In order for a dead organisms remains to become fossilized certain conditions must be met. summarize three of these conditions.

Answers

The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition. This does make the fossil record biased because animals with soft bodies are less likely to form fossils. It also means that particular environments will not help fossils form because the remains must be buried rapidly and escape the detection of scavengers.
4. Describe three different methods of fossilization.
Organisms can be buried and preserved in substances such as frozen soil, volcanic ash, sediment, ice, oil, and amber. This process preserves even the soft parts. Hard parts such as shells, teeth, bones, and wood can also be more easily preserved because they resist weathering. Hard parts can also become altered due to carbonization (leaves only a thin film of carbonaceous material), petrifaction (gets replaced by minerals in water turning it to stone), and replacement (hard parts dissolve and get replaced by calcite, silica, dolomite, and iron compounds)

The vast majority of deceased organisms vanish without a trace, so fossilization is a rare process.

What are the conditions that favor fossilization:

Hardbody parts (bones, teeth, shells) will fossilize; soft body parts will not but may leave traces (e.g. imprints)

Remains preserved (protection against scavenging, erosion, and environmental damage)

There is a lot of pressure to get the remains mineralized (i.e. turn hard body parts into fossilized rocks)

Anoxic (low oxygen) conditions are used to protect against oxygen damage and to prevent saprotroph decomposition.

Thus, we can conclude that hardbody parts remain preserved, and high pressure and anoxic conditions are required during fossilized.

*PLEASE ANSWER TY* Which gas makes up the majority of air pollutants? a.) sulfuric acid b.) sodium hydroxide c.) carbon monoxide

Answers

Answer:

carbon monoxide

Explanation:

sulfuric acid is litterally acid

sodium hydroxide..... common now

Carbon monoxide (c.) is the gas that makes up the majority of air pollutants.

What is carbon mono oxide?

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is produced by the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, coal, and wood. It is a highly toxic gas and can be harmful to both humans and animals.

When inhaled, carbon monoxide enters the bloodstream and binds to hemoglobin, the molecule responsible for carrying oxygen to body tissues. This binding affinity is much stronger than that of oxygen, resulting in reduced oxygen delivery to organs and tissues. As a result, exposure to high levels of carbon monoxide can lead to symptoms such as headache, dizziness, nausea, confusion, and in severe cases, loss of consciousness and death.

Carbon monoxide is a significant air pollutant, often found in areas with heavy traffic, industrial emissions, and improper ventilation. It is important to have proper ventilation systems and to use carbon monoxide detectors to minimize the risk of exposure to this dangerous gas.

Explanation: You can often recognize a carbohydrate by its suffix – ose (e.g. glucose, sucrose, cellulose, etc.)

Carbohydrates are made of elements Carbon , hydrogen and oxygen! Carbohydrates occur as sugars and polymers. The simplest form which is monosaccharides and disaccharides are sugars and polysaccharides are polymers ! Disaccharides are made of two monosaccharides formed my a glycocidic bond ! For example maltose is made of 2 glucose molecules and sucrose is made of glucose and fructose and lactose is made of glucose and galactose! Monosaccharides bind as a long chain structures or branches and forms a polysaccharide! Usually 100 to 1000 monosaccharides are included ! For example cellulose is made of glucose as it’s monomer and inulin which is present in dalia tubers are made of fructose ! We can obtain monosaccharides by hydrolysis of disaccharides and polysaccharides

Classification of Living Organisms

Each organism is different from all others to a lesser or greater extent. Obviously, we and our friends have a lot in common when we compare ourselves with a monkey. But suppose we were to add a cow to the comparison? We would then think that the monkey has a lot more in common with us than with the cow.

Think of all the different forms in which life occurs on earth. On one hand we have microscopic bacteria of a few micrometre in size. While on the other hand we have blue whale and red wood trees of california of approximate sizes of 30 metres and 100 metres repectively. Some pine trees live for thousands of years while insects like mosquitoes die within a few days. Life also ranges from colourless or even transparent worms to brightly coloured birds and flowers.

This bewildering variety of life around us has evolved on the earth over millions of years. However, we do not have more than a tiny fraction of this time to try and understand all these living organisms, so we cannot look at them one by one. Instead, we look for similarities among the organisms, which will allow us to put them into different

classes and then study different classes or groups as a whole.

In order to make relevant groups to study the variety of life forms, we need to decide which characteristics decide more

fundamental differences among organisms. This would create the main broad groups of organisms. Within these groups, smaller subgroups will be decided by less important characteristics.

Describe wavelength, amplitude, and frequency in relationship to vision and hearing

Answers

Explanation:

Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions. Waveforms of different types surround us at all times, however we only have receptors which are sensitive to specific types of wavelengths. In this section, we describe the physical properties of the waves as well as the perceptual experiences associated with them.

AMPLITUDE AND WAVELENGTH

Two physical characteristics of a wave are amplitude and wavelength (figure below). The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

 

The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak.

 

   Wavelength is directly related to the frequency of a given wave form. Frequency refers to the number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. Longer wavelengths will have lower frequencies, and shorter wavelengths will have higher frequencies 

Wavelength and frequency are inversely related so that longer waves have lower frequencies, and shorter waves have higher frequencies. In the visual system, a light wave's wavelength is generally associated with color, and its amplitude is associated with brightness.

In which process does RNA polymerase help synthesize mRNA from a DNA template? transcription translation translocation transportation

Answers

Answer: Transcription

Explanation:

RNA polymerase is an enzyme that plays a key role in the process of transcription, which is the synthesis of mRNA (messenger RNA) from a DNA template. Therefore, option (A) is correct.

What is transcription?

Transcription is the process by which the information contained in DNA is used to synthesize RNA molecules. It is the first step in the process of gene expression, in which the genetic information stored in DNA is used to produce the proteins and other molecules that carry out the functions of the cell.

During transcription, an enzyme called RNA polymerase reads the DNA sequence and synthesizes a complementary RNA molecule, called mRNA, which carries the information from the DNA out of the nucleus and into the cytoplasm, where it can be used to guide the synthesis of a protein.
