Answer:
Permafrost, amber and tar
Explanation:
Fossils are the remains of prehistoric plants or animals embedded and preserved in rocks. They are preserved by three main methods: unaltered soft or hard parts, altered hard parts, and trace fossil.
Soft-tissue original remains are very rare except as captured in amber, trapped in tar, dried out or frozen in permafrost.
Amber is ancient tree sap that can trap flowers, worms, insects as well as small amphibians and mammals and preserve them whole.
Permafrost is an area of land that is permanently frozen below the surface. It is common in Siberia (part of Russia) and in Alaska. Many different kinds of frozen extinct as well extant animals have been found in Siberian permafrost, including woolly mammoths, horses and bison, and lions.
Tar or asphalt is a liquid found naturally in small pits in swamps. These pits are formed from crude oil seeping through the ground. The lighter elements of crude oil evaporate leaving thick sticky asphalt. Animals that fall into these pits hardly escape and their bodies are preserved within. Fossils of animals such as wolves, short-faced bears, American lions, ground sloth and saber-toothed cat have been found preserved intact in tar.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.
Answer:
Leaves are always the color they turn in the fall
Explanation:
The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.
I hope this helps and good luck on that two-pager!
Answer:
During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy
Answer:
the other 60% of energy is stored away for further use in the cell
Explanation:
i hope im right
In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.
How does ATP form from glucose?Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.
Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.
To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain. The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .
Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.

What are the main differences between asexual reproduction and sexual reproduction?
1. Asexual reproduction requires two parents and produces non-identical offspring, while sexual reproduction requires only one parent and produces identical offspring.
2. Asexual reproduction requires two parents and produces identical offspring, while sexual reproduction requires only one parent and produces non-identical offspring.
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
4. Asexual reproduction requires only one parent and produces non-identical offspring, while sexual reproduction requires two parents and produces identical offspring.
Answer:
3. Asexual reproduction requires only one parent and produces identical offspring, while sexual reproduction requires two parents and produces non-identical offspring.
Explanation:
Asexual - one parent only. Offsprings looks identical
You could see that in plants and flowers where each offspring looks the same
Sexual - two parents. Offsprings do not look identical
Ex : Animals and humans. We need a male and a female/ egg + sperm. The offsprings produced are non identical as genes from both parents are included
Answer:
3
Explanation:
asexual requires only one parent (think Jurrasic park lost worlds with the girl and the velociraptor they both are products of asexual reproduction)
sexual requires two parents to make the baby
What information would best further the understanding of the relationship between the number of amino acid codons and their frequency in proteins?
Answer:
Explanation:
The information about the structure of a protein is key to understand its function and why certain codons are distributed the way they are. We know that proteins have several structures:
The primary structure, which is defined by the sequence of nucleotides in RNA.
The secondary structure, the regular arrangement of amino acids within located regions of the polypeptide. The most common structures are α-helices and β-sheets.
The tertiary structure, the folding of the polypeptide chain as a result of the interactions between the lateral chains of the amino acids that are located in different regions of the primary sequence.
The quaternary structure, which consists of the interactions between different polypeptide chains in proteins formed by more than one polypeptide, as is the case with hemoglobin.
We know that structure and function are strongly related to one another, and a crucial determinant for the tertiary structure is the location of the hydrophobic amino acids inside the protein and the hydrophilic amino acids on the surface, where they interact with water. The interior of the folded proteins are constituted mostly of hydrophobic amino acids organized in α-helices and β-sheets, these secondary structures are located within the hydrophobic center of the protein. The bow regions that connect the elements of the secondary structure are located on the surface of the folded proteins, where the polar components form hydrogen bonds with water or with the lateral chains of the hydrophilic amino acids.

Why can’t a purine hydrogen bond with another purine within the sugar phosphate backbone of DNA? State your reason with all the details that are required to answer the question for full credit.
Answer:
due to the structural-binding properties of the nitrogen bases
Explanation:
Adenine and guanine are purines (two-carbon nitrogen ring bases) that pair with thymine and cytosine pyrimidine nitrogen bases (one-carbon nitrogen ring bases), respectively. These specific base-pair rules are due to their hydrogen bonds (i.e., van der Waals forces), which stabilize the structure of the DNA helix. Cytosine and guanine have three sites to form hydrogen bonds to each other, while adenine and thymine have only two sites. The specific interactions between purines and pyrimidines are critical for proper bonding and attachment to the sugar-phosphate DNA backbone (i.e., for the formation of the DNA double-helical arrangement).

Answer:
C. mitosis
Explanation:
Mitosis is one of the two types of cell divisions in which a single cell divides into two genetically identical daughter cells. Mitosis is used for growth and repair of tissues in living organisms.
Mitosis is also the process by which cells multiply/duplicate themselves. Hence, the process of a cell increasing its size, doubling its genetic contents, dividing into two independent cell, and repeating the process over and over again is called MITOSIS.
