Explain some of the ocean’s other benefits besides supplying us with water.
mojhsa [17]
The ocean moderates the Earth's climate. Most solar radiation occurs at the Equator, whereas the poles receive little radiation. The ocean<span> transport warm water from the Equator toward the poles and cold water from the poles back to the Equator. The oceans provide a habitat for much of the marine life exploited by humans, such as harvested fish. The oceans act as a massive carbon sink, as phytoplankton absorb carbon from the atmosphere through photosynthesis. The ocean also provides a medium for large scale transportation of goods through shipping. It is unlikely that vehicles as large as container ships could ever be transported over land.</span>

In which sections or section of the kidney is the urine formed? what section of the kidney collects the urine? how does the urin
torisob [31]

In which sections or section of the kidney is the urine formed? 

The final product of filtration, reabsorption, and secretion which is the urine is primarily formed in the renal medulla although the formation of the urine starts with the filtration of blood in the glomerulus then along the proximal tubules, descending and ascending loop of Henle, distal tubules, and collecting ducts. 


What section of the kidney collects the urine? 

The renal pelvis is the main section of the kidney that collects the urine. The renal pelvis arises from the confluence of the collecting ducts forming the renal papilla then the minor calyx and the major calyx and ultimately to the renal pelvis to be transported to the urinary bladder through the ureters.


How does the urine move from the kidney out of the body? 

The urine will be collected in the renal pelvis. With the urine collected in the renal pelvis, the urine moves from the renal pelvis to the urinary bladder through the ureters and will be stored in the urinary bladder. When there is an urge to urinate, the urinary bladder contracts and the urethral sphincter relaxes that allows passage of the urine from the bladder out of the body through the urethra.


In which main regions of the kidney are the glomerulus and the Bowman's capsule located? 

The glomerulus and the Bowman’s capsule are part of the renal cortex. These organs are responsible for the filtration of the blood from the afferent arteriole. The glomerulus and the Bowman’s capsule are not synonymous but rather the glomerulus comes from the afferent arteriole and the Bowman’s capsule functions as a filtration membrane. Together, they are called the renal corpuscle.


In which main regions of the kidney are the collecting ducts and the loop of Henle located?

The collecting ducts are located in the renal medulla whereas the loop of Henle are partly in the medulla, depending on the type of nephron. In superficial cortical nephrons, the dips only up to the outer medulla while in the juxtamedullary nephrons, the glomerulus is near the corticomedullary border wherein more parts of the loop of Henle is in the medulla.

How do auroras form??
Nimfa-mama [501]
<span>The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions result in countless little bursts of light, called photons, which make up the aurora.</span>

do members of the same phylum share more characteristics than members of the same class?​ Explain why or why not.
SVEN [57.7K]

Answer: No, they don't.

Explanation:

In the taxonomic rank (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species-- in that order) because phylum comes before class, it means it covers a broader spectrum of organisms. So, the traits are less specific. As you narrow it down, the members of the rank will share more and more traits in common.

Here is an example:

Humans are a member of the phylum chordata. All members of phylum chordata share the same 5 traits at some point in their lifetime. (Some only show the traits when they are embryos/larvae). These 5 characteristics share a tail, a notochord, a single, hollow nerve cord, pharyngeal slits, and an endostyle (thyroid).

So, now that we've established that humans are from phylum chordata, we can narrow it down to what class they are in. Humans are in the class mammalia, meaning they are mammals. All mammals not only share those 5 characteristics of phylum chordata, but they also share characteristics that unite them with each other. They all have hair, mammary glands in females, and are endothermic.

So, while members of the phylum chordata share at least 5 traits, members of the class mammalia share at least 8.

I hope that makes sense!
