when placed in the same container, oil and water do not mix because
Oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.
What are the characteristics of water?The characteristics of water are as follows:
It is a universal solvent that is polar in nature. It possesses high heat capacity and heat of vaporization. It has properties like cohesion and adhesion. The solid form of water is less dense as compared to its liquid form.Due to differences in their polarity, the molecules of water and oil are not intermingled with each other. Due to this, the polar compounds are dissolved in a polar solvent while non-polar compounds like oil are dissolved in a non-polar solvent. Thus, the molecules of oil will finally stick to each other and are immiscible with water.
Therefore, oil and water do not mix because mix each other because water is a polar solvent while the molecules of oil are non-polar in nature.

You conduct a voltage clamp experiment in which you hold the presynaptic terminal of a glutamatergic neuron (a neuron that releases glutamate) at 0 mV. When you treat the terminal with TTX, an inward current is recorded. Which ion and ion channels are responsible for the current you observe? Group of answer choices Calcium; ligand-gated non-specific cation channels Sodium; ligand-gated non-specific cation channels Calcium; voltage-gated calcium channels Sodium; voltage-gated sodium channels Potassium; voltage-gated potassium channels
Answer:
Calcium; voltage-gated calcium channels
Explanation:
Voltage-dependent calcium channels represent a group of voltage-gated ion channels and they are recognized to be primary mediators of calcium entry induced by depolarization. These channels are localized in the membrane of excitable cells such as, for example, neuron cells. The potential difference across the membrane of neuron cells without physiological activity is named resting membrane potential. When there is no action potential, voltage-dependent calcium channels are normally closed.

What happens when ionic compounds dissolve in water?
a) Cations and anions are released into the solution
b) They split up H2O molecules into H and O
c) They stick to the wall of the beaker
d) They are transformed into non-metals
Taking into account the definition of ionic compound, the correct answer is option a): Cations and anions are released into the solution.
First, you have to know that an ion is an electrically charged particle.
Ionic bondSo, the ionic bond consists of the electrostatic attraction between ions with charges of opposite sign. This type of bond occurs between the chemical combination of a metal and a nonmetal.
Ionic compoundFinally, an ionic compound is made up of positive and negative ions, held together by electrostatic forces of attraction. Atoms of metallic elements tend to lose one or more electrons when combined with non-metallic atoms, and non-metallic atoms tend to gain one or more electrons.
As a result of this transfer of electrons, the metallic atom becomes a positive ion (called a cation) and the non-metallic atom becomes a negative ion (called an anion).
In other words, an ionic compound is a chemical compound made up of two substances with a significant difference in their electronegativities. It is formed preferably between metals and non-metals.
Ionic compounds dissolve in waterSo when ionic compounds dissolve in water, they separate into cations and anions, electrolytic dissociation occurs. This is because water becomes a conductor of electricity.
In summary, the correct answer is option a): Cations and anions are released into the solution.

Which is FALSE? First exclude the four correct answers. Which is FALSE? First exclude the four correct answers. The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers. Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow. Sugar produced in photosynthesis must support the plant’s energy needs both day and night. Leaves perform more photosynthesis than respiration because they don’t have mitochondria. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year.
Answer:
1 .The leaves are only a small part of the plant and must produce enough energy-rich sugars to support all non-green parts like roots or flowers --TRUE.
2.Only when overall photosynthetic activity is greater than overall respiration activity of the whole plant can the plant accumulate biomass and grow--TRUE.
3.Sugar produced in photosynthesis must support the plant’s energy needs both day and night TRUE.
4. In trees that drop their leaves over the winter, some sugar produced in one year is stored in stems or roots and fuels the production of new leaves in the next year TRUE.
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria.
Explanation:
The statement that is FALSE is
Leaves perform more photosynthesis than respiration because they don’t have mitochondria and it is false because leaves contain both mitochondria and chloroplast.
The plants leaves have chloroplast, an organelles that house the chlorophyll which help its to photosynthesized. Plants also require ATP to carry out cellular activities and need oxygen to breakdown sugars produced from photosynthesis to produce ATP, because of this, they need mitochondria to achieve this and that is why they have mitochondria.
In the night, when there is no sunlight, plants perform respiration, they use oxygen to break the sugars they produced in order to produce ATP.

Answer:
A. emigration or increase in death rate
Explanation:
i just took the test and got it rigt lol
The two possible reasons for the change within frog population is emigration or increase in the death rate. Thus, the correct option is A.
What factors affect the population?The major factors which affect the population of a species are birth rate, death rate, and migration of the species.
Birth rate is the number of individuals born in a population in a particular time period. Birth rate adds more individuals to a population.
Death rate is the number of individuals die in a population in a particular time period. Death rate decreases the population number.
Immigration is the number of individuals which enter a population.
Emigration is the number of individuals which migrate out of a population.
Therefore, the correct option is A.

The area where an ocean meets land is called the ____ zone.
aphotic
photic
intertidal
benthic
Answer:
the area where ocean meets land is called the intertidal zone
The area where an ocean meets land is called the "intertidal" zone. Therefore, option (C) is correct.
What is intertidal zone?The intertidal zone, also known as the littoral zone, is the area of the shoreline that is exposed to air at low tide and submerged underwater at high tide. This zone is the boundary between the land and sea and is constantly affected by the ebb and flow of the tides. The intertidal zone is characterized by its unique physical and environmental conditions, such as the exposure to air and sunlight, the fluctuations in temperature and salinity, and the constant pounding of waves.
Due to these environmental conditions, the intertidal zone is home to a diverse range of plant and animal species that have adapted to the harsh and dynamic environment, such as barnacles, mussels, crabs, and seaweed. The intertidal zone is an important ecosystem that provides habitat, food, and breeding grounds for many marine species, and is also a popular area for recreation and scientific research.
