Answer:
South American Grasslands
Explanation:
When Charles Darwin arrived in South America he noticed that many species including rabbits were missing from the South American Grasslands. Instead he found flightless, ground-dwelling birds called rheas in these grasslands. These animals were not like rabbits but instead shared many similarities to ostriches, and only lived in South America, where ostriches lived only in Africa.
How did Alexander Fleming contribute to Science?
Answer:
Discovered penicillin
Explanation:
Alexander Fleming accidentally discovered penicillin in 1928. He left dirty petri dishes in his laboratory. When he did clean them, he discovered a mold growth, and around this mold, no bacteria were present. There were bacteria in other regions, but none around the growth. He then knew that he discovered an antibiotic: penicillin.
He received the Nobel Prize in Physiology or Medicine in 1945 for his findings. Today, penicillin is used to fight bacterial infections such as pneumonia.
Which matter cycle is MOST highly dependent on processes carried out by soil bacteria?
Answer:
I guess nitrogen cycle since rhizobium plays an important role in nitrogen cycle and it lives on the root nodules of leguminous plants in the soil.
The nitrogen cycle is VERY dependent on the processes carried out by soil bacteria.
What do you mean by nitrogen cycle?The nitrogen cycle is a biogeochemical cycle in which nitrogen changes into several chemical forms as it circulates between atmospheric, terrestrial and marine ecosystems. Nitrogen transformation can occur through both biological and physical processes.
The nitrogen cycle is a repeated cycle of processes in which nitrogen passes through living and non-living things: the atmosphere, soil, water, plants, animals and bacteria.
The nitrogen cycle is important because nitrogen is an essential nutrient for life on Earth. Nitrogen is an important component of amino acids, the building blocks of proteins, and nucleic acids, the building blocks of genetic material.

Calculate how much DDT you would consume if you ate 3 kg of squid (calamari).
Answer:
66 000 mg or 66g
Explanation:
If a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.
What effect does DDT have on animals?DDT is commonly used in pest control, but it is eventually replaced by other chemicals due to its numerous environmental side effects, which include the thinning of eggshells in birds, accumulation in the fatty tissues, disruption of the endocrine system of animals, etc., and being highly toxic to animals and birds, etc.
Hence, if a person consumes 3 kg of squid, the amount of DDT consumed cannot be confirmed because the amount and concentration of DDT vary; for example, if the squid is caught in an area where DDT is widely used, the squid contains more DDT.

In what type of rock do paleontologists generally look for fossils?
Answer:
Sedimentary Rock.
Explanation:
Not every type of rock contains fossils so paleontologists focus their discovery on areas with the type of rock most likely to contain them like said sedimentary rock.
- hope you have a nice day :)
Answer: They usually look for Sedimentary rock.
Explanation:
Most fossils "hide out" in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils.

Both plant and animal cells have a cell membrane. Describe the structure and function of the cell membrane.Ambas células, animal y vegetal, tienen membrana celular. Describe la estructura y función de la membrana celular.
Answer:
Explanation:
Similar to a guard at the outside of a club, deciding who should be allowed in and who to keep out, the cell membrane is semi-permeable, regulating the movement of substances in and out of the cell with the help of protein channels.
The cell membrane is a double layer of lipids (fats) and proteins that surround a cell and separates the cytoplasm/ organelles from its surrounding environment.
The cell membrane is present in plant and animal cells. It is the outermost protective layer of a cell.
What is a cell membrane?All cells' interiors are protected from the outside world by a biological membrane called the cell membrane. It is also known as the plasma membrane.
The phospholipid bilayer, which creates a permanent barrier between two aqueous compartments, is the membrane's basic structural component. These compartments are the inside and exterior of the cell in the case of the plasma membrane.
Identification, communication, control of solute exchange across the membrane, metabolic activities, active transport, absorption, and isolation of the cytoplasm from the surrounding environment are the primary roles of the plasma membrane.

Explain why a pocket mouses color influencs it’s fitness. Remember that fitness is defined by an organisms ability to survive and produce offspring.
Answer:
The pocket mouse is generally found in rocky outcrops in the deserts of the southwestern United States and Mexico.
Though the fitness of an organisms helps them to survive and produce offspring but the color of pocket mouse influences its fitness because the color of mouse helps them to survive from the predators. The rock pocket mouse having light color fur blend with dark sand and blend with the sand which increases their chances of survival and the allele for dark fur will be passed on to their offspring.
Hence, color of pocket mouse or rock pocket mouse influences its fitness.

