Unlike other organelles, chloroplasts and mitochondria contain their own genetic information in the form of A) DNA. B) RNA. C) purine. D) pyrimidines

Answers

Answer 1

Answer:

The right answer is A) DNA.

During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.

Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes

Answer 2

Answer:

A DNA

DNA is found in mitochondria and chloroplasts of eukaryotic cells like plants and animals and is important to reproduction of the cell.

What underlying theme do the four molecular techniques share?

Answers

All of the following such as DNA sequencing, PCR, electrophoresis, and DNA hybridization are used in molecular techniques for genetic analysis.

What is the genetic analysis?

Genetic analysis is the science of identifying, studying, and diagnosing genetic variations in an organism's DNA. The most common molecular techniques used in genetic analysis include DNA sequencing, PCR, electrophoresis, and DNA hybridization.

All of these techniques share the underlying theme of genetic analysis, with a focus on the analysis of genetic variations in DNA. DNA sequencing is used to read and interpret the genetic code, while PCR is used to amplify specific DNA sequences, enabling their detection.

Electrophoresis is a technique that separates DNA fragments based on their size, charge, and other physical properties, and DNA hybridization is a technique that detects and quantifies specific DNA sequences by binding them to complementary DNA probes.

Nanotechnology, the atomic material is molecular and supramolecular levels of control. Also mentioned as the oldest and most common definition of nanotechnology, molecular nanotechnology today, exactly 'the control of atoms and molecules for the production of macroscale product represents a particular purpose. The more general definition of Nanotechnology National Nanotechnology Initiative by later. National Nanotechnology Initiative nanoteknoliji of 'at least one of size up to 100 nanometers in size control agent 1' is defined. Demonstrates the fact that this definition; quantum mechanical effects are important in the quantum-field scale. Thus, the definition rather than a specific technological purpose, turned into a category covering all areas of research addressing the special nature of the substances formed under the size limit of the types of technology and research. That's why "of nanotechnology" and the "nanoscale technologies" of the plural form 'is very common that the common feature of size and Applications expressed a wide range of research. Potential applications (including industrial and military) has invested billions of dollars to the state because of the diversity of nanotechnology research. US National Nanotechnology Initiative thus made $ 3.7 billion investment. The European Union and Japan has invested $ 1.2 billion, $ 750 million. Nanotechnology is defined in magnitude for earth science, organic chemistry, molecular biology, semiconductor physics, contains areas of science such as micro fabrication and naturally is very wide.

From the extension of the basic device physics to completely new approaches to non-atomic molecular self-assembly, from developing new materials with dimensions on the nanoscale, they vary from the direct control of matter on the atomic scale.

Do you think that scientists will ever run out of things to study? explain your reasoning

Answers

Answer:

Explanation:

I do not believe that scientist will ever run out of things to study because there is so much we don't know so the scientists will try figuring it out for maybe a couple years but they might restudy things from the past to help us now.

Answer:NO

Answers

Through the phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent protein Kinases are dependent on cyclins, another class or regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.

Carbohydrates _____. in the body are primarily fats
are primarily sugars and starches
are the most readily available source of energy for organisms
are the largest of the four main biological macromolecules

Answers

Answer:

are the most readily available source of energy for organisms is the correct answer.

Explanation:

Carbohydrates contain hydrogen, carbon, and oxygen.

Carbohydrates are the most readily available source of energy for organisms.

It is the most necessary source of energy for human diets.

Carbohydrates are broken down into sugars(fructose, galactose, and glucose)and it used as the source of energy.

Carbohydrates are present in fruits, vegetables, grains, and milk products.

Carbohydrates are the simplest form of nutrition and it is metabolized our bodies that whys it is considered an available source of energy.

are the most readily available source of energy for organisms.

Answers

I think that they are both correct: homeostatis maintains the same internal conditions regardless of the outside environment or activity: these conditions include temperature, as Jenna says, and oxygen level, which is what Allen means.

Which factor has the least effect on the strength of an electromagnet? A. The length of the connecting wires
B. The number of coils of wire.
C. The material of the core.
D. The strength of the battery

Answers

The length of the connecting wire has the least effect on the strength of an electromagnet.

What factors influence the strength of an electromagnet?

An electromagnet is a type of magnet where an electric current creates the magnetic field. The wire that makes up an electromagnet is typically twisted into a coil.

A magnetic field is produced by a current flowing through the wire and is concentrated in the hole, designating the centre of the coil.

The type of core material, the strength of the current flowing through the core, the number of wire turns on the core, and the size and form of the core are all factors that determine an electromagnet's strength.

Stronger magnetic fields can be created by using alloys like alnico, which is an alloy of aluminium, nickel, and cobalt.

The strength of the electromagnet's magnetic field increases when:

(a) the current increases

(b) the number of turns increases

(d) Soft iron core inserted into magnetic coil
