Answer:
A heterogeneous mixture of water, carbon dioxide, oxygen, glucose molecules
At a molecular level, looking at a tree involves observing atoms and molecules that combine to form more complex structures such as cells, tissues, and organs. These microscopic structures support the tree's growth, function, and ability to adapt to its environment. Thus, a tree represents various levels of biological organization.
Molecularly speaking, when you look at a tree you're witnessing an array of complex structures that form the basis for life. This includes atoms, the smallest and most fundamental units of matter that form molecules. Many biologically important molecules in the tree are macromolecules, large molecules formed by polymerization where smaller units called monomers combine. These molecules are significant components of the tree's cells which are the fundamental building units of life.
Additionally, what you're also seeing are elements of the tree's structure including tissues and organs that are formed by these cells. For instance, the tree's leaves contain specialized cells like guard cells which help regulate gas exchange. On a larger scale, these molecules and cells also contribute to the overall health, function, and resilience of the tree in its ecosystem.
Therefore, when you look at a tree, you're essentially witnessing numerous levels of biological organization. These range from the level of molecules and cells up through tissues and organs, to the entire tree or organism itself. This allows the tree to grow, function, and adapt to its environment.

Answer:
Option A, helps prevent rapid breakdown of the messenger RNA
Explanation:
The poly-A tail is a chain of adenine nucleotides which when get attached to the messenger RNA during RNA processing enhances the stability of the molecule and therefore prevents it from breaking down. This is required because after the transcription of gene in a eukaryotic cell, newly formed RNA molecule undergoes several modifications. It also helps is preventing the new RNA from enzymatic degradation in the cytoplasm and translation.
Hence, option A is correct
B. the death of macrophages
C. antigens trying to infect the area
D. blood cells losing their hemoglobin
Answer:
C: A solid metal ball in the middle of a pool of liquid.
Explanation:
Since the student is studying the earth, the core area is made up of a solid metal ball in the middle of a pool of a liquid.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.
I hope this helped. I am sorry if you get this wrong.
Answer:
B.) Oceanic crust is denser than continental crust.
Explanation:
I just did it and got it right :)
