Explanation:

if its correct please let me know

A narrowing of the valve between the lung arteries and the lower right heart chamber (right ventricle) is known as pulmonary valve stenosis (pulmonary arteries).

The valve flaps (cusps) of a constricted heart valve may thicken or stiffen, as a result, the valve's blood flow is decreased.

When that valve narrows, blood cannot flow correctly and aortic stenosis develops, mild to severe cases of the illness are possible.

The left ventricle of your heart has to work harder over time to force blood past the stenotic aortic valve.

Therefore, an abnormal narrowing of the right atrium and right ventricle is due to pulmonary valve stenosis.

Explanation:

Answer: c & d

Explanation:

C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis. A prokaryotic cell consists of a single membrane and therefore, all the reactions occur within the cytoplasm which can be free-living or parasites.

Eukaryotic cells are defined as having a nucleus enclosed within a nuclear membrane and form large and complex organelles. Protozoa, fungi, plants and animals all contain eukaryotic cells which are classified under the kingdom Eukaryota.

Thus, C and D provide a comparison of structures that encode genetic information for the cells. So, the correct option is C.

Explanation:

Given what we know about the effects of air currents on mountain ranges we can confirm that the correct option is option B, moist and rainy on one side while being dier on the other.

Mountains are described as having two sides in regards to their relationship with the air currents. The side of the mountain on which the wind rises is known as the windward side, whilst the side on which air descends is known as the leeward side. The windward side is typically in contact with warmer, moist air from the ocean and other bodies of water.

When coming in contact with the mountain, the air is forced to rise and begins to cool, which often leads to rain or snow. The leeward side of the mountain receives the air that has now already lost the majority of its moisture with its pass through the windward side of the mountain. This air also tends to become warmer as it descends, which explains the dry nature of the leeward side of mountains.

Answer:moist and rainy; drier

Explanation:

The correct answer is that chemicals added to the liquid can contaminate groundwater.

Fracking is a method of drilling fossil energy resources, which requires a lot of water and consumes local water resources. It is pumped with high pressure water, sand and chemicals, causing high pressure to block the porous rock and release gas.  

The water spill itself destroys nature from the drilling site, and may even cause earthquakes, especially due to the pumping of abundant wastewater into porous rock types such as limestone. For example, Oklahoma appears to have become a special earthquake risk area. The biggest impact of water distortion is on groundwater. In Wyoming, USA, the same chemicals found in groundwater have been found in groundwater, and some of them are toxic or carcinogenic.

Answer:

Derived trait

Explanation:

An ancestral (or primitive) trait/character is a feature inherited from the common ancestor of the species/group of interest, while derived traits are those that were absent in the last common ancestor of the group of interest. For example, considering mammals as the target group, the presence of hair is a shared derived trait relative to other vertebrates, i.e., amphibians, reptiles, and birds. However, this trait (hair) is ancestral for humans since the genetically closest species to humans (e.g., chimpanzees) also have hair.
