Jenny, a healthy young woman, had a battery of tests during a physical for a new job. Her RBC count was at the higher end of the

normal range at that time, but four weeks later it was substantially elevated beyond that. When asked if any circumstances had changed in her life, she admitted to taking up smoking. How might her new habit explain her higher RBC count?

Answer:

Smoke-induced oxidative stress limited the oxygen-carrying capacity of the previous red blood cells

Explanation:

The red blood cell (RBC) contains hemoglobin which helps in the transport of oxygen. However, the Jane's smoking must have induced oxidative stress to the cells of her body including RBC, thus compromising it's oxygen-carrying capacity.

Hence Jane's body increased RBC count in order to maintain oxygen supply to all cells of her body.

What is a cells DNA like the books in a library
tino4ka555 [31]
Think of it this way:

DNA inside cells store all the genetic information on a person's looks, eye colour, hair colour etc. It makes them unique. The analogy of being like books in a library basically suggests that in a library there is so much information and every book is different with different knowledge... That's basically what DNA is; millions of different information things.

You are conducting a CRISPR-Cas9 experiment. You transform a cell with Cas9 and a guide RNA (contains the scaffold and guide seq
SOVA2 [1]

Answer:

Cas9-sgRNA cannot align with targeted DNA sequence

Explanation:

Without a PAM sequence, the CRISPR-sgRNA (small guide RNA) complex cannot align with the targeted DNA sequence. Therefore, you cannot perform experiments (e.g. gene editing) using CRISPR-Cas9.

Where do plants obtain the oxygen necessary to utilize foods? directly from products of photosynthesis from the splitting of wat
IceJOKER [234]

Answer:

from the splitting of water molecule.

Explanation:

The splitting of water molecules  by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis  of enzymes of Photo system 11.

It involves the splitting of water molecules into;

hydrogen ion/protons.

Oxygen

and electron.

<u> Oxygen is  the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.

the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02  to form carbohydrate in light independent reaction
