The answer is <span>B. fibrin.
Through the process of elimination: thrombin and thromboplastin are enzymes so these choices are incorrect. Platelets are actually cells, which leaves us B. fibrin as the correct choice.
</span>A fibrinogen is a protein involved in the formation of blood clot. It is converted by enzyme thrombin into fibrin during blood clot formation.
Advantages:
>No cables needed.
>Multiple channels available.
>Wide bandwidth.
Disadvantages:
>Line-of-sight will be disrupted if any obstacle, such as new buildings, are in the way.
>Signal absorption by the atmosphere. Microwaves suffer from attenuation due to atmospheric conditions.
>Towers are expensive to build.
Answer:
oxygenation of the atmosphere
Explanation:
The "Great Oxidation Event" was one of the most important things happening on this planet. Without it, there could never be animals breathing oxygen, like insects, fish, and certainly humans. Moreover, this moment of our planet was one of the main responsible for the evolution of eukaryotes.
For decades, scientists have worked to understand how and why oxygen emerged. And they suspect that life itself was responsible for creating the air we breathe.
The latest findings suggest that life was undergoing a tremendous transformation before the "Great Oxidation." An evolutionary leap that helps explain what we know today.
Formed 4.5 billion years ago, the Earth, at the time of the Great Oxidation, was already inhabited. But only by unicellular organisms. It is not exactly clear when life began on the planet, but the oldest fossils of these microorganisms date back at least 3.5 billion years ago. This suggests that life had existed on earth almost 1 billion years before the "Great Oxidation." From the moment oxygen spread through the atmosphere, it was possible for these organisms to evolve into more complex life forms.
Answer: LABORATORY EXPERIMENTS
Explanation:
Exponential growth can be define as the increase in per capita growth of the population when the resources available are surplus. A limiting factor is the one which is capable of limiting the growth, abundance and distribution of population of species. Predator populations, habitat conditions and food resources all are examples of limiting factors which can limit the growth of population exponentially.
Laboratory experiments cannot be consider as limiting factor hence, are not responsible for limiting the exponential growth.
Decomposers are very important in our ecosystem, they are responsible for breaking down decaying bodies to transform into nutrients. Without decomposers, plants will not be able to get enough nutrients that it needs to grow
