Answer:

Sea anemones are marine predatory animals. They are like a terrestrial flowering plant due to their colorful appearance. They are coming under the phylum cnidaria.  

Sea anemones are found in different forms called a polyp. It has a columnar trunk, on the top of the trunk an oral disc and centrally placed mouth. The mouth is surrounded by tentacles.

Sea anemones have a gastrovascular cavity that serves as stomach. This cavity has one opening both meant for mouth and anus.

Sea anemones are capable of changing their shape and lives on the mud, holding it by pedal disc.

Polychaetes are segmented worms. Each segment of the body bears parapodia. It helps them in locomotion. There are different types of polychaetes, tube-dwelling polychaetes are one of them.

Tube - dwelling polychaetes make tubes to protect their soft bodies.  

They don't have parapodia but some special anterior structures for feeding. The tubes are made from calcareous materials.

Secondary amenorrhea occurs in times of extreme stress or weight loss (such as anorexia). Female soldiers have experienced secondary amenorrhea when they have gone to war or have become prisoners of war.

What is the purpose of the lab?
Alex787 [66]

Explanation:

Accordingly, the introductory physics laboratories have the following purposes and goals:

1. To provide an experimental foundation for the theoretical concepts introduced in the lectures. It is important that students have an opportunity to verify some of the ideas for themselves.

2. To familiarize students with experimental apparatus, the scientific method, and methods of data analysis so that they will have some idea of the inductive process by which the ideas were originated. To teach how to make careful experimental observations and how to think about and draw conclusions from such data.

3. To introduce the methods used for estimating and dealing with experimental uncertainties, including simple ideas in probability theory and the distinctions between random (statistical) and systematic "errors." This is essential in understanding what valid conclusions can be deduced from experimental data and that, properly obtained, these conclusions are valid, notwithstanding the uncertainty of the data.

Which of these is ATP?
Pepsi [2]

Answer:

The correct answer is <em>A molecule consisting of three phosphate groups, ribose, and adenine.</em>

Explanation:

ATP means adenosine triphosphate, and it is a molecule which has a very important role in energy transfer in the cells.  As its name says, it is composed by:

- adenine: a purine base, which is also a component of nucleic acids.

- ribose: a 5-carbon sugar (in contrast to deoxyribose, ribose has a -OH group in place of a -H group in carbon 2)

- three phosphate groups

Notice that adenine bonded to the ribose is called adenosine.
