A fertilized egg is called a zygote until it divides into 16 cells, forming a ball-shaped structure called a morula. The events during the zygote stage involve the integration of both parents' DNA into the cell nucleus and the beginning of rapid cell division, or cleavage.
Answer:
Codominant- traits don’t have a clear dominant or recessive
incomplete dominance- the heterozygous condition shows a “blending” or a “middle” condition
Explanation:
In codominance, the traits are expressed equally in the phenotype thus they don't have a clear dominant or recessive state. For example the ABO blood group alleles. The alleles A and B are codominant each being expressed equally.
In incomplete dominance the traits show intermediate expression where one allele expresses itself more strongly than the other. An example in man is seen in the inheritance of the disease sickle cell anaemia. Heterozygote who carry the sickle cell gene are said to have sickle cell trait and as such the carrier allele (HBa) has a stronger influence on the phenotype than the dominant alle (HBs).
Answer:
I Think this answer will help
Explanation:
Soda ash/sodium hydroxide injection
This treatment method is used if water is acidic (low pH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
Ribosomes.
Proteins are used for cellular repairing and chemical processes. Ribosomes are one of the most important organelles in the cell, mostly part of the rough endoplasmic reticulum. It manufactures enzymes such as proteins which will be utilized by many organelles in the cell. Microtubules are one, responsible for the framework and acts as a skeleton of the cell –cytoskeleton needs proteins, also cytoplasm and other organelles of the cell. For a prokaryote or a eukaryote cell to survive, they need protein.<span> Fundamentally, the cell would cease to function and possibly die</span>
