A Chlorella cell viewed through a microscope is 0.00005 m wide when the magnification is 2000.
juin [17]

Answer:

0.0025micrometer.

Explanation:

To calculate the actual size of the image, the formula to be used is

Actual size=Image size÷magnification.

The image size is 0.00005 wide

Magnification is 2000

First, convert the image size to micrometer.

=0.00005 × 1000000

50micrometers.

Actual size= 50÷2000

Actual size = 0.0025

nignag [31]

Answer:

Hip joint

Explanation:

Coxofemoral joint or hip joint. This joint joins the femoral head with the cotyloid cavity of the iliac or coxal bone. Together with the sacrum and the coccyx, both iliacs form a bony waist called the pelvis.

Joint capsule: It is a fibrous cuff that is inserted into the bone perimeter of the cotyloid cavity and the neck of the femur. The capsule is upholstered by a synovial.

Iliofemoral or Bertín: It is inserted in the anterior inferior iliac spine. It is directed downwards through two upper or iliopretrochanteric F.s: it is inserted in front of the facsimiles: F. lower trochanter major or iliopretrochanteric: it is inserted in front of the smaller trochanter.

Pubofemoral: It is inserted into iliopectine eminence, it ends in retrocantineal depression.

Ischio-femoral: It is located on the back of the joint. It originates in the subcotiloid canal and in the periarticular impeller. It ends on the inner side of the greater trochanter (in front of the digital pit).

- Round ligament

- Capsuar ligament.

Round ligament: Measures 3 cm long. It is intraarticular. It extends from the femoral head to the ischiopubial recess of the iliac. It has three fascicles Anterior ends at the anterior end of the recess. Medium ends in the transverse ligament of the Posterior acetabulum passes under the transverse ligament and joins the bone outside the notch.

The round ligament has an artery inside it that supplies the head of the femur. This artery is the branch of the obturator artery. The bottom of the acetabulum, head of the thorn femurllion of the ischium, iliac spine is removed.

How might you alter a trna so that it inserts an alanine into a polypeptide for which a lysine is coded?
castortr0y [4]
TRNA stands for transfer-RNA which is used in the process of protein synthesis or translation. tRNA is a unique clover leaf like structure that has 4 arms- amino acid acceptor site (acceptor arm), D loop, T psi C loop and anticodon loop. It also has a small variable loop. The anticodon loop consists of a sequence of 3 bases that is complementary to the 3 bases present of mRNA to be translated. A tRNA for alanine will have an anticodon for alanine while a tRNA for lysine will have an anticodon for lysine. For a tRNA to insert an alanine in place of lysine in a forming peptide, the anticodon and the amino acid acceptor site should be altered so that it accepts lysine in place of alanine and add it to the growing polypeptide.
