You are at the zoo and watching a lion chew on some meat. You begin to taunt the lion since he is behind the glass and cannot get to you. He
charges the glass and breaks through. Your adrenaline kicks in and you take off running. What system is repressed during your escape?

Answers

Answer:

The parasympathetic nervous system is repressed during your escape.

Explanation:        

In the exposed example, during your escape from the lion, the sympathetic nervous system (SNS) and the hypothalamic-pituitary-adrenal (HPA) system are responsible for your body response. They send signals and release adrenaline and noradrenaline to increase your heart biting frequency, and blood pressure, stimulating your respiration and dilating your respiratory tracts.

Once you manage to escape from the lion, and the threat factor is over, the body gets back to normality. At this point, the parasympathetic nervous system is activated. Your body activities become normal again. Your arterial pressure, respiratory frequency,  and cardiac frequency get reduced to their normal conditions. You are relaxed and at rest.

When the parasympathetic system is activated, the sympathetic nervous system is not, as they perform in opposite ways.

Where do tidal bulges form during the New and Full moons?

Answers

Answer:

hope it helps..

Explanation:

High and low tides are caused by the Moon. The Moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the Moon and the side farthest from the Moon. These bulges of water are high tides.

Answer:

D. Emigration

Explanation:

The answer is D. because the actual definition for emigration is: "The act of leaving one's own country to settle permanently in another; moving abroad." The definitions between immigration and emigration are very similar but the actual definition for immigration is: "The action of coming to live permanently in a foreign country." so I would stick with D.

Which is denser, 50 mL of water or 500 mL of water?

Answers

Answer:

50mL

Explanation:

Density is inversely proportional to volume.

This implies that, for the same mass of water, the higher the volume, the less dense it is.

By comparison 500ml is greater than 50ml

Going by the above analysis, 50ml will be less dense than 500ml because it is smaller.

Why did life first occur in the oceans and not on Earth’s surface?

Answers

Answer:

I think because many more bacteria and cells and etc were first like created in the water, they they developed and made bigger and bigger living organisms

Answer:

Because God decided that he was gonna make animals first and he started with the ocean and then land and sky. He then made Adam to take care of all of the animals. But saw that he was lonely and made Eve with one of his ribs. He then put them in the garden of Eden with a tree that was forbidden to eat from. The tree of knowledge of the good and evil. One day eve was walking by the tree when a serpant asked her why they didn't eat from it. She replied by saying that God asked them to not eat from that tree. The serpant told Eve that God just doesn't want them to be knowledgeable like him. She took a bite of the apple and then gave some to Adam. They then realized that they were naked and made clothing from animal skin. This was what created sin. They tried to hide from God but he already knew and he banished them from the garden with angels and a fire sword at the enterance. He went to the serpant and cursed him for telling Eve to eat from the tree. Adam and Eve went on their way and had 2 boys. Cane and Abel.

All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum.
Which of the following best describes a process that occurs within the Golgi complex?

Answers

Answer: Enzymatic modification of newly synthesized integral membrane proteins

Explanation: got it right for AP Bio.

The correct answer that describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Once protein is synthesized, they undergo folding and repackaging within the endoplasmic reticulum before they are transported to the Golgi apparatus/complex.

Within the Golgi complex, the protein is modified enzymatically and encased in vesicles. It is then transported to the cell membrane where they are utilized as integral protein.

So, basically, the statement that best describes the process that occurs within the Golgi complex is the enzymatic modification of newly synthesized integral membrane proteins.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Why is oceanic crust younger than continental crust?

Answers

Answer:What is the best explanation for why oceanic crust is subducted by continental crust?

The continental crust is also less dense than oceanic crust, although it is considerably thicker. As a consequence of the density difference, when active margins of continental crust meet oceanic crust in subduction zones, the oceanic crust is typically subducted back into the mantle.

Explanation:Why oceanic crust is younger than Continental?

Through mantle convection, the rich minerals of the mantle may be ultimately “recycled” as they surface as crust-making lava at mid-ocean ridges and volcanoes. Largely due to subduction, oceanic crust is much, much younger than continental crustWhy is the theory of plate tectonics so important to geologists?
