why don't all organisms become fossils when they die?
Answers
Answer:
Oxygen...
Explanation:
Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
Final answer:
Organisms do not always become fossils due to the specific and uncommon conditions required for fossilization, such as rapid burial in sediments or extraordinary preservation environments. The fossil record is thus incomplete, capturing only a fraction of past life forms under certain conditions.
Explanation:
Not all organisms become fossils when they die because the conditions required for fossilization are quite specific and rarely occur. Remains must be rapidly covered by sediments or preserved in unique circumstances such as being frozen in glaciers or trapped in tree resin. The environment plays a crucial role in preserving fossils, with physical conditions like temperature and water depth, and chemical conditions such as pH and oxygen levels greatly influencing this process. Organisms that do not get preserved in such a way eventually decompose fully.
Fossils help paleontologists understand Earth's history, evolution, and paleoenvironments. They also indicate that most species that have lived on our planet are now extinct. Fossils are not only a window into the past, but they are also a finite non-renewable resource, as is the case with fossil fuels derived from ancient organisms that decomposed under specific anaerobic conditions over millions of years.
While most remains eventually deteriorate, under favorable conditions such as volcanic ash, limestone, and mineralized groundwater, fossilization can occur, although it remains a rare event. This results in an incomplete fossil record, as the conditions for preservation don't happen frequently enough to capture all past life forms.

Explanation:
Answer:
Coding for the production of all cells protein
Explanation:
Chromosomes are long sequences of DNA that contain several genes and other sequences of nucleotides. In eukaryotic organisms, chromosomes are linear structures of highly stranded double-stranded DNA, normally found in the nucleus of cells, and may also be associated with proteins and RNA. In prokaryotic organisms, they have a circular or linear shape, not being present in the nucleus or associated with proteins.
In addition, chromosomes are the molecules responsible for controlling cellular processes. They do this by coding the production of all proteins in a cell.

Distinguish between mudflows and earth flows
Answers
Mudflows are rapid movements of water-saturated soil, notable for their high water content and perceptible speed, often found in arid regions. Earth flows are slower, lack defined channels, are common in humid areas, and contain less water. Debris flows involve larger materials and occur under different conditions, such as steeper slopes and greater water presence.
Differences Between Mudflows and Earth Flows
When comparing mudflows to earth flows, several key distinctions can be noted. First, mudflows are rapid downslope movements of water-saturated soil and regolith, which are easily perceptible due to their higher water content. They are more prevalent in arid regions with sparse vegetation and can occur after heavy rainfall or during volcanic eruptions. In contrast, earth flows are much slower and can sometimes be almost imperceptible. They are not confined to channels like mudflows and are more commonly found in humid areas. Additionally, earth flows tend to have lower water content compared to mudflows.
Mudflows consist mostly of sand-sized or smaller particles and can take on the form of lahars during volcanic activity, while earth flows involve finer materials. Debris flows, which are closely related to mudflows, involve larger clasts and require steeper slopes and more water to occur, often resulting in the collapse of bank material into a stream, leading to a sudden rush of water and debris.

Three generations of a family afflicted with hemophilia are illustrated in the pedigree chart. Family members used the pedigree chart and the laws of genetics to predict the occurrence of the disease. From the information in the chart, one can determine that hemophilia is
A) sex-linked and occurs more in males than females.
B) autosomal and occurs equally in males and females.
C) sex-linked and no pattern of inheritance can be predicted.
D) autosomal and occurs more frequently in males than females.
Answers
Answer:
The answer is A. Sex-linked traits are more often expressed in males because they are typically carried by the X chromosome and they are also typically recessive. Males only inherit one X chromosome, so if the one they inherit is linked to the disease, they will express it no matter what. Females, on the other hand, can be carriers if they inherit one X chromosome with the disease. This is because their other X chromosome can be normal, which would dominate the expression of the disease on their other X chromosome.

