When the core of a nuclear reactor completely melts, it is known as a (n) _______.
A) Downstream
B) Meltdown
C) Turbine
D) Ethanol
E) Passive solar cooling
F) Utility
G) First Law of Energy
H) Refinery
I) Isotopes
J) Second Law of Energy
Answer:
B
Explanation:
A core meltdown accident occurs when the heat generated by a nuclear reactor exceeds the heat removed by the cooling systems to the point where at least one nuclear fuel element exceeds its melting point. This differs from a fuel element failure, which is not caused by high temperatures.

Borh worker and queen bee are developed from fruel eggs .but why workers bee can not reproduce like that of queen bee?
Answer:
------->
Explanation: Why worker egg-laying occurs in honey bee colonies. Usually, colony behavior, egg-laying, and ovary development in worker honey bees are prevented by queen pheromones and open brood pheromones. However, in the absence of these regulating pheromones, workers may develop ovaries that will enable them to lay their own eggs.

Identity the stomata components. record your answer under "" slide 2"" on your lab report
Stomata are involved in gas interchange and transpiration. The components of stomata are the pore, the guard cells, subsidiary cells, and the stomatic chamber.
What are stomata?On the leafs' surfaces, there are small pores that regulate gas interchange and transpiration. These openings are the Stomata.
Gas interchange ⇒ CO₂ gets into the plant, and O₂ leaves it Transpiration process ⇒ water expel
Stomata opening and closure depend on water and CO₂ concentration inside the plant.
These pores are surrounded by two kidney-shaped cells called Guard cells. They expand or contract according to the plants' needs, causing the stomata to open or close.
The space left between these guard cells is the pore.
Other cells that vary in shape and number are surrounding the guard cells and are functionally associated with them. These are the subsidiary cells.
The pore is connected to a wide intercellular space inside the leaves called the stomatic chamber.
According to this framework, the components of the stomata are,

Research has suggested that the burning of fossil fuel has had to change in the carbon cycle causing an increase in carbon store in the atmosphere. Determine how much less carbon would need to be realesed by burning fossil fuels in order for the amount of carbon stored in the atmosphere to not increase.
The carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.
What are fossil fuels?Fossil fuels (e.g. coal) are different types of fuels obtained from fossils, which release carbon dioxide into the atmosphere when they are burned.
Carbon dioxide (CO2) is a gas that has a greenhouse effect and thus can produce climate warming.
In conclusion, the carbon that would need to be released by burning fossil fuels should be lesser than the generation of oxygen in order for the amount of carbon not to increase.

What shuffles genes and increases genetic variation in gametes during meiosis, when these homologous pairs are paired up ?
Meiosis is referred to as reduction division as it divides the chromosome number in half. Crossing over or recombination is the main reason of shuffled genes and increased genetic variation in gametes in meiotic cell division as the homologous pairs are paired up during prophase.
What is crossing over?Crossing over is referred to as the exchange of genes of DNA between paired homologous chromosomes. It actually occurs during the development of egg and sperm cells i.e., during meiosis.
It is an enzyme-mediated step, in which the exchange of genetic material takes place between non-sister chromatids of homologous chromosomes.
It actually occurs at the pachytene stage of prophase I of meiosis cell division.
Thus, it can be concluded that the crossing over is the main reason of shuffled genes and increased genetic variation.
