Answer:

8.467 grams of oxygen

Explanation:

The law governing this problem is "The Law of Constant Composition "

As per this law, all compounds irrespective of their origin and source have the same composition and properties  in their purest form

It is a simple proportion and ratio related problem.

1.50 grams of carbon require 2.0 grams of oxygen

1.0 grams of carbon will require oxygen

= \frac{2}{1.5}

6.35 grams of carbon will require oxygen

\frac{2}{1.5}*6.35\\= 8.4666\\= 8.467

 It contain oxygen atom calculated below
<span>6.35gC x 2.00gO/1.50gC
 = 8.47g O 
</span><span>  The law is that a sample of a pure substance is the same as any other sample of the pure substance no matter what the source is

How do Venus flytrap obtain <br> homeostasis
Minchanka [31]
- The Venus Flytrap survives in subtropical wetlands, it is the environment the venus flytrap needs, for example on the east coast of the USA, Brazil and Argentina. This means the venus flytrap wants lots of sunlight and humid conditions.
- It also lives in places where there is a low mineral level in the soil, so it gathers these vital nutrients from catching and digesting insects.
- For reproductive purposes, the flowers of Venus flytraps usually grows on tall stalks far above the leaves. This adaption of the plant is made so the the insects pollinating the flowers do not get trapped in the leaves. This is an anatomical adaptation that affects the flowers and the stems.

Where should the origin of the swim bladder be placed on the phylogenetic tree?
dolphi86 [110]

Answer:

At the base of Actinopterygii

*This is a unique characteristic of this group.

Explanation:

A peculiar characteristic organ observed in ray-finned fish (as well as in Sarcopterygii, or lobe-finned fish) but not in cartilaginous fish like shark is the swim bladder.

This organ is often described to be a sac containing gas. It helps these set of fish adjust its buoyancy and its position in the water by regulating the concentration of gas present in it.

The swim bladder is formed as a pouch coming off the embryonic digestive tract, and in chondrosteans and holosteans, with a set of teleosts e.g. the eels, it maintains an open pathway to the esophagus. In majority of the bony fish, the swim bladder is totally sealed off, as gas levels in their swim bladder are regulated by producing gas into the bladder via a network of capillaries, the rete mirabile (Latin word for "marvelous net").

The swim bladder is homologous to the lungs of tetrapods. Since they are formed in the same vein. Few fishes that have an open swim bladder employs it as a breathing organ.
