Answer: ADAPTIVE COLORATION

Explanation:

Colour and colour patterns play an important role in adaptations of animals. Such adaptive coloration is due to the presence of pigments in cells called CHROMATOPHORES. These cells are involved in coloration and color change which helps an animal to look like another animal to stay protected from predators.

Adaptive coloration may be grouped into :

--> WARNING COLORATION: some animals display bright colours and patterns that announce their presence rather than conceal it. Example is the yellow and black stripes of yellojackets and other wasps which have very painful stings.

--> MIMICRY: colours and patterns are used extensively by mimics. For example, the foul-tasting Actaea butterfly and the poisonous African monarch are mullerian mimics. They resemble each other closely because they have similar colouring and patterns on their bodies.

--> CONCEALING COLORATION: This is used in camouflage. It helps an animal to remain unnoticed by the predator. Certain animals change the colour of their body surfaces to match their environment and so escape detection.

Complete question:

Which of the following statements is NOT correct about the flatworms?

A. There are three complete tissue layers.

B. Flatworms may be either free-living or parasitic.

C. Flatworms have a sac body plan, with only a mouth and no anus.

D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.

E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.

Answer:

D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.

Explanation:

Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.

Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.

These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.

Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.

A diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

During egg formation in the ovary, Primary oocyte (diploid) having 46 chromosomes undergoes meiosis I to form one secondary oocyte and one first polar body.

Both the secondary oocyte and one polar body are haploid having 23 chromosomes.  Both daughter cells then undergo meiosis II, the first polar body divides to give two polar bodies and the secondary oocyte divides by meiosis II to form one ovum.

Therefore, during egg formation in the reproductive system, a diploid cell (a primary oocyte) undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

You can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell. The cell membrane alone cannot provide the required rigidity or strength. All living organisms are composed of cells.

Small shrubs are the kind of organisms that start secondary succession after a forest fire. The correct option is A.

Thus, the term "secondary succession" describes the ecological recovery process that follows a disruption like a fire. Small shrubs have developed survival strategies that enable them to swiftly colonize damaged environments.

They have the capacity to emerge from subterranean structures once again or to create seeds that will take root in newly accessible sunshine and nutrients. Due to their quick growth and capacity to keep the soil stable, these shrubs facilitate the establishment and flourishing of other plant species.

Thus, the ideal selection is option A.

The immunostimulants act as those molecules that are found on the outer surface of the microforms.

The microorganisms are those organisms that can only be seen through the microscope and include the bacteria, the protozoa, the algae, and the fungi.

The virus is not considerd to be living and has a single cell or may form a colony of cells. The unseen microbial life is scripted in the 6th century BC. As these microorganisms have a single-celled life they are more diverse.

The presence of the immunostimulants on the body of the micro organs tells about the outer surface of these microorganisms.

Most likely the consequence of this type of mutation is The gene would result in a shorter protein, possibly causing problems. Thus, option "A" is correct.

Mutations are the change in the nucleotide sequence of genetic material due to substitution, deletion or insertion of the nucleotides leading to changed protein.

There are many types of mutations.

If a mutation causes no effect on the protein produced, it is known as the silent mutation. It is usually due to substitution of one nucleotide with the same type of nucleotide as in glycine glycine mutation.
