cricket20 [7]

The right answer is Lichen.

In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.

Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .

1. What does your body do to infected cells?
Shkiper50 [21]

Answer: White blood cells form to fight off cell infections.

Explanation:

1. Your body produces white blood cells which fight against infected cells, depends on what type of cell it is and how infected it is.

2. The immune response to a viral infection is primarily generated by a type of white blood cell called lymphocytes; cells that are mostly localized in ‘lymphoid tissues’ such as the lymph nodes or tonsils. However, the number of lymphocytes that can recognize and react against any individual type of virus is initially very small. This is particularly true for a novel virus such as SARS-CoV-2, which people have never encountered before. In order to produce an effective immune response, the small number of lymphocytes that can recognize a virus must become more abundant. Even though lymphocytes proliferate quickly it still takes several days before there are sufficient cells available to fight back against the infection. During this period the virus may also be spreading rapidly, so there is a race between the virus and the immune system that may determine the final outcome, in terms of recovery.

jeka94

Answer:

Species A: 2

Species B: 56

Species C: 162

Explanation:

Codons are sequence of 3 purine or pyrimidine bases that codes for amino acids. Each codon in mRNA eventually binds with anticodon in tRNA during protein synthesis and gets translated into their respective amino acids. Hence, the number of amino acids in each of the species represents the minimum number of codons in each species.

<em>Therefore, species A with 2 amino acids will have a minimum codon length of 2, species B with 56 amino acids will have minimum of 56 codons while species C with 162 amino acids will have minimum codon length of 162.</em>
