Ans.1.

Cnidarians are lower eukaryotic organisms that include aquatic invertebrates, such as jelly fish, hydra and corals. These organisms show two types of body plan, medusa and polyp, both of which show radial symmetry.

Sponges belong to phylum Porifera that includes simpler asymmetric, marine organisms, with no body plan.

Thus, the correct answer is option). 'they have a medusa body form.'

Ans.2.

The corals are marine organisms that belong to phylum Coelenterata. Corals are often called as medicine chests of the sea as they are used for the treatment of various diseases, such as cancer, ulcers, and cardiovascular diseases.

Corals are easy to grow and provide a cost-effective way for collection, screening, and production of new medicines. So, there is an advantage of using corals to treat cancer and other disease as it is less expensive than drugs, which are synthetically produced in labs.

Thus, the correct answer is option). 'it is often less expensive to use than chemicals produced in a lab.'

Ans.3.

Both sponges and corals are used for the treatment of various diseases. For example, chemicals from bryozoans, such as  bryostatin 1 are used for the cancer treatment in humans. Likewise, corals are also used for the treatment of cancer.

Thus, the correct answer is option). 'both are a source of chemicals that may be used to fight human diseases, such as cancer.'

Ans.4.

Most of the sponges do not release their eggs into the water, until they hatch. After fertilization, the zygote remains attached to the mother body and develops into larva, having cilia within its outer layer of cells. The cilia function in movement of larva and enable the larva to swim.

Thus, the correct answer is option). 'helping the larva swim out of the adult sponge.'

Show the energy of Oxidation of two mole pyruvic acid.
DerKrebs [107]

Answer:

Methanesulfinic acid (MSIA) is an important intermediate in the oxidation of dimethyl sulfide (DMS) in the marine boundary layer. The oxidation of MSIA by ozone in the gas phase to form methanesulfonic acid (MSA) was investigated using theoretical calculations in this paper. Three pathways can be found for the reaction of MSIA with ozone. The highest energy barrier is 13.02 kcal mol−1 in the most favorable pathway. By comparing the reaction rate of MSIA + O3 with that of MSIA + OH, it can be concluded that the oxidation of MSIA by O3 to form MSA is of minor significance relative to its oxidation by OH radical in the gas phase. This study can provide some information for the theoretical and experimental studies in the significantly heterogeneous and aqueous-phase oxidation of MSIA by O3.

How do the kidneys maintain homeostasis in the body?
andreev551 [17]
The kidneys remove waste products from metabolism such as urea, uric acid, and creatinine by producing and secreting urine. Urine may also contain sulfate and phenol waste and excess sodium, potassium, and chloride ions.

Describe an arctic summer
aev [14]
<span>Summer temperatures in the Arctic remain cool, fluttering around zero in many places, from June through September. In fact, Arctic residents must frequently heat their homes all year long. Neighbourhoods near the sea tend to remain close to 0°C throughout the summer, but inland areas, particularly in the south, regularly reach 7°C–13°C, and hardly as much as 20°C. One reason for the opposition is that the sea ice, which gradually melts, consumes much of the sun's energy, giving little to heat the air over it.

Hope this helped! :)</span>
