Answer:
hope it helped
Explanation:
Each unit of inheritance can have alternate states (alleles) that segregate at meiosis, with each gamete receiving only one allele (the principle of segregation, Mendel's first law); different alleles assort independently in the gametes (the principle of independent assortment, Mendel's second law).
B. Transform boundaries are when the land rubs back and forth against each other causing earthquakes
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.
Skin cells, divide in a continuous manner that makes new skin cells to replace the skin cells we lost. Cells regulate their division by cyclins. Some cells divide faster when it supposed to stop dividing and this will lead to cancer disease.
<u>Explanation:</u>
The process of cell division occurs for many reasons. A single cell is divided into two which in turn they will be divided into four and so on. This corresponds to the process of cell division and cell reproduction. Cell division is an unique characteristics in human beings. Interactions between signaling proteins produces checkpoints in the cell cycle to ensure that cells do not divide at improper times.
A protein named Cyclins plays a major role in the determination and the regulation of the cell division process. The division that occurs in the cell can be regulated by the this protein type. They acts as a switch for controlling the cell division process. They will signal the cells when to divide and when to stop. When any cell continues to divided even after it is signaled to stop they may lead to a disease called cancer. These are different form the normal cells because they will be having their own growth factors that controls their growth and they will lose the normal controls on the cell cycle.
The sodium levels increase inside the cell during action potential. Opposite to resting state, depolarization is the shift of electrical charge resulting in positive charge inside the cell. Depolarization is the start of cell-to-cell communication and other necessary physiological functions of an organism.
