The cell membrane of a retinal photoreceptor contains sodium channels that at rest (in the dark) are normally ________ and have a resting potential that is ________ compared to other neurons.
Answer:
open; depolarized
Explanation:
The photoreceptors, i.e., rods and cones, are specialized neurons located in the retina. These cells convert sunlight into electrochemical signals which are interpreted by the central nervous system. The cGMP-gated channels that are expressed in photoreceptor plasma membranes have a major role in this process by regulating the flow of sodium (Na+) and calcium (Ca2+) ions in the outer side of the membrane via changes to cyclic guanosine monophosphate (cGMP) levels which are induced by light. In the dark, high cGMP levels maintain channels in an open state, thereby allowing the passage of Na+ and Ca2+ ions to flow into the outer segment of photoreceptors in order to maintain them in a depolarized state.

The difference between Prokaryotic cell and Eukaryotic cell are;
[tex]\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}[/tex]
Explanation:
Prokaryotic cells
The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells
Eukaryotic cells
Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

At first the virus was very deadly to the rabbits, but over the years, the virus became less deadly. Explain what might have happened to the rabbit population and why the virus became less dead
Answer:
Natural Selection
Explanation:
Overtime the the animals that had a natural immunity to the disease bred and produced offspring that also had this immunity, while the other animals that didn't dies off. So the population would have become smaller, but only for a little bit. Overtime this immunity will become more common in the population.

What is one reason that carbon dioxide is increasing in the atmosphere
today? *
Answer:
Concentrations of carbon dioxides are rising mainly due to energy-burning fossil fuels. Fossil fuels such as carbon or oil include carbon plants which, over the years, are photosynthesized in the atmosphere; in a few hundred years we have returned this carbon to the air
Explanation:
Even fundamental human functions — eating inhalation and digestion — generate CO2. In the life cycles of the earth, it is an essential chemical. Active plants and trees are absorbing CO2 and turning it into food with sunlight and water. There are problems when more CO2 is emitted than is absorbed by our vegetation. Activities to produce high carbon dioxide include:
Consuming electricity: Fossil fuels emit CO2, with coal emitting twice as much gas as oil. Worldwide, 85% of energy is generated by fossil fuels. As China and India continue to industrialize, the number of coal-burning plants will rise. Today, power generation represents 41 percent of CO2 emissions in the United States.Transportation: Locomotive is the second greatest source for U.S. CO2 emissions for business or pleasure. Travel is also a factor internationally. A cruise ship study indicated that holidays at sea produce 12 times more CO2 than on land. 41,000 tonnes of CO2 was generated at Denmark's 11-day worldwide Copenhagen Conference on Climate Change. U.S. representatives alone produced sufficient CO2 to fill 10,000 Olympic pools.Building: Manufacturing produces large amounts of CO2, yet only represents 2% of US emissions. The most serious offenders are the manufacture of iron and steel and cement. These businesses use huge amounts of thermal energy to turn commodities into building products.Deforestation: Trees are powerful organisms that absorb CO2 from the air and remove it. It stops the process by cutting them down. While deforestation is a tiny source of increasing CO2 in the U.S., 20 percent of global CO2 emissions are due to forest loss. Fuel-burning trees and natural forest material breakdown also generate CO2.How Many Years Ago Was Parachute Invented?????
If YOU WANT BRAINLEST THEN ASAP
Answer: 4,000 years ago
The parachute was invented 4,000 years ago, when Chinese observers noticed that air resistance slowed free-falls. Legend states that a safe jump was made from a granary using two bamboo hats. In the 800s, Abbas Ibn "Armen" Firnas jumped off a tower in Cordova (Iberian peninsula) using a large cloak like a wing.
Which factor causes the shape of a fatty acid to be straight?
Explanation:
Saturated Fatty Acids
The primary components of fatty acids are carbon, hydrogen, and oxygen. When carbon atoms bond together, they form a single bond and can exhibit a zig-zag shape. When the overall molecule is seen, the entire fatty acid appears as a fairly straight line.
Where are neutrons located?
O A. Outside the nucleus of an atom
O B. Inside the cell membrane
O C. Inside the nucleus of a cell
O D. Inside the nucleus of an atom.
Answer:
D. Inside the nucleus of an atom.
Explanation:
The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
Answer:
D
Explanation:
Since this is a biology/chemistry question, you have to be careful that you use the right term. You must be talking about atoms. So B and C are both incorrect because the word cell is used as the main location.
What about A and D? The atom is used and those two are the ones you need to consider. A neutron gives its home address as the nucleus. It is part of the nucleus. So A is incorrect. A neutron is inside the nucleus.
That leaves with D and that's the answer.
Name the gas. 1. Used in respiration 2. Produced in respiration 3. Used in photosynthesis 4. Produced in photosynthesis
Answer: Oxygen
Explanation:
Explanation:
The fixation or reduction of carbon dioxide is a process in which carbon dioxide combines with a five-carbon sugar, ribulose 1,5-bisphosphate, to yield two molecules of a three-carbon compound, glycerate 3-phosphate, also known as 3-phosphoglycerate.

Besides the interaction between animals and plants, what other factors may be involved in the carbon and oxygen cycles?
Answer: .co2
Explanation: co2
The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.
Which factor contributes to the carbon cycle?
Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
How do plants and animals interact with the carbon cycle differently from one another?Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

Animal life changed greatly during the Cambrian explosion, with some groups expanding in diversity and others declining. What are the current hypotheses that explain these trends?
A. Global climate changes.
B. Atmospheric changes.
C. Predator prey relationships.
D. Appearance of the marine top predator.
E. Changes in the regulations of develop.
F. Radiation of numerous terrestrial groups.
Answer: Options A,B,C, and F
A. Global climate changes.
B. Atmospheric changes.
C. Predator-prey relationships.
F. Radiation of numerous terrestrial groups.
Explanation:
Due to increasing natural disasters (such as volcanic eruption) and arthropological activities (such as mining) that led to the emission of harmful gases, changes in the atmosphere and overall climatic conditions is established.
They saturate the atmosphere and due to limited carbon sinks to absorb them, they alter the climatic parameters like temperature, rainfall, and relative humidity.
The effects of change in climatic parameters are flooding, habitat destruction, increased predation, and among others. Thus, leading to dispersal of some animal species and decline of many others.
Predator-prey relationship also plays an important role in the expansion (likely through migrating from danger) and in most cases decline of some animal species, especially when there's limited prey species to go round for the predators.

The government of a flood prone region wants to implement some measure to reduce risk of floods. Which method is likely to reduce the risk of floods in that region
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
