Answer:
The correct answer is ''an infection that migrates via the bloodstream.''
Explanation:
An infection is the invasion of pathogenic germs or microorganisms that reproduce and multiply in the body causing disease. Bones, like any other organ or tissue in the human body, can become infected. Osteomyelitis is a bone infection caused by bacteria, mainly Staphylococcus aureus, although in some cases it can also be caused by fungi. The infection can start in another part of the body and spread to the bone through the bloodstream. In this case, it usually occurs at the ends of the leg and arm bones in children and in the spinal column (vertebrae) in adults, especially the elderly.
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.
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.
A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control group.
The main arctic animals which will be affected by climate change are polar bears, seal, seabirds, and walrus.
Polar bears: Sea-ice cover at summer may be completely loss and this inhibits polar bears traveling from region to another to give birth — making the survival of mothers and cubs to be vulnerable.
Seal: Seal species are living mainly on ice and with the climate changing, ice cover also reduces — creating a not so comfortable environment for seal. They use sea ice as a feeding ground, birth place and a place where for raising their young, as well as for resting.
Seabirds (auks and gulls): They eat fishes and scavenge on top of sea ice, so when sea ice reduces so as their source of food and population.
Walrus: Uses sea ice as a feeding ground and source of food is on the sea floor while using sea ice as a diving platform. So any loss of sea ice cover, also affects their way of feeding and eventually, their population.
Overall, melting of ice affects salinity and temperature of surface waters, thereby affecting other marine life.
