Answer:
1. The difference in charge across the membrane is called the - membrane potential.
2. It is measured in mV
3. At resting potential, the charge of the outside of the neuron is 70 mV less negative than the inside
4. Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n) Action Potential
5. This causes the charge outside the cell to temporarily become positive and the inside to temporarily become negative
6. When the action potential arrives at the axon terminal it reaches a junction called the Chemical Synapse

Stars ----- Planets
Alike and Different
Answer:
Explanation:
Same
Most stars are round. Planets are too.Most stars are large distances from each other. So are planets (not as large though)Most stars have colors associated with them. So do planets.Different
Stars are many magnitudes of temperature warmer than planets.Stars are mostly gaseous. Planets are solid.Stars are made of fundamental materials. Most planets have many elements on their surface and atmosphere if they have an atmosphere.The star's diameter is many times larger than the planets.Generally speaking, the planet's density is between 1.5 to 5 times more than the stars.is the transforming factor made of proteins?
Answer: Understand about transformation as part of this. ... Is protein the transforming factor? protein-destroying enzymes---made the strains grow so concluded that protein doesn't transform because the bacterial colonies were still transformed. He concluded that protein could not be the transforming factor.

What mechanisms of evolution could be involved in the evolution of wolves and dogs? *
Natural Selection and Genetic Drift
Diffusion and Osmosis
Photosynthesis and Cellular Respiration
Natural Selection and Genetic Drift
evolution refers to the change in the characteristics of a species over several generations and relies on the process of natural selection.
there are four types of mechanism of evolution:

Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!

(Will give brainliest if correct and no links) Based on the image in figure 2, would the creation of one type of kidney cell be sufficient in forming a functioning kidney? Explain why?
Answer:
Yes.
Explanation:
The creation of one type of kidney cell will be sufficient in forming a functioning kidney because one type of cells allow the kidney to perform its one function i.e. filtering of blood. Epithelial stem cells are the cells that is responsible for the function of a kidney. The kidneys have only epithelial stem cells which performs only one function which removing water material, excess salts and water from the body. so we can say that one type of kidney cell is sufficient for the functioning of kidney.
What happens to the heat and moisture from the ocean?
a.) They rise into the atmosphere
b.) They sink into the warm deep current
c.) They become precipitation
d.) They move parallel to the hurricane
NEED ASAP!!
Answer:
The answer is A
Explanation:
When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.
in pea plants, purple are dominant to white.
complete the chart showing the genotypes and phenotypes possible.
someone help me i’m kinda lost on how i do this
Answer:
PP (genotype) - Purple (Phenotype)
Pp (Genotype - Purple (Phenotype)
pp (Genotype) - White (Phenotype)
Explanation:
The genotype allele combinations, in order to for purple to be dominant there are three possible genotypes
*Capital P represents a purple dominant allele
*Lowercase p represents a white recessive allele
(Alleles are the variants of a certain gene, ex: brown eyes, green eyes, etc. )
A Dominant always overpowers the recessive, the only way for a recessive to show would be to have two recessive alleles from both parents
ex: Green eyes recessive to Brown
B - Brown bb = green eyes (from dad)
b - green bb = green eyes (from mom)
this means that their child would have green eyes because there is no brown present
So for your pea plants to be purple
Pp = Purple pp = white
PP = Purple (yes there can be white recessive present, it just might not appear as a plant because of the percent of purple)
The colors or observations we see as the plant are the phenotypes
so the colors I have listed would be the phenotypes
Don't get alleles and phenotypes confused, alleles are the various forms of a gene, and phenotypes are what we see when the gene is brought through.

Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. Recall that the normal range for the hematocrit for a female is 37 - 47%, and the normal range for the hemoglobin level for a female is 12 - 16 g/100 ml. Describe hemoglobin and hematocrit values for the female with iron-deficiency anemia. They were both below normal. The hemoglobin was normal, and the hematocrit was below normal. They were both normal. The hemoglobin was below normal, and the hematocrit was normal.
Answer:
The hemoglobin was below normal, and the hematocrit was normal.
Explanation:
Hemoglobin is an essential protein in the bloodstream, as it is primarily responsible for the transport of oxygen throughout the body. It is also responsible for the red coloration of the blood, as it is present in the red blood cells. The hematocrit, in turn, is a laboratory parameter to determine the amount of red blood cells in the blood and also to determine the total blood volume.
Although the results presented by the hematocrit are important in determining whether a person has anemia, women with normal hematocrit values may be anemic, primarily because the hematocrit results may be associated with the amount of water in the blood. What is essential to determine if a woman is, in fact, with anemia, due to iron deficiency, is the hemoglobin values that are below normal.
Which is an example of genetic diversity? PLS HELP temperate rain forest and a tropical rain forest bees, jack rabbits, diamondback rattlesnakes bacteria, garter snakes, tigers variations in a flock of starlings
Answer:
temperate rain forest and a tropical rain forest bees.
Explanation:
The temperate rain forest and a tropical rain forest bees is the example of genetic diversity because the same organisms has different features which allows them to live in different climatic conditions due to their variation in genetics. The environment of temperate rain forest is different from tropical rain forest so the bees specie that live in both environment are different from one another in their genetic makeup and which is an example of genetic diversity.
Why are the carbonate ion level in the water decreasing?
Answer:
Carbon dioxide reacts with seawater to form carbonic acid, which releases hydrogen ions, reducing pH.The additional hydrogen ions released by carbonic acid bind to carbonate (CO32-) to form bicarbonate (HCO3–), decreasing the amount of carbonate in the water.

Why do we exhale more carbon dioxide than we inhale?
Answer:
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.
Answer:
because our bodies take in O and put out CO2
Explanation:
O is Oxygen
and CO2 is Carbon dioxide

1.habitat
2.biome
3.environemnt
4.ecosystem
Answer:
The correct answer is 4.ecosystem.
Explanation:
An ecosystem is a system, that is, a set of elements that interact with each other, in which such elements are: physical environment, living beings and their interactions (predator-prey, parasite-host, competition, symbiosis, pollination, distribution of seeds , etc.) The interrelation between living beings (competition, parasitism, etc.) occurs through cycles of matter and energy flows on which the functioning of the entire ecosystem depends.
