Sediment is the answer from the knowledge i have and from what i found
Answer:
The correct answer will be option-B.
Explanation:
Deoxyribose nucleic acid or DNA is the genetic material of the organism which is made up of nucleotide monomer. The structure of DNA is made up of two strands of nucleotides coiled in a helical structure thus providing a double-helical shape to the structure.
Each nucleotide of a strand is composed of a five-carbon sugar, phosphate group and nitrogenous bases. These molecules are arranged in anti-parallel fashion in DNA which provides the polarity to the DNA strand. One strand is read from the 5' to 3' direction whereas another form 3'to 5' direction.
Thus, Option-B is the correct answer.
The chemical reaction could be vary with the condition but the nuclear decay rate is constant, here the option A is the right option.
Question is incomplete. Complete question is as follows:
All cells have
A. a covering called a plasma membrane that surrounds the cell and controls what information and materials enter and leave it.
B. An internal fluid that gives shape to the cell and supports the other things within it
.
C. A central zone or nucleus that contains the cell's genes.
D. All of the above
Answer:
D. All of the above
Explanation:
- All cells have a protective covering called plasma membrane. It allows the entry and exit of selective materials. Some cells can have an additional layer outside it which is called cell wall. For example, plant cells.
- All cells have an internal fluid where the components of the cell float. It is called cytoplasm or protoplasm. It maintains the shape of the cell and also provides a structure to it.
- All cells also have a zone where the genetic material is present. The genetic material is ultimately responsible for keeping the cell alive and forming various proteins. In prokaryotic cell it is present just in a zone in cytoplasm. In eukaryotes it is present inside an organelle called nucleus.
- Hence, all the above things are present in each cell.
Answer:
Carbon is a primary component of all known life on Earth, representing approximately 45–50% of all dry biomass.[1] Carbon compounds occur naturally in great abundance on Earth. Complex biological molecules consist of carbon atoms bonded with other elements, especially oxygen and hydrogen and frequently also nitrogen, phosphorus, and sulfur
