Biomes are areas with distinct climates and distinct ecosystems, characterized by certain plants and animals. The biological diversity of a biome is determined by the number and variety of organisms found there.
The following sets of biomes are placed in order from most to least biologically diverse:
Tropical Rainforest - This biome is characterized by a warm and wet climate, and is home to a wide variety of plants and animals. The dense forests and high humidity make this biome the most biologically diverse of the sets listed.
Temperate Seasonal Forest - These forests typically have four distinct seasons and are home to a wide variety of animals and plants, though not as varied as the tropical rainforest.
Woodland/Shrubland - This biome is characterized by shrubby vegetation and temperate climates. While there is a wide variety of plants and animals found in this biome, it is not as biologically diverse as the other biomes listed.
Subtropical Desert - This biome is characterized by hot, dry climates and sparse vegetation. There are a few species of plants and animals that can survive in this environment, but overall there is less biological diversity than in the other biomes.
Tundra - This biome is characterized by cold climates and low levels of vegetation. Few species of plants and animals can survive in this environment, and so it is the least biologically diverse of the sets listed.

PLEASE TYPE THE RESPONSE Charles Darwin proposed that evolution by natural selection was the basis for the differences that he saw in similar organisms as he traveled and collected specimens in South America and on the Galapagos Islands. A) Explain the theory of evolution by natural selection as presented by Darwin. (6 Marks) B) Each of the following relates to an aspect of evolution by natural selection. Explain TWO of the following. (8 Marks) (i) Convergent evolution and the similarities among species in a particular biome. (ii) Natural selection and the formation of insecticide-resistant insects or antibiotic-resistant bacteria. (iii) Speciation and isolation. (iv) Natural selection and heterozygotes advantage.
According to the theory of evolution by natural selection as presented by Darwin, organisms breed more young than they can withstand in their surroundings.
Charles Darwin's theory of evolution is known as natural selection. Animals with heritable traits that favor survival and reproduction will often generate more offspring than their contemporaries given the shortage of resources in nature, increasing the population frequency of such traits across successive generations. Those with more physical capacity to endure, develop into adults, and reproduce.
Darwin started to question if South American species had made it to the Galapagos and had since transformed as a result of climatic adaptation. This notion—that species could alter over time—ultimately inspired Darwin to develop his theory of evolution through natural selection.

What makes a body of water a lake?
If a body of water satisfies the following requirements, it is typically referred to be a lake. There is a body of still water there that is encircled by land. It does not belong to or connect to an ocean or sea, nor is it a river or other body of water that does.
Its features are not reliant on those of another body of water since it has its own ecology. It is a sizable body of water, often larger than a pond, and ranges in size from little ponds to enormous lakes like Lake Superior and Lake Victoria.
Although it can be constructed by human activity such as damming a river or glacial activity, this reservoir was not made by humans.
It's worth noting that the definition of a lake can vary depending on the region, and some bodies of water that are called lakes in one area may not be considered lakes in another area.

Why must cells have an upper and lower limit to their size?
Cells are the basic building blocks of life and, as such, are essential for the functioning of all living organisms. For that reason, it is important for cells to have an upper and lower limit to their size. These limits serve vital roles in cell structure, function, and metabolism.
The upper limit to cell size is important because too large of a cell can cause problems with cellular communication and the distribution of nutrients throughout the cell. In general, larger cells are more difficult to maintain, as they require more energy and resources to sustain their structure. If a cell exceeds its upper limit, it becomes too big to be supported by the metabolic resources available to it and eventually dies.
The lower limit is also important for cellular function. Cells that are too small have difficulty forming necessary structures and have a harder time performing certain metabolic processes. This is because small cells are limited in the number of organelles they can contain and the number of molecules they can process. Small cells are also less efficient in their use of energy and resources, making it difficult for them to survive in certain environments.

What happens to the amount of nutrients needed as a cell increases in volume?
As the volume of a cell increases, so does its need for nutrients. This is because larger cells require more energy, as well as more materials, to sustain their increased size. In order to keep up with the increased demand for energy, larger cells must absorb more nutrients, including proteins, carbohydrates, lipids, and other essential molecules.
The two primary methods by which cells acquire nutrients are diffusion and active transport. Diffusion is a passive process that occurs when molecules move from an area of higher concentration to an area of lower concentration. This process occurs in cells and can provide the necessary nutrients for growth and maintenance. However, diffusion becomes increasingly inefficient as the cell size increases due to the increased distance the molecules must travel.
Active transport, on the other hand, is an energy-driven process in which molecules are actively transported into the cell from an area of lower concentration to an area of higher concentration. This process allows for the rapid transport of larger molecules and the more efficient uptake of nutrients. As the volume of the cell increases, more active transport is needed to provide the necessary nutrients. This can be seen in the process of endocytosis, where the cell engulfs nutrients from the environment and transports them into the cell.

"The World on Turtle's Back," is a myth created by the Iroquois to explain the origin of the earth and living things. In this myth, we can see:
There was a realm above the heavens that was created even before the earth was created.
This realm was inhabited by magical beings who did not die, grow old, or get sick. They were called the people of heaven.
There was a tree in the center of that realm that was holy.
The tree lit up the entire kingdom, since the sun did not exist.
One day, one of the women of the heavenly realm discovered that she was pregnant with twins. She is very happy and tells her husband, but he is furious with the news, to the point of pulling the sacred tree from the ground. This causes a hole and he throws his pregnant wife into that hole.
The man is terrified, not because he threw his wife to an unknown end, but because he destroyed the sacred tree and is afraid of being punished.
Despite the fall, the woman survives and gives birth to the twins who will create all the elements of planet earth.
