Biology
1 answer:
AnnZ [28]3 years ago
7 0

Answer:

The lunar phases gradually change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around Earth and of Earth around the Sun shift. The Moon's rotation is tidally locked by Earth's gravity; therefore, most of the same lunar side always faces Earth.

What are Constant/control variables
Alik [6]

Answer:

constant = changes and control is used as the basis of comparison

Explanation:

Constant variables are variables that do not change

e.g such as the temperature ( if it's meant to be kept at a constant temp).

Control variables are meant to be kept constant to allow for a comparison and thus determine the effect of IV (independant variable) and DV ( dependant variable)

Cindy collects 20 insects for her biology class, all of which are spiders, dragonflies, and cicadas. (Note that a spider has 8 l
Ronch [10]

Cindy collects 4 cicadas in total.

Let,

D represent the number of dragonflies

C represent the number of cicadas

S represent the number of spiders

Since the total number of insects is 20:

Equation 1

D+C+S=20

A spider has 8 legs, a dragonfly has 6 legs, and a cicada has 6 legs. Since the total number of legs is 138:

Equation 2

6D+6C+8S=138

A spider has 0 wings, a dragonfly has 4 wings, and a cicada has 2 wings. Since the total number of wings is 36:

Equation 3

4D+2C+0S=36

Multiplying equation 1 with 6 and subtracting it from equation 2:

6D+6C+8S-6(D+C+S)=138-6(20)

2S=18

S=9

Multiplying equation 1 with 4 and subtracting it from equation 3:

4D+2C+0S-4(D+C+S)=36-4(20)

-2C-4S=-44

Substituting S with 9:

-2C-4(9)=-44

-2C=-8

C=4

Thus, Cindy collects 4 cicadas in total.
