Organize these rock layer from youngest to oldest
Breccia

Shale

Answers

Conglomerate,Shale,Dolostone

From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale, and as per geology, the principle of superposition states that in a sequence of layered rocks, the youngest layer is on top and the oldest layer is at the bottom.

What are rock layers?

Breccia is the youngest layer in the sequence. Breccia is a coarse-grained sedimentary rock made up of angular fragments of other rocks that have been cemented together. It is formed through a process called brecciation. Conglomerate is also a coarse-grained sedimentary rock, but unlike breccia, its fragments are rounded and well-worn, indicating that they have been transported over a distance by water or wind before being deposited and cemented, and dolostone is older than both breccia and conglomerate. Shale is the oldest layer in the sequence.

Hence,    From youngest to oldest are Breccia, Conglomerate, Dolostone, and Shale.

TRANSCRIPTION AND TRANSLATION

Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation.

Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA.

The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.

DNA → RNA → Protein

DNA and RNA are similar molecules and are both built from smaller molecules called nucleotides. Proteins are made from a sequence of amino acids rather than nucleotides. Transcription and translation are the two processes that convert a sequence of nucleotides from DNA into a sequence of amino acids to build the desired protein.

These two processes are essential for life. They are found in all organisms – eukaryotic and prokaryotic. Converting genetic information into proteins has kept life in existence for billions of years.

DNA and RNA

RNA and DNA are very similar molecules. They are both nucleic acids (one of the four molecules of life), they are both built on a foundation of nucleotides and they both contain four nitrogenous bases that pair up.

A strand of DNA contains a chain of connecting nucleotides. Each nucleotide contains a sugar, and a nitrogenous base and a phosphate group. There is a total of four different nitrogenous bases in DNA: adenine (A), thymine (T), guanine (G), and cytosine (C).

A strand of DNA is almost always found bonded to another strand of DNA in a double helix. Two strands of DNA are bonded together by their nitrogenous bases. The bases form what are called ‘base pairs’ where adenine and thymine bond together and guanine and cytosine bond together.

Adenine and thymine are complementary bases and do not bond with the guanine and cytosine. Guanine and cytosine only bond with each other and not adenine or thymine.

There are a couple of key differences between the structure of DNA and RNA molecules. They contain different sugars. DNA has a deoxyribose sugar while RNA has a ribose sugar.

The chemiosmotic hypothesis states that the energy for the production of ATP during photosynthesis comes from the Mitochondria.

The mitochondria is regarded as very important and the power(energy) house of the cell as a lot of ATP synthesis activities takes place in this organelle.

The hypothesis was used to prove that most of the ATP production that takes place in respiring cells comes from the electrochemical gradient present  across the inner membranes of mitochondria.

ATP is formed from the break down of the molecules rich in energy such as glucose and the use of energy of NADH and FADH₂ which are formed from its breakdown.

the electron transport chain consists of a series of membrane-bound carriers that shuttle protons and electrons to nadh. true or false?

Answers

Answer:

ture

Explanation:

The statement "the electron transport chain consists of a series of membrane-bound carriers that shuttle protons and electrons to NADH" is absolutely false.

What is the Electron transport chain?

The electron transport chain may be defined as a sequence of four protein complexes that significantly perform a couple of redox reactions in order to construct an electrochemical gradient that directs to the formation of ATP in an overall system that is named as oxidative phosphorylation.

The electron transport chain typically includes the series of electron transporters that are generally embedded in the inner membrane of mitochondria in order to shuttle down the electrons only from NADH and FADH2 to molecular oxygen.

While the given statement reveals that electrons and protons both shuttle to NADH but FADH2 is also involved.

Therefore, the statement which is given about the electron transport chain is definitely false.

Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.

What is chlorophyll?

It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.

During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.

It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.

Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.
