Helicase molecules is active first in DNA replication.  DNA helicase are enzymes capable of unwinding duplex DNA to provide the single- stranded DNA templates that are required in processes such as replication and recombination.all helicase separates the strands  double mix helix using energy derived from hydrolysis nucleotide.

Natalka [10]

Answer:

The correct answer is D.

Explanation:

The Amoeba Proteus example given in the question describing its engulfing smallar organism and digesting them is an example of a proces named "Phagocytosis". These cells are called phagocytes and the process can be used for both feeding purposes or defensive purposes by various cells. I hope this answer helps.

Why is it important for ectoparasites to stay undetected by their host?
melomori [17]

Ectoparasites cause diseases in humans and animals, so to know the format of detecting it we need to know that ......

<h3>Ectoparasite</h3><h3 />

Parasitism is defined as an interaction where a parasitic organism obtains resources through one or several host individuals, causing damage and reducing its fitness. The endoparasite is a type of parasite that lives inside the host's body (from the Greek endos, inside), while the ectoparasite is one that lives on the external surface of its host (from the Greek ectos, outside). Thus, the ectoparasite does not need to lodge inside the host organism to feed, presenting a partial metabolic dependence. Some examples of ectoparasites are:

  • Lice
  • Ticks
  • and Fleas.

<h3>Strategies of ectoparasites</h3>

Each parasite has particular strategies and adaptations used to extract nutrients from their hosts. In ectoparasites these adaptations can often be seen as changes in the oral apparatus, allowing them to penetrate the skin surface and feed on the host's nutrients. Scabies is a skin disease caused by the ectoparasite <em>Sarcoptes scabiei</em>. In order to obtain nutrients for its survival, the parasitic organism burrows into the skin of the host, unlike ectoparasites such as the louse, which pierce the surface and only insert its mouthparts to extract food.

<u>With this information we can say that the </u><u>ectoparasites </u><u>adapt to the host so that it is </u><u>not noticed </u><u>and for a better </u><u>absorption of nutrients </u><u>from the host, they remain </u><u>undetectable</u><u> not to be </u><u>removed</u><u>, so that they are not </u><u>disconnected</u><u> from their </u><u>food source</u><u> as they are in the vast majority visible to the eye.</u>

what is thought to be the correct sequence of these events, from earliest to most recent, in the evolution of life on earth? ori
Montano1993 [528]

The correct sequence of these events (origin of mitochondria, origin of multicellular eukaryotes, origin of chloroplasts, origin of cyanobacteria, origin of fungal-plant symbioses), from earliest to most recent, in the evolution of life on earth is 4, 3, 1, 2, 5.

The transition to eukaryotic cells seems to have taken place in the Proterozoic Era, around 1.2 to 1.5 billion years ago. Nevertheless, the latest genetic studies propose the divergence of eukaryotes from prokaryotes nearer to 2 billion years ago.

Margulis suggested the mechanism of endosymbiosis, to describe the origin of mitochondria as well as chloroplasts from persistent living prokaryotes. In accordance with this idea, a bigger prokaryote engulfed or enveloped a smaller prokaryote around 1.5 billion to 700 million years ago.
