Answer:
Pyramidal decussation is at the junction of medulla and spinal cord.
Explanation:
Pyramidal decussation may be defined as the the fibers that cross the corticospinal tract from one side to the junction and the other side to the central nervous system.
Pyramidal decussation is the point at the junction between spinal cord and medulla. The motor fibers crosses the midline from the medullary pyramids.
Answer:
cada célula tendrá dos núcleos
Explanation:
El complejo o aparato de Golgi es un organela compuesta por un grupo de membranas apliladas una sobre la otra formando una serie de sacos aplanados. El complejo de Golgi tiene diversas funciones: maduración, modificación (glicosilación), transporte y secreción de proteínas. En células vegetales, el aparato de Golgi sintetiza vesículas que forman parte del tabique telofásico el cual sirve para dividir el citoplasma de células vegetales durante la citocinesis. En consecuencia, si se eliminara esta organela, el tabique telofásico no se formaría y las células resultantes estarán compuestas por dos núcleos.
Answer: The citric acid cycle, also known as the Krebs cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions in the cell that breaks down food molecules into carbon dioxide, water, and energy. In plants and animals (eukaryotes), these reactions take place in the matrix of the mitochondria of the cell as part of cellular respiration.
Explanation:
Answer:
10%
Explanation:
The distance between the given two loci is 20 mu. This means that the recombination frequency between these two loci is 20% and the heterozygote will form 20% recombinant gametes and rest 80% parental type gametes. Therefore, the heterozygous woman AB/ab will form a total of 20% recombinant gametes. The proportion of each recombinant gamete will be 20/2= 10%.
Gametes formed by the woman= 10% Ab, 10% aB, 40% AB, and 40% ab
Gametes formed by the man= All ab (since the man is homozygous for both loci).
Therefore, proportion of Ab/ab genotype= 10% Ab (female gamete) x ab (male gamete)= 10% Ab/ab
Answer:
The tasting allele is dominant.
Explanation:
- The law of dominance states that the dominant allele will always express itself in homozygous or heterozygous conditions.
- While, the recessive allele Can express itself only in Homozygous recessive condition.
- The phenotypic ratio in case of monohybrid cross is 3:1 where i.e , about 3 out of every four offspring tends to express the dominant trait.
- According to the given statistics,80% of the population can taste PTC and 20 % cannot.
- Thus The tasting allele is a dominant allele.
