Every cell of the organism has the same DNA sequence and same genes. However, not all genes are expressed in every single cell at the same time. Only those genes necessary for a specialised function of a specialised cell are expressed in the specialised cell. For example, skin cells have some different proteins than nerve cells. Genes responsible for those "skin proteins" are activated in skin cells and are turned off in nerve cells.
Answer:
Plants take in carbon dioxide from the environment for photosynthesis. Because trees are large, they need a lot of energy, which likely results in a lot of carbon dioxide being removed from the air. If they’re chopped down, there will be fewer trees to remove the extra carbon dioxide from the air.
Explanation:
answer from Plato
The survival of the 2 percent of the population is due to the presence of a gene obtained from other species. This gene must be responsible for developing resistance in the insects, against the insecticide that was used by the farmer. The gene got incorporated in only 2% of the insects and therefore, they survived and rest of them were susceptible to the insecticide and thus, died.
Answer:
<u><em>BRIEF EXPLANATION</em></u>
Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.
Explanation:
<em><u>MAIN ANSWER TO THE QUESTION.</u></em>
Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.
Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
<span>Calcium<span> is the element responsible for most of the material found in teeth.
Calcium plays a vital role in the formation and maintenance of healthy teeth and gums. Calcium makes the jawbones healthy and strong in order to hold the teeth in place.
Dairy foods such as cheese and yogurt, beans, cabbage and brown rice are good sources of calcium.</span></span>
