses to generate ATP by selectively allowing hydrogen ions to move back into the mitochondrial matrix.

Answer:
Living organisms that are made up of cells that have nucleus are called EUKARYOTES
Explanation:
Living organisms are grouped into two according to the composition of their cell components. These include:
--> The PROKARYOTES: these organisms possess a very simple cell structure with no definite nucleus. Example of such organisms include the eubacteria (that is, 'true' bacteria), archaebacteria ( which is also a type of bacteria) and blue green algae.
--> The EUKARYOTES: these organisms possess a complex cell structure with a well defined nucleus. The nucleus is found enclosed within a nuclear membrane. Hereditary materials are located within the nucleus and the cell has other components known as the cell organelles. These organelles include the mitochondria, Golgi apparatus, Endoplasmic reticulum, Ribosome, lysosomes. Example of eukaryotes are the animals, plants, fungi, and protists.
Therefore, Living organisms that are made up of cells that have nucleus are called EUKARYOTES

Some cities hang their traffic
lights from left to right, rather
than from top to bottom.
Explain why this might cause a
problem for a driver with red-green perception deficiency.
Answer:
The angle and location
Explanation:
There are some who can't perceive the order of red and green together. Having it angled up and down is safer because you know out of common sense that red is on top and green is on the bottom. Having it sideways makes the light elevated on the same level, deceiving the eye better.
Some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.
What role do traffic lights play?Traffic lights typically have three colors, such as red, yellow, and green, which are arranged in a vertical orientation in most cities, but in some cities, traffic lights are hung in a horizontal or left-to-right orientation, which can be challenging for those who have red-green color blindness. The traffic lights are there to prevent accidents.
Hence, some cities hang their traffic lights from left to right rather than from top to bottom, and this causes problems for drivers, as the left-to-right orientation of traffic lights can pose a problem for drivers with red-green perception deficiencies.
