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.

A- A.
Answer:
See below
Explanation:
This new model perhaps better explains the elements required in order for photosynthesis to take place. Sunlight, water, carbon dioxide are essential for the plant so it can produce it own food. Someone who is not previously familiar with the process of photosynthesis needs to start from these basics and then further build on this knowledge.
Answer:
This model shows all the major molecules involved in the Calvin cycle and how they change at each stage of the process. This added detail would clarify that the Calvin cycle is a series of complex steps. The student’s original model didn’t show this breakdown at all, and it shows only the final products. This model also shows the number of each molecule created, which the original model doesn’t do.

Hyponatremia is a condition in which the sodium in the blood is too low. Uncontrolled spasms, which are sudden, involuntary contractions of muscles, are among the symptoms of hyponatremia. Why do they occur? A. Sodium is needed to generate an action potential. B. Sodium makes up most of the myelin sheath. C. Sodium is the signaling molecule that transmits impulses across a synapse. D. Sodium controls voluntary movement, and potassium controls involuntary movement. Reset Next
Answer:
A. Sodium is needed to generate an action potential.
Explanation:
Action potentials are generated by the special types of the voltage-gated channels which are embedded in the plasma membrane of the cell.
These channels are shut when the membrane potential is near zero and the voltage-gated channels open only when the membrane potential is more than the threshold voltage.
When the channels are open then they allow the flow of sodium ions which ultimately changes the electrochemical gradient which rises the membrane potential. This rise in membrane potential generates the action potential.
Microorganisms of a family of fungi, called the Lepiotaceae, live with leaf-cutter ants. The ants collect fresh leaves to grow the
fungus, and then they feed the fungus to their larvae. Another type of microorganism, a fungus of the Ophiocordyceps family, also
has a relationship with a type of ant. The spores of the fungus attaches to carpenter ants in order to complete its life cycle. The
spores spread into the ant's body and causes behavioral changes in the ant, eventually causing the ant's death.
What does this information demonstrate?
Answer:
Between the Lepiotaceael and the eaf-cutter ants, there is what we call mutualism. They both depend on each other buh no harm is done.
But between Ophiocordyceps family and the carpenter ants, it is called parasitic relationship. The Ophiocordyceps harms the carpenter ants.

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

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.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. How does the design of your experiment control for outside factors that may affect the results?
Answer:
yes the fertile soil will grow faster and taller
Explanation:
the fertile soil will grow faster because it has what the plant needs
What is one of the reasons why Gregor Mendel chose to study pea plants? They exhibit only a single trait. They produce flowers. They grow very slowly. They reproduce sexually.
Answer:
They reproduce sexually.
Explanation:
They exhibit multiple traits and grow quickly.
One of the reasons why Gregor Mendel chose to study pea plants is because they reproduce se-x-ually
Gregor Mendel's study of pea plantIn Gregor Mendel's work on pea plants, he discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Parental genes are randomly separated to the reproductive cells so that s-ex cells contain only one gene of the pair

1. Latitude. Kuala Lumpur is located in the equatorial zone, near the equator, so it receives a lot of sun for the entire year, and this explains its warm climate.
2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.
3. Jakarta: in fact, it is located at a similar altitude of Kuala Lumpur (just in the opposite hemisphere), in the equatorial zone, while Baltimore is located much more north, so in a colder region.
4. Because they are located at approximately same latitude (just in the opposite hemisphere), so they are more or less same distance from the equator, and they receive more or less same amount of sun light, therefore they have similar climate.
1. it is Latitude. Kuala Lampur is located in the equatorial zone, (near the equator,) so it receives a lot of sun for the entire year, and this explains its warm climate.
2. The main reason for this difference is the altitude: while Minsk is located at 280 meters over the sea level, Banff is located at approximately 1400 meters over the sea level. As the altitude is higher, the average temperature is lower.
