A grassy meadow high in the Sierra Nevada Mountains of eastern California is known to support a variety of organisms. During the

summers when grass is thick and lush, and wildflowers abound, butterflies take advantage of this abundant nectar source. Bears graze on the berries in shrubs at the edge of the meadow. Deer also forage at the edge of the meadow. In the early mornings, coyotes are known to prey on the squirrel and mouse populations that burrow into the meadow soil. A variety of birds prey on the butterflies and other flying insects, such as bees and wasps.​The coyotes would be classified as ____.
1) producers2) primary consumers3) secondary consumers4) decomposers5) tertiary consumers

Answer:

Option C, Secondary consumers

Explanation:

Secondary consumers are the organism that feed upon the primary organism.

Now if we make a hypothetical ecosystem  for meadow area described in the question -

Plants/grass ---> squirrel/mouse-----> coyotes-------> bears ------> microorganisms

Here,  all chlorophyll containing organism that are able to produce food on their own are considered as producers thus, plants/grass will be the producers.

Mouse and squirrels directly feed upon the producers, therefore they shall be considered as primary consumers. Coyotes will be secondary consumer. Bears in the meadows are common predators of coyotes , therefore they will be the tertiary consumers and lastly  decomposes will come.

Hence, option C is correct

Answer:

2. Secondary consumers

Explanation:

Secondary consumers are consumers that can eat primary consumers for energy.

Primary consumers are always plant eaters.

Once DNA was shown to be the primary genetic material of life, a race among scientists took place to work out its structure. Whi
Naily [24]

Answer:

The discovery of deoxyribonucleic acid (DNA) forever changed the understanding of genetics, the study of how physical and physiological inheritance is passed down from generation to generation.

The DNA molecule was first identified in the second half of the 19th century. A century later, in the middle of the 20th century, the golden age of discoveries in genetics began, when the structure and functioning of the genetic code was defined.

Today, scientists are focused on researching how to edit DNA to correct mistakes and cure diseases of genetic origin.

DNA was first isolated in 1869 by the Swiss biologist Johan Friedrich Miescher. While studying the chemical composition of white blood cells, he observed that within the cells there was an isolated substance rich in phosphates, without sulfur and resistant to proteases, something that did not correspond to the typical structure of lipids or proteins.

Miescher baptized that new molecule as nuclein, since it was found in the nucleus of all the cells studied.

Between 1885 and 1901, the chemical composition of DNA began to be defined. In 1889 Richard Altmann, a German pathologist who had been a disciple of Miescher, redefined this substance with the term "nucleic acid".

For his part, the German doctor Albert Kossel discovered the existence of carbohydrates and some compounds or nitrogenous bases which he called "adenine", "guanine", "cytosine" and "thymine" within the DNA molecule. This discovery earned him the Nobel Prize for Medicine in 1910. The 20th century began with great advances in DNA research. During the 1920s, Russian-American biochemist Phoebus Levene determined the existence of RNA, another nucleic acid necessary for the transmission of genetic information.

Levene also detected the presence of phosphate group and a type of sugar called ribose, two essential components in the formation of DNA. Later, the biochemist discovered that the phosphate group, sugar, and nitrogenous bases bound together to form nucleotides.

Once the shape and composition of DNA has been discovered, the latest studies focus on how it works: seeing what chemical reactions take place inside the cell in order to try to reproduce them in the laboratory.

Explanation:

In this way, genetic editing techniques aim to modify the genetic code of some cells whose DNA is incorrect or damaged, which can cause disorders and diseases.

Evgen [1.6K]

Answer;

They have revealed new information about cell structure and processes.

Explanation;

-The Cell Theory states that, All living things are made up of cells, Cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.

-Most microscopes use lenses to magnify the image of an object by focusing light or electrons.

-The Invention of the Microscope helped the development of the cell theory because it allowed the scientists to actually discover that everything was made up of cells, and what cells do to come up with that theory. If the scientists did not see that cells existed, they could not have observed the cells easily and they would not be able to construct the cell theory.
