Answer: Option (c) is the correct answer.

Explanation:

When there is recombination of atoms to form newer molecules then it is called a chemical change.

For example, A-B + C-D \rightarrow A-C + B-D is a chemical change.

Tarnishing of a silver coin is a chemical change which occurs when silver reacts with moisture in the air as a result silver loses its luster.

Thus, we can conclude that out of the given options tarnishing of a silver coin is an example of recombination of atoms to form newer molecules.

The correct option is C.
The recombination of atoms to form newer molecules is called chemical change. Tarnishing is a chemical change that occur when a metal lose luster as a result of exposure to moisture and water which results in a thing layer of corrosion which forms over the metal.<span />

6.(02.01 MC)
Luda [366]

Answer:

Attractive forces between particles.

Explanation:

Solids keep its shape and volume because of strong attractive forces between the particles.

Other options are incorrect:

Because there is no space between solid particles.

The shape of solid does not depend upon type of particles present.

The shape and volume of solids not depend upon the volume and shape of container.

Properties of solids:

Solids have definite volume and shape.

In solids molecules are tightly pack and very close to each other.

Their melting and boiling point are every high.

The densities of solids are also very high as compared to the liquid and gas.

There are very strong inter molecular forces are present between solid molecules.

pychu [463]

Answer:

The correct answer is a Protein

Explanation:

Proteins are macromolecules consisting of amino acids which are joined by peptide bonds.

         Protein molecule has two ends,  amino(-NH2) group is present at one end that is known as amino terminal end or N terminal end whereas carboxyl group is present at the another end that is called carboxy terminal end or C terminal end.

In the life-cycle of the malaria parasite plasmodium, where does fertilization and formation of the zygote occur?.
daser333 [38]

Fertilization and formation of the zygote occur Within the body of mosquito.

Zygote, from the Ancient Greek (zygtós), "attached, yoked," from (zygoun), "to join, to yoke," A fertilization between two gametes produces  a eukaryotic cell. The genome of a zygote, which consists of the DNA from each gamete, is what makes up a new individual creature and holds all of its genetic material.

The zygote is the first developmental stage in animals with many cells. When an egg cell and sperm cell unite to produce a new, distinct organism, a zygote is created in humans and the majority of other anisogamous species. With the aid of mitosis, the zygote can divide asexually in single-celled organisms to create identical progeny. The chloroplast DNA (cpDNA) of a Chlamydomonas zygote is inherited uniparentally from the parent with the mt+ mating type; as a result, such cells are typically uncommon. The mapping of chloroplast genetics through recombination was made possible by these uncommon biparental zygotes.

In prokaryotes, which component must disassociate to allow for elongation of the transcriptional complex? In prokaryotes, which
qaws [65]

Answer:

sigma subunit

Explanation:

Sigma subunit of RNA polymerase holoenzyme directs the enzyme towards the consensus sequences present upstream of the transcription start site. Completion of the initiation phase of transcription is followed by dissociation of sigma subunit from the transcription complex.

The protein NusA replaces the sigma subunit. The RNA polymerase leaves the promoter and starts the elongation
