Your question should have a picture in other to answer the question:)
For real lo people just be putting anything
First question:
a. Gastrulation
Gastrulation is a phase<span> of the </span>embryonic development<span> in </span>animals. It doesn't occur in plants or any other organism. The other options can be put apart because <span>multicellularity, sexual reproduction, and </span>flagellated sperm are also characteristics that are present in plants, for example. Heterotrophic nutrition is something that's part of all <span>animals as well as non green plants.
Second question:
a. M</span><span>ulticellularity
</span>Synapomorphy is <span>a shared </span>trait <span>that distinguishes a </span>clade<span> from other organisms. C</span>hoanoflagellates are considered the most close ancestors to the animals distinguishing from them by multicellularity. They are very studied with the purpose to know the mechanisms of colonies' formation and evolution to multicellular animals.
Third question:
<span>d. Choanoflagellates
This are the most closely related living protist group. The </span>choanoflagellates are very similar to the ch<span>oanocytes of the sponges bringing them into closeness with the animals. They even aggregate in colonies, and are thought, because of all of this, to be the closest branch of single cells to that of the animals.</span>
The best way to get the right amount of vitamins needed from proper growth and development is to eat a variety of foods that high in vitamins every day. If a person isn't able to eat the foods daily, they can take a multi-vitamin. But the best answer will be B.
The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.
Option C
<h3><u>
Explanation:</u><u> </u></h3>
Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.
Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.
