Answer:

The water vascular system of echinoderms (B) functions in locomotion and feeding.

Which of the following combinations of phylum and description is correct?   (C) Platyhelminthes—flatworms, gastrovascular cavity, no body cavity

Explanation:

Echinoderms are marine animals. They have a water vascular system that make them able to move (locomation), respiration and food and waste transportation. This system is full of different canal along the body.  

Echinodermata has not a radial symmetry as a larva, in fact it has a bilateral symmetry and coelom present. When it comes to Nematoda, they are roundworms and have a pseudocoelomate. Finally, porifera has a gastrovascular cavity and no coelom.

Arrange the events to describe how an earthquake
Aneli [31]

The correct chronological order in which an earthquake occurs.

1. The plate suddenly move.

2. Stored energy is released in the form of seismic waves.

3. Due to the movement in the mantel, compression goes on increasing.

4. The earth surface vibrate.

When the plate move from the surface of the earth, all the stored energy present in it is usually released in the form of seismic energy waves and due to the movement in the mantel, compression goes on increasing, then after , the earth surface vibrate.

Hope it has helped:-)

A doctor is studying a disease where the nucleus of a cell does not grow properly. What do you think would happen to the cells'
Drupady [299]

Answer:

The cell would fail to function. It would likely fail to properly replicate DNA properly or transcribe genes.

Explanation:

The nucleus holds the genetic information, the DNA. If the nucleus does not grow properly, the DNA might not fit or be properly organized inside. This would mean DNA replication could not proceed as normal, and the DNA might not even be able to fit inside the nucleus!

The cell would also struggle to properly transcribe the DNA if the nucleus is not fully formed. DNA acts as a template for mRNA transcription, which directs protein synthesis. The cell will very quickly die if there are inaccuracies in protein synthesis due to mRNA not being adequately synthesized.

Compared to cnidarians, bilaterally symmetrical animals have _____ nervous systems.
Natasha_Volkova [10]

Compared to cnidarians, bilaterally symmetrical animals have a central nervous system.

<h3>What do bilaterally symmetrical animals have?</h3>

• Bilaterally symmetrical animals have "heads" and "tails" (front and back), front and rear (back and abdomen), and left and right sides. All true animals are bilaterally symmetrical, except those with radial symmetry. The

• longitudinal nerve cords, usually in 3-5 pairs, extend posteriorly from the brain. They are connected by transverse commissures, with smaller lateral nerves extending from the cords. The peripheral plexus arises from the lateral nerve.

<h3>Do bilaterally symmetrical animals have diffuse neural networks?</h3>

Neural networks consist of interconnected neurons that lack brains or some form of cephalization. Organisms with bilateral symmetry are usually associated with neuronal compression and, in a more advanced form, with the central nervous system, whereas organisms with radial symmetry are associated with neural networks.
