Answer:

Stars produce energy from nuclear reactions, primarily the fusion of hydrogen to form helium. These and other processes in stars have lead to the formation of all the other elements.

HYDROGEN

Energies produce a star centre or core where pressure are enormous and temperatures reach 27 million Fahrenheit Miss causes nuclear fusion Atoms of hydrogen are rip apart and fuse to form helium these reactions release of a vast amount of energy which makes the star shine

The container below is separated into two sections by a semi-permeable membrane. Sugar molecules are too large to move across th
ELEN [110]

Answer:

b or c

Explanation:

The water will move to the section with lower water concentration until it is balanced, however, I don't know which section has the sugar and which has the water. a is wrong because the membrane is semi-permeable, so water can go through, and d is wrong because it is provided the sugar cannot move across the membrane. Hope this helps some :)

Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during t
balandron [24]

Answer:

DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments

Explanation:

Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., <em>BamH</em>), or blunt ends, where the resulting strands are of the same length (e.g., <em>HaeIII</em>). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.

Interfacial adhesion and surface bioactivity of anodized titanium modified with SiON and SiONP surface coatings, The statement is correct.

<h3>what is adhesion ?</h3>

Adhesion is a type of attraction between two dissimilar phases, the theory of adhesion can be up two types mechanical interlocking and physical and chemical bonding and it is a combination of three methods.

Mechanical interlocking means when two dissimilar phases interact with  one another by mechanical forces, requires a rough surface where the other material can enter.

Physical bonding includes van der Waals forces and the strength  is rather weak and unable to contribute that much bonding strength.

Chemical bonding consist of covalent, ionic and metallic bonding which are more stronger than physical bonds and are responsible for cohesive forces.

chemical bonding between two dissimilar materials is  more complicated due to the presence of few available bonding sites.
