Answer:

In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:

1.BRCA2  

2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2  cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)  

3.BRCA1  

The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.

In an energy pyramid, the amount of energy at the producer level is 475,650 kilocalories. the pyramid has four trophic levels, i
AURORKA [14]

The energy available for the second-level consumers is <u>4756.5 </u>kilocalories.

A trophic level is a  position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.

The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.

Calculation:

Producers (475650 kilocalories) —>  Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).

So, the energy available for second-level consumers is 4756.5 kilocalories.

Describe a human activity that disrupts the carbon cycle and the consequences of that disruption
OlgaM077 [116]
Hey there!

The Carbon Cycle refers to photosynthesis, during which plants take the CO2 we make and release it back into the atmosphere. One way this process could be interrupted is if a company cuts down a lot of trees for land, destroying many of the plants that keep the Carbon Cycle moving.

Hope this helped, good luck :)
