Answer:
The process of nerve impulse transmission by means of an action potential involves the processes of depolarization, repolarization, hyperpolarization and restoration of resting memebrane potential.
Explanation:
In order for a neuron to receive and transmit a message it must be in a polarized state. While in this rest state there are more sodium ions outside the cell membrane while potassium is prevalent inside the cell. This causes the neuron to maintain a neutral charge. Once the action potential arrives at its dendrites, a nerve cell will shuttle the message down its own axon and to the next neuron via its axon terminal. This impulse will cause the cell to become depolarized and will effectively change the charge of the neuron to a poositive charge. After sodium rushes into the cell, the potassium will rush out in order to restore its resting memebrane potential. Once the impulse reaches the axon terminal, it is used to open voltage- gated calcium channels releasing calcium ions that stimulates a neurotransmitter to continue the message to the next neuron. The neuron then undergoes a repolarisation when all ions are repositioned with help of the voltage-gated ion channels.

What enzyme opens up in the DNA into two single strands ?
Answer:
DNA helicase
Explanation:
The image of this question shows the replication of DNA into two identical copies. However, before this occurs, the double-stranded DNA needs to be unwound or separated so that each single strand can serve as a template for a new strand.
An enzyme called DNA helicase is responsible for the separation of the DNA molecule into single strands. After which, DNA polymerase begins to add nucleotides to each single strand of DNA.

Orange lilies get their color from two genes, a
gene for yellow pigment and a gene for pink
pigment. Each gene has a dominant allele and a
recessive allele: Y and y for the yellow gene, P
and p for the pink gene.

Actually Welcome to the concept of Genetics and color.
According to the above condition, we will get the remaining results of crisscross as,
4.) YYPp ==> Yellow
5.) YyPp ==> Orange (both expressed)
6.) yyPp ==> Pink
7.) YYpp ==> Yellow
8.) Yypp ==> Yellow
9.) yypp ==> White
In this case, we have to recognize the concepts of genetics, so the phenotype for each exercise color:
YYPP=orangeYyPP=orangeyyPP=pinkYYPp=orangeYyPp=orangeyyPp=pinkYYpp=yellowYypp=yellowyypp=whiteWhat is a phenotype?Phenotype is an important concept adopted in Genetics and is usually defined as the set of observable characteristics of an organism. In this sense, the morphological and physiological characteristics of an individual are included in this set.
So from the information given in the statement we have that:
When both pigments are expressed, the flowers appear orange.When only one pigment is expressed, the flowers are either yellow or pink.When neither pigment is expressed, the flowers appear white.Phenotypes are expressed by the following colors:
YYPP=orangeYyPP=orangeyyPP=pinkYYPp=orangeYyPp=orangeyyPp=pinkYYpp=yellowYypp=yellowyypp=whiteSee more about phenotype at brainly.com/question/20730322

Describe Charles Darwin's theory of natural selection
Answer:
it sghwbdhfbwahdfk
Explanation:
Answer:
Explanation:
Darwin's Theory of Evolution by Natural Selection
More individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive.Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Significado del acoplamiento entre CTE y FosOx, es de bioquimica si alguien me puede ayudar por favor
Answer:
La teoría quimiosmótica indica que la cadena de transporte de electrones (CTE) y el proceso de fosforilación oxidativa (FosOx) están acoplados por un gradiente de protones.
Explanation:
La teoría del acoplamiento quimiosmótico propuesta por Peter Dennis Mitchell permite entender cómo el ADP se fosforila a ATP en mitocondrias y cloroplastos. La energía que se libera durante la cadena del transporte de electrones es utilizada por la célula para crear un gradiente de protones a través de las membranas internas de mitocondrias y cloroplastos. Subsecuentemente, la energía potencial creada a partir de este proceso es liberada por el movimiento de protones a favor de un gradiente electroquímico. Finalmente, la energía potencial creada a partir del flujo de electrones es acoplada a la fosforilación oxidativa para sintetizar enlaces fosfato de alta energía en el ATP a partir de ADP y fosfato (Pi).
at what point did the climate began to fluctuate more severely ? (2 points )
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms. In these two reactions, different types of catalyst are used which helps in speedup the chemical reaction so we can conclude that these two reactions have different reactants, bonding and catalysts in their chemical reaction.
Explain the causes of the seasons
Answer:
weather
Explanation:
A company called Sierra Pacific Industries is destroying forests by a destructive and non-sustainable practice called clearcutting. This is being done at an alarming rate in specific counties in California.
A.Primary Succession
B.Secondary Succession
Answer:
Secondary succession.
Explanation:
Clearcutting leaves an area barren. It is a horrible practice and is opposed by every environmental group. There are better ways of logging without destroying the plant life present there. This is secondary succession because plant life did exist in the area that clear cut and will again if the logging company or the government will replant the area.
describe the process of cell division that occurs to produce daughter cells during asexual reproduction
Answer:
The primary mechanism by which organisms generate new cells is through cell division. During this process, a single "parent" cell will divide and produce identical "daughter" cells. In this way, the parent cell passes on its genetic material to each of its daughter cells. ( Hope it helps )

Answer:
Después de la fecundación, la célula recién formada llamada cigoto lleva a cabo divisiones sucesivas hasta desarrollar un nuevo individuo. Estas divisiones se llevan a cabo mediante el proceso llamado segmentación.
Explanation:
Luego de que se produce la fecundación del óvulo y se forma el cigoto, los 3 a 4 días que le siguen abarca un proceso llamado segmentación. En este proceso se producen sucesivas divisiones celulares dando blastómeros, los cuales son células que forman el embrión y a las estructuras que este necesita para desarrollarse. La segmentación es un proceso que ocurre en las trompas de falopio mientras el cigoto se desplaza hacia el útero donde se implantará.