When wind moves particles of sediment in a way that makes them bounce or leap, this movement is known as
Answers
When wind moves particles of sediment in a way that makes them bounce or leap, this movement is known as saltation.
Saltation is a type of sediment transport that occurs when wind blows over a surface that is covered in loose particles. The wind blows the particles along the surface, but they are too heavy to be carried in suspension. Instead, they bounce or leap along the surface, sometimes reaching heights of several meters.
Saltation is an important process in the formation of sand dunes. The wind blows the sand particles along the surface of the dune, and the saltating particles knock other particles out of place, which helps to build up the dune. Saltation can also be a destructive process. The saltating particles can erode the surface of the ground, and they can also damage crops and other vegetation.

Final answer:
Saltation is the term for the movement of sediment particles that bounce or leap due to wind, affecting medium-sized particles such as sand.
Explanation:
When wind moves particles of sediment in a way that makes them bounce or leap, this movement is known as saltation. In the process of saltation, medium-sized particles such as sand are blown by the wind in short hops, staying close to the ground. Unlike smaller particles like silt or clay that move by suspension in the air, saltation involves sand-sized particles (diameter 0.1-0.5 mm) that are too heavy to remain suspended high in the air but can be lifted briefly above the surface. The other types of wind erosion, such as suspension and surface creep, affect different sized particles. Wind erosion is significant in shaping landscapes, especially in arid and semiarid regions where this phenomenon is more prevalent.

What is cell membrane?Cell membrane is another name for plasma membrane. Both prokaryotic and eukaryotic cells have a plasma membrane, which is a double layer of lipids that separates the inside of the cell from the external environment. The majority of this double layer is made up of phospholipids, which are a type of specialized lipid. The plasma membrane, like all cellular membranes, is made up of both lipids and proteins. The phospholipid bilayer is the membrane's fundamental structure, forming a stable barrier between two aqueous compartments. The semi-fluid living matter contained in the cell is called protoplasm (or simply plasm). This living matter or plasm is contained within the plasma membrane, a biological membrane.

how do the cells in meiosis differ from the cells in mitosis?
A. Cells in mitosis divide into new cells
B. Cells in meiosis go through one cycle of cell division
C. Cells in meiosis have unique genetic information
D. Cells in mitosis go through cycles of cell division
Answers
Answer:
C. Cells in meiosis have unique genetic information
Explanation:
Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.
The cells in meiosis differ from the cells in mitosis in the sense that cells in meiosis have unique genetic information.
Meiosis and mitosis are both types of cell division that occur in living organisms.
Further Explanation:
The statements that is NOT true about Mitosis and meiosis is
"The cells resulting from meiosis are diploid and the cells resulting from mitosis are haploid."
Further Explanation:Cell divisionCell division is the process in which cells undergo division to form other new cells.
There are two types of cell division;
Mitosis Division Mitosis is a type of division in which a parent cell undergoes division to yield two daughter cells that are similar to the parent cells.The daughter cells have equal number of chromosomes as the parent and are identical to the parent, they are therefore diploid cells.This type of cell division normally occurs in somatic cells of organisms and facilitates growth and development of organisms.Meiosis divisionMeiosis division is a type of division that occurs in gamete cells where a parent cell divides into four daughter cells that differ from the parent cells in terms of the number of chromosomes.In meiosis the daughter cells have half the number of chromosomes as the parent cells, thus known as haploid cells.Meiosis occurs in the gamete cells and facilitates sexual reproduction in living organisms.Meiosis occurs in two phases, that is, meiosis I and meiosis IIDuring the process of meiosis several processes occurs that cause genetic variation among organisms.These processes include, crossing over, independent assortment of genes, among others.Differences between cell mitosis and meiosis Mitosis occurs in the somatic cells while meiosis occurs in the gamete cells.Mitosis occurs in a single phase while meiosis occurs in two phases, that is, meiosis I and meiosis II.Mitosis involves formation of two daughter cells after cell division while meiosis forms four daughter cells after division.Daughter cells formed during mitosis are diploid while daughter cells formed during meiosis are haploid.Meiotic cell division causes genetic variation among organisms through processes such as crossover, while mitotic division does not enhance genetic variation.Cells in meiotic division have unique genetic information that is passed from the parent organisms to the offspring through when gametes from two parents fuse.Keywords: Cell division, mitosis, meiosis, crossing over, genetic variation, diploid cells and haploid cells.
