A neuron membrane potential moves from -90 mV to -80 mV in response to a brief stimulation. We would term this change in potential as a(n)
Answer:
What behavior is observed if the voltage across a neuronal membrane is set to -20 mV? The voltage-gated sodium and potassium channels both remain closed. The sodium channel opens, and Na+ ions flow out.
The membrane begins to depolarize when an external stimulus is applied. The membrane voltage begins a rapid rise toward +30 mV. The membrane voltage starts to return to a negative value. Repolarization continues past the resting membrane voltage, resulting in hyperpolarization
A neuron membrane potential moves from -90 mV to -80 mV in response to a brief stimulation this change in potential as a(n) Depolarization.
What is Hyperpolarization ?Hyperpolarization is while the membrane ability turns into extra terrible at a selected spot at the neuron's membrane, whilst depolarization is while the membrane ability turns into much less terrible (extra high quality).
Depolarization. A depolarization refers to a motion of the resting membrane ability in a extra high quality direction (in the direction of zero mV).

The model shows the flow of energy at each trophic level.
Which trophic level contains the most energy, and why?
A Producers; they have the largest number of individuals of all the trophic levels.
B Primary consumers; they have the most variety of plants from which to obtain energy.
C Secondary consumers; they release the least amount of energy into the next trophic level.
D. Tertiary consumers; they have the smallest number of individuals that need to collect energy.
Answer:
Producers
Explanation:
They get their energy directly from the sun, meaning they have the most. As if goes up the food chain, energy is lost.
what do you think might happen to the pressure in the pump during filling of the valve in the right flow tube become leaky
The pressure will decrease when valve in the right flow tube become leaky.
What is Pressure?This is defined as the force per unit area of a substance. Volume is directly proportional to the pressure of a substance.
When there is a leakage, the volume decreases which leads to a corresponding decrease in the pressure.

In the debate on global warming, what changes are listed as a result of burning fossil fuels? (select all that apply)
Question 4 options:
rising sea levels
stable temperatures from year to year
extreme weather
glacier melting
When it comes to global warming, some of its associated effects include rising sea levels, extreme weather events, and melting glaciers.
Global warmingGlobal warming refers to the rise in the average global temperature as a result of an increase in the concentration of greenhouse gases in the atmosphere.
Burning of fossil fuels increases the level of greenhouse gases such as carbon dioxide and oxides of sulfur in the atmosphere. These gases form a radiation absorbing blanket over the atmosphere and prevent reflected radiation from the sun from returning back to space.
The increase in global temperature results in the melting of the polar ice caps and glaciers with the water being discharged into the various seas of the world. Thus, causing a rise in their normal levels.
Increase in global temperature also causes extreme weather events such as drought, flooding, etc, as a result of erratic climate.

Write characteristic and function about plastids
Explanation:
CHARACTERISTICS : Plastids are double-membrane organelles that are found in the cells of plants and algae. Plastids are responsible for the manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell. Plastid is a membrane-bound organelle found in the cell of plants, algae and a few eukaryotic cells.FUNCTION : Plastids are the cytoplasmic organelles found only in plant cells. On the basis of pigments present, plastids are of three types: (i) Leucoplasts (colourless plastids) (ii) Chloroplasts (green coloured plastids)(iii) Chromoplasts (coloured plastids other than green). Leucoplasts are for storage of starch grain and oil drops. Such colourless plastids are present in underground roots, stems. Chloroplasts are mainly for photosynthesis. They are present in leaves. Chromoplasts are responsible for the characteristic colour of flower and fruit. They are involved in attracting insects, various vectors for pollination and for fruit dispersal.One characteristic shared by Bacteria and ____________ is the presence of ester bonds in their membrane lipids.

Answer:
Carbon Dioxide and Water
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
Answer:
The plant take enerygy to the sun and makes food in the leaves. carbon dioxide enters the leaf through tiny pores called Stomata. Sucrose, glucose, and fructose are found naturally in all plants, and are the basis for all food energy. The sugars that plants produce are stored in the root, leaf, seed, or fruit of the plant.

In three to five sentences, construct an argument for the claim that natural selection leads to evolution. Provide evidence for this claim, and be sure to explain how an organism shows the four parts of the process of natural selection. You may use any organism with the exception of bacteria and antibiotic resistance
Answer:
Natural selection leads to evolution due to the way reproduction works. In the example of European moths during the industrial revolution, we can see this clearly. When the industrial revolution was going, there was more pollution, hence darkening the skies and leaving ash. Moths, which before were white with occasional black spots dominated the area until pollution effected their environment. Whiter moths were eaten by bird who could easily see them against the black trees and skies. These moths could no longer reproduce, they were dead. Moths with more black could survive longer to reproduce because they were harder to see. As time went along, the moths turned mostly black, showing an example of evolution.

PLEASE ANSWER ASAP - Why are many producers needed to support a smaller number of consumers in food pyramids?
A) Because a tremendous amount of energy is lost as one moves up trophic levels.
B) Because of the exponential increase in energy gained as one moves up the trophic.
C) Because even though there is a greater number of organisms at the uppermost trophic levels, their total energy needs are far greater than those of all species combined at the lower trophic levels.
D) Because the total mass of the consumer level is far greater than that of the producers.
Answer:
A
Explanation:
Because the number of energy is lowering down as it leveled up in pyramid.
Many producers needed to support a smaller number of consumers in food pyramids because a tremendous amount of energy is lost as one moves up trophic levels, as in option A.
What is energy in an ecosystem?The energy available to an ecosystem originates from the sun and is captured by photosynthetic organisms such as plants. These organisms convert light energy into chemical energy through photosynthesis, and this energy is stored in the form of organic molecules like carbohydrates, lipids, and proteins. These organic molecules serve as food for other organisms in the ecosystem, including herbivores, carnivores, and decomposers. However, as energy moves up the food chain from one trophic level to the next, much of it is lost due to inefficiencies in energy transfer and cellular respiration.
Hence, many producers needed to support a smaller number of consumers in food pyramids because a tremendous amount of energy is lost as one moves up trophic levels, as in option A.

what is a cell division? whats another name for a cell division?
When an organism's tiny building blocks undergo a process of splitting into two parts, that's cell division. Another name for cell division is "mitosis."
If you study biology, you'll learn about cell division, when a cell divides into two smaller "daughter cells." During cell division, all the tiny elements of the cell also divide — including the cell's chromosomes, nucleus, and mitochondria. The new cells are genetically identical to the original cell. In addition to mitosis, the simple division of one cell into two, there's also meiosis, when a cell splits into four new cells, each with half the original number of chromosomes.
