AlexFokin [52]

Answer:

The TATA box helps  bind the <em>RNA polymerase</em> in the correct place.

Explanation:

The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.

The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.

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 <em>dichotomous</em> 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<u><em> into two groups</em></u>:

  • 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 <u>with a </u><u>tail</u> --------------------------- The only option is E

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

2  ---<em>Only for  group A, B, C, D, F, G---</em>

(a) <u>Legs</u><u> much longer </u>than abdomen and  cephalothorax ----------A and G

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

3  ---<em>Only for  group A, G---</em>

(a) <u>Hairs</u> on the legs -----------------------------------The only option is A

(b) <u>No hairs</u> on the legs ------------------------------ G

4  ---<em>Only for  group B, C, D, F---</em>

(a) Cephalothorax or <u>abdomen</u><u> segmented</u> ----------------The only option is D

(b) Cephalothorax or a<u>bdomen not segmented</u> ----------- B, C, F

5  ---<em>Only for  group  B, C, F---</em>

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

(b) Abdomen and cephalothorax <u>of different size</u> -------B, C

6  ---<em>Only for  group B, C---</em>

(a) Body <u>covered with long</u><u> hair</u><u> </u>----------------------------------The only option is C

(b) Body<u> </u><u>not covered with</u><u> hair</u> ------------------------------------B

A  →  <em>Tegenaria domestica</em>

B  →  <em>Ixodes hexagonus</em>

C  →  <em>Tyroglyphus longior</em>

D  →  <em>Chelifer tuberculatus</em>

E  →  <em>Abaliella dicranotarsalis</em>

F  →   <em>Poecilotheria regalis</em>

G  →  <em>Odielus spinosus</em>

Which of the following statements about eutrophication is TRUE?
Nostrana [21]

Answer:

C. It is driven by natural processes like rock weathering and nitrogen fixation.

Explanation:

It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.

This will allow the maximum growth of algae on the surface of the water.

It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.
