Which is biotic? wind iron gate sunlight dead leaf

Biology
2 answers:
Masja [62]3 years ago
4 0

Answer:

The answer is "dead leaf."

Explanation:

Although dead leaves are no longer alive, they were considered as once part of a living entity. Therefore, dead leaves are biotic factors. Wind, iron gates, and sunlight are not biotic components because they are the non-living parts of the environment that influence biotic factors. Hope this helps.

Biotic factors include plants, animals, fungi, algae, and bacteria.

its not wind that would be Abiotic

and its not sunlight thats also abiotic

an iron thing is not a living thing either so thats not the awnser so Its D. dead leaf because even though its dead its the closest thing to a biotic

julia-pushkina [17]

Answer:

Explanation:

Bones are organs composed of hard living tissue providing structural support to the body – it's scaffolding. It is a hard matrix of calcium salts deposited around protein fibers. Minerals make bone rigid and proteins (collagen) provide strength and elasticity. ... The outer layer of bone is called Cortical bone.

Is blood clotting an example of a positive or negative feedback mechanism? Explain your answer based on the description of the m
serg [7]

Answer:

Blood clothing is an example of positive feedback.

This type of feedback mechanism is useful to the body because it multiplies the factor that intervenes in clotting accelerating the process.

If a toxin affects the molecules that signal for platelets the feedback will not be effective enough to produce clotting and the body will keep bleeding.

Explanation:

Blood clotting is an example of positive feedback due to the fact that when the vascular endothelium is damaged  platelets will go to this area and activate themselves once they are in contact with the collagen fibers of the damaged structure. When the platelets are activated they will release the contents that is stored in their granules. One of the contents is a Gq-linked protein receptor cascade,  that will increase the concentration of calcium in the platelets. Calcium activates protein kinase C, which, in turn, activates phospholipase A2 (PLA2). PLA2  will modifies  an  integrin membrane  increasing its affinity to bind fibrinogen. The activated platelets change their  shape , and the fibrinogen cross-links with the integrin membrane aiding  in  the aggregation of adjacent platelets. After this the coagulation cascade takes place. there are two pathways the extrinsic  and the extrinsic one.

The extrinsic pathway will be activated due to tissular factor released  by the platelets and the intrinsic pathway will be activated due to endothelial collagen. The final product of both pathways is factor x.

Factor x will transform prothrombin into thrombin will activate the conversion of fibrinogen into fibrin. Thrombin will form a net of fibrin that will the clot.

A cascade reaction is useful because every component of the cascade are related making a quick reaction once that one of then is activated and can activate other or more factors.

If a toxin affects the molecules that signals for platelets, platelets will not go to the damaged area and in consequence there will not be thrombin and fibrin to form the clot together with platelets.
