Answer: For building amino acids, proteins and nucleic acids.
Explanation:
Living cells requires nitrogen because they are major part of amino acids. They form the building block of protein and nucleic acids such as DNA which carry the genetic information and is passed from generations to generations. Plants and animal need nitrogen for growth and survival. The protein is use for building and repairing muscles and it is a necessity for growth.
Nitrogen is crucial for all cells as it forms the backbone of amino acids, proteins, and nucleic acids which perform essential roles in cell function.
All cells require nitrogen as an essential component for living organisms as it is an essential part of amino acids, proteins, and nucleic acids. Nitrogen forms the backbone of these molecules, which are fundamental structural and functional elements in cells. Amino acids are the building blocks of proteins, which perform many vital biological functions in cells. Similarly, nucleic acids, namely DNA and RNA, carry genetic information and are crucial in the synthesis of proteins. Without nitrogen, these molecules cannot exist and therefore, nitrogen is fundamental to all living organisms.

Answer:
The red balls here refers to the hydrogen and black balls refers to carbon.
Answer:
1.The Winogradsky section is a straightforward gadget for refined an enormous decent variety of microorganisms.The gadget is a segment of lake mud and water blended in with a carbon source, for example, paper which contains cellulose, darkened marshmallows or egg-shells which contains calcium carbonate.
2. carbon is important for providing cellulose for winogradsky column.
3.calcium sulphate in the form of gypsum or plaster of paris, craft or garden stores is used. green suphur bacterias and purple sulphur bacterias are formed after 2 to 6 weeks.
4.A hydrogen sulfide slope is created from the base to top in a Winogradsky section since sulfur-decreasing microorganisms like Desulfovibrio (microbes that utilizes maturation side-effects like Ethanol and Organic acids from Clostridium as a carbon source by means of anaerobic breath) produce a lot of H2S as a result of anaerobic breath. The H2S gradually diffuses upwards and is utilized by different life forms. The explanation the angle is higher at the base is on the grounds that anaerobic microscopic organisms like Desulfovibrio can't endure where O2 is available. The further down in a Winogradsky section the more anaerobic the earth. Along these lines, bigger measures of H2S are created at base of segment in light of the fact that there is a higher grouping of anaerobic microorganisms that produce H2S at the base as side-effect of their anaerobic breath process
5.Rather than utilizing water to photosynthesize, similar to plants and cyanobacteria, purple sulfur microscopic organisms use hydrogen sulfide as their decreasing operator, which is the reason they radiate sulfur as opposed to oxygen.
Explanation:
O Cell membranes with ester-linked fatty acids are found in both Archaea and Eukaryota but not in Bacteria.
The composition of cell walls is similar in Archaea and Eukaryota but not in Bacteria.
The single-celled prokaryotic cells of Archaea and Eukaryota are visually similar, but Bacteria is not.
traits identical to those of the parent plant
characteristics adaptive to the plant's environment
unique combinations of genetic material
Answer:
unique combinations of genetic material
Explanation:
Meiosis is one of the two types of cell division in which an organism produces daughter cells that are genetically different from the parent cell. Meiosis is the cell division which the cell uses to produce gametes (daughters cells).
The daughter cells are different genetically in the sense that they contain a different combination of chromosomes, which occurs in a process called CROSSING OVER. Therefore, a different but unique combination of the genetic material is actualized by MEIOSIS
