According to the research, the respiratory and circulatory systems have the anatomical structures responsible for pumping and distributing blood throughout the body.
How the respiratory and circulatory systems work together?The circulatory system has the main function of transporting blood throughout the body; this blood will contain nutrients and oxygen so that they reach all the cells where the respiratory system is responsible for capturing oxygen.
In this sense, this process is carried out by means of two circuits that process blood with oxygen and deoxygenated blood:
Systemic circulationPulmonary circulationVeins that contain oxygenated blood, such as the pulmonary veins, carry oxygenated blood from the lungs to the heart.
Therefore, we can conclude that the respiratory and circulatory systems work through two circuits to transfer oxygen and nutrients from the blood to the cells.

You may hear the phrase: "We are losing our soil." Sounds serious…but how do we lose soil? Nick Comerford, a member of the Soil Science Society of America (SSSA) and professor at the University of Florida, provides the answer.
Soil erosion is the movement of soil by wind or water, and it's through erosion that soil is "lost." If it is an organic soil, we also lose it by subsidence which happens when an organic soil is drained and its organic matter decomposes.
We lose about 1.7 billion tons of soil per year from just our cropland. That is a lot, but it's better than it used to be. Over the past 25 years we have reduced soil erosion by over 40%, mainly by conservation practices such as conservation tillage, terracing, cover crops, and grass waterways. It can take roughly 500 to 1000 years to form one inch of soil, depending on the climate and the material from which soil forms.
With that in mind it is not hard to see that soil is a non-renewable resource and worth protecting. Since the soil is the source of water and nutrients for plants as well as a bioreactor to purify and filter water, it is crucial to our quality of life.
Soil erosion occurs when the soil is not protected from the elements. Remove the plants and mulch from mineral soil and things start to happen. Raindrops can break apart the soil making it easier to move it by wind and water. The water's ability to enter the soil is reduced and more water now can flow over the top of the soil. Unfortunately, water is powerful and can carry away soil particles if it flows overland. Since water flows downhill, that's where the soil goes once water erosion begins.
Where does the soil end up? It might end up at the bottom of a hill, or it might end up in a river or stream or in the ocean, or it might end up in a reservoir. If the soil ends up in a reservoir, it limits the space for water and has to be removed by a very expensive process called dredging. If the soil dries out while it is unprotected, then wind can pick it up and move it downwind.
Organic soils can be drained. When drained, they decompose and this is called subsidence. In the Everglades area of Florida where soils have been drained for agriculture, organic soils have lost as much as five feet or more of their organic matter. Organic soils are preserved by not draining them. Letting them stay saturated with water allows them to continue to build over time.
Soil erosion is expensive. It costs the United States about $44 billion per year. Preventing erosion means taking care of the soil. That means protecting it with mulch and plants, not plowing on steep slopes, and maximizing the amount of water that enters the soil while minimizing the water that runs over the soil.
In this text the author wants to inform about the importance of the soil for human life and explain what are the problems that affect this resource.
What is a summary?A summary is a term that refers to a type of written text that is characterized by synthesizing the main ideas of a text. Generally, the abstract is a way of exposing the same thing that is exposing a text with a smaller extension because the abstracts usually have about 25% of the extension of the original.
Summary of the textIn reality, the soil is lost, according to Nick Comerford professor at the University of Florida, soil erosion is one of the major problems that affects this resource. Nick refers to erosion as the phenomenon whereby the soil moves as a result of the action of water and wind.
On the other hand, Nick points out that in the United States about 1.7 billion tons of soil are lost each year. Additionally, during the last 25 years, conservation practices have allowed 40% more soil to be conserved.
According to the above, it can be inferred that the soil is a non-renewable resource and that its value for a good quality of life in general is very high because it is a resource that has to do with the production of water and nutrients for the floors.
On the other hand, we must know the factors that cause the soil to erode, some of these phenomena are: the lack of protection of the soil, the beating of raindrops and the movement of the wind. In most cases, soil particles that are carried by water end up deep in bodies of water.
Another action that deteriorates the quality of the soils is the drainage of soils, an example of this is found in the state of Florida where the soils have lost up to five of their organic matter as a result of drainage.
Finally, the loss of land generates great economic losses for the nation of about 44 billion a year. Therefore, the call is for us to protect the soil from erosion to prevent its deterioration.

after a signal binds to a signal receptor, the next step is transduction. why is the signal transduction step necessary?
After a signal binds to a signal receptor, the next step is transduction. The signal transduction steps are necessary because the more molecules that share the obligation of passing the sign to spark off the effector the greater fast and more efficaciously the message can spread.
Signal transduction is the method via which an extracellular molecule turns on a membrane protein, which in flip turns on molecules inside the mobile.
Signal transduction pathways are used to deliver messages of ligands into adjustments of the organic activity of target cells. Aberrant signaling through communication pathways may additionally result in illnesses, and signal transduction pathways are increasingly the target for drug development.
In effect, signal transduction is stated to have three steps: First, reception, wherein the sign molecule binds the receptor. Then, signal transduction, that's wherein the chemical signal affects a series of enzyme activations. in the end, the reaction, is the ensuing cell responses.

The statement it prevents particles from transferring thermal energy between the inner and outer bottles best describes the purpose of the vacuum inside a thermos (Option D).
What is the meaning of a vacuum?The main meaning of a vacuum is to leave space (empty space) in order to produce a completely closed system, which may be used for investigation purposes such as, for example, to understand how a steady temperature may affect a given enzymatic process.
In a vacuum, the energy can not be transferred and therefore the temperature will remain constant in the closed system. This situation allow us to understand certain physical and chemical processes in the real world.
Therefore, we can conclude that using a vacuum may be very useful to avoid the transference of energy and thus generate a completely closed system to study its properties and characteristics.

As discussed in this section, angiosperms often coevolve with animals. Sometimes, the corresponding adaptations enable certain species of a flowering plant to be pollinated exclusively by a certain species of animal. How might such exclusive relationships boost a plant's reproductive success?
Can you think of any disadvantages?
According to a generally recognised theory, insect pollination dominated angiosperm pollination throughout the Early Cretaceous, and by the Mid-Cretaceous, specialisation had increased.
Why are angiosperms so successful due to their adaptations?Two unique reproductive structures that angiosperms have evolved are flowers and fruits. Flowers is the flower's primary purpose. The ovule and growing embryo inside a receptacle are likewise shielded by flowers. The fruit's purpose is to disperse seeds.
Flowers draw animal pollinators with their vivid hues, potent fragrances, and delicious nectar. Flowers give pollinators nectar in return for their pollination. Grass species like domestic grasses are among of the angiosperms that have evolved most recently. They produce a lot of huge, nutritious seeds that may be eaten.

Like many enzymes, catalase has effects that are regulated by the temperature of the environment. The structure of catalase and the hydrogen bonds it is intended to break are both impacted by temperature. The hydrogen bonds between molecules of hydrogen peroxide relax as temperature rises toward the optimal point, facilitating catalase's reaction with the molecules. The enzyme denatures and its structure is upset if the temperature rises above the ideal level.
For example, The ideal temperature for catalase in human is 37 degrees Celsius.
