_____ allow materials to be exchanged between the blood and tissues, _____ carry blood towards the heart, and _____ carry blood
likoan [24]

Capillaries; veins; arteries

Capillaries allow materials to be exchanged between the blood and tissues, veins carry blood towards the heart, and arteries carry blood away from the heart.

Capillaries are small blood vessels through which molecules such as oxygen and glucose enter the cells.  

Veins are tubes or blood vessels that transport blood toward the heart. Veins mostly transport deoxygenated blood towards the heart except the pulmonary and umbilical veins, which transports oxygenated blood toward heart.

Arteries are blood vessels that transport blood away from the heart to other parts of the body. Arteries have elastic walls and they are stronger and thicker than veins.

A certain lake has a volume of about 480 m³. If the total population of freshwater shrimp in the lake is 600 million, what is th
emmainna [20.7K]

Answer:

1,250,000 shrimps per m³

Explanation:

Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;

Population density = population (N)/volume

According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;

Population density of the lake = population of shrimps ÷ volume of lake

Population density = 600,000,000 ÷ 480

Population density = 1,250,000 shrimps per m³

What caused an increase in phosphorus pollution in Florida waters?
Hatshy [7]
The correct answer is A.
Water runoffs usually carry nutrients especially fertilizers from off the landscape and washed them into the wetlands and other water bodies. Phosphorus is a common ingredient that is present in all fertilizers. Phosphorus acts as a pollutant in these water bodies and put the organisms living in the water bodies at risk. High concentration of phosphorus causes rapid growth of plants in the wetlands and lead to depletion of oxygen leading to the death of organisms living in the wetlands.
Due to this occurrence, the Florida government has taken steps and enact several laws to ensure that the phosphorus pollution is arrested in order to preserve the wetlands.

F(x) = x^2-5<br> g(x) = 4x - 4<br> Find (f-g) (5)
7nadin3 [17]

Answer

(f-g) (5) = 4

Explanation:

f(x) = x^2-5

g(x) = 4x - 4

Find (f-g) (5)

= (x^2-5)  - (4x - 4 )

= (5^2-5)  - (4(5) - 4 )

= 20 - 16

= 4
