Answer:

3. Rocks erode and sediment is deposited.

4. No sediment is deposited over a long time.

Explanation:

An unconfomity is a break in stratigraphic record of a place usually as a result of non-deposition or erosion.

In a sequence of sedimentary rock strata some surfaces called unconformity surfaces gives clues about the depositional history of a particular place. During an unconfomity, there is usually no sediment deposition and when deposition resumes, the underlying rocks and the new ones will not share the same attribute especially by age. Unconformity can also be as a result of erosion of a sequence.

In the case of non- conformity, a sedimentary rock is deposited above an igneous or sedimentary rock. Option 5 is a simple example of an igneous intrusion called a sill. It is not unconformity.

Option a

Explanation:

The front of the white paper packet of the OSL dosimeters may be color-coded to facilitate correct usage and placement of the badge on the body of occupationally exposed personnel.

OSL dosimeters are recently developed and are of high quality than thermoluminescent dosimeters. It is used to monitor patients health status. Furthermore, it is very sensitive to any change or drop in reading. it give accurate readings even at 1 mrem for both gamma ray photos and X-rays.

Answer: wind power, As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitat for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.

Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

A cell cycle is a series of events that takes place in a cell as it grows and divides. ... The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle. mark brainliest plzz

Sepsis List each type of sepsis, identify causes of each, list prevention techniques, and compare and contrast each type.

zheka24 [161]

Sepsis refers to a life-threatening issue of the infection. It takes place due to the immune reaction to the bacterial infection that invades the blood. It usually results in injury or organ failure. The following are the kinds of sepsis:

1. Lung sepsis (Pneumonia)

2. Urinary tract sepsis (Kidney infection)

3. Gastrointestinal sepsis (Abdominal infection)

4. Bloodstream sepsis (Septicemia)

The causes of sepsis: Any infection can result in sepsis if not treated properly. The infectious agent passes via the blood and leads to sepsis of any parts of the body. It can be caused due to bacterial infections, fungal infections, old age problems, drug-resistant bacteria, and a weakened immune system.

Some of the preventive measures for sepsis are as follows:

1. Taking vaccinations

2. Practice good hygiene

3. Proper care for wounds

4. Safe water and sanitation

5. Eating probiotics

6. Proper treatment for infections

Lung sepsis: Also known as pneumonia, is an infection in the lungs. It is caused by fungi, bacteria, and viruses. It is a hospital-acquired infection. Some of the symptoms of pneumonia sepsis are fever, cough, sweating, muscle pain, and chest pain. It is treated with the help of antibiotics.

Urinary tract sepsis: It causes urosepsis. It majorly affects women and men in ICU. The symptoms are a pain in the lower back, fever, vomiting. nausea decreased urine output. The treatment for urinary tract sepsis is antibiotics, apart from that intravenous fluids, oxygen, and other medications are taken.

Bloodstream sepsis: It is also known as blood poisoning. It is life-threatening and can spread to different parts of the body. The symptoms include dizziness, low blood pressure, dehydration, confusion, and joint pains. This is also treated with the help of antibiotics administered intravenously.

Gastrointestinal sepsis: It is also known as peritonitis. It is caused due to the presentation of an infection into the sterile peritoneal environment due to organ perforation, and may also result due to other irritants like foreign bodies, gastric acid from a perforated ulcer, bile from a lacerated liver or from a perforated gallbladder. The symptoms of the condition are abdominal pain, fever, bloating, and loss of appetite, low urine output, diarrhea, and thirst. It is also treated with the combination of antibiotics.
