Answer: see below.
Explanation:
gases dissolve more in colder water, so in summer the water can become oxygen depleted. Evaporation in summer can reduce water volume; even in summer rainfall climate evaporation rates may exceed precipitation. Evaporation will also cause higher conentrations of solutes of which some may reach toxic levels. Summer sun may also cause algal or cyanobacterial blooms which can further deplete dissolved oxygen and may release toxins into the water.
Viruses do not have nuclei, organelles, or cytoplasm like cells do which is why they have no way to monitor or create change in their internal environment.
Answer: B and D
Explanation: just took the assignment
Answer:
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.
Explanation:
Option 1.
4y=12
Dividing 4 both sides
y=3
Division property should be used.
Option 2.
Cross multiplying each other,
y=12(4)
y=48
Option 3.
2(4y)=12
Opening bracktet in LHS
8y=12
Dividing both sides by 8 i.e.
Division property is used.
Option 4.
y+4=12
Subtracting both sides by 4 i.e.
Y+4-4=12-4
y=8
Subtraction property is used.
<em><u>It means that in option (4) Soo-Jung used the subtraction property of equality to solve an equation for y.</u></em>
