Answer and Explanation:
<u>Cruza</u>: persona sana sin mutaciones con persona portadora
El parental sano aporta alelos normales del gen a la descendencia
El parental portador aporta un alelo normal y un alelo alterado. Tiene el 50% de probabilidad de transmitir la enfermedad a la progenie.
Parental) AA x Aa
Gametas) A A A a
Cuadro de Punnet) A A
A AA AA
a Aa Aa
F1) 2/4 = 1/2 = 50% de la progenie seran individuos sanos AA
2/4 = 1/2 = 50% de la progenie seran individuos portadores Aa
Como uno de los progenitores es portador, cada individuo tiene un 50% de posibilidades heredar el gen alterado.
Answer:
- Both organelles present their genetic material.
- Both organelles divide by binary fission
- Both organelles present a double membrane, the internal one looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one.
- In the internal membrane are placed the energy centers, just as it occurs in bacterias membrane.
- The sizes of the organelles are similar to the size of some procaryotes
Explanation:
The endosymbiotic theory essentially states that some organules of the eukaryotic cells, such as mitochondria and chloroplasts, were once free-living bacteria. Probably, these organisms must have been phagocytized but not digested by another cell. These bacteria were able to adapt to their host, establishing a bond of dependence among each other.
Both organelles have many similarities with other free-living bacteria. For this reason, the theory states that chloroplasts derivate from cyanobacteria (because they both absorb sunlight, store the energy in ATP, and produce organic molecules) and that mitochondria derivate from rickettsias (because they produce ATP in the same way, by using the Krebs Cycle and Oxidative Phosphorylation).
This theory is supported by a few characteristics of the chloroplasts and mitochondria that suggest that they once were free cells. For example,
- Both organelles present their genetic material. This DNI is independent of the cells´ DNA, is bi-catenary and circular, identical to the bacterial DNA, and very different from the one of the eukaryotic cells.
- Both organelles divide by binary fission, not by mitosis, and can synthesize their ribosomes and organelles.
- Both organelles present a double membrane, a characteristic that reinforces the idea of being phagocyted. The internal membrane looks identical to the bacterial membrane, while the external membrane looks like the eukaryotic one.
- In fact, in this internal membrane are placed the energy centers, just as it occurs in bacterias membrane.
- Finally, the sizes of the organelles are similar to the size of some procaryotes
This genus is promptly present as a piece of the ordinary microbiota on the vast majority's skin, so it could without much of a stretch enter wounds. Staphylococci are Gram-positive cocci around 0.5 – 1.0 μm in width. They develop in groups, sets and sporadically in short chains. The bunches emerge in light of the fact that staphylococci partition into two planes. The arrangement of the cocci recognizes micrococci and staphylococci from streptococci, which more often than not develop in chains.
Answer:
Body functions, reflex development, and skin details
Explanation:
The second trimester marks the period between the thirteenth to the twenty-sixth week. During this period of fetal development, the fetus begins reflex development such as sucking and swallowing. He is also now able to respond to stimuli.
Body functions are also developing at this stage. The baby can now kick, turn, and move his body. The brains are developing, the hairs and fingernails are also beginning to develop.
Skin details are also developed at this stage. For example, the vernix caseosa is produced to protect the skin of the fetus.
