Obsidian is an extrusive rock that is formed when magma from underneath the Earth's crust breaches and becomes lava. Once the lava starts cooling, it solidifies and elements are frozen, giving the rock its glassy appearance.

Which term describes cycles of hot and cold temperatures which expand and contract rock in combination with constant wind and wa
marishachu [46]

The correct answer is option C, that is, physical weathering.  

The weathering resulting due to the influences of changing temperatures on a rock, making the rock to split apart is known as physical weathering. There are two main kinds of physical weathering, that is, exfoliation and freeze-thaw.  

Physical weathering takes place mainly in the locations, where few plants grow and little formation of soil occurs, like hot deserts and mountain regions. It takes place either via repeated freezing and melting of water or via contraction and expansion of the rocks surface layer, which is baked by the sun.

Choose the law that BEST explains the example:
german

Answer:

3rd law

Explanation:

First law of Newtons :

 Newton's First Law states that, unless an external force acts on it, an object will remain in a straight line in rest or uniform motion.  

The second law of Newtons :

The second law states that an object's acceleration depends on two variables-the net force that acts on the object and the object's mass.

The change in the linear momentum of the object is equal to the force.

Third law of Newtons :

This law states that every action has its reaction with the same magnitude but in the opposite direction.

When we push the wall , then the wall does not move because the wall is fixed but we skid opposite to the direction of applied force because wall offers an opposite force on our body.

Therefore the answer is "third law".

Penicillin-binding protein 2a, encoded by the medA gene, isn’t affected by beta-lactam antibiotics.
Flauer [41]

Answer:

The correct answer is - false.

Explanation:

Penicillin-binding protein 2a or PBPs are protein produced by bacteria that binds with the β-lactam antibiotics such as penicillin. They play role in the cell wall synthesis of bacteria by producing peptidoglycan by catalyzing the reaction.

β-Lactam antibiotics bind with the PBPs and cause the disruption to peptidoglycan cross-linking in the biosynthesis of the cell wall and ultimately lysis of bacteria takes place and cell death.

Hepatocyte growth factor aff ects satellite cell activation and diff erentiation in regenerating skeletal muscle
vichka [17]

Hepatocyte growth factor (HGF) is the only known growth factor that activates quiescent satellite cells in skeletal muscle.

Hepatocyte growth factor regulates cell growth, cell motility, and morphogenesis by activating a tyrosine kinase signaling cascade after binding to the proto-oncogenic c-Met receptor. Hepatocyte growth factor is secreted by mesenchymal cells and acts as a multi-functional cytokine on cells of mainly epithelial origin.

HGF, produced by some cancer cells, stimulates c-Met, through activation of the autocrine signaling system. Hepatocyte growth factor (HGF) is a paracrine hormone that plays an important role in epithelial-mesenchymal transition. HGF secreted by mesenchymal cells affects many properties of epithelial cells, such as proliferation, motility, and morphology.
