Answer:
Atmospheric carbon dioxide (from animals)
Explanation:
The carbon atoms in glucose come from the atmospheric carbon dioxide molecules that are taken in by plants for photosynthesis.

Answer:
The X-shaped structure is made of strands of DNA.
Explanation:
The chromosomes are thread-like structures located in the nucleus of each cell in the body. In a human cell, there are 23 pairs of chromosomes found in the nucleus. Each chromosome is made up of strands of DNA tightly coiled many times around proteins called histones which gives support to its structure.
The chromosomes are X-shaped and are observed only in a cell undergoing division by mitosis or meiosis. Each of these X-shaped chromosomes consists of two identical sister chromatids. The sister chromatids are connected to each other by a region of the chromosome called the centromere. The centromere are located around the depression point of the chromosome which divides the sister chromatids into two regions: long arm called the q arm and a shorter arm called the p arm. During mitosis, spindle fibers attach to this region, and they eventually pull the sister chromatids apart to form two separate chromosomes, one for each daughter cell.

Answer: ribosomal RNA (rRNA)-aids translation
messenger RNA (mRNA)-gives message
tRNA-transfers amino acids
Explanation:RNA is ribonucleic acid and its of three main types in human with specific function.
tRNA- Transfer ribonucleic acid is located in the cytoplasm and helps in the transfer of amino acid to the appropriate base sequence/nuclotide bases during translation
mRNA - messanger RNA carried genetic information form the nucleus the cell to the ribosome.
It helps read and transform the bases into a protein.
rRNA-ribosomal RNA is located in the ribosme and aids transcriotion of nucleotide bases into protein.
Diffusion happens when there is a difference in concentration. So for water to diffuse out of the cell, the concentration of water has to be lower outside the cell, than inside the cell.
