Answer:

Digestive system and Circulatory system

Explanation:

The Digestive system has the stomach, small and large intestine- these are all responsible for breaking down food into smaller pieces and on the other hand the circulatory system helps to distribute the broken food around the body for necessary absorption by the body cell.

Explain El Niño, how it’s identified, and it’s potential negative impacts.
nadya68 [22]

I know this is a lot :This might not have negative impacts:

El Niño is a natural phenomenon experienced in the equatorial Pacific which causes temporary alterations in the world climate. It is normally characterized by complex and abnormally warm ocean temperatures in the Pacific Ocean in the area near the equator which results in global weather events and sea-surface temperature changes.

In practical sense, the ocean surface around the equator region warms up by small degrees Celsius along with very heavy thunderstorms. The small rise in temperatures is influenced by change in the normal wind direction. Scientist also prevails that the temperature increases may be intensified by the effects of greenhouse gases and consequent global warming. This small difference in temperature increase has a substantial impact on the world’s climate.

In normal conditions, the wind blow from the east to the west along the equator in the Pacific. These are the trade winds which blow towards the west along the equator. This results in the piling of water in the western side of the Pacific to a sea surface area of up to 18 inches high.

In the eastern side, deeper water (which is cooler compared to the sun-heated warm surface water) gets pulled up from beneath to substitute the water pushed to the west. So, the normal difference in temperature across the equatorial Pacific is cold water (about 22 degrees Celsius) in the east and warm water (about 30 degrees Celsius) in the west.

In El Niño conditions, the winds propelling the water get weaker and as an outcome, some of the warm water collected in the west is heavily drawn towards the east. At the same time, not so much cold water is pulled up from beneath. Accordingly, these elements make the water in the pacific warmer which results in El Niño events.

Drastic Effects of El Niño

Effect on aquatic species and sea birds

In normal situations, the ocean water carry nutrients that lie beneath the ocean to the top thereby allowing the fish species living in the upper waters to feed on the planktons that rely on these nutrients. Seaweeds also rely on cool and nutrient-rich water for survival and growth. An El Niño lessens the upwelling of cold water and the uplift of nutrients from the bottom of the ocean.

As a result, fish either migrate to other regions or die during an El Niño because they lack adequate food for growth and survival. When fish have migrated or reduced in number, other aquatic creatures namely the sea birds and seals that feed on the fish are also affected. Off the coast of California, the aquatic populations such as fish, seals, sea lions, and sea birds are normally affected and deaths are registered during El Niño events.

What are the space limitations for human population growth?
Nonamiya [84]
If you’re talking about too many people I’m guessing the limitation factors would be lack of resources and that would include lack of food and space.

Why isn't the longest day of the year the hottest day of the year?
Pachacha [2.7K]
The longest day of the year isn't the hottest day of the year because the phenomenon of the hottest weather following the summer solstice by a month or two is called the lag of seasons.

An old alternative hypothesis for the evolution of infanticide was that parents killed offspring (including their own) when food
Alika [10]

Answer:

On the basis of gender preference.

Explanation:

In the modern view of adaptation, the main cause of infanticide is not the food  but the gender preference. In many societies, people killed their infant when they knew that the infant is a girl. They thought that having a girl is curse or shameful thing so they kill the infant. These type of people wants male baby or prefer male child so that's why they kill the infants. In the ancient times, infants were killed that were abnormal or having any defects but today it happen due to gender preference.
