Older oceanic crust, which is more dense than continental crust, has long since been recycled in the process of subduction. Credit: U.S. Geological Survey. Plate tectonics shapes the surface of our planet, but it also runs much deeper: Plate movement is the surface expression of convection in Earth's interior.

Answer:

The tectonic plates appeared when the earth began to cool, where the water flooded the earth. The earth that was submerged originated the tectonic plates.

Explanation:

Plate tectonics are large semirigid rock blocks that make up the earth's crust. The Earth is divided into fourteen main tectonic plates, which move slowly and continuously over the mantle, and can approach or move away from each other.  The movement of the plates results in the formation of mountains, oceanic pits, volcanic activities, earthquakes and tsunamis.

The formation of tectonic plates was a result of the cooling and flooding of the earth. When the earth began to cool, where water flooded the earth. The submerged earth originated the tectonic plates.

<h3>What is Abortion?</h3>

The term "abortion" refers to the removal or evacuation of an embryo or fetus in order to end a pregnancy. Miscarriages, also known as "spontaneous abortions," are abortions that take place naturally and happen in 30% to 40% of pregnancies. An induced abortion, or less frequently "induced miscarriage," is when pregnancy is intentionally ended. Abortion, when used without modification, typically refers to an induced abortion.

Induced abortion is one of the safest medical treatments when performed correctly. The probability of maternal death in the US is 14 times lower following an induced abortion than following childbirth. Unsafe abortions—those carried out by practitioners without the required training or in circumstances with insufficient resources.

Alex Ar [27]
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).

An E. coli F(+) cell
Phantasy [73]

Answer:

The correct answer will be option- C.

Explanation:

The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.

These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.

Thus, option- C is the correct answer.
