Answer:
The Oort Cloud is an expansive house of frozen bodies at the extreme edge of the solar system. It was named after the originally theorised astronomer Jan Oort. The Oort Cloud is approximately spherical and is known to be the centre of much of the long-term comets.

Explanation:
The phospholipid bilayer forms the outermost layer of cells called the plasma membrane of the cell.
The phospholipids are arranged in the bilayer with the globular head composed of glycerol and the phosphate on the outer side (hydrophilic) and the hydrophobic carbon chain in the inner side.
The hydrophobic molecule present in the layer provides a characteristic feature to the membrane that is known as selective permeability. The selective permeability allows the non-polar or uncharged molecule to pass through the membrane and not the large polar molecules.
This is because the non-polar molecules can interact with the hydrophobic portion (tails) which could allow the molecules to pass through the membrane but the polar molecules are repelled by the hydrophobic protein so require special channels.
Answer: Las células procariotas son aquellas que no tienen una membrana nuclear y su núcleo puede estar dispenso en el citoplasma de la célula, a diferencia de una célula eucariota, la cual tiene una membrana celular y una nuclear, la cuál puede ser vista con ayuda un microscopio.
Answer:
There are no chances for this couple to have a child with Tay-Sachs disease. 0% of the possibilities.
Explanation:
Tay-Sachs disease affects the nervous system and is potentially mortal. It is transmitted from parents to progeny. Tay-Sachs is caused by a defective gene in the 15 chromosome.
The child that recesives two coppies of this defective gene, one from the mother and one from the father, results sick. <u>But if only one of the parents transmits the gene, then the child will be a carrier.</u> This child won't be sick but will transmit the gene to his/her own progeny.
<u>Available data</u>:
- The allele for tay-sachs is a recessive allele, "t"
- Tim McGraw to determine is a carrier, Tt
- Tim´s wife is not a carrier, TT
<u>Cross:</u>
Parental) TT x Tt
Gametes) T T T t
Punnet square) T T
T TT TT
t Tt Tt
F1) Progeny genotype: 2/4= 1/2 normal, TT
2/4= 1/2 Carrier, Tt
0/4= 0 Sick, tt
What are the chances they could have a child with Tay-Sachs?
There are 0% of the possibilities that this family will get a sick child.
