The gas exchange in plants takes place through stomata, and the process is called diffusion. ... The stomata cells are found on the dicotyledonous leaves, and they are arranged parallel in the case of monocotyledons.

The muscle that inserts on the acromion and scapular spine is the
daser333 [38]

The muscle that inserts on the acromion and scapular spine is the Trapezius.

The trapezius muscle inserts into the scapular spine acromion and posterior superior lateral clavicle. Contraction of its various parts thus allows the scapula to be lifted, suspended, stabilized, and rotated. inserted. The deltoid muscle inserts into the acromion process, the main muscle that raises and extends the arm.

In humans, the acromion process can be flat curved hooked, or convex depending on the shape. The intrinsic muscles of the scapula include the rotator cuff teres major subscapularis teres minor and infraspinatus. These muscles attach to the surface of the scapula and assist in the abduction and external and internal rotation of the glenohumeral joint.

What generally causes thymine dimers to form in a strand of dna, and why are thymine dimers a problem?.
valentina_108 [34]

Ultraviolet light can cause thymine dimers, potentially creating a mutation that could lead to cancer.

<h3>What  Causes Thymine Dimers ?</h3>

In a single POLYNUCLEOTIDE CHAIN a pair of THYMINE residues  that have become chemically bonded by the action of ULTRAVIOLET LIGHT. The lesion can inhibit DNA replication unless repaired.

Pyrimidine Dimers or thymine dimers  are usually covalent links between adjacent pyrimidine bases on the same strand of DNA.

Thymine dimers distorts the DNA shape and prevents the accurate copying of DNA, which causes mutations.

State two examples of situations where active transport occurs
Cloud [144]

When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).

Examples:

1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.

2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein

3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).

4.exocytosis - opposite of above
