Answer: Antigens on the blood determine a person's blood type. Antibodies in the blood attack foreign blood not compatible with the antigens on the blood. Still stuck?

Explanation:

Blood type is determined by the presence or absence of specific antigens on the surface of red blood cells.

The presence or absence of certain antigens on the surface of red blood cells is described by blood type, which is a classification system.

The presence or absence of two types of antigens, A and B, determines the four major blood types: A, B, AB, and O.

The presence or absence of specific antigens on the surface of red blood cells determines blood type.

To avoid a potentially fatal reaction during a blood transfusion, it is critical to match the recipient's blood type with that of the donor.

When a person receives blood that does not match their blood type, their immune system may recognise the foreign blood cells as invaders and mount an immune response.

Therefore, blood type matching is essential to ensure the safety and effectiveness of blood transfusions.

Answer:

because lenticels permit the exchange of gases between the environment and the internal tissue spaces of the organs

Fruits and stems have lenticels. These are the specialized cells which permit the exchange of gases between the atmosphere and the plant body.

A lenticel is a specialized tissue which is a porous tissue. It consist of cells with very large intercellular spaces in the periderm of the secondarily thickened organs in the plant body and the bark of the woody stems and roots of the dicotyledonous flowering plants.

Lenticels can be easily seen as they are visible on the surface of fruits, such as mango, apple, and avocado. Lenticels permit the exchange of gases between the external environment and the internal tissue spaces of the organs such as stems and some fruits of the plant body. These cells permit the entrance of oxygen gas into the plant and simultaneously the output of carbon dioxide and water vapor from it.

A parrot and dog are the two animals are able to generate internal heat to maintain their body temperature in a cold environment.

Polar and tundra biomes are examples of cold settings. They are the world's coldest climates. At the poles are polar zones. The Arctic is formed in the north by sea ice, and Antarctica, which is covered in ice, forms the Arctic in the south.

Arctic tundra, which surrounds the north pole and stretches south of the taiga's coniferous woods, is found in the northern hemisphere. One-fifth of the area on Earth is made up of the tundra. Of all the biomes, tundra is the coldest and driest.

The name tunturia, which means treeless plain, is derived from the Finnish word for tundra. It is  (soil that is permanently frozen) may exist on the ground, but the top layer melts over the summer.

Answer:

Temperate Zone Ecosystem

Explanation:

Yellowstone National Park has one of the largest temperate-zone ecosystems. Not to mention there is tons of diversity within the park from the wildlife, to the vegetation, and the lakes.

5 reasons why wolves make Yellowstone better:

1. Rebalanced elk & deer populations

2. Return of certain species: songbirds, beavers, eagles, & foxes

3. Vegetation species like aspen trees made a return

4. Enhanced tourism opportunities

5. They help to redistribute nutrients and provide food for other wildlife species

5 reasons why wolves make Yellowstone worse:

1. Decline of the elk herd that lives in the Northern range

2. Changed animal behaviors (mainly elk)

3. Attacking livestock & affecting ranchers

4. Reduced hunting opportunities

5. Pose a possible threat to tourists & pets

Elk are healthier because wolves prey on the sick and wounded elk since they are easy to attack. Wolves ruling out the sick elk help the herds by preventing any sicknesses/diseases. When elk aren't being hunted they spend most of their time feasting away which has negatively impacted vegetation and it can also hurt them (overeating). Now that wolves hunt them, they no longer overeat.

Wolves and bears are at the top of the food chain in Yellowstone. They prey on elk and bison as their main source of food.

1 and 2 are formed by underground reactions between acid in groundwater and limestone. So, the correct option is (A).

Groundwater is defined as the water which exists below the Earth's surface in the pores of rock and soil and in the fractures of rock formations. Available freshwater in the world is groundwater is about 30 percent. A unit of rock in the form of unconsolidated deposit is called an aquifer when it can produce useful quantities of water.

It is the underground water present in the saturated zones below the surface of the land. Groundwater does not form underground "rivers". But since it fills the pores and fractures in underground materials such as sand, gravel and other rock.

The upper layers of soil above the groundwater contain carbon and limestone. The water combined with the carbon becomes acidic which destroys the limestone resulting in the formation of sinkholes and caves.

Thus, 1 and 2 are formed by underground reactions between acid in groundwater and limestone. So, the correct option is (A).
