The right side of the heart receives: ____________
a) oxygenated blood from the pulmonary circuit.
b) deoxygenated blood from the pulmonary circuit.
c) deoxygenated blood from the systemic circuit.
d) oxygenated blood from the systemic circuit.

Answers

Answer:

b

Explanation:

The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.

The right side of the heart receives deoxygenated blood from the pulmonary circuit.

What is the function of the right side of heart?The pulmonary circulation carries the oxygen-poor blood from the right ventricle to the lungs, where it obtains a new blood supply. Returning the oxygenated blood to the left atrium follows. The right side of your heart draws blood from your veins that is deficient in oxygen and pushes it to your lungs where it is oxygenated and removed of carbon dioxide. Blood that has been oxygenated by your lungs is drawn from the left side of your heart and circulated through your arteries to the rest of your body.

Answers

Answer:

The KT boundary mark a mass extinction event the KT boundary is the time between the Cretaceous and Tertiary period.And asteroid hit the Earth at the end of the cretaceous and that caused the end of the cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there where many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth

What are somatic cells?

In humans, somatic cells are diploid, that means they include  units of chromosomes, one inherited from every determine. DNA mutations in somatic cells can have an effect on an individual, however they can not be surpassed directly to their offspring.

As new mutation occurs in a somatic cell of a reproducing organism, then percentage of the individual's offspring are likely to inherit the mutation is 0 % as they cannot be inherited.

What is Climate change?

This refers to the long-term shifts in temperatures and weather patterns. Global warming has resulted in the presence of warmer waters.

This promotes the development of stronger storms in the tropics, which can cause  loss of lives and properties.

Part A
Isobars are smooth lines that connect points of equal pressure on a map. They can be used to identify high- and low-pressure areas. In a high-pressure region, the air contracts and becomes warmer as it sinks. These regions are usually associated with dry weather caused by the evaporation of moisture. Low-pressure regions usually bring precipitation, because the air cools as it rises and the water vapor condenses. In the Northern Hemisphere, the wind blows clockwise around high-pressure areas and counterclockwise around low-pressure areas.

Question
This map shows the surface air pressure across the United States. The units are rounded to the nearest millibar. Follow the steps to complete the drawing.

Step 1: Isobars. Locate all points of 1024 millibar (mb) pressure in the northwest United States. Similar to a dot-to-dot coloring book, use a black pen to connect all four of the 1024 mb points. Your line should start and end at the point of 1024 mb pressure in Utah. Repeat this procedure with the next isobar value until all the points on the map have isobars running through them. Be sure that no set of isobars crosses another. Remember that not all isobars will be closed circles. Label each of your lines with the last two digits of the pressure reading (24, for example).

Step 2: Air Pressure. Locate the areas of the highest and lowest pressure on your map. Label these centers with a large blue letter H and a red letter L, respectively.

Step 3: Weather Conditions. Based on air pressure, locate the regions where you would expect to see rain or snow and shade them in green. Then shade the regions where you would expect to see clear skies in yellow.

Step 4: Wind Direction. Indicate the wind direction by drawing pink arrows around the letter H and around the letter L on your map.

Answers

Isolines are used to read create climatic maps. They provide information about barometric pressure, weather conditions, winds direction and speed.  

How to interprete a climatic map?

Meteorology is determined mainly by barometric pressure, which is the pressure exerted by atmospheric air on the earth's surface. It is measured in millibars.

Barometric pressure systems are closely associated with weather patterns, which is why it is used to create climatic maps.

Pressure,

An average pressure system ⇒ 1013 mb. A high-pressure system ⇒ 1030 mb.A low-pressure system ⇒ 1000 mb.

Isobars,

Used to read barometric pressures in climatic maps

These are curve lines that indicate the areas with the same barometric pressures.

They are arranged in concentric figures, one inside the other one. The smallest one indicates the pressure center.

                  -  High-pressure center is indicated with an H

                  -  Low-pressure center is indicated with an L

Isobars are significant when determining wind speed and direction.

Wind direction:

              - In High-pressure center is indicated with  

                 clockwise arrows in the northern hemisphere

              - In Low-pressure center is indicated with  

                 counterclockwise arrows in the northern hemisphere

Wind speed:

The closer isobars are between each other, the stronger and faster the wind is.

HIGH-PRESSURE SYSTEMS

Isobars: Isobars are more separated from each other.Mass of dense, cold, or cool and dry air. Since the air is dense it tends to descend.Air pressure: high - around 1030 mb-Weather conditions: clear, cloudlessWind direction: clockwise in the northern hemisphere, counterclockwise in the southern hemisphere

LOW-PRESSURE SYSTEMS

Isobars: close to each otherMass of light, warm and wet air. Since the air is light, it tends to ascend, creating clouds and rains.Air pressure: low -around 1000 mb-Weather conditions: cloudy, rainy, stormy. Wind direction: clockwise in the northern hemisphere, counterclockwise in the southern hemisphere

Go outdoors and look for ten different plants. See if you can figure out which type of seed dispersal each plant uses, and make notes about each one. Some may have more than one method of dispersal. If you find a plant that you suspect disperses seeds in a way that you haven't studied, try to figure out how the plant does it. When you're finished, write your discoveries in a list with the name of the plant you observed (if you know it; otherwise, describe the plant).

Answers

Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.

Some you wouldn't see by stepping outside, but it gives you a general understanding of what you should be looking for.

Name the four ways exoplanets are discovered? Which of those methods are dependent upon another star?

Answers

Answer:Any planet is an extremely faint light source compared to its parent star. For example, a star like the Sun is about a billion times as bright as the reflected light from any of the planets orbiting it. In addition to the intrinsic difficulty of detecting such a faint light source, the light from the parent star causes a glare that washes it out. For those reasons, very few of the exoplanets reported as of April 2014 have been observed directly, with even fewer being resolved from their host star
