Answer:

Birds evolved from a group of meat-eating dinosaurs called theropods. That's the same group that Tyrannosaurus rex belonged to, although birds evolved from small theropods, not huge ones like T. rex.

P,T,Y refers to the set of points which are collinear and is therefore denoted as option C.

<h3>What are Collinear points?</h3>

This is commonly used in geometry and refers to the set of points which lie on the same straight line and are always close to each other when compared to other points. It is possible for them to appear on different planes only and the value by the triangle from the three points is usually zero.

In the example give, only P,T and Y are the points which lie on the same line while other options have points which lie on different lines thereby making them incorrect.

This is therefore the reason why option C was chosen as the most appropriate choice.

Identify each of the following half-reactions as either an oxidation half-reaction or a reduction half-reaction. half-reaction i
Natasha2012 [34]

Answer: Oxidation reaction:  Al(s)\rightarrow Al^{3+}(aq)+3e^-

Reduction reaction:  Sn^{2+}(aq)+2e^-\rightarrow Sn(s)

Overall redox reaction : 2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Al(s)\rightarrow Al^{3+}(aq)+3e^-

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Sn^{2+}(aq)+2e^-\rightarrow Sn(s)

Overall redox reaction : 2Al(s)+3Sn^{2+}(aq)\rightarrow 2Al^{3+}(aq)+3Sn(s)

Explain what golden poison frogs, kokoe poison frogs, and black-legged poison frogs have in common
telo118 [61]
The family of poison dart frogs (Dendrobatidae) boasts over 245 species, displaying an astonishing array of colors and potency. The brilliant colors and patterns range from strawberry red, canary yellow, and sunny orange to metallic green and black with yellow polka-dots. When eaten, some merely taste bitter or irritate the predator’s mouth with burning or numbness; a few, however, are truly deadly, even to humans. the Golden poison frog is <span>the deadliest animal on land(poison wise) but the Black-legged poison frog is right up there next to it. both can easily kill a human. Though no deaths have been confirmed, the Kokoe poison frog can theoretically also kill a human, it is just as toxic as the black-legged poison frog. so what do they all have in common? they can all kill humans

i hope this helps, please give me brainliest </span>
