Graduating from high school this year makes me feel a bit sad. Biology was such a fun but crazy class.
Enough of my sentiments; I'm here to help, :-).
This answer is dependent upon what ecosystem you choose your project over.
So, abiotic factors are nonliving things in an ecosystem. Biotic factors are living organisms and anything alive.
For instance, if you choose a pond for your ecosystem then the water, soil, maybe trash would be abiotic factors. Some could argue there is living material within the water and soil but those abiotic factors are not alive. I mean water is not alive but it could be a home to biotic factors like microorganisms such as protozoans and worms. The grass and trees and animals around a pond would be biotic factors.
Hope you get the idea. if there's any questions then leave a comment and I'll help. Good luck!
Answer:
A. Cell
B. Organ
C. Tissue
Explanation:
cell: The smallest unit of life capable of independent reproduction. Generally contains nucleic acid, cytoplasm, a cell membrane, and many other proteins and structures.
organ: A structure made of different tissues that work together to perform physiological functions.
Tissues: A group of similar cells with the same origin that work together to perform the same function.
The discoverers of DNA were not
James D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”
Give us Choices, but I’m guessing it’s limiting factor
