Velocity is the variable which is changing during motion of skater.

Velocity is the variable which is changing when the skater moves up and down the track because moving upward on the slope decrease the speed of the skater while on the other hand, velocity increases when moving downward on the slope.

Mass of the body which is skating remain constant or can't change with height. Mass is the amount of matter present inside the body so we can conclude that velocity is the variable which is changing during motion of skater.

G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.

Explanation:

During G1, there is a great amount of protein synthesis occuring.

Explanation:

Answer:

B

Explanation:

Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.

Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.

mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

DNA stands for Deoxyribonucleic acid. It may be characterized as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.

DNA is not a single-stranded structure. While RNA is present in a single stranded form in the cell. Due to this, the double-stranded structure of DNA seems longer than that of RNA to cross the nuclear membrane in the cell. As a result of this, RNA can easily leave the nucleus but DNA couldn't.

Therefore, mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

Answer:

Why do we need to cool the mixture? DNases or restriction enzymes that destroy DNA are present in the cell's cytoplasm. They are there to protect the cell from invasion by viruses. Once the nuclear membrane is destroyed by the soap, the DNA is now susceptible to the DNases and will quickly be degraded.

Explanation:

When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump, making it easier for you to see them.

Answer:

Metaphase: During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate. Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. ... These separated sister chromatids are known from this point forward as daughter chromosomes.

proteger el medio ambiente mediante la utilización de energías renovables, crear conciencia a través del uso sustentable de los recursos naturales, disminuir el consumo, reciclar y fomentar la utilización de compuestos biodegradables  

Explanation:

La cultura del descarte en conjunción con el aumento creciente en la población mundial ha conducido a graves problemas ecológicos que afectan actualmente a la sociedad tales como, por ejemplo, el cambio climático, el cual plantea una preocupación muy seria acerca de las condiciones en las que recibirán nuestro planeta jóvenes y futuras generaciones. La mejor manera de garantizar un ambiente limpio, saludable y sostenible es fomentando el uso de energías renovables y simultáneamente reduciendo al mínimo el consumo innecesario de recursos (como por ejemplo, a través del uso eficiente del agua o electrodomésticos de bajo consumo energético). También reciclar materiales, utilizando materiales biodegradables y evitando compuestos no reciclables (tales como plásticos) representan buenas ideas para un mañana sin riesgos ambientales.
