PlLEASE HELP ME> I NEED THIS ANSWER RIGHT NOW. The bass and crayfish likely “died off” because the rapid growth of the algae eventually caused the level of dissolved oxygen to decline to a point that these oxygen-dependent organisms could no longer survive. How would you modify this investigation of the pond organisms to determine if the algal bloom really was the cause of the bass and crayfish die-offs?
Answer:
bacteria blooms and decreased underwater photosynthesis causes hypoxia, killing the fish. c. floating algae die, increasing sunlight penetration and heating the water. ... This has led to algal blooms in the pond which periodically reduce the amount of dissolved oxygen available in the water

describe each step of endocytosis
Explanation:
The Basic Steps of Endocytosis
The plasma membrane folds inward (invaginates) forming a cavity that fills with extracellular fluid, dissolved molecules, food particles, foreign matter, pathogens, or other substances.
The plasma membrane folds back on itself until the ends of the in-folded membrane meet. This traps the fluid inside the vesicle. In some cells, long channels also form extending from the membrane deep into the cytoplasm.
The vesicle is pinched off from the membrane as the ends of the in-folded membrane fuse together. The internalized vesicle is then processed by the cell.

The fifth grade craft club is making aprone to sell
Each apron take 1.25 yards of fabrie that costs $3
per yard and 4.5 yards of trim that costs $2 per yard,
What does it cost the club to make one apren? If the
club wants to make $1.75 profit on each apron how
much should they charge per apron?
Answer:
Each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.
Explanation:
Since the fifth grade craft club is making aprons to sell, and each apron take 1.25 yards of fabric that costs $ 3 per yard and 4.5 yards of trim that costs $ 2 per yard, to determine what does it cost the club to make one apron, and, if the club wants to make $ 1.75 profit on each apron, how much should they charge per apron, the following calculations must be performed:
1 apron = 1.25 yards of fabric at $ 3 per yard and 4.5 yards of trim at $ 2 per yard
1.25 x 3 + 4.5 x 2 = X
3.75 + 9 = X
12.75 = X
12.75 + 1.75 = 14.50
Therefore, each apron costs $ 12.75, and to make a profit of $ 1.75 they should be sold for $ 14.50.

A) skin cancer
B) cataracts
C) obesity
D) respiratory illneses
Answer:
obesity
Explanation:
The following that is not a health risk associated with ozone is obesity. The correct option is C.
What is ozone?Ozone is a trioxygen inorganic molecule that is of pale blue color. The ozone layer is present in the stratosphere of the atmosphere. It absorbs the UV rays coming from the sun. Thus, it is a protective layer that saves from UV rays.
UV rays are harmful rays that affect health. It creates skin problems and many other health problems. So the ozone layer protects us from UC radiation, it acts as a shield.
Obesity is a condition in which the body becomes fat. It happens with the accumulation of fat in the body. This does not occur with UV rays. It occurs due to food. So this will not be a health risk associated with ozone.
Thus, the correct option is C. obesity.

Maintaining homeostasis keeps the internal environment in the body functioning properly. Many organ systems work together and maintain energy homeostasis. The digestive system is concerned with processing the food that we take in to provide essential nutrients to the rest of the body. Which of these body systems works most directly with the digestive system in the absorption of nutrients?
A) urinary system
B) endocrine system
C) respiratory system
D) cardiovascular system
Answer:
D
Explanation:
However, the organ systems also work together to help the body maintain homeostasis. For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance. The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure.
