4. When plates slide against each other as seen on the San Andreas fault,many__________ are known to occur.
Zina [86]

Plate boundary is the type of boundary which occurs when plates slide against each other as seen on the San Andreas fault in which many earthquakes are known to occur.

<h3>What is an Earthquake?</h3>

This is characterized by the ground shaking as a result of movement in the Earth crust.

Plate boundary is responsible for Earthquakes on San Andreas fault thereby making it the most appropriate choice.

Compare and contrast p-dependent and p-independent termination of transcription in prokaryotes.
iVinArrow [24]
Compare and contrast two mechanisms for transcriptional termination in bacteria.

(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid

(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination

hope this help

1. Name three muscles in the upper body, and describe their location. (anterior, posterior, etc.)
Kazeer [188]
1) - The coracobrachialis and pectoralis major muscles connect the humerus anteriorly to the scapula and ribs, flexing and adducting the arm toward the front of the body when you reach forward to grab an object.
- On the posterior side of the arm the teres major and latissimus dorsi extend and adduct the arm towards the scapula and vertebra when you pull an object down off of a shelf above your head.
- The deltoid and supraspinatus muscles run superiorly between the scapula and humerus to abduct as well as flex and extend the arm.

These muscles allow us to raise our arm in the air or swing the arm as in throwing a ball underhand.

2) cariac muscle makes up the heart, its involuntary, striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.

3) Smooth muscles are composed of elongated, spindle shaped cells and are commonly involved in involuntary motions. Skeletal muscles allow movement by being attached to bones in the body.  Skeletal muscles control voluntary movements which can be consciously controlled.

4) Calcium is a crucial part of muscle contraction. The ionic element is released from muscles during contraction and relaxation. The release of calcium helps propagate the muscle contraction and relaxation stages. An adenosine triphosphate molecule stores energy that is released and used by energy-consuming reactions, such as muscle contraction, transmission of nerve impulses and formation of other molecules. ATP is found in cells and is made from the breakdown of food. It is composed of oxygen, hydrogen, phosphorus and carbon atoms. The energy in an ATP molecule is locked within phosphate bonds, which hold its phosphate groups together.

5) The muscle would neither contract nor relax if ATP was'nt there. It would stay in the same state because ATP is required for contraction as well relaxation of muscle. That is why dead bodies become very stiff.
