The coracobrachialis
is a elongated, skinny muscle that acts completely on the shoulder joint. Its
main functions are to draw the arm forward and to pull the arm toward the
midline of the body. The muscle originates from the coracoid process, a small
part of the scapula. It inserts midway along the inside of the humerus, a long
bone in the upper arm.
Answer:
Watson & Crick
Explanation:
They received the Nobel prize for science for their discovery in 1962. Their capacity to be able to represent DNA double helix in 3D was made possible by advancements in the model building- a science that allows three-dimensional structures to be modeled based upon known molecular distances and bond angles.
Options for the question have not been give. They are as follows:
A. P site
B. A site
C. E site
D. directly to the cytosol
E. exit tunnel
Answer:
C. E site
Explanation:
Translation is the process by which mRNA is converted into polypeptide chain. Translation machinery has three binding slots for tRNA : A, P and E. Any incoming tRNA encounters A, P and E site in that order.
When a new tRNA (#1) carrying the next amino acid (here, lysine) comes, it enters the A site. Peptide bond is formed between lysine and the already existing amino acid on the growing polypeptide chain on the preceding tRNA (#2). Once lysine is added to the polypeptide chain, the entire chain moves to tRNA #1 which makes tRNA #2 empty. Meanwhile, the machinery moves forward. As a result, tRNA #1 slides to P site and tRNA #2 slides to E site. The A site is empty now and can receive another tRNA.
Human cells that have completed telophase i will each contain 233 chromosmes, which will be in a(n) replicated form.
What is telophase and why it is important?
The end of mitosis is known as telophase. Each chromosome has moved to one of the poles at this point. The nuclear membrane that surrounds these chromosomes forms at each of the cell's poles while the cell is compressed in the middle (in mammals) or divided by a cell plate (for plants).
Telophase is followed by Cytokinesis, or the division of the cytoplasm into two daughter cytoplasm cells. The daughter cells that result from this process have identical genetic composition.

Answer:
Absorption of Water and Electrolytes. ... Sodium is absorbed from the intestinal lumen by several mechanisms, most prominently by cotransport with glucose and amino acids, and by Na+/H+ exchange, both of which move sodium from the lumen into the enterocyte.
Large Intestine
Water is always absorbed in the alimentary tract through passive osmosis via a mostly paracellular route between enterocyte tight junctions. Consequently, water absorption is primarily actuated by active absorption of osmotic electrolytes, especially sodium.
Absorption of Water and Electrolytes. The small intestine must absorb massive quantities of water. ... Net movement of water across cell membranes always occurs by osmosis, and the fundamental concept needed to understand absorption in the small gut is that there is a tight coupling between water and solute absorption.
A majority of water's absorption into the bloodstream occurs after water passes through the stomach and on to the small intestine. The small intestine, at around 20 feet long, efficiently absorbs water into the cell membrane and bloodstream. ... Once absorbed into the body, water aids a number of vital functions.
Hope this helps
