The three conditions that encourage the presence of marine life in the ocean are proximity to land, water depth and.
Answer:
Exposure to sunlight.
Explanation:
Sunlight is important condition necessary for the presence of Marine life in ocean. This is because sunlight provide energy for ocean current and wind waves. When this energy is converted to heat, it a layer of warm water which is present at the ocean surface which support most Marine life. Sunlight produce light energy which is needed for Marine life like algae to photosynthesized in addition with carbondioxide and water in order to to produce necessary for survival for most Marine life.

Eric has made a terrarium, a closed container with plants in it, and he has put
enough water into it to satisfy the needs of the plants. Does Eric need to add
water to his terrarium again? Why or why not?
Answer:
Yes
Explanation:
The water will be used by the plants sooner or later so their basic metabolic needs can be achieved. Also, the plants will loose their water by transpiration, in order to produce their carbohydrates. Therefore the amount of water will not be enough and has to be replenished.

Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.

1. B. Use diffusion to
explain what happens when you drop a
sugar cube into a mug of hot tea.
2. A. What is osmosis?
2. B. Describe how water molecules
move through the cell membrane during
osmosis.
Answer:
Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.

1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.

Competition for light and resources with the oak tree
Answer:
Competition for light and resources with grasses
Explanation:
Mosses are small, flat brioftas that have no conductive vases, flowers, fruits and seeds. In a situation where a region has an intense density of trees as shown in the question above, mosses may be left with a limited amount of resources necessary for their survival, which will decrease their population. As a result, the moss will compete with other plant species.
In relation to the question above, the population of mosses would decline due to the competition for resources with grasses, this is because grasses have advantages in the absorption of resources, due to their biology.

Biodiversity determines the different types of species living in a given area. Hence it is incorrect
Bioremediation is basically a waste management system in which organisms are used to break down hazardous substances into less toxic substances. Hence, it is also incorrect
Hemodialysis is used to remove or filter out wastes and water from blood. Hence, it is also incorrect
Genetic engineering is used to produce organism with desired trait by altering their DNA and hence the associated Phenotype. Thus, it is the correct answer
Hence, option B is correct
Answer:
Genetic engineering
Explanation:
Genetic engineering is a technique in which DNA of desired gene is isolated from the body of an organism and inserted into the body of host cell. The host cell then develop organism or species with the characteristics of desired gene. The organism with genetic manipulation are called genetically modified organism (GMO).
Genetic engineering has many application such as human growth hormones, mass-produce insulin, follistim (for treating infertility), monoclonal antibodies, increasing productivity of animals and plants et-cetra.
Some animals are unable to breed or produces organism due to genetic diosrders or mutaions, with the help of genetic engineering a DNA with gene of interest can be inserted in the host or animal cell, which will treat or remove the natural barries and will make enable it for breeding.
Hence, the correct answer is Genetic engineering.
Compare variation adaptation of organisms in different ecosystems
Answer:
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Although scientists discussed adaptation prior to the 1800s, it was not until then that Charles Darwin and Alfred Russel Wallace developed the theory of natural selection.
Wallace believed that the evolution of organisms was connected in some way with adaptation of organisms to changing environmental conditions. In developing the theory of evolution by natural selection, Wallace and Darwin both went beyond simple adaptation by explaining how organisms adapt and evolve. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution.
Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions. An example of biological adaptation can be seen in the bodies of people living at high altitudes, such as Tibet. Tibetans thrive at altitudes where oxygen levels are up to 40 percent lower than at sea level. Breathing air that thin would cause most people to get sick, but Tibetans’ bodies have evolved changes in their body chemistry. Most people can survive at high altitudes for a short time because their bodies raise their levels of hemoglobin, a protein that transports oxygen in the blood. However, continuously high levels of hemoglobin are dangerous, so increased hemoglobin levels are not a good solution to high-altitude survival in the long term. Tibetans seemed to have evolved genetic mutations that allow them to use oxygen far more efficently without the need for extra hemoglobin.
Organisms can also exhibit behavioral adaptation. One example of behavioral adaptation is how emperor penguins in Antarctica crowd together to share their warmth in the middle of winter.
Scientists who studied adaptation prior to the development of evolutionary theory included Georges Louis Leclerc Comte de Buffon. He was a French mathematician who believed that organisms changed over time by adapting to the environments of their geographical locations. Another French thinker, Jean Baptiste Lamarck, proposed that animals could adapt, pass on their adaptations to their offspring, and therefore evolve. The example he gave stated the ancestors of giraffes might have adapted to a shortage of food from short trees by stretching their necks to reach higher branches. In Lamarck’s thinking, the offspring of a giraffe that stretched its neck would then inherit a slightly longer neck. Lamarck theorized that behaviors aquired in a giraffe's lifetime would affect its offspring. However, it was Darwin’s concept of natural selection, wherein favorable traits like a long neck in giraffes survived not because of aquired skills, but because only giraffes that had long enough necks to feed themselves survived long enough to reproduce. Natural selection, then, provides a more compelling mechanism for adaptation and evolution than Lamarck's theories.
Explanation:There you have it!! Hope its good enough for ya!!
Physical or behavioral characteristics that help an organism fit in with its surroundings are called adaptations. Random mutations result in heritable variation. New heritable features are initially caused by random mutations.
What is adaptation?The process by which organisms adapt to their environment in order to increase their chances of surviving in that environment is known as evolutionary adaptation, or simply adaptation.
Animals can defend themselves against predators and extreme weather by adapting.
Numerous birds may conceal themselves under long grass, while weeds, insects, and other creatures can alter their color to blend in. Predators find it challenging to locate them in search of food as a result.
Each biome's native plant and animal species have unique adaptations that enable them to endure the environment there.
Numerous species are endemic to particular biomes, which means they can only be found there. Some species can adapt to a greater range of climatic and geographic factors than others.
Thus, these are the variation adaptation of organisms in different ecosystems.
