Artery and veins are the blood vessels responsible to carry oxygenated and deoxygenated blood respectively. The innermost layer of these blood vessels is referred to as tunica interna.

What are blood vessels?

Blood vessels are responsible for circulating blood from heart to other body parts and vice-versa.

These carry oxygenated blood from heart to other cells and deoxygenated blood from cells to lungs and then to heart.

These are of two types, namely artery and vein.

The innermost layer of an artery or vein is referred to as the tunicainterna.

Thus, the correct answer is tunica interna.

A bird's wings are homologous to  a dog's front legs. Thus option C  is correct.

what is homologous structure ?

Homologous structures shows the same structure, but may have a different function or same function.

Homologous structures have a common ancestor, this structure is an organ or bone that's in common between different animals that demonstrates an anatomical structure indicating that the animals share a common ancestor.

This is in contrast to analogous structures where two unrelated animals have structures with similar forms or functions due to convergent evolution.

Patterns of __C_____ indicate how age at death influences population size.

-there is an aquatic biome where fish, whales, sharks, sea snakes, dolphin...etc have to live in water as their gills cannot breathe in oxygen air they need you can say oxygen water and they can filter the waste gasses.

- there is an desert biome you have animlas such as the Fennec fox, camels, lizards, armadillos, scorpions...etc they can live in the desert bc they can make their water stay in they're body's or even save water in they're bodys. some animals even have thick layer skin so that their moisture doesnt loss

- there is the forest biome where snakes, frogs, types of bugs, monkey, fox, birds, bats, even tigers....etc in a forest there is mostly everything you can find for animals of their needings such as rivers, rivers with fish in it, other animal preys, lots of greens for herbivores, shelter, huge tress for birds to live in, caves for bears or other animals to live in dirt for insects to dig in and make a home or even rabbits, alot of fresh air, the enviroment temperature can be cold or hot...etc

- same thing goes for tropical rain forests but tropical rain forests contain more moist and greens (tress, plants..etc) and in a tropical forest its never dry! in a tropical forest you can find animals similar to the regular forest except sloth, toucans, parrots, capybara, anacondas, howler monkeys..etc animals you can find in a regular forest.

- grasslands is where the whole area is coverd in grass, or wheat, or some plant plantation, here you can find horses, cows, sheep( in the more greener grasslands), ferrets, lions, cheetahs, giraffes, zebras, antelopes, you can find too. in grass lands you basically have animals who live with out shelter (or unless under a tree or cave sth) cuz basically animals in grass lands usually travel in pairs and sleep in pairs and eat in pairs cuz its much more safer. and you could find river streams or ponds.

i gave you four biome! and it took long to long to write XD

Final answer:

Biomes are distinct biological communities formed in response to a shared physical climate. They include aquatic, desert, forest, grassland, and tundra biomes, each with organisms that have specific adaptations for survival.

Explanation:

Biomes are distinct biological communities that have formed in response to a shared physical climate. They can be categorized into five major types: aquatic, desert, forest, grassland, and tundra.

• Aquatic Biomes: Both phytoplankton and larger plants have adaptations allowing them to live in water, such as streamlined shapes for reduced water resistance in animals, or floatation mechanisms in plants.
• Desert Biomes: Organisms in desert biomes, such as camels and cacti, have adaptations to handle extreme heat and scarcity of water. For instance, camels store fat in their humps and have specialized kidneys to reduce water loss. Cacti have deep root systems and store water in their stems.
• Forest Biomes: Animals like squirrels adapt to this environment by using trees for shelter and food. Plants have adaptations like broad leaves to capture sunlight.
• Grassland Biomes: Animals, such as bison, have adapted to handle wide temperature ranges, and some grassland plants have deep roots to survive fires and droughts.
• Tundra Biomes: Organisms, like polar bears, have adaptations to handle cold temperatures, such as thick fur. Plants in these regions tend to be short with adaptations to withstand freezing and thawing processes.

In each biome, organisms have developed physical and behavioral adaptations over time to survive within these distinct ecosystems.
