Answer: C. 5 A C G U U A G G 3

Explanation:

A primer is a short nucleic acid sequence that provides a starting point for DNA synthesis. It is a short strands of RNA.

DNA and RNA are made up of different sequence of nucleotides.

Adenine (A), Cytosine (C), and Guanine (G) are nucleotides found in both DNA and RNA.

Only DNA contains Thymine (T) and only RNA contains Uracil (U).

Pairing in DNA:

A to T

G to C

Pairing in RNA:

A to U

G to C.

Therefore DNA and RNA can still be complementary to one another by substituting for thymine (T) and Uracil (U) where required.

Starting from the underlined T (T) of the template, we have 3 T G C A A T C C 5.

If we are to pair the complementary RNA nucleotides, we will have 5 A C G U U A G G 3

Feliz [49]

Answer:

1. Ends of the respiratory branches are called alveoli.

2. C. To control blood flow to different areas of the body depending on activities

Explanation:

1. The trachea divides into left and right primary bronchi which in turn divide multiple times upon entering the lungs and make the bronchial tree.

The final branches of the bronchial tree are the terminal bronchioles that lead to alveoli. The alveoli are the balloon-shaped structures and serve as the site of gas exchange between the blood and inhaled air.  

2. The opening and closing of sphincters of capillary beds regulate the direction of blood flow. The opening of sphincters allows the blood to flow into associated branches of capillary beds while closed sphincters direct the blood from arterioles to venules via thoroughfare channel.

This local change in blood flow is responsible for the autoregulation of blood flow to different tissues to match their respective metabolic demands. For example, during physical activity, more blood is directed to skeletal and cardiac muscles.

Help!! I'm doing a lab report and am unsure which variables are independent, dependent, and controlled. My lab is due tomorrow
victus00 [196]

Im not sure but if you think of it, the one that you didn't put any salt is a independent  variable because it doesn't really rely on anything it doesn't have salt. The Dependent variable would be the 2nd and the 3rd cup because it doesn't have much salt but the 4th cup has lots of salt so its basically controlled. Hope it helps !

Where exactly on the map does the size and concentration of the boxes appear to be the highest?
pav-90 [236]

The concentration and size of boxes the same at all locations is not the same size. The deaths due to cholera vary depending upon the location. The relative sizes represents that died at that certain spot.

Explanation:

The black boxes represent relative numbers of death due to cholera. Cholera is referred to as a disease of poverty because of the lack of social development in the areas in which it occurs. Crowded camps are fertile ground for a cholera outbreak. Other humanitarian crises including flooding and earthquakes, civil unrest or war that causes disruption of water and sanitation systems.
