Answer:
Sediments compact and cement together.
Explanation:
Generally, rocks are of three main types viz: Igneous, sedimentary and metarmophic rocks. Based on the question, the sedimentary rocks are that group of rocks formed by the coming together of sediments.
Sedimentary rocks can be formed in the following steps;
1. Rocks that have existed before undergoes weathering i.e. are broken down into smaller particles called sediments.
2. These sediments are then transported by currents e.g water
3. Deposited sediments accumulate and gathered round.
4. The accumulated sediments become compacted i.e. squashed and cemented i.e. stick together to form the sedimentary rock, in a process collectively lithification.
Hence, compaction and cementation (lithification) are the next steps in the process of sedimentary rocks formation after deposition.

Answer: chromatin
Explanation:
What is uncoiled, stringy DNA called? It is called chromatin. How many pieces of chromatin does a human diploid cell have? Human diploid cells have 46 pieces of chromatin.
Answer;
D.Carbon-based macromolecules are found in all life forms.
Explanation;
-Most molecules that make up living things are based on carbon atoms. The structure of a carbon atom allows it to form up to four covalent bonds. It can bond to other carbons or to different atoms.
-All organisms are made of four types of carbon-based molecules; carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are molecules made of carbon, hydrogen, and oxygen. Sugars and starches are both types of carbohydrates. These carbohydrates can be broken down to produce energy in cells. Some carbohydrates are part of cell structure in plants.
-Lipids are molecules that include fats, oils, and cholesterol. Lipids are nonpolar, so they do not dissolve in water. Like carbohydrates, most lipids are made of carbon, oxygen, and hydrogen atoms. Some lipids are broken down and used as energy in cells.
-Proteins are the most varied of the carbon-based molecules in organisms. There are many different types of proteins. They are involved in many different body functions including movement, eyesight, and digestion.
B. the warmer air contains more water vapor per unit of volume
