Answer:

-heat

Explanation:

Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things. When the heat waves hits the cooler thing, they make the molecules of the cooler object speed up.

Good luck!!

Answer:

Explanation:

Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .

Which is a shorter process - (circle one) selective breeding or natural selection?

andrey2020 [161]

Answer:

Selective breeding.

Explanation:

Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

If a molecule of co2 released into the blood in your left toe is exhaled from your nose, it must passed all the following except

Feliz [49]

Answer:

The correct answer is option a, that is, pulmonary vein.

Explanation:

After getting discharged from the left toe, the molecule of carbon dioxide is exhaled through the nose, and in the process, it moves via the trachea, the alveoli, the right ventricle, and the right atrium. However, it does not passes through the pulmonary vein as the prime function of the pulmonary vein is to carry oxygenated blood obtained from the lungs and to pass it to the heart's left atrium.

The pulmonary vein is different from other veins found within the body, which carries deoxygenated blood or blood filled with carbon dioxide from different parts of the body to the heart. Thus, it is clear that carbon dioxide does not pass through the pulmonary vein.

The plates of the lithosphere move (or float) on this hot, malleable __________ _________ zone in the upper mantle, directly und

zysi [14]

Answer:

the plates of the lithosphere move (or float) on this hot, malleable semi liquid zone in the upper mantle, directly underneath the lithosphere

Explanation:

Lithosphere is the outermost layer of earth surface which contains crust and uppermost solid mantle.
Tectonic plates are subdivision of lithosphere where tectonic activities take place. Tectonic activities often occur in Lithosphere which affects the structure of this layer by changing the landscape on earth surface.
The Lithosphere is the layer where soil forming process takes place. The lithosphere influences temperature difference on earth when it reacts with the other layers called atmosphere, hydrosphere and cryosphere.

In humans, Rh+ blood is dominant to Rh–. A man and woman are both Rh+, but their first child is Rh–.

shusha [124]

Answer:

a) There is a 25% chance that their next child will be Rh-.

b) There is a 3/8 chance for a Rh+ girl

Explanation:

As we know from the question that Rh is a dominant gene. A person having only one allele for the gene will show its effect as it is the dominant character.

This means that for a person to lack the Rh factor, it shall not have any allele with the Rh factor.

To illustrate the result, lets draw a punnet square:

Rh+ Rh-

Rh+ Rh+/Rh+ Rh+/Rh-

Rh- Rh+/Rh- Rh-/Rh-

For the probability for it to be a girl, we know that there are 50-50 chances for the next baby to be a boy or a girl. The chance of being Rh+ are 75% for the next baby.

Hence,

3/4 multiplied by 1/2 is 3/8 ,which is the chance for the next baby to be a girl with Rh+ factor.
