The answer is single opening. The gastrovascular cavity varies from the alimentary canal in that only the gastrovascular cavity has only a single opening. In addition, an alimentary canal has two openings and food moves over it unidirectional. The gastrovascular cavity is a construction establish in primitive animal phyla. It is accountable in cooperation with the digestion of food and the transportation of nutrients all over the body.

Which describes a disruption in the water cycle that could affect photosynthesis?
belka [17]

The right answer is Transpiration.

In plants, plant transpiration is the continuous process caused by the evaporation of water from the leaves (and the corresponding recovery from the roots in the soil).


For large plants and helophytes, it can be very important. On average, a plant loses the equivalent of its weight in water per day. This explains the role played by large plant formations, including forests on the water cycle and climate.

When considering the evolutionary tree of life and the three domains of life, which statement best describes what likely happene
Fudgin [204]

Answer:

The answer is - Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Explanation:

The options are:

A. Bacterial and eukaryotic cells are more closely related to  each other than to archaeans, as evidenced by the fact that  bacteria and eukaryotes do not inhabit the most extreme  environments.

B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

C. Bacteria and archaeans are more closely related to each other  than to eukaryotes, as evidenced by their cell structures. Bacteria  and archaeans are prokaryotic, while all eukaryotic cells contain  mitochondria and other membrane-bound organelles.

D. The three domains of life are equally divergent from one  another, so no two domains are more closely related to each other.  This is supported by the evolutionary tree of life because three  branches extend from one node millions of years ago.

The answer is - B. Although their cell structures are very different, archaean and  eukaryotic cells are more closely related to each other than to  bacteria, as evidenced by the fact that Bacteria was the first  domain to split from the shared ancestor of Archaea and  Eukarya.

Archaea and bacteria are similar in terms of cellular organisation and size but are however similar to eukaryotes (eukarya) at the molecular level. Archaea and Eukaryotes both undergo DNA replication and protein synthesis the same mechanism. Both of them posses closely related genes and several metabolic pathways, including the enzymes in transcription and translation.
