Why is the ulna less movable than the radius?

Biology
1 answer:
vaieri [72.5K]3 years ago
6 0
Ulna is less moveable than radius because it has a hinge joint with the humerus in the process of olecranon. This joint only enable you to extend or flex the lower hand but not rotation. This cause it becomes more stable and less prone to subluxation. Radius joint with the metacarpophalangeal bones in the hand is also a loose one that allows rotation movement.

Complete a Punnett square for the cross-pollination of a female (TT) and a male (Tt). Write in the correct answers to complete t
Lerok [7]

Answer:

The correct answer is -

50% chances of Tt

50% chances of TT

Explanation:

In the given question it is given that there is a cross-pollination between a female (TT) and a male (Tt), which means female has two dominant copies of a trait in her genotype while the male is a heterozygous, the gametes of these genotypes will be:

gametes: T, t and T, T

then cross will be:

     T       T

T   TT    TT

t     Tt     Tt

Thus, the given result shows 1/2 TT and the rest 1/2 Tt by this Punnett square.

what acts as a connector to help convert the nucleotide sequence of mrna into the amino acid sequence of a polypeptide during tr
Vsevolod [243]

The organelle that acts as a connector to help convert the nucleotide sequence of mRNA into the amino acid sequence of a polypeptide during translation is the ribosome.

<h3>What is translation?</h3>

The translation is a biological process during which the genetic codes in mRNA are translated into their respective amino acids of a polypeptide during gene expression.

Prior to translation, genes are first transcribed from their nucleotide sequences of DNA to genetic codes in mRNA. The mRNA is then processed to remove non-coding sequences and some other treatments.

Thereafter, the mRNA binds to the ribosome in the cytoplasm, and in association with the tRNA, the genetic codes are translated to their respective amino acids one after the other. A peptide bond forms to connect successive amino acids to form the primary structure of a protein.

Thus, in order to convert the nucleotide sequence of mRNA into the amino acid sequence of a polypeptide during translation, the ribosome plays a central role and can be considered a connector.
