Answer:

Isobar lines mark wind speed and direction. Winds are directed from areas where there is more atmospheric pressure to where there is less. Therefore, we can know this information just by analyzing the values of isobars. When we see the isobars placed in smaller circles, the center indicates a center of pressure. It can be both high, with the symbol A, and low, with the symbol B.

We must know that the air does not flow down the pressure gradients. It moves around them due to the Coriolis effect (of the earth's rotation). Therefore, the isobars that are clockwise are anticyclonic flows and the opposite cyclonic flows. An anticyclone is synonymous with high temperatures and good weather. The cyclone is atmospheric instability that results in a storm. The closer the isobars are to each other, the stronger the wind speed will be.

When a cyclone takes place, it is usually accompanied by storms with an increase in clouds, winds, temperatures and rainfall. This is represented on the weather map with isobars close together. The arrows travel counterclockwise in the northern hemisphere and with a "T" in the middle isobar.

High pressure conditions do not represent rainfall. The air is drier and is represented by an H in the isobar of the medium. The arrows circulate in the direction of the wind. In the direction of clockwise in the northern hemisphere.

The first is the cold front. When a cold front passes through an area, rainfall is likely to be torrential and windy. In the meteorological maps they are represented by blue lines and triangles on the side of the direction of movement of the front.

The second type is the warm front. It implies an increase in temperatures as it approaches. The sky clears quickly when the front passes. If the mass of hot air is unstable, some storms may occur. They are represented on the weather map with red lines and semicircles on the side where they are directed.

The last type of is an occluded front. It is formed when a cold front exceeds a warm one. They are associated with some weather effects such as storms. There may be a hot or cold occlusion. When an occluded front comes, the air becomes drier. They are represented by a purple line and semicircles and triangles in the wind direction.

Assign each characteristic to the appropriate type of muscle fiber.

olga2289 [7]

I found the full exercise on the internet. Attached is an image of the characteristics and the types of muscle fibres.

Fast twitch:
- few mitochondria (most of the energy comes from acid lactic fermentation)
- low myoglobin content (O2 is not used as the main source of energy)
- shorter twitches
- anaerobic (uses mainly glucose and no O2)
- easily fatigued (as soon as glucose storage finishes fatigue comes in)
- high glycogen content (glucose as the main source of energy and therefore more glucose storage in the form of glycogen)

Slow twitch:
- high myoglobin content (energy comes from O2 and therefore is needed much myoglobin)
- aerobic (uses O2)
- low glycogen content (as O2 is the main source of energy, glucose is not needed as much)
-longer twitches

A scientist wanted to see if the number of eggs in a nest varied according to latitude. She decided to study a specific species

77julia77 [94]

Answer:

A. Does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?

B. The latitude of the area

C. The number of eggs

D. The species of the bird

E. The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.

F. 600 nests

G. The number of eggs

Explanation:

A. In the investigation, the scientist wanted to see if the number of eggs in a nest varied according to latitude, therefore, the question she will be seeking an answer to is: does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?

B. The independent variable is the variable that is not affected by the other variables being measured in an investigation. In the investigation by the scientist, the latitude of an area is the independent variable in that it is independent of changes in the other variable- the number o eggs- in the investigation.

c. The dependent variable is the variable that is affected by changes to the other variable in an investigation. The number of eggs is expected to vary according to latitude, is therefore, it is the dependent variable.

D. The constant is the factor that does not change during the experiment. The bird species is the constant as it does not change in the investigation.

E. A hypothesis is a specific statement predicting the result of an investigation or study.

In this study, the hypothesis could be: The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.

F. The sample size gives the the total number of subjects, individuals or observations in a study. In this case, the subjects are bird nests, and the sample size is 600 nests.

G. The number of eggs in all the nests were counted; therefore, it is the repeated measure.

The events of childbirth are associated with the process of positive feedback. describe these events.

sveticcg [70]

One example of a positive feedback loop in childbirth is contractions. When the contractions start, they produce oxytocin, which stimulates stronger contractions, which produce more oxytocin.
