Charles Darwin postulated ancestral species over time adapted beak size changes in finch species to acquire different food sources. Hence option b is correct.
What is darwins theory for natural selection?During his voyage, Charles darwin observed unique beak sizes among the finches species on the Galapagos islands.
Due to competition for available food sources island finches change their beak size and shape to acquire food sources, these changes are selected by natural selection.
Natural selection theory depends on how the species changes in their body over evolution.
Therefore, the finch population has a unique beak shape and size on Galapagos island, so option b is correct.

“Why is there so much peat in the peat/perfrost system? Minimum of 5 sentences
PLEASE HELP
There is so much peat in the peat /perfrost system as a result of the low oxygen concentration in the environment which leads to incomplete decomposition occurring.
What is a Peat?This substance has a soft and dark brown property and is formed from partially decaying organic matter and dead substances present in a long period of time.This could take a certain period of years and are also rich in carbon content.
Perma frost is referred to an area which is located on land or under the ocean in areas where there is a low concentration of oxygen as result of certain factors and properties.
Since we are aware that peat is formed partially decaying organic matter under low oxygen concentration, then it is therefore the reason why there is so much peat in the peat/perfrost system and is therefore the correct choice.

The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary between plants and animals depending on its general function. True or false?.
Answer:
I believe its True
The organelle is common to many types of cells and is the primary site for storage of materials such as water, proteins, lipids, and cellular waste. The size of the organelle can vary, and it is a vacuole. This is the true explanation.
What are the different functions of the cell organelles?The cell organelles are different in different organisms, such as plants, animals, yeast, etc., because the cell organelles and their functions vary too. The plant cell has a large vacuole, which contains water, proteins, lipids, cellular waste, etc., it has mitochondria, a nucleus, etc., and the function of the vacuole is different from that of the animal cell vacuole. The vacuole of the plant cell is larger than that of the animal cell because the plant cell vacuole maintains the water pressure, but the animal cell does not do this.

Why do scientists think gases such as CO2 trap heat in the atmosphere?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can trap heat. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth.
Carbon dioxide is Earth's most important greenhouse gas that works for absorbing and radiating heat. Greenhouse gases absorb heat radiating from the Earth's surface and even circulate it in all directions including back toward Earth's surface.
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere's carbon dioxide content by 50% in less than 200 years.

The responsibility to preserve and protect the environment is known as ecological responsibility. The majority of the time, ecological responsibility is related to businesses making sure that their operations always abide by environmental laws and regulations.
Explain about vegetarian diet is more Ecologically responsible?People can drastically minimize their consumption of land, water, and oil resources as well as the amount of pollution they might otherwise generate by selecting a vegetarian diet rather than one high in animal products.But when the study's 153 vegans, vegetarians, and omnivores were all included in, it became clear that eating meat was, on average, worse for the environment. When we think about food crops, there are other broad issues to keep in mind that could have a greater negative influence on the ecosystem.According to a thorough peer assessment of studies on vegetarianism, a non-meat diet will probably result in a person emitting less carbon dioxide than they would with a meat-based diet—roughly 1,200 pounds less carbon dioxide. That translates to a mere 4.3% reduction in emissions for the average person living in industrialized nations.

True, the archaea and eukarya are more closely related to each other than they are to the bacteria
The archaea, eukarya and bacteria are described by the Woese's tree of life.
What is Woese's tree of life?
This is a unique research program developed by Carl Woese, it is based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea.
The tree indicates that the common ancestor for eukarya and archaea is more recent than the common ancestor for all three domains.

In addition, since we lack peptidoglycan in our bodies, an enzyme that kills bacteria won't have the same impact on human cells. This is excellent for human health since it can help stop bacterial infections. Because it will presumably destroy microorganisms, we detect it in human secretions that come into contact with the environment, such as tears and saliva.

For the gaseous exchange to work efficiently, there must be a difference in concentration between the gases in blood and in alveolus. Give two ways in which these differences are maintained.
The differences between the concentration gradients of gases in blood and in alveolus is maintained by two processes called inhalation and exhalation.
The process of inhaling oxygen rich air is called inhalation and the process of expelling out carbon dioxide rich air out from the body is called exhalation. Inspired air is rich in oxygen which is stored in the lungs or alveoli temporarily and the carbon dioxide from the blood is expelled out through the lungs through a process called gaseous exchange.
During respiration, diffusion accounts for the majority of gas exchange. A concentration gradient drives movement through the mechanism of diffusion. In the lungs, blood that has a high carbon dioxide content and a low oxygen content exchanges gases with the air. Compared to the blood, which is depleted of oxygen, the air in the lungs contains more oxygen and less carbon dioxide. During respiration, gas exchange is made possible by this concentration gradient.
