During an incisional breast biopsy, <span>whereby incision made
into lesion and small portion of lesion taken out.</span> An incisional biopsy is a process in which a small part of tissue is in
use to classify the conformation of a lesion or irregularity.
There are four selections for attaining
a tissue specimen.
<span>·
</span>A fine needle aspiration is the pretentious, least aggressive test and
uses the smallest needle to simply remove cells from the abnormality. This is
not always adequate to obtain a diagnosis, depending on the area to be
biopsied.
<span>·
</span>A core needle biopsy removes not only cells, but also a small amount of
the surrounding tissue. This delivers extra data in assistance in the
identification of the lesion.
<span>·
</span><span>An incision biopsy proceeds out even more adjoining tissue. It proceeds
out some of the abnormality but not all. The doctor will cut into the lesion
and remove only a portion of it. If the lesion is found to be cancerous,
further surgery may be desirable to eliminate the whole irregularity.</span>
Answer:
Hemoglobin
Explanation:
Hemoglobin is the protein present in the red blood cells of the blood. The protein hemoglobin serves as oxygen carrier and binds to the oxygen in lungs. As blood flows from lungs to the different body parts, hemoglobin serves to carry oxygen from lungs to various cells of the body. At higher partial pressure of carbon dioxide and lower pH of cells of the body, the hemoglobin releases oxygen and thereby, serves as oxygen carrier.
Slow reproduction process is a disadvantage of sexual reproduction. So option A is correct.
Sexual reproduction is much slower than asexual form of reproduction and the meiosis process is much longer and complex than mitosis. The process of sexual reproduction depends on the fertilization and zygote formation which are time consuming processes. This longer duration of reproduction process leads to lesser number of individuals in the population. In this case there may be instances of producing only one organism per year and if by chance no offspring is produced for certain number of years can lead to extinction of the species.
Answer;
Transport substances throughout an organism.
The cytoplasm in a single celled organism and the circulatory system in a human both transports substances throughout an organism.
Explanation;
Circulatory system carries blood to the cells of the body to distribute oxygen and nutrients and pick up cell wastes. It consists of the heart, blood vessels and the blood.
Cytoplasm in a single cell helps in the transport of materials such as nutrients, through out the cell.
