What is the effect of soil salinization on crops?

matrenka [14]

Answer:

Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Answer:

Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):

NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2

Explanation:

The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.

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>
