Answer:
Prized fish, such as swordfish, cod and tuna, have undergone dramatic declines. In the Great Lakes, overfishing has caused whitefish, walleye, and sturgeon populations to decline. Beyond their role in the food supply, freshwater and marine fish are also trapped for the aquarium trade and fished for sport.

B. False
Answer:
A
Explanation:
Overfishing decreases the population of trout living in a river.
What would also decline because of the decreasing number of trout?
A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.
Identify methods used to control pathogens
Answer:
There are the physical and chemical method
Explanation:
Physical control includes such methods of control as high or low temperature, desiccation, osmotic pressure, radiation, and filtration.
Chemical control refers to the use of disinfectants, antiseptics, antibiotics, and chemotherapeutic antimicrobial chemicals
Over time, data that support the successful evolution of a species would include observations that describe

Help me past due Write down what you think will happen to the density of water if you add salt or sugar.
Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
A ______occurs when the Earth casts a shadow that partially or fully covers the Moon
O lunar eclipse
O summer solstice
O solar eclipse
Answer:
Lunar eclipse
Explanation:
During a lunar eclipse, the earth enters between the sun and the moon, thus preventing sunlight from reaching the moon. There are two types of lunar eclipses: A total lunar eclipse occurs when the moon and the sun are on opposite sides of the earth. When only part of the earth's shadow covers the moon, a partial lunar eclipse will occur. In some cases, it is called a blood moon, similar to the blood moon that occurs this month.

Amino acids with hydrophobic R groups are most often found in the interior of folded proteins. true false
Answer:
True.
Explanation:
Amino acids with nonpolar, hydrophobic R groups combine together inside the protein, thereby making hydrophilic amino acid that is outside to interact with the water molecules that surrond it. The hydrophobic molecules tend to avoid water by coalescing to form an oily or waxy droplet. This then make hydrophobic and amino acids to come together in the interior of proteins, which is far from the aqueous environment.
