Eukaryotes have three nuclear RNA polymerases. The primary function of RNA polymerase II is transcription of protein coding genes
what are the function of RNA polymerase ?there are Three different types of RNA polymerases (RNAPs), which transcribe eukaryotic genes, such as RRNA genes are transcribed by RNA polymerase I.
mRNA, miRNA, snRNA, and snoRNA genes are mainly transcribed by RNA polymerase II, while tRNA and 5S rRNA genes are transcribed by RNA polymerase III.
short RNAs as well as the protein coding genes are both transcribed by RNA polymerase II.
A Separate type of RNA polymerases are present in chloroplasts and mitochondria, where they specifically transcribe the DNAs of those organelles.

Explanation:
Consider a neuron in which the Cl- concentration inside of the cell is 15 mM and outside of the cell is 140 mM. Once the ions flow and reach an equilibrium, approximately what will be the concentration of Cl- inside of the cell
Answer:
The correct answer is - negative.
Explanation:
Cl- ion is more concentrated outside of the cell, as it is given 140 and therefore it will try to move to the inside of the given cell as inside ion concentration is low.
At last, the diffusive force will be get to equilibrium due to an electrostatic force pulling Cl- ions back out of the cell. At this equilibrium point, Cl- ions will moved towards to the the neuron and cause the membrane potential to be more negative.
If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.
Answer:
C
Explanation:
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.
What is permeability?Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.
The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.
The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.
Therefore, option C. the less permeable roads cause rainwater to become runoff.

According to the theory of plate tectonics what drives the motion of the contenients
Answer:
The theory of plate tectonics is what brings together continental drift and seafloor spreading. Plates are made of lithosphere topped with oceanic and/or continental crust. The plates are moved around on Earth's surface by seafloor spreading. Convection in the mantle drives seafloor spreading. Oceanic crust is created at mid-ocean ridges. The crust moves outward from the ridge over time. The crust may eventually sink into the mantle and be destroyed. If a continent sits on a plate with a mid-ocean ridge, the continent will be pushed along.

A. contains the female egg cells,
B. contains the male gametophytes,
C. is usually much larger than the seed cone,
D. is the location of fertilization.
Answer:
The correct answer is B. The pollen cone contains the male gametophytes.
Explanation:
The cone is the reproductive organ of bare pollinators. Cones are not flowers but transformed stems or shoots without flower petals. In cones, male and female storages sit together in a shoulder-shaped arrangement on a short leg. Both males and females grow on pine. In male cones that are similar in most conifers, pollen matures, but the male cones wither quickly after the pollen has faded away.

A climate zone is an area that is defined by two main factors. What are they?
Temperature and weather
Precipitation and climate
Weather and climate
Temperature and precipitation
Answer:
Temperature and precipitation.
Explanation:
Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.
Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.

What is the purpose of using a Punnett square in studying genetics?
A. to determine the probability of an offspring to breed with another of the same phenotype
B. to determine the exact number of offspring having a particular genotype
C. to determine the probability of an offspring having a particular phenotype
D.to determine the probability of an offspring having a particular genotype
The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.
What is Punnett square?Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.
In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.
Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

Transplantation involves transferring from one site to another of cells, tissues or organs, often among people. An organ transplant (eg, kidney, liver, cardiac, lung, or pancreas) from a donor may rectify organ malfunction.
The immune system remains as a standard medical treatment the greatest barrier to transplantation. An effective and intricate mechanism has been evolved in the immune system to fight off invading invaders. These systems also contribute to the refusal of the transplanted bodies that are recognized by the immune system of the receiver as foreign.
