What is the function of the large central vacuole
Rudik [331]

Answer:Una vacuola es un orgánulo celular presente en todas las células eucariotas vegetales. También aparece en algunas células procariotas y eucariotas animales. Las vacuolas son compartimentos cerrados o rodeados por la membrana plasmática ya que contienen diferentes fluidos, como agua o enzimas, aunque en algunos casos puede contener sólidos, por ejemplo azúcares, sales, proteínas y otros nutrientes. La mayoría de las vacuolas se forman por la fusión de múltiples vesículas membranosas. El orgánulo no posee una forma definida, su estructura varía según las necesidades de la célula en particular.

La célula vegetal inmadura contiene una gran cantidad de vacuolas pequeñas, que aumentan de tamaño y se van fusionando en una sola y grande a medida en que la célula va creciendo. En la célula madura, el 90 % de su volumen puede estar ocupado por una vacuola, con el citoplasma reducido a una capa muy estrecha junto a la pared celular.

What happened to Bryson's heart beat and breathing rate as he pedaled uphill? Why? Please answer
elixir [45]

I am not sure because there may be more context, but here is what I am guessing the answer is.

As Bryson pedaled uphill both his heartbeat and breathing rate increased. His breathing rate increases to provide the body (more specifically, exercising muscles) with oxygen at a higher rate and his heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently.

Suppose virus A has a viral genome of 19,000 bp, and 10,000,000,000 viruses are replicated in an infected individual in a single
Kitty [74]

Answer:

1 day.

Explanation:

From the given information:

The rate of mutation induced by RNA polymerase is:

\implies \dfrac{1}{10000}= 0.0001

Since the genome comprise of 19000 bp;

To complete a single replication, the viral cycle induce: = \dfrac{19000}{1000}

= 1.9 \ mutation \\ \\  \simeq 2 \  mutation

However, in a single day; 10,000,000,000 viruses are reported to be replicated.

Hence, if a virus has 2 mutations; Then 10,000,000,000 virus will have:

= \dfrac{10,000,000,000}{2} \\ \\ = \text{5000000000 \ mutations \ in \ a \ half \ day which is half} \\ \\ \text{ the given no of the replicated virus}

SO, to round this up to whole number, it will take 1 day (s) to overcome the therapy.
