Answer:
Without dark matter galaxies would loose an extreme amount of gas required to create stars.
Without dark matter the universe wont have as many galaxies clumped together forming larger versions of those galaxies. This would cause a change in the structure of the "skeleton" of the web.
(Hope this can help, I didn't do exactly as it is said to because that is your job)

Explanation:
Forbes gives somewhat of an explanation if you are curious.
(Ethan Siegal, "The Universe Would Be Very Different Without Dark Matter", Forbes)
Dark matter makes up most of matter in the universe and is found by a quarter of the total composition of the space. After the event of the big bang, the universe expanded and dark matter grew.
Dark matter accounts for about 85% of the matter in the universe. Its presence can be felt in the gravitational effects. Dark matter doesn't interact with the electromagnetic field. After the big bang event, the dark matter still can be found in larger galaxies and contest about 26% of mass-energy and 69% of dark energy. If there had been no dark matter there would be no structure of the cosmic web of galaxies. That is there would be no connection between the galaxies and would remain in isolated fragments.Thus dark matter is a link within and with the comic web.

D) the loudness we hear
What is the specific heat capacity for a 5 g sample of metal that absorbs
100 Joules of heat energy when its temperature changes from 10 degrees
C to 40 degrees C?*
A) 15, 000 J/gC
B) 2 J/go
C)0.67 J/gC
D) 0.50 J/go
Answer:
The specific heat capacity is 0.67 [tex]\frac{J}{g*C}[/tex]
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
The amount of heat that a body receives or transmits is determined by the following expression:
Q = c * m * ΔT
Where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
This expression indicates that between heat and temperature there is a direct proportional relationship.
In this case:
Q= 100 Jc= ?m= 5 gΔT= Tfinal - Tinitial= 40 °C - 10 °C= 30 °CReplacing:
100 J= c*5 g* 30°C
Solving:
[tex]c=\frac{100 J}{5 g* 30C}[/tex]
c= 0.67 [tex]\frac{J}{g*C}[/tex]
The specific heat capacity is 0.67 [tex]\frac{J}{g*C}[/tex]
