<u><em>ACCORDING TO THE NORTH CAROLINA CLIMATE OFFICE:</em></u>

<u><em></em></u>

A warm front is the surface boundary between a warm air mass and a cold air mass it is overtaking. The warm air moves into an area of colder, drier air. The air masses do not readily mix; therefore the warm air rises slowly over the colder air because it is less dense. This produces clouds and precipitation well ahead of the approaching warm front, since warm air  in the southeastern US usually has higher water vapor content than cool air. Steady precipitation usually persists along the boundary of a warm front. This amount of precipitation, however, depends on the amount of moisture in the air ahead of the surface front. If the warm air is relatively dry and stable, precipitation would not be likely to occur. If the air is moist and conditionally unstable, heavy precipitation could occur over a broad area.

Occluded fronts form when a cold front catches up to a warm front because cold fronts move along much faster than warm fronts do. The cold front over takes the warm front and cold air moves into cooler air ahead of the warm front. Occluded fronts are represented on weather maps as alternating warm and cold front symbols in purple pointing in the direction the front is moving. Occluded fronts are not particularly common in the southeast US. The low pressure centers may begin in the south, but will typically move to the northeast and form an occlusion farther north. The precipitation patterns for an occluded front typically follow the same patterns as a cold front. Temperature will vary after the occluded front passes depending on the different air masses that are interacting with the occlusion.

It would cause Rain. But a cold front. Fronts are always in relation to moving cold air A cold front is the advancing edge of a cold air mass and a warm front is the retreating edge of a cold mass. If the cold air mass is displacing the warm air front then the cold air is advancing.

What type of selection relates to the average birth weight of humans babies?
vovangra [49]
<span>Human weight at the time of birth is influenced by stabilizing selection. Stabilizing selection, also known as negative selection, purifying selection or normalizing selection, is a type of natural selection in which genetic diversity decays according to a particular value of the character. This is the most common mechanism of action of natural selection.</span>

How does oxygen move from the respiratory system to the circulatory
slamgirl [31]

Answer:

D. By diffusion across a capillary wall

Explanation:

D is the best answer because gas exchange takes place in our lungs. Our lungs have alveoli which have a network of tiny blood vessels called capillaries, here the O2 diffuses the capillary wall to enter the bloodstream, and similarly CO2 diffuses out and we exhale it our from our lungs.

1) A plant gets 628.3 kcal of energy from the sun, what energy is left at the quartenary consumer level?
Jobisdone [24]

1. The energy left in the Quaternary consumer level is 0.06283 kcal.

2. 0.65 units of energy  is still available at the tertiary consumer level.

<u>Explanation:</u>

Energy flow in an ecosystem obeys the ten percentage law According to which ten percentage of energy from a trophic level gets transferred to the next trophic level. In the given question plants belong to the trophic level , producers  and it transfers 10 percentage of its energy to the primary consumer level.

In the question 1 the energy that the producers have is 628.3 kcal. Ten percentage of this i.e 62.83 kcal gets transferred to the primary consumer level. Ten percent of that which is 6.283 kcal gets transferred to the secondary consumer level.  Ten percent of 6.283 kcal i.e  0.6283 kcal energy is transferred to the tertiary consumer level.

Thus the Quaternary consumer level gets ten percentage of 0.6283 kcal i.e 0.06283 kcal. In question B the initial energy at the primary level is 650 units. Ten percentage of 650 i.e 65 units reach the primary consumer  level. Ten percentage of this 65 units then reaches the secondary consumer level. Thus the secondary consumer level has ten percent of 65 i.e 6.5 units of energy.  

So the energy that reaches the tertiary consumer level is ten percentage of 6.5 i.e 0.65 units.
