Sometimes scientists make a mistake, or ___, and need to do the experiment again?

Answers

Answer 1
Answer:

Sometimes scientists make a mistake, or error, and need to do the experiment again.

The errors can occur at various stages, including experimental design, data collection, analysis, or interpretation.

  • When scientists make a mistake or encounter unexpected results, it can compromise the validity or reliability of their findings.
  • Mistakes can arise due to human error, such as miscalculations, misinterpretation of instructions, or accidental contamination.
  • Equipment malfunctions or technical issues can also contribute to errors in data collection or measurement.
  • In some cases, scientists may realize that they have made a mistake during the experiment, such as using the wrong reagent or applying an incorrect procedure.

Recognizing these mistakes and errors is an important part of the scientific process.

Thus, the complete sentence is "Sometimes scientists make a mistake, or error, and need to do the experiment again".

Which fact about fossils is MOST important to scientists who study evolution?

Answers

Knowing the age of the fossils is the most important factor for the scientists that study evolution.  

The age of the fossils is found out with the help of objective and radioactive dating. The fossils themselves generally cannot be dated directly, as the majority of them have no or less of the organic substance left in it, and dating with carbon 14 is only beneficial up to the age of 35000 to 50000 years.  

However, with the application of radiometric dating, the scientists are able to put an objective date. By determining the concentration of radioactive decay in specific elements since the solidification of the igneous rocks, one can find out the exact date of the fossil.  

The most generally used elements for radiometric dating of rocks are uranium, argon., potassium, and rubidium as they exhibit fairly long half lifes.  
A very important fact to be considered about fossils by scientists is the Age of the Fossil. This is found by Carbon Dating. The reason why the age is of high importance is because it determines during what time the fossil lived and how it is evolution.

Which fungal structure produces enzymes that break down food?

Answers

Hyphae fungi


When the spore lands and germinates in the orange, a small tubular extension starts to grow. This new cell will from a strand of hyphae, complete with a nucleus, organelles and cytoplasm. The tube is similar in structure to a straw, but instead of plastic, its firm cell wall or exterior is made of a strong substance called chitin.

The hyphae can now get to work on a piece of fruit, hyphae are crucial to the absorption of nutrients because they can contain a secret weapon: digestive enzymes. When the enzymes are released, they break down food so that its molecules can be easily absorbed. As the hyphae take in their nutrients, they add new cells and extend upward.

Is reproduction necessary for the survival of a species?

Answers

Yes. Forms of life cannot survive if they do not reproduce.
Absolutely! If a species does not reproduce, there is no replacement for the declining population and they soon die out.

Having warm weather all year with a distinct winter and summer season where winter is a long, dry, and slightly cooler season with only 4 inches of rain on average, and summer is a very hot, humid, and wet season with 15 to 25 inches of rain, with monsoon rains beginning in May describes the _______ biome(s).a.

Having warm weather all year with a distinct winter and summer season where winter is a long, dry and slightly cooler season with only 4 inches of rain on average and summer is a very hot, humid and wet season with 15 to 25 inches of rain, with monsoon rains beginning in May describes the savanna and grassland biomes. The correct option is option "b". 

Savanna and grassland is the correct answer. Those types of biomeds are characterized by the definition above, and two clear examples of these type of biomeds are India and certain part of Africa. Those types of biomeds create a unique life around them, when there is a lot of diversity and a lot of contrst between the season when it comes to life population, as often during the dry season some populations migrate towards more humid territories.