Why do carnivorous plants eat insects?
Answer:
Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Most plants absorb enough nitrogen from nitrates in the soil. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead. Carnivorous plants have developed unique ways to catch insects, such as fluid-filled PITCHERS and spring-loaded traps.

Why is it essential that threatened species compete for resources successfully?
Answer:
So that they survive and can reproduce creating more of that species.
An invasive species is an organism that’s not native to a particular ecosystem but ends up invading the region. The populations of invasive species can rise sharply, in part because the species may not have natural predators to control their populations.
The graph shows the population of an invasive tree species spreading through a region. This tree has an earlier reproduction and growing season than many of the native trees. Give three examples of how this tree could affect competition with the native species of plants and animals in the forest.
Answer:
The early reproduction and growing season indicates that these trees will sprout sooner than many native trees. Because all trees need space to grow, the invasive tree species can reduce available space for native species to grow.
As the trees grow, they could limit sunlight availability for other species of trees and plants in the area.
Some plant-eating animals may rely specifically on native tree species for food. If the invading tree species reduces the supply of the native tree species, competition among the animals may increase.
Explanation:
This is the exact answer from edmentum, so you might wanna change it a bit. :)
These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.
What is Invasive species?All trees require area to grow, thus invading tree species may make less room for native species to spread out. As the trees develop, they may reduce the amount of sunlight that is available to nearby tree and plant species.
Some animals that consume plants might only consume local tree species. Competition between the animals may worsen if the invasive tree species lowers the availability of the native tree species.
Animals or plants that are invasive are those from another part of the planet that don't belong in their new habitat. Ship ballast water, an unintentional release, and individuals are the most common ways that they are introduced to an area.
Therefore, These trees will likely germinate earlier than many native trees because of their early reproduction and growing season.

The Kaibab squirrel can only be found at the north rim of the canyon. Scientists believe they were separated by plateau erosion that separated the forests of the Grand Canyon, isolating the Kaibab population of squirrels.
Answer:
The completed question is
Two animals that can be found at the Grand Canyon include the Abert’s and Kaibab squirrels. The Abert’s squirrel is found at the south rim of the canyon and in a few surrounding states. The Kaibab squirrel, however, can only be found at the canyon’s north rim, mainly on the Kaibab Plateau. The Kaibab squirrel is not found anywhere else in the world. Scientists believe that the squirrels are actually closely related and have developed separately as a result of geographic isolation. It is possible that the squirrels were separated by plateau erosion that separated the forests and isolated the Kaibab population. Some scientists are studying if the squirrels are now two separate species or if the Kaibab squirrel is simply a subspecies of the Abert’s squirrel. Separate species are unable to reproduce with each other. Which evidence would be used to support the claim that the squirrels are two separate species?
a.The Abert’s squirrel is found at the south rim of the canyon, but the Kaibab squirrel is found at the north rim of the canyon.

HappyState lab review packet answers diffusion through a membrane -beaks of finches - making connections - relationships and bio diversity
Answer:
Diffusion can happen with or without a membrane. It always takes place down a concentration gradient, which means the substance will diffuse from an area of higher concentration to an area of lower concentration.
Biodiversity is critical to maintaining the balance of the ecosystem. Without a diverse collection of organisms, the species in the environment cannot thrive and are at a risk of extinction in extreme cases.

King penguins live on or near Antartica. The females lay one egg at a time with an incubation period of more than 50 days. The female and male parent take turns carrying the egg to keep it warm and protected while the other parent returns to the sea to feed. How is this reproductive strategy similar to other examples you have learned about? How is it different?
Answer:
Sharing of responsibility or division of labor.
Explanation:
This method of reproductive strategy is actually or typically different to most of the ones I am conversant with. For example, when most animals are going through incubation period, especially the birds, it is the only female that carries out this process, and it will leave the place of incubation when it needs to feed. In other group of animals like reptiles, the female will lay eggs in a dug pit or land, lay its eggs and cover it up with sand which will eventually incubate the eggs.
But in this aspect, the incubation involved the male and the female, which is totally different from what I knew before.
The reproductive strategy of Penguins living in Antarctica is different from other.
King penguins live on or near AntarcticaPenguins have different reproductive strategies than others as they share the responsibility of bringing their offspring.
The female and male Penguins take turns holding the egg to keep it warm and covered while the other parent returns to the sea to find food.
Female birds lay eggs in the nest and keep warm during the incubation period until the eggs hatch.
Reptile like turtles lays their eggs by digging a pit and covering it up with sand for incubating.
