Answer:
The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed.
Explanation:
The process of the formation of RNA from DNA is called transcription.
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to its DNA template as the enzyme, RNA polymerase matches the complementary bases to the original DNA strand and then initiates the process of RNA synthesis. Once the strand gets completed, the process got terminated.
Hence, the correct answer is "The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed."

Sodium movement into your neurons results depolarization which activates voltage gated sodium channels in the cell membrane. More sodium enters the cell resulting in more depolarization and the action potential moves down the axon.
positive or negative feedback?
The entry of sodium into your neurons results in depolarization which activates voltage-gated sodium channels. This represents an example of a positive feedback mechanism.
What happens to sodium channels during depolarization?During the depolarization phase, the gated sodium ion channels on the neuron's membrane suddenly open and allow sodium ions (Na+) present outside the membrane to rush into the cell. As the sodium ions quickly enter the cell, the internal charge of the nerve changes from -70 mV to -55 mV.
Positive feedback mechanisms control self-perpetuating events that can be out of control and do not require continuous adjustment. In positive feedback mechanisms, the original stimulus is promoted rather than negated. It increases the deviation from an ideal normal value.
Therefore, the entry of sodium into your neurons results in depolarization which activates voltage-gated sodium channels. This represents an example of a positive feedback mechanism.

The only people with Rh negative blood are people who have inherited two recessive alleles for this trait. But some people who are colorblind have inherited only one recessive allele for this trait. Explain why these traits are different in terms of how many recessive alleles are needed to produce the recessive phenotype. Hint: Think about the above problem and sex chromosomes versus autosomes.
The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.
What are the blood type and Color-blindness inheritance patterns?
⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.
The allele Rh+ dominates over the allele Rh-.
Genotyopes and Phenotypes are as follows,
Individuals Rh+Rh+ express the possitive phenotypeIndividuals Rh+Rh- express the possitive phenotype Individuals Rh-Rh- express the negative phenotype.To express Rh-, a person must inherit two recessive alleles from their parents.
⇒ Color-blindness is an X-linked condition coded by a recessive allele.
As most sex-linked genes, it is transmitted together with the X chromosome.
The phenotype depends on the number of recessive alleles and the sex of the person.
Genotyopes and Phenotypes are as follows,
X⁺X⁺ women have normal sight.X⁻X⁻ women are completely color-blinded X⁺X⁻ women are partially color-blinded. X⁺Y Men are not color-blinded X⁻Y Men are color blinded.In this case, only one recessive allele is enough to express the affection.
In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

Please use the following information to answer the questions below. The southern grasshopper mouse feeds regularly on the Arizona bark scorpion, the most venomous scorpion in the United States. While attempting to capture the scorpion, the mouse usually gets stung multiple times by the scorpion but does not seem to be affected. While attempting to capture the scorpion, the mouse's heart rate increases, and there is an increase in epinephrine in the mouse's blood. What nervous system division is responsible for the mouse's physiological state
The sympathetic nervous system is responsible for the mouse's physiological state.
The nervous system divides into the central nervous system and peripheral nervous system.
In the central nervous system, we have the brain and the spinal cord.
The peripherical nervous system, which is all the nerves that are not in the spinal cord or the brain, is divided into:
The somatic nervous system, which is the one that makes the conscious movements of our body.The autonomic nervous system consists of:-Sympathetic nervous system. It is the one that works under stress. It gives the fight or flight response preparing the body for a dangerous situation. It increases the heart rate and epinephrine's release. Epinephrine is a hormone that helps in this response stimulating the sympathetic system.
-Parasympathetic nervous system. It is the one that works in calm situations, like after we ate, regulating digestion, and trying to save energy for any upcoming event.
In conclusion, as there is an increase in epinephrine and heart rate, and the mouse is "fighting" against a scorpion, the nervous system division responsible for this physiological state is the sympathetic nervous system.

Which process most likely led the beach to form?A. Rock on the beach being weathered by the water and falling apart.B. Sediment being deposited as an ocean breeze slows down along the coastC. Palm trees breaking apart large pieces of granite and limestoneD. Coral reefs in the ocean breaking down and being deposited ashore.
Sediment being deposited as an ocean breeze slows down along the coasting process most likely led the beach to form.
The weathering and coastal erosion of surrounding land formations lead to the creation of beaches. Sediment is eroded and carried by the water as waves from the ocean strike these land features.
When waves deposit sand, sediment, and various rocks along the shoreline, a sea beach structure is created. They eventually become smooth from being tossed around by the waves. To depict local geography, the sediments typically mirror one another.
Sand seen on beaches is mostly a result of the weathering of the ground (such as the natural erosion of coastal bluffs). Coral and other oceanic creatures can also produce sand. However, rivers and streams provide the majority of the sand found on beaches around the world.

the impression of its leaf on a sheet of paper? Think and explain the answer.
Answer:
No, it is not possible to determine whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper. This is because the root system of a plant is hidden underground and cannot be seen from the surface. The shape and size of a leaf can provide clues about the type of root system a plant has, but the impression of a leaf on a sheet of paper does not provide enough information to definitively identify the type of root system.

How does the pattern of starch storage relate to the distribution of chlorophyll
Answer: The pattern of starch storage is closely related to the distribution of chlorophyll in plants
Explanation:
Chlorophyll is a green pigment that helps plants to absorb light energy and convert it into chemical energy via photosynthesis. Starch, on the other hand, is a complex carbohydrate that is used by plants as a storage form of energy.
Chlorophyll is predominantly found in the chloroplasts of plant cells, which are responsible for carrying out photosynthesis. The chloroplasts are found mainly in the leaves of the plant, where they are exposed to light. Therefore, the highest concentration of chlorophyll is found in the leaves of the plant.
Starch, on the other hand, is synthesized in the chloroplasts of the plant cells during photosynthesis. The starch is then stored in different parts of the plant, depending on the plant species. Some plants store starch in their leaves, while others store it in their stems, roots, or even fruits.
In general, plants that have a high concentration of chlorophyll in their leaves tend to store more starch in their leaves. This is because the leaves are the primary site of photosynthesis and starch synthesis. However, some plants, such as potatoes, store most of their starch in their underground tubers.
Therefore, the pattern of starch storage in plants is closely related to the distribution of chlorophyll, with the highest concentrations of both found in the leaves of the plant. However, the specific pattern of starch storage can vary between different plant species, depending on their individual needs and adaptations.
