Hello. You forgot to enter the necessary data for this question to be answered. The data are shown in the figure attached below:

Answer:

Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins.

Explanation:

Red-capped Robin is the group of Robins that share a more recent common ancestor with the Norfolk Island robins, this can be seen by the degree of genetic similarity between these two species, since the Red-capped Robin has 98.2% of genetic similarity .

When two species have the same common ancestor, these species have great genetic similarity and the more recent this ancestry is, the greater the genetic similarity between the species.

Which of the statements describes characteristics of eukaryotic cells but not of prokaryotic cells? O two or more linear chromos
gtnhenbr [62]

O relatively large genome, dynamic cytoskeleton, compartmentalized metabolic processes

Explanation:

Eukaryotic cells also contain other membrane-bound organelles such as mitochondria and the Golgi apparatus, and in addition, some cells of plants and algae contain chloroplasts. Unlike unicellular archaea and bacteria, eukaryotes may also be multicellular and include organisms consisting of many cell types forming different kinds of tissue. 

DNA is located in the nucleus, the mitochondria and the chloroplasts (occuring only in plants and some protists). The nucleus contains most DNA. It is present in this compartment in the form of linear chromosomes that together constitute the genome.

Eukaryotic cells generally use aerobic respiration – requiring oxygen – to produce usable energy called ATP from glucose molecules. ... Prokaryotic cells, on the other hand, tend to use anaerobic respiration – not requiring oxygen.

Why is it important to elevate the anthers.
Rasek [7]
The anthers are in the elevated position so that the pollinators will be attracted towards it, and that the pollen grains are easily carried away by the agents of pollination. The proper pollination is essential for the process of fertilization.
Hope this helps:)

After first exposure to an antigen, about how long does it take for antibodies to reach a detectable level?
Salsk061 [2.6K]

After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.

Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.

At times, we can see an increase in antibodies for one disease, for example, <em>Lyme disease</em>, in the presence of <em><u>non-Lyme disease antigens.</u></em> This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.

As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.

After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while <u>general-purpose antibodies will return to a base value. </u>
