Answer:
Major histocompatibility complex (MHC) antigens
Explanation:
The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.
A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the transplanted organ.
Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

Which gas is most effective in absorbing incoming harmful ultraviolet radiation in the earth's stratosphere before that radiation reaches earth's surface?
Answer:
Ozone (O₃) gas
Explanation:
In the Earth's stratosphere, oxygen gas (O₂) is combined with atomic oxygen (O) to form ozone gas (O₃). This is very important because ozone protects the life on Earth from ultraviolet (UV) radiation from the Sun. UV radiation is high-energy radiation, and it is very dangerous for living organisms. Ozone molecule (O₃) absorbs UV radiation and it breaks down by forming O₂ and atomic oxygen (O) again. In this way, it protects the Earth from nocive radiation.
What are 2 examples Natural selection?
Answer:

Answer:
Due to suitable environment of the equator.
Explanation:
Latitude is abiotic factor that has a great impact on the occurrence of fish species as we can see in the graph, the fish species increases as we go towards equator whereas decreases when we go away from the equator. This is because the climatic condition and temperature of water at the equator is suitable and warm so this suitable environment attracts more species to lives there.
what provides new variation
Answer:
Mutation
Explanation:
The main cause of variation within a population is usually through genetic mutation.
Mutation is the alteration of the genetic sequence within an organism. It often lead to formation of new genetic patterns and codes.
Most times, environmental influences are paramount to causing genetic mutation within a population.
Other times, it might be due to competition and some other internal factors.
Mutation can be transferred from parents to offspring in most cases.

C. mountain lion-consumer; bark beetle-herbivore
D. grasshopper-carnivore; grass-autotroph
Please helpppp meee!!!!its a final
Answer:
C. mountain lion-consumer; bark beetle-herbivore
Explanation:
Food webs contain a series of inter-connected food chains. In a food web, organisms in different trophic levels feed on one another to obtain energy. Based on the diagram attached to this question, the roles of different organism is as follows:
- MOUNTAIN LION: This is a consumer i.e organism that feeds on other animals. This is the case as seen in the diagram that mountain lions are feeding on rabbits and Hawks.
- BARK-BEETLE: This is an herbivore because it feeds directly on the plants as seen in the attached image.
Imagine you are a systematist who has discovered an unfamiliar
animal. Which of the following observations about the animal will best
help you find its taxonomic classification?
The animal has an unpleasant temperament.
The animal has sharp, pointed teeth.
The animal was found near a herd of deer.
The animal bit you.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quick check
The observation about the animal that will be helpful in finding its taxonomic classification is B. The animal has sharp, pointed teeth.
Taxonomy refers to the science of the classification of organisms into groups. The classification is based on the characteristics that the organisms have.
Therefore, in a situation whereby the person is unfamiliar with an animal, the shape of the teeth of the animal can be used for its classification.
