Which of the following is NOT a statement from the cell theory?
O All cells come from pre-existing cells.
•All cells require water for survival.
•All living things are composed of cells.
•Cells are the basic unit of structure and function of living things.
Answer:
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.
Therefore, B is the answer.
"All living cells require water for survival" is NOT a statement from the cell theory.
All cells require water for survival is not a statement from the cell theory.
What is cell theory?The cell theory is a fundamental principle in biology that states that all living organisms are composed of one or more cells and that the cell is the basic unit of life. The theory was first proposed by German scientists Matthias Schleiden and Theodor Schwann in 1839, and later refined by Rudolf Virchow in 1855. The three main principles of the cell theory are:
All living organisms are composed of one or more cells.The cell is the basic unit of life and structure for all living organisms.All cells come from pre-existing cells through the process of cell division.The cell theory is considered one of the most important and enduring concepts in biology, and it forms the foundation for understanding the structure and function of cells and the organization of life on Earth.

C. C – U – A – G – G – A
D. T – C – G – A – A – G
Answer:
i think its B C D C and A
Explanation:
Hope this helps
The mRNA code determines which tRNA molecules are used. The purpose of this process is to synthesize protein. DNA contains the information used to make proteins. The presence of uracil (U) in codons makes difference between DNA and RNA. The correct options are A, D, C, C, and C respectively.
What is nucleic acid?Natural chemical substances called nucleic acids are the main information-transporting molecules in organisms.
They are particularly crucial in controlling protein synthesis. Deoxyribonucleic acid (DNA) and ribonucleic acid are the two primary types of nucleic acids (RNA).
That tRNA molecules are utilized is determined by the mRNA code. The creation of protein is the aim of this procedure.
The instructions needed to create proteins are found in DNA. Codons that contain uracil (U) distinguish between DNA and RNA as RNA possesses uracil in plane of thymine in DNA.
In the sequence given in the second image, the sequence of the mRNA will be C – U – A – G – G – A.
Thus, the correct options are A, D, C, C, and C respectively.

How do heredity and inheritance relate to the data presented In these charts
Your risk is greatly raised if any of these relatives have had breast or ovarian cancer. However, until many of these “secondary” relatives have the disease.
What is role of inheritance in breast cancer?A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.
Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.
Gene changes that are connected to breast cancer are typically acquired. Only the breast cancer cells experience acquired DNA alterations over time.
Therefore, Hereditary is Breast cancer and Inheritance is Getting Breast Cancer, basically it runs in the family inheriting.
