I WILL GIVE BRAINLIEST!
Researchers wanted to do research because they thought normal cells spontaneously became cancerous cells.
What are Henrietta's cells?The first immortal human cells to be generated in culture were from Henrietta Lacks. They are also known as Henrietta's cells. They were crucial in the creation of the polio vaccine. In the early space flights, they went up to investigate what would happen to cells in weightlessness.
Her cells have since been employed in numerous significant scientific breakthroughs, such as cloning, gene mapping, and in vitro fertilization.

30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.

how are algae cells different from other cells
Answer:
In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.
Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.
Some characteristics of algae cells are:
• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.
By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.
• The cell wall is made up mainly of cellulose and glycoproteins.
• In the algae cells we can find different reserve substances produced by metabolism.
The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.
These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.
• They have structures of locomotion called flagella.
In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.
Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.

How energy from the sun is absorbed in earths atmosphere
Answer:
Explanation:
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system
Answer:
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.
help me fast lol this is a biology related question.
Answer:
A=5
B=9
C=3
D=4
Explanation:
3+2=A, so A must equal 5.
A+4=B, since we know A equals 5 then 5+4=B, therefore B must equal 9.
2+C=5, then use algebra to solve by subtracting 2 from both sides. C=3.
3+1=D, so D must equal 4.
