Answer:Amphibians evolved during the middle of the Devonian period (416 to 359 million years ago) from the lobe-finned fish of the vertebrate class Sarcopterygii. Species within the genus Ichthyostega (members of the Labyrinthodontia subclass) are considered by some scientists to be the earliest amphibians.

True [87]

The organism which is multicellular and that it first digests, then absorbs nutrients from the environment around it, best fits into the classification of fungi.

Multicellular organisms are those that are comprised of more than one cell in their body. They can either have a loose composition of various cells or have a complete organ-system kind of body. The example include all animals and plants.

Fungi is the kingdom consisting of multicellular eukaryotic organisms. The mode of nutrition in fungi is heterotrophic. It can be of various types like holozoic, saprophytic and parasitic. However the saprophytic mode is more predominant.

What was the purpose of the Declaration
Kay [80]

Answer:

Pretty sure its A.

Explanation:

I don't think it would be B. because they already wrote the Declaration of Independence, so why would they have him write a set of laws?

I don't think it would be C. because the Patriots were willing to go to war over this, hence the American Revolution.

This is by process of elimination so i'm not totally sure this was right. Hope it helps though!

Yolk molecules tend to accumulate in the vegetal half in the fertilized eggs of most animals, and the presence of yolk can slow
bazaltina [42]

cells in the vegetal half of the embryo should be unpigmented those in the animal half and there should be heavily pigmented.

Explanation:

The Yolk molecules moving in the vegetal halves of the egg which is the case in most of the animals, slows down the cell division. These lesser division area or the zone demarcates the area to be vegetal pole and due to lesser cell division, it becomes unpigmented or less pigmented Based on the observation time and perspect with assuming no movement.

The pole opposite to the vegetal, is animal pole which with absence or less of yolk, gets more ability to divide and hence become more pigmented or heavily pigmented. This brings polarity to the egg and becomes telolecithal egg.
