"How does carbon enter water?" : Carbon<span> dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the </span>carbon<span> dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the </span>carbon<span> into organic matter.
"How does aquatic plants get carbon" : </span><span>The only difference between photosynthesis in </span>aquatic<span> and land </span>plants<span> is where in their environments they </span>get<span> these nutrients. Land </span>plants get<span> water from the ground through their extensive root system, </span>carbon<span> dioxide from the air through their stomata (tiny holes in a </span>plant's<span> leaves), and energy from the sun.</span>
Answer: protein structure
Explanation:
In Sickle-cell anemia, the gene sequence of hemoglobin is changed in its sixth position due to the substitution of glutamate with valine.
So, since glutamate, an amino acid soluble in water due to its hydrophilic side chain is substituted with valine, an amino acid that has a hydrophobic side chain insoluble in water or bloodstream; the resulting hemoglobin protein is altered in structure (sickle shaped) and unable to bind and transport oxygen efficiently to the various body parts.
Answer:
The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.
The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.
Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
