Answer;
-Cell theory
The most accepted theory regarding the make-up of living things is the cell theory.
Explanation;
-Cell theory is a theory that includes one or both of the statements that the cell is the fundamental structural and functional unit of living matter and that the organism is composed of autonomous cells with its properties being the sum of those of its cells.
-According to cell theory; All living beings are made up of cells. Cell is the most basic unit of life. All cells must come from pre-existing cells.
-Cells are autonomous, in that they can acquire and use nutrients to obtain energy and they can reproduce. Simple organisms like bacteria are unicellular and composed of a single cell.
thunderstorm.
c.
hurricane.
b.
tornado.
d.
flash flood.
The correct answer is Flash flood.
A sudden flood that is a result of heavy rain is called a flash flood. It lies in the low lying areas. The rain might sometimes accompany thunderstorm, hurricane, or snowfield. The difference between a flash flood and normal flood is that it lasts less than till 6 hours. In this case a high place can be used as a temporary shelter and once the flash flood is gone, anyone can shift to his or her normal routine.
b. Carbohydrates will dissolve in water but not lipids.
c. Carbohydrates contain hydrogen, carbon, and oxygen and lipids do not.
d. Lipids contain hydrogen, carbon, and oxygen and carbohydrates do not.
Answer:
B. Carbohydrates will dissolve in water but not lipids
Explanation:
Both carbohydrates and lipids have oxygen, carbon and hydrogen molecules in their compositions.
However, the difference is that carbohydrates are polar and lipids are nonpolar. Nonpolar substances can only be dissolved in nonpolar solvents and so they are insoluble in water (which is polar). Compounds with this feature are called hydrophobic.
Answer:
Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
Explanation:
B: pair of nonsister chromatids facing opposite poles
C: pair of tetrads facing opposite poles
C. making alcohol
D. killing bacteria.
Answer: Option B
Explanation: The fungi are the decomposers of the ecosystem. It helps in cleaning of the environment by converting the dead and decaying organic matter into nutrients in the soil.
This is how the fungi recycle the nutrients back into the soil so that the plants can take the nutrients from the cycle.
Fungi play a vital role in ecosystems as decomposers by breaking down dead organisms and releasing nutrients back into the environment.
An important role of fungi in an ecosystem is breaking down dead organisms. This process is known as decomposition. Fungi are heterotrophic organisms, meaning they cannot manufacture their own food through photosynthesis like plants do. Instead, they rely on the absorption of organic matter, often from dead or decaying organisms, to sustain themselves. By breaking down this organic material, fungi release nutrients back into the ecosystem, aiding the growth of new life.
