4. The TATA box helps bind in the correct place.

AlexFokin [52]

Answer:

The TATA box helps bind the RNA polymerase in the correct place.

Explanation:

The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.

The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.

_________ blood enters the right atrium; it flows through a valve into the right ________, which pumps it through _______, which

Lerok [7]

Specialized tissue on the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the _______ and the atrioventricular bundle (bundle of His) toward the ventricles.atrium (pl. atria)One of two upper chambers of the heart.capillarySmallest blood vessel. Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastoleRelaxation phase of the heartbeat.

Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

1 km = 1000 m

1 m = 100 cm

1cm = 10mm

1 km = 1,000,000 mm

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y
