An Asian clam, a fresh water creature, is usually less than 50 millimeters.
It tends to be small and light-colored, with a shell ornamented by distinct, concentric sulcations, anterior and posterior lateral teeth with numerous fine serrations. It resides in brackish to freshwater rivers, lakes, streams, canals and reservoirs. This creature lies on or is slightly buried in materials such as sand, silt, or gravel-bottomed places. It usually prefers running water with high oxygen levels and has no tolerance for polluted or near-freezing water.
Answer:
secondary structure
Explanation:
Alpha helices and beta sheets are two main structural forms in secondary structure of proteins. This structures are formed spontaneously. The next step of protein structure formation is folding into tertiary three-dimensional form.
In diseases such as CJD and kuru, protein prion is changed in structure. It is not known how degeneration of priones protein structure occurs, but it can lead to neurodegenerative diseases which can even be fatal.
Priones are also known as proteinaceous infectious particles.
Answer:
A. No, because budding is a type of asexual reproduction.
Explanation:
Asexual reproduction is the process where an organism makes a copy of itself by itself. It does not require a mate to make offspring.
The offspring are genetically identical to the parent.
Budding is a type of asexual reproduction where a small outgrowth of the parent breaks off to become a new organism.
Embryo development is usually only discussed in the context of sexual reproduction, where two gametes fertilize one another and a new organism that is genetically different to either parent is formed.
