Can our cells carry out cellular respiration without oxygen? If so, how?

Justin has type A blood and his wife Brittany has type B blood. Justin's parents both have type AB blood, and Brittany's parents

Ad libitum [116K]

Answer:

Option D

Explanation:

Given

Justin has type A blood . Both the parents of Justin has AB blood type

Brittany has type B blood and both the parents of Brittany has AB blood type

This make it clear that -

Genotype of Justin is AA

Genotype of Brittany is BB

Now if Justin is crossed with Brittany , following blood groups in offspring is possible -

AA * BB

AB, AB, AB, AB

Thus, none of the offspring will have A blood group. Thus the chances that Justin and Brittany's son has type A blood is $0$ %

Option D is correct

Numbers are expressed in scientific notation using exponents

Nimfa-mama [501]

By using exponents, we can reformat numbers. This can be helpful, in much the same way that it's helpful (that is, it's easier) to write "twelve trillion" rather than 12,000,000,000,000., or "thirty nanometers" rather than "0.00000003 meters

Which is the least number of seismograph stations needed to locate the epicenter of a earthquake

Hunter-Best [27]

At least three seismograph stations are needed to locate the epicenter of a earthquake.

Further Explanation:

An earthquake occurs when two region of the earth slip past each other. Fault plane is the area where the slip occurs. Hypocenter is the region below the earth’s surface where earthquake starts while the epicenter is the region above it.

The earth consists of four major layer:

1. Inner core

2. Outer core

3. Mantle

4. Crust

Seismographs is an instrument used to record the earthquake. The recording done by this instrument is called as the seismograms.

The seismograph comprises of:

1. A base: is fixed tightly in the ground

2. Heavy weight: hangs freely

When the earthquake occurs, the ground shakes and in turn the seismograph also shakes while the hanging weight does not shakes. During the earthquake, the difference in the location between the shaking piece and the motionless piece is recorded. Magnitude of the earthquake is recorded as one for each earthquake. The magnitude of earthquake is measured by the Richter scale but is more commonly measured through moment magnitude scale.

How do you calculate the velocity of the boat relative to the shore

Dvinal [7]

Answer:

Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.

This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.

Let's illustrate this with two examples:

1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.

So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.

2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s

So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
