How were aristotle's and linnaeus classification systems different?

1 answer:

8 0

Both Aristotle and Linnaeus classified animals and plants, considering where the species lived. However, Linnaeus delved further into classifying organisms looking at their morphology, with an ordered subset of the organism's class divided into five kingdoms: class, order, species, genus, and variety. The process of this classification is called Taxonomy, however, modern scholars also consider the evolutionary history of a species, in the classification process.

damaskus [11]

Answer:

lignified vascular tissue

Explanation:

Stems of Vascular plants are made of vascular tissues and lignin which gives it is characteristics stiffness and the ability to grow tall to access more light and air.

Help me on this please!! Question 4

Katena32 [7]

No problem
so
Chain 1. Sun -> Tomato plant -> Tomato -> You
The sun provides energy to the tomato plant which is used to grow a tomato which is eaten by you.
Chain 2. Sun -> Wheat -> Flour -> Bun -> You
The wheat uses the sun's energy to grow when the wheat is mature it is used to produce flour which is used to bake the buns for the hamburger which is then eaten by you again.
Chain 3. Sun -> Lettuce -> You
The lettuce grows and uses the sun's energy to live it is then eaten by you in the hamburger.
Hope this helps :).

Which of the following is an example of a weather event?

solong [7]

The correct answer is C. A windstorm blew down trees in the Boundary Waters Canoe Area in Minnesota on July 4, 1999.

Explanation:

A weather event refers to a specific phenomenon in weather that in most cases is not common but particular and specific, which is different to weather patterns, this includes specific hurricanes, abnormal rain patterns, etc. Considering this, the one that is an example of a weather event is "A windstorm blew down trees in the Boundary Waters Canoe Area in Minnesota on July 4, 1999" because this is a specific phenomenon rather than a pattern in weather as int the case of hurricane seasons or permanent weather conditions.

Comparing amino acid sequences in proteins has been used to determine the relatedness of organisms. Below is a graphic that show

Tju [1.3M]

Answer:

A) Species A and E are more closely related than either species are related to species D.

B) Between A and B = 99.1%

Between species A and C =97.5%

Between species B and C = 97.3%

Similarity in amino acids sequence reflects similarity in DNA sequence

C) Species A and E are most closely related

D) Species A and E have the most similarity in amino acid sequence, and hence DNA sequence.

Explanation:

A) The amino acid sequences of the protein, keratin, in species A and D has a difference of about 19 whereas species A and E have a difference of only 1. Therefore, it means that keratin in species A and D will have differences in structure whereas between species A and E, they would have almost the same structure.

Also, species D and E have a difference of 20 in their amino acids sequence, therefore, the structure of keratin in both species will have differences in structure.

B) Similarity between A and B:

450 - 4 = 446

In percentage: 446/450 × 100% = 99.1%

Similarity between A and C:

450 - 11 = 439

In percentage: 439/450 × 100% = 97.5%

Similarity between B and C:

450 -12 = 438

In percentage: 438/450 × 100% = 97.3%

The sequence of DNA of species determines their amino acid sequences because information in DNA is transcribed to RNA which are then used to make proteins. Therefore, if a species are very closely related, they are expected to have very similar genetic sequences and thus proteins too. This is reflected in similarity between amino acid sequences in their proteins.

C). Species A and E are most closely related.

D) Species A and E have only a single difference in their amino acids sequence for Keratin. This translates to about 99.7% similarity which is the highest among all the species compared. Therefore, species A and E are most closely related.
