The following is most likely true of a core sample of old, mature soil as D. It consists of several layers of different kinds of materials.
<h3>
What is mature soil?</h3>
Soil is bodily mature while it attains a moisture stage that permits it to interrupt into clumps measuring 1–10 mm. (With a better moisture content, the soil sticks to the tillage implement; with a decrease moisture content, the soil breaks into big clumps and clods.)
A soil can not be more mature than the oldest bushes developing in it. It can not be older than the substances wherein it paperwork or the panorama on which it's far found. Soil scientists paintings with geologists to decide how vintage the panorama is, and the way lengthy the figure substances had been there.

In immunology two types of immune response are described depending on whether there is prior contact with the antigen.
• At this first contact, only lymphocytes with receptors specific to the antigen in question are stimulated and lead to the production of antibodies capable of neutralizing it. The lymphocytes capable of recognizing a specific antigen are very few and the production of antibodies - of low intensity and limited duration - is detectable only after a period of latency of several days. This is called the primary response. The specificity of the resulting seropositivity, however, makes it possible to detect contamination (seroconversion).
• Upon re-contact with an antigen that has already triggered a primary response, specific antibody production is found to increase rapidly after a short latency period. The secretion of IgG then reaches levels much higher than those observed during the primary response, while that of IgM is of the same order. This early and intense response, called secondary response, most often results in the destruction of infectious agents before any clinical sign.
• Many centuries before the discovery of microbes, it was noted that people who developed a contagious disease without death were then specifically immunized against the disease, without being protected against others.
• The ability to react appropriately to an already received stimulus supposes the existence of a memory. The immune memory is based on the existence of memory B and T lymphocytes, resulting from the clonal expansion due to the first contact with the antigen. Their lifespan is significantly higher than that of other lymphocytes and their high reactivity gives its rapid and intense character to the secondary response.
Answer:
Answer is option B - "I should shower rather than take a tub bath."
Explanation:
Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;
- Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
- Avoid swimming or taking a tub bath, but can take showers.
- Dressings over the incision should be removed daily and keep the wound area clean.
- Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
- Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
- Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.
The condition that distinguishes animals and plants from inorganic matter, including the capacity for growth, reproduction, functional activity, and continual change preceding death.
This is the definition of life.
