Frost wedging occurs when water seeps into a crack in a rock, freezes, and causes the crack in the rock to widen. true or false?

Answers

Answer 1
Answer: It is true that frost wedging occurs when water seeps into a crack in a rock, freezes, and causes the crack in the rock to widen.
Answer 2
Answer:

The statement is - True.

The frost wedging is one of the processes that contribute to the physical weathering of the rocks. Basically, if the rock has a crack, water manages to get into that crack. On the places where there's winters and the temperature drops bellow zero, the water in the crack of the rock freezes. Because the ice is expanding, it creates a lot of pressure inside the rock. Because of this pressure, the rock eventually cracks into two or more pieces. There have even been recorded cases where this form of weathering resulted in explosion of the rocks, where the pressure inside the rock was so big, that it has literary exploded, but that is very, very rare.

Which quadrilaterals always have consecutive angles that are supplementary?

Answers

Answer:

The quadrilaterals which have supplementary consecutive angles are called Parallelogram.

Explanation:

  • A parallelogram is a type of quadrilateral which has two parallel sides on each opposite sides which are equal and the opposite angles in a parallelogram are also equal.
  • The consecutive angles of a parallelogram are supplementary meaning that the sum of the consecutive angles in a parallelogram is equal to 180 degrees. The overall sum of all the angles in a parallelogram is 360 degrees as it is a quadrilateral.
  • The diagonals of the parallelogram bisects each other and divides the parallelogram into equal halves.

Non-cardiogenic pulmonary edema is the most profound effect from exposure to

Answers

Alcohol and drug abuse, certain medications, and viral infections may lead to Non-cardiogenic pulmonary edema. Exposure to either of these could contribute or increase the chances getting Non-cardiogenic pulmonary edema.

Answer:

Non-cardiogenic pulmonary is due to anticancer therapy.

Explanation:

Noncardiogenic aspiratory edema (NCPE) is an uncommon and less well-conspicuous pulmonotoxic disorder of anticancer treatment than pneumonitis/fibrosis.  

NCPE is a clinical disorder portrayed by concurrent nearness of serious hypoxemia, respective alveolar invades on chest radiograph and no proof of left atrial hypertension/congestive cardiovascular breakdown. The analysis of medication-related NCPE depends upon recorded rejection of any irresistible, metabolic, or disease-related causes.  

The time closeness to treatment with medications that are known to hasten NCPE, any first scenes of influenza-like side effects during past chemotherapy courses and conceivable reaction to corticosteroids may further help such a finding.

Malignancy remedial specialists plainly connected with NCPE are cytarabine, gemcitabine, and interleukin-2, just as all-trans retinoic corrosive in intense promyelocytic leukemia patients, while a couple of different mixes have infrequently or every so often been ensnared. The pathophysiology of lung damage in medication incited NCPE stays misty.

Scientists today can use many experimental methods to study evolution. Which method was developed after Darwin’s time?DNA comparisonsobservationsfossilsexperimentation

Answers

DNA comparisons was developed after Darwin's time and have become an important method for studying evolution.

While Darwin was able to make observations of variation and adaptation in different species, he did not have access to the genetic information that DNA provides. It wasn't until the discovery of the structure of DNA in 1953 that scientists began to explore the use of DNA in studying evolution.

Since then, DNA sequencing and comparisons have become increasingly important tools in the study of evolutionary relationships and processes.

In science, DNA comparison is a ground-breaking technology. It has given researchers the ability to compare and contrast DNA samples with previously unheard-of accuracy.

Researchers can learn a great deal about genetic links and diseases as well as create brand-new remedies for illnesses by examining these traits.
