Sedbober [7]4 years ago

Answer:

e. way that the organism grows

Explanation:

During the evolution of animals, there was a great increase in body complexity, emerging specialized organ systems and differentiated structures, which also contributed to the classification of animals.

The protostomies differ mainly in that the blastopore (opening that forms at the stage of the gastrula during embryonic development) will give rise to the embryo's mouth, and the anus will open posteriorly (In deuterostomies, the anus opens first, and the mouth opens later).

Some <u>examples</u> of protostomies are worms, mollusks and arthropods.

eimsori [14]

Answer:

D. all of the above​

Explanation:

Biome refers to a large and relatively distinct terrestrial region having similar climatic conditions regardless of where it occurs on Earth. The characteristic climatic conditions (temperature and precipitation being the most important ones) and soil type of each biome type determine the type of plant species found there. Therefore, each biome is characterized by specific flora.  

For example, a desert biome is a temperate or tropical biome characterized by a lack of precipitation, seasonal variations in temperature and poor soil type with low organic matter that limits plant growth. Desert biomes have only the plant species that can survive these harsh conditions.

Lelu [443]

Answer:

For number 3:

The bacterial cell is a prokaryotic cell and the fungal cell is a eukaryotic cell.

Explanation:

I cannot see the cells to answer number 4, but for number three, bacteria is a prokaryote and fungal cells are eukaryotes. You can most likely determine this by the presence of a nucleus (a prokaryote cell will not have one where a eukaryotic cell will).
