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.

Which of the following is true of red blood cells? A. They live for only 120 days. B. They have multiple Nuclei. C. They live for only about 20 days. D. Once created in bone marrow, they circulate for our lifetime.
A. They live for only 120 days is correct. They are created in the bone marrow and destroyed in the spleen "red blood cells graveyard"
B. They have multiple Nuclei. Red blood cells don't have a nucleus but some can present structures called Jolly's bodies that are small pieces of the nucleus that they lost in the differentiation process
C. They only live for only about 20 days. No, red blood cells live for about 120 days
D. Once created in bone marrow, they circulate for our lifetime. Again, they have a limited lifetime

Answer:
Option 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.

A marine biologist explains that salmon populations change over time because of differential reproduction. What is "differential reproduction"?
Some organisms in a population lay eggs, while others produce sperm.
Some organisms in a population produce more male offspring than others.
Some organisms in a population produce more offspring than others.
Some organisms in a population reproduce in rivers, while others stay in the ocean.
Differential reproduction means that some organisms in a population produce more offspring than others.
Differential reproduction refers to the difference between individuals in a population and how many offspring they are able to leave.The best adapted organisms to a given environment will leave more offspring than those who are not well adapted. Differential reproduction depends on the natural

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

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

Why are saprotrophs so important to a marine food web?
Answer:
They break down dead organisms and recycle nutrients. They directly help to maintain the population sizes of different predators. They primarily eliminate toxins from the water that can harm phytoplankton.
Explanation:
Hope it helps I found it on brainly
Answer:
They break down dead organisms and recycle nutrients.
Explanation:
Saprophytes are the living organisms that feed upon dead organisms such as plants, animals, and their decaying products. They contribute to the food web because they help in clearing up the biological waste from the environment and make the resources after degradation available to the plants as soil nutrients. Therefore, helps in nutrient recycling in an ecosystem.

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
