blood type

not compatible with the antigens on the blood.
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.
What is blood type?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.

Evolution explains how variations can lead to changes in a species
Answer: Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. as we evolve our genetic genes change because the gametes come from 2 parents and has half the DNA (23) and thousands of years passes and if you will compare people in ancient times to now we are completely different.

Incomplete dominance is where neither allele is completely dominant
red cow = RR
white cow = rr
what percentage of the offspring will be red?
none would be red as all of the offspring is Rr which is heterozygous as they are both different alleles and R is not dominant which will not be red. Rr means that both red and white blend so they are all tan

Why does Earth’s surface change? How does Earth’s surface change?
Your paragraph should be a minimum of 5 complete sentences. Your answer to each question should include both an explanation and a few examples.
Question: "Why does Earth’s surface change? How does Earth’s surface change?"
Answer: "Earth is a system of frequent interaction between the surface conditions, interior, and external events. Many of Mother Nature's lets say 'Natural Disasters' is one of the many things that help to mold and shape our planet. Take, for example, volcanos into consideration: when the eruption begins within a volcano, it pushes up new material from underground, helping to create new land forms (this was how many of Hawaiian's islands were created.)
Shifting of tectonic plates within the Earth's crust and upper mantle is another reason. The plates are constantly interacting, and lets say, 'grinding' together, as well as some colliding and breaking apart. Any of these reactions to the shifting of the tectonic plates can build any of our landforms and landscapes (including mountain ranges, oceans, valleys, etc.)
Also, another case of nature, erosion of the surface from water, wind, sand, chemicals, and living land creatures can develop and mold the surface of Earth as well. Countless numbers of forces are frequently breaking down and departing the surface, moving and spreading the materials of the surface to other sides of the Earth, later on perhaps building new formations."

[FW.02]The pictures below show four Earth features.
Which of these features are formed by underground reactions between acid in groundwater and limestone?
A) 1 and 2
B) 2 and 3
C) 3 and 4
D) 1 and 4
Answer:
i think 3 and 4
Explanation:
and the reason i think this
is #1 is not a reaction
neither is #2 so yea
1 and 2 are formed by underground reactions between acid in groundwater and limestone. So, the correct option is (A).
What is Groundwater?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).

How did the removal of the wolf affect the ecosystem in Yellowstone?

List 5 reasons the wolf makes Yellowstone better.....
List 5 reasons the wolf makes Yellowstone worse.....
Why are elk healthier if the top predator; the wolf, is healthy and hunting them?
Who is at the top of the food chain in Yellowstone.
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.

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