Answer:

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other. The same is true for maple

Maritime air masses form over water and are humid.

Answer:Maritime air masses form over water and are humid. Continental air masses form over land and are dry. Therefore, an air mass that develops over northern Canada is called a continental polar air mass and is cold and dry. One that forms over the Indian Ocean is called a maritime tropical air mass and is warm and humid.

The correct answer B

When the body gets the glucose, the glucose in the blood increase then the hormone insulin is released so that the glucose from the blood can be transferred from blood into the cells of the body.

The release of hormone insulin is a positive feedback.

Once the glucose is transferred into the cells of the body then the negative feedback starts acting that stops the secretion of insulin from the pancreas.

What will happen next is that negative feedback would cause his pancreas to stop secreting insulin.

The maintenance of relatively constant internal body processes depends largely on negative feedback.

Negative feedback mechanisms ensure that setpoints are returned.

Hence, whatever causes setpoints to be breached is reversed or removed totally.

In this case, the continuous secretion of insulin will further lower the blood sugar level and causes the setpoint to be breached further. Thus, the actuator (insulin) has to be removed.

Answer:

We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.

Answer:

Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. Also, as lichens die, they provide some organic matter that also contributes to soil. Mosses can then colonize the thin soil; as mosses die, the soil thickens more allowing other hardy species to colonize

fertilization results in the formation of zygote.

Answer:

zygote

Explanation:

Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.

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.

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.

The correct pairing of human activity with the greenhouse gas it increases is: Deforestation and methane.

Deforestation refers to the deliberate or widespread removal of trees and vegetation from forests or woodland areas, leading to the conversion of forested land into non-forest uses. It involves the permanent destruction or clearance of forests, typically for purposes such as agriculture, logging, urbanization, or infrastructure development.

Deforestation has significant environmental, social, and economic implications. It contributes to habitat loss, biodiversity decline, soil erosion, and climate change. Forests play a crucial role in carbon sequestration, regulating the water cycle, and providing habitats for countless species.

Deforestation disrupts these ecological processes and can lead to the loss of invaluable ecosystem services. Efforts to combat deforestation involve sustainable land management, reforestation initiatives, and the promotion of responsible forestry practices.
