Question

please solve me this plasma question as clearly as possible . Thank you so much

Question 2. Consider a symmetric, capacitively coupled rf discharge in argon gas having a total applied rf voltage of amplitude 800 V at a frequency f-o/2n 13.56 MHz. The plate separation is / 0.1 m, and the gas pressure is 5 mTorr. Use a low pressure discharge model, as in Example I of Section 11.2. Principles of Plasma Discharges and Materials Processing-Lieberman a) Determine the electron temperature Te in the discharge. b) Determine the plasma density no and the ion flux c) Determine the de potential of the plasma with respect to the plates and the ion- bombarding energy (in volts). d) Determine the sheath thickness sm e) Determine the total rf power per unit area required to sustain the discharge. f) Determine the rf current amplitude drawn by the discharge.

Answer 1

Answer:

1). B). Asparagine-glycine-tyrosine

2). B). Prophase I

Explanation: Exchange of chromatid segments between non-sister chromatids of homlologous chromosomes is called crossing over. It occurs in meiosis I.

3). C). 1 pair of sex chromosomes and 22 pairs of autosomal chromosomes are pictured

Explanation:

Male = 22A + XY

Female = 22A+XX

4). D). They’re the main site of photosynthesis in autotrophs

Explanation:

Chloroplast composed of a liquid-filled space known as stroma. They are found in plant cells. They are full of flattened stacks of membranes called thylakoids.

5). C). Electron transport chain.

Explanation:

Glycolysis= 2 ATP

Kreb’s cycle = 2 ATP

Electron transport chain = 32 ATP

6). B). Store

Explanation: The main role of DNA in the cell is the long-term storage of information.

7). 7). D). The body failing to respind to signals that slow the cell cycle.

8). A). Exposing a plant to a higher light intensity

9). B). Telophase

Explanation: Nuclear envelope disappears in prophase and reappears in telophase.

10). D). Anaphase II

Explanation:

Homologous chromosomes move towards to opposite poles in meiosis I. Sister chromatids move towars opposite poles in anaphase II
