What is not a contribution of the cardiovascular system to other body systems?

Biology
1 answer:
Vinvika [58]3 years ago
8 0

OPTIONS:

a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

c) Blood carries newly absorbed nutrients and water to the liver.

d) Blood circulates cells and chemicals that carry out immune functions.

e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged

Answer:

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

Explanation:

Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.  

Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs. </em>

The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is____ operon t
user100 [1]

Ans.

Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.

The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.  

Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'

Describe how a plasmid can be genetically modified to include a piece of foreign dna that alters the phenotype of bacterial cell
Ilia_Sergeevich [38]
Simple version:

First, the section with the desirable gene must be identified. Assuming that has already happened, the section of DNA must be excised from the original genome using restriction enzymes, which recognize certain DNA sequences and snip DNA at those sites. DNA ligase is used to "glue" these ends back together. The DNA is inserted into a plasmid (also with restriction enzymes), which would usually contain antibiotic-resistance genes (so they survive in an environment containing the antibiotic, which would also help show if the bacteria have been successfully transformed). 

Then comes the actual transformation process. The bacteria to be transformed are mixed with calcium chloride (which causes the bacteria to be more receptive to the plasmids) and then mixed with the plasmids. The bacterial cells are subjected to a heat shock (the solution is heated and rapidly cooled, e.g. by placing the mixture in a hot water bath and quickly transferred to ice) so they will take up the plasmid (since the temperature change makes the membrane more permeable). The bacteria are placed on a growth medium containing the antibiotic they're resistant to. Only those successfully transformed would survive.
