C) Gastropods

Explanation:

Radula is the scraping and feeding organ of Gastropods.
Since giant triton uses a radula to saw into the sea star, it is obviously a Gastropod.
Charonia tritonis or giant triton are large sea snail.
They belong to class Gastropoda under phylum mollusca..
These are natural predators of starfish and other small molluscs.
Like other molluscs these are also soft bodied animals and have large shells.

In eukaryotes, there are two main types of DNA organization present in chromosomes:

kupik [55]

Answer:

The two main types of DNA organization present in chromosomes are the extended DNI and the condensed DNI

Explanation:

In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNA molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA.

DNA associated with histones is called chromatin. Histones are responsible for packaging DNA molecule, and the fundamental unit of packaging is known as a nucleosome. As chromatin must be condensed, nucleosomes generate regular structures between themselves forming a chromatinic fiber, in which DNA is very condensed. A superior level of condensation is the structural ringlet-shaped domain. At this level, a chromatinic fiber is folded and a protein is responsible for keeping joined the two regions of DNA that form the ringlet. The next condensation level is the rolling of the ringlet-shaped domain composing the chromosome. The typical chromosome in the metaphase is formed by two chromatids joined by a centromere. Each chromatid is composed of a sequence of chromatin ringlets domains. In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state, known as extended DNA. When cellular division is about to happen, chromatin begins to condensate. At the beginning of the prophase, DNA is condensed in a well-defined chromosome formed by two sisters chromatids.

Is balamuthia mandrillaris a public health concern worldwide?

True [87]

Balamuthia mandrillaris is an amoeba that was discovered in 1986 in the brain of the baboon that dies in San Diego Wild Animal Park. This can be found in the soil and water, therefore it is freely living. It is known to cause the neurological condition known as granulomatous amoebic encephalitis. In a study published by National Center for Biotechnology Information, it has a case fatality rate of >98%. Majority of this case can be found in warmer regions that affects individuals mostly of Hispanic origin. Documented cases had been reported from the Latin Americas in significant number, followed by the United States, Asian regions and some in Europe. However, a specific number of cases worldwide may never be known due to the following factors: lack of awareness, poor diagnosis and a poor public health system.

It is still yet to be known if its a serious public health concern worldwide.
