Imagine you are an astronomer who recently discovered a star with a system of planets. What
irina1246 [14]

The planets closest to the star are rocky planets formed by elements with high melting points. Moreover, planets far away are gaseous planets and they are composed of elements with lower melting points.

<h3>Rocky planets and gaseous planets</h3>

The rocky planets consist of silicate rocks and/or metals, whereas gaseous planets are mainly composed of hydrogen and helium.

The rocky planets of the solar system include planets closest to the sun, i.e., Mercury, Venus, the Earth, and Mars.

The gaseous planets of the solar system include faraway planets, i.e., Jupiter, Saturn, Uranus, and Neptune.

Which molecule is active during the last step of DNA replication?
stepan [7]

Correct answer: Option D- DNA ligase

Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.

The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.

Describe and explain how blood flows from the foot to the lungs.
Natali5045456 [20]

Answer:

lungs:

The blood first enters the right atrium.

The blood then flows through the tricuspid valve into the right ventricle.

When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.

The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

It then leaves the lungs to return to the heart through the pulmonary vein.

The blood enters the left atrium.

It drops through the mitral valve into the left ventricle.

The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.

Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.

The vena cavas pump blood into the right atrium and the cycle begins all over again.
