Use the key to identify each species. Write the letter of each species (A to G) in the correct

sveticcg [70]

Dichotomous keys are useful to identify organisms according to their morphological traits. The given key provides enough macroscopic morphological traits to identify these Arachnida species.

-----------------------------------------------

A dichotomous key is a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.

The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

In the exposed example, as the key provides morphological traits, we will separate the organisms into two groups:

the group that has the trait
the group that does not have it.

By recognizing each trait in each of the individuals, we will get to identify the species.

1

(a) Abdomen with a tail --------------------------- The only option is E

(b) Abdomen without a tail ---------------------- All the others A, B, C, D, F, G

2 ---Only for group A, B, C, D, F, G---

(a) Legs much longer than abdomen and cephalothorax ----------A and G

(b) Legs not much longer than abdomen and cephalothorax----- B, C, D, F

3 ---Only for group A, G---

(a) Hairs on the legs -----------------------------------The only option is A

(b) No hairs on the legs ------------------------------ G

4 ---Only for group B, C, D, F---

(a) Cephalothorax or abdomen segmented ----------------The only option is D

(b) Cephalothorax or abdomen not segmented ----------- B, C, F

5 ---Only for group B, C, F---

(a) Abdomen and cephalothorax of the same size --------The only option is F

(b) Abdomen and cephalothorax of different size -------B, C

6 ---Only for group B, C---

(a) Body covered with long hair ----------------------------------The only option is C

(b) Body not covered with hair ------------------------------------B

A → Tegenaria domestica

B → Ixodes hexagonus

C → Tyroglyphus longior

D → Chelifer tuberculatus

E → Abaliella dicranotarsalis

F → Poecilotheria regalis

G → Odielus spinosus

One a feature of the structure of all DNA Molecules is the

liberstina [14]

Answer:

The structure of the DNA is ideal for the complex function that it plays.

Some of the features of the structure of all DNA molecules are:

Sugar- phosphate backbone:

The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.

Hydrogen bonds:

The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.

Coiling:

The structure of the DNA is coiled and super coiled so that it can fit into an organism.
