Answer:
Explanation:
Hepatitis B is a viral infection. This infection attacks the liver and is a source of acute and chronic disease. It is transmitted by body fluids like blood, and can also be transmitted by sex if one is infected, or by childbirth by the infected mother. It is also transmitted if people are sharing needles or syringes. So prevention would be done by practicing safe sex, testing ourselves before we have kids, and using clean syringes and needles that nobody used before us. Besides these, there is a vaccination that is safe and works.
Most don't report symptoms when infected. But some can experience illness for several weeks and their skin starts yellowing along with the eyes, urine becomes darker, nausea and fatigue along with vomiting or abdominal pain.
Answer:
The correct solution is Option d (when rocks develop joints or fractures
).
Explanation:
- Porosity is observable from descriptive samples taken. The drawbacks of receivable dams are that this is impossible to make true reflection temperature measurements, specific side-wall concrete samples while being often valuable can also result in poor coverage as well as dependence on log-derived porosity seems to have become the standard.
- As porosity rises, too much wind needs to pass further through most of the shelterbelt, which would be to say the less significant decrease in wind direction.
Some other available scenarios have no connexons with the particular circumstance. So this seems to be a reasonable option.
Answer:
c. Graded beds are evidence of a decrease in current velocity during deposition whereby coarse sediments settle out first, followed by finer sediments as the velocity decreases over time.
Explanation:
Answer:
space
Explanation:
As air gets warm, the air molecules have more energy and move around more, taking up more space. As the warm air expands, it becomes less dense than the cold air, so rises up and floats above the cold air.
Uluru is located in Australia and it's formation took place over 500 million years ago.It is composed of sedimenatry rocks called arkose.Rapid erosion of the mountains made materials that were deposited under the sea which formed uluru.Uluru is made up of very weldege rock.The top is flat and sides are grooved due to the process of weatheration.The red colour is due to the rusting of iron.The rock reacts with water and oxygen.
