Answer:
A. Algae growth is high
Explanation:
Substances that contains high concentration of nitrates, phosphates etc add nutrients to the water body. This is because organisms like ALGAE consider these compounds nutrients needed for their growth and development. The process whereby these nutrients becomes excessive in a water body is referred to as EUTROPHICATION.
Eutrophication of a water body i.e excessive nutrients like nitrates in a water body like the North Carolina waters being described in this question will lead to rapid and excessive growth of algal species. This increase in algal growth can cause the water body to be low in oxygen content and ultimately become inhabitable by living organisms.

Answer : Music is read differently in the brain than
nonmusical tones and is connected to many different areas of the brain. Learning music
relegates a larger part of the brain to recognizing and interpreting music. Listening to
music has also been found to have an effect on learning.
Answer:
The heart would listen to music with a nice rhythm as it beats to the song.

After studying weather, Beto bought a simple weather station and put it up in his yard. He was especially interested in wind and how it forms around Earth. Choose the correct words or phrases to complete the sentences.
Incomplete question. The remaining part reads;
Choose the correct words or phrases to complete the sentences.
Global winds occur due to
1. Choose...
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
over a large area and this forms
2. Choose...
a. solar currents
b. convection currents
c. sea breezes
d. uneven heating
caused by cool and warm air.
Answer:
1. d. uneven heating
2. b. convection currents
Explanation:
1. What Beto should know is that as the earth moves and rotates around the sun, some parts of the Earth receive more sunlight and others less, which then leads to uneven heating over a large area of the earth.
2. This uneven heat then forms a convection current containing varying patterns of air spreading to various parts of the globe.

3.2 g of a gas at occupy the same volume as 0.6266 g of CH4 at 17°C at constant pressure
Find the molecular mass of the gas.
Assuming gas temperature = 25, 3.2 g of a gas at 25°C occupy the same volume as 0.6266 g of CH4 at 17°C at constant pressure
The molecular mass of the gas : 842.1 g/mol
Find the molecular mass of the gas.Further explanationGiven
3.2 g of gas
0.6266 g of CH4
Required
the molecular mass of the gas
Solution
Because V, P, and R are the same, from ideal gas law :
PV=nRT
n₁T₁=n₂T₂
n₂=moles CH₄= 0.6266 : 16 g/mol = 0.0392
T₁=25+273=298 K
T₂=17+273=290 K
mol of gas :
[tex]\tt n_1=\dfrac{n_2.T_2}{T_1}=\dfrac{0.0392\times 290}{298}=0.038[/tex]
molecular mass :
[tex]\tt M=\dfrac{3.2}{0.038}=842.1[/tex]
explain what a convection current is?
who ever sees this I hope you have a wonderful day!
Answer:
Convection currents are flowing fluid that is moving because there is a temperature or density difference within the material.
Because particles within a solid are fixed in place, convection currents are seen only in gases and liquids. A temperature difference leads to an energy transfer from an area of higher energy to one of lower energy.

How many molecules are equal to 3.52 moles of oxygen difluoride?
Answer:
3.52 moles are equal to 21.2 ×10²³ molecules
Explanation:
Given data:
Number of moles of oxygen fluoride = 3.52 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
3.52 mol ×6.022×10²³ molecules / 1 mol
21.2 ×10²³ molecules
Thus, 3.52 moles are equal to 21.2 ×10²³ molecules .

Answer: Stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination. The main flower parts are the male part called the stamen and the female part called the pistil. The stamen has two parts: anthers and filaments. The anthers carry the pollen. The four main parts of a flower are the petals, sepals, stamen, and carpel (sometimes known as a pistil). If a flower has all four of these key parts, it is considered to be a complete flower.
