Answer:
A. 4 right handed coil:0, left- handed coil
Explanation:
According to MENDELION CROSS:
We will get NN, Nn,Nn,nn
NN, Nn, Nn are the 3 right handed coiling and nn is left handed coiling.
But in case of shell coiling in snails, maternal inheritance is applied in which offspring is decided only by phenotype.
Maternal traits: Here,female parent has right handed shell coiling. so, all the offsprings will have the same.
Hence, the phenotypic ratio will be:
4 Right handed coil: 0 Left handed coil
Water Cycle:
1. It is stored in the ground.
2. Evaporation, transportation, precipitation
3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.
4. It will usually end up in the same place, the ocean
5. Water levels rise, temperatures rise, CO2 in atmosphere increases
Carbon Cycle:
1. Carbon is important because it is one of the basic building blocks of life.
2. Trees, animals, grass, decomposition, combustion, fossil fuels
3. Carbon enters as photosynthesis.
4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.
6. By breathing in the oxygen from plants.
7. Two ways carbon return from animals into water is through cellular respiration and decomposition.
8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.
9. Deforestation reduces the capacity of forests to be carbon sinks.
Nitrogen Cycle:
1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.
2. It comes from lightning and is named nitrogen fixation.
3. Ammonification and then transitions into nitrification and then to assimilation.
Phosphorus Cycle:
1. It forms part of life sustaining molecules like DNA and RNA.
2. Phosphorus is never found in the atmosphere.
Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
The answer is c, people want to make a hybrid that is less likely to be diseased so that the plants wont die off
