Answer:
A Tongue-shaped structure called radula for grasping food --> MolluscaFleshy lobe-like structure called parapodia --> AnnelidaSpongin fibers or spicules for support ---> PoriferaExplanation:
Radula: This is an organ used in feeding by mollusks. It constitutes a highly developed feeding organ. The radula has is conformed of small teeth-like structures located in rows. Lateral teeth vary in shape and size. The movements of the radula during feeding are complexes acting as a scratcher on the surface to get the food.
Parapodia: These are characteristic lateral appendixes that emerge and extend from each of the body segments of invertebrates such as polychaetes. The typical parapodium is a fleshy prolongation more or less laterally comprised and is composed of a superior branch (notopodium) and an inferior branch (parapodium).
Spicules: Sponges (Poriferous) skeleton is composed of calcium carbonate and siliceous micro-structures called spicules. Their morphology is so varied that it is used in taxonomy for identification and classification.
There are different kinds of spicules:
- Monoaxonic spicule: needle-shaped, straights or curves
- Tetraxonic spicules: they have four prolongations
- Triaxonic or Hexaxonic spicules
- Poliaxonic spicules
Two terms can be applied to any of these spicules kinds:
- Megaspicules: They are elongated and compose the main architecture of the sponge skeleton
- Microspicules: Variable in shape and size, with ancillary functions
Sponges have few predators because of the spicule structures and their high toxicity. Many of them are capable of perforating soft tissues and producing urticant substances.

Which of the following is true about nucleic acids?
Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.
Nucleic acids are usually insoluble in water and are used for long term energy storage.
Glucose, cellulose, and starch are examples of nucleic acids found in most cells.

Answer:
Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids. Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.Explanation:
DNA and RNA are both made up of chains of nucleotides. They are responsible for holding, transmitting, and translating genetic information into proteins.
Nucleotides are made up of a 5 carbon sugar, (DNA is deoxyribose, RNA is ribose), a phosphate group, and a nitrogenous base. They are linked together by phosphodiester bonds. The sequence of nucleotides makes the DNA and RNA sequences unique and determines the structure and function of the encoded proteins

Both DNA, which stores genetic information and encodes protein sequences, and RNA, which is involved in the direct production of proteins, are nucleic acids.
Nucleic acids always consist of a five-carbon sugar, a nitrogenous base, and one or more phosphate groups.

If we bring cheesy pizza into the classroom and placed it at the door, is that the high or
low concentration?
a. After about 10 minutes, would the molecules fill up the room?
b. If so, is that the molecules moving from high to low concentration or low to
high? Explain your choice
Answer:
a. yes
b. high concentration.
Explanation:
Yes, molecule move from high concentration to low concentration by the process of diffusion.
What is diffusion?
Diffusion is a process or movement of molecules where they move from high concentration to low concentration. It is a passive movement. Molecules move downhill from their concentration gradient.
Since, for transfer of this molecules no energy is required it is called passive transport. In plants diffusion is a important process for transfer of gases.
In animals, it plays a important role for transfer of gases such as oxygen and carbon dioxide. If we bring cheesy pizza into the classroom then the aroma of the molecules move down the concentration gradient.
Therefore, Yes, molecule move from high concentration to low concentration by the process of diffusion.

Marine ecosystems support a(high, low) diversity of life,
largely due to (constant unchanging conditions, a lack of natural predators, the variety of environments) throughout the ocean.
Answer:
high diversity, variety of environments
Explanation:
To this day, scientists are still discovering new marine animals. This is because of all of the different environments in the ocean, Some animals exist in tropical areas, others in freezing cold water. Some animals even exist solely in high pressure areas that are hundreds of meters below the surface. There are even organisms older than dinosaurs living in the ocean.

Answer: All of the above
Explanation:
Which statement best describes the end result of this process? a New molecules of mRNA are transcribed from the DNA molecule. b The new DNA molecules are made from opposite DNA strands so they are not identical. c A protein molecule is synthesized from the code in the DNA molecule. d Two new DNA molecules are formed, each identical to the original
Answer: c. A protein molecule is synthesized from the code in the DNA molecule.
Explanation: This shows the steps surrounding the central dogma of molecular biology stating that the genetic material, DNA contains the needed information and instructions for creating a protein, which are copied by RNAs. As such it follows that DNA is transcribed into RNAs which are in turn translated into proteins.
