The type of rock from which its made is the characteristics of the lower mantle causes it to contain more liquid than sections in the upper mantle.
What do you mean by mantle?A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body.
The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume. As Earth began to take shape about 4.5 billion years ago, iron and nickel quickly separated from other rocks and minerals to form the core of the new planet.
The mantle is made up of a semi-molten rock called magma. The mantle can be split into two different sections which consist of the lower mantle, which is made from a more solid rock.

Prior to the formation of a land bridge about 3 MYA that allowed placental mammals to invade, marsupials were diverse and abundant on what other continent besides Australia
Prior to the formation of a land bridge about 3 MYA, marsupials were diverse and abundant in SOUTH AMERICA. The western half of Gondwana separated from the eastern half million years ago.
Gondwana was a super landmass containing all continents that began to break up during the Jurassic.
The western half of Gondwana (i.e., Africa and South America) separated from the eastern half (i.e., India, Australia, and Antarctica) million years ago.
This separation led to the divergence of many taxonomic groups, including Australian marsupials and South American marsupials.
Some South American marsupials include, among others, Andean caenolestid, Chacoan gracile opossum, long-nosed caenolestid etc.

If you start with 60 chromosomes and end with 60 chromosomes
If you start with 60 and end with 60, then no change has occurred. Mitosis is part of cell replication, so if we end with the same number as we started with, then no form of mitosis has occurred.
I hope this helps! :)
If we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.
What is Mitosis?Chromosomes that have been duplicated are splitting into two new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.
Mitosis is a process used to create more cells that share the same genetic makeup as the parent cell. It is essential to the expansion and development of human bodies as well as for the embryonic development of living things. Mitosis generates new cells and replaces injured, destroyed, or ageing ones.
Thus, if we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.

Suppose that there is a mutation in a suppose that there is a mutation in a single-celled organism where the Krebs cycle (TCA/Citric Acid Cycle) doesn't happen. What would be the consequences for that organism? How would their metabolism be similar to ours? How would it be different?
In this case, the organism would not be able to produce ATP in aerobic conditions. The Krebs cycle is fundamental in humans.
Cellular respiration consists of a series of metabolic reactions by which aerobic cells can produce ATP (the energy coin of the cell) by using the energy stored in foods and oxygen.
Cellular respiration has three types of sequential reactions: glycolysis, the Krebs cycle and oxidative phosphorylation.
During the Krebs cycle, the energy from foods (e.g., carbohydrates) is released through the oxidation of acetyl-CoA.

Answer:
1) carbon dioxide, water, and sunlight.
2) glucose and Oxygen, and humans got benefited by consuming (breathing oxygen) that are produced by plants while photosynthesis.
3)During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Which of the following would increase species biodiversity in Florida?
A.
Placing no limits on alligator hunting in lakes
B.
Legalized hunting for monkeys around the St. John’s River
C.
Protecting black bears in state or national forests
D.
Clearing land for a new entertainment theme park
Answer:
C
Explanation:
Biodiversity measures the variety of organisms in an ecosystem. Allowing hunters to hunt alligators depletes the alligator population which decreases biodiversity. Legalizing monkey hunting depletes the population which decreases bio diversity. Deforestization rids animals of their habitats which massively decreases biodiversity due to the plants, trees, and animals destroyed in the process. That and the fact that there will be less sites for nesting and homes for the animals which will decrease biodiversity even more over time. It's all connected.
Protecting a species conserves the population and ensures the safety of the animal especially from human interference. This allows the animal (specifically the black bear) to survive in its habitat unharmed and allows it to play its role in the ecosystem and contribute to biodiversity.

Which two organisms are most closely related, based on the tree above?
ray-finned fishes and sharks
rodents and primates
dinosaurs and crocodiles
dinosaurs and birds
Answer:
dinosaurs and birds
The two organisms that are most closely related are dinosaurs and birds.
Why are organisms related?Organisms are related because they share a common ancestry, meaning they have evolved from a common ancestor through genetic and evolutionary changes over time.
Based on the tree above, the two organisms that are most closely related are dinosaurs and birds. This is because birds are descended from a group of small, feathered dinosaurs that lived during the late Jurassic period, and are therefore considered to be a type of dinosaur.
The branch point where birds diverge from other dinosaurs is relatively recent on the tree, indicating that they share a more recent common ancestor than other organisms on the tree. In contrast, ray-finned fishes and sharks, rodents and primates, and dinosaurs and crocodiles diverged from each other at earlier points in evolutionary history, indicating that they are less closely related to each other than dinosaurs and birds.
