Cindy collects 20 insects for her biology class, all of which are spiders, dragonflies, and cicadas. (Note that a spider has 8 legs and no wings, a dragonfly has 6 legs and 4 wings, and a cicada has 6 legs and 2 wings.) She counts 138 legs and 36 wings altogether. How many cicadas does Cindy collect in total
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

Luke is a quarterback on a football team. He throws the ball into the air and the wide receiver catches it and scores a touchdown. In a neuron, which physical part plays a role similar to that of the wide receiver in football
A dendrite is a neuron whose physical part plays a role similar to that of the wide receiver in football
The finger-like cells called dendrites are found on the terminal of a neuron. They are tiny, branching fibers that protrude from the nerve cell's cell body. This fiber expands the area that can be used to receive incoming data. The receiving or input parts of a neuron are called dendrites.
Appendages called dendrites are made to receive signals from neighboring cells. They take the form of projections with a tree-like structure that are triggered by other neurons and carry the electrochemical charge to the cell body (or, more rarely, directly to the axons). These little protrusions relay electrical stimulation to the soma and take in information from neighboring neurons. Synapses also cover the dendrites.

Suppose a mouse develops loss of sodium pump activity in the thick ascending limb of the loop of henle in all of the nephrons in both kidneys. What problem would you expect this mouse to have?.
A tendency to drink more water than normal accompanied by excretion of dilute urine.
What happens in the thick ascending limb of loop of Henle?Sodium chloride (NaCl) is actively reabsorbed by the thick ascending limb of loop of Henle, but water cannot pass through it. A lumen-to-interstitium osmotic gradient and medullary interstitial hypertonicity are consequently produced as a result of this segment's increase in the interstitial fluid's osmolality.
If the sodium pump loses its activity then sodium is not reabsorbed in the thick ascending limb of loop of Henle. The concentration of sodium chloride increases in the interstitial fluid and hence more water will be needed to counter the effect and more dilute urine will be excreted out.

The pressures in the atria and ventricles that would cause the AV valves to open. This is when the pressure in the atria would be greater than the pressure in the ventricles.
What does pressure in the atria cause?The pressure drops below 120 mmHg as the ventricles relax, causing the semilunar valves to close. As the pressure continues to fall, the atrial pressure exceeds that of the ventricles, and the atrioventricular valves open. Meanwhile the blood is being pumped around the body.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.
Based on this information, determine the type of boundaries these two new plates would share with each other and the Arabian Plate.
In divergent boundaries, plates separate from each other and new crust is created between them. The boundary these two new plates would share with each other and the Arabian Plate is the divergent boundary.
What are the three types of boundaries?I. Divergent
A new crust is created by the rising molten materials coming from the mantle.
Two plates separate, and a stream of hot material creates a new seabed between them. It occurs in an expansion of the sea bottom.
As old plates get separated, new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
II. Convergent.
When two plates move forward to each other, they end up colliding and causing the deformation of one or both plates.
Three possible collisions might occur,
• Two oceanic plates might collide ⇒ subduction
• Two continental plates might collide ⇒ obduction
• Oceanic plate and continental plates collide ⇒ Subduction
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur on the continental plate.
In the exposed example, the African plate is splitting up into two parts, meaning these two parts are separating from each other. A new seabed is created between the Nubian Plate and Somalian Plate.
Since these plates are also separating from the Arabian Plate, we can also assume a new seabed is emerging between them.
