Answer: Option D.

Explanation:

Larynx is an organ located at the neck. It is also called voice box. It is use for breathing,producing sounds and protect the trachea from food passage. There is a cartilage that lies the top of the larynx called epiglottis. During swallowing, the larynx elevates and epiglottis falls on the opening of the larynx thereby preventing food from entering the trachea.

barxatty [35]

Answer:    

The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)

Explanation:

  • <u>Interphase</u><u>:</u> Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F)  
  • <u>Prophase</u>: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)
  • <u>Metaphase:</u> The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area.  (FIGURE C)
  • <u>Anaphase</u>: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H).
  • <u>Telophase</u>: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)
  • Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D).
  • Decondensation of the genetic material of each new cell (FIGURE B).

Scorpion cells undergo aerobic respiration, during aerobic respiration oxygen is used, and ATP is created.

During aerobic cellular respiration, glucose is absorbed with oxygen to form ATP, which can be used by cells. Carbon dioxide and air are formed as by-products. The overall extension to aerobic cellular respiration is: During cellular respiration, glucose and oxygen form ATP.

This process takes place in the mitochondria. So respiration occurs in animals and plants because both have mitochondria.

Aerobic respiration is respiration that requires oxygen while anaerobic respiration is respiration that does not require oxygen. Aerobic respiration consists of several stages, namely: glycolysis, oxidative decarboxylation, Krebs cycle, and the electron transport chain which have been discussed in the previous material.

zhenek [66]

Answer:

D. Particle A orbits the nucleus, and Particle B is located in the nucleus​

Explanation:

Here since both particles are of the same atom and particle A is much lighter we can infer that Particle A is electron because electrons are much lighter than protons which are Particle B in this case. Thus, particle A orbits nucleus as an electron does and particle B is in nucleus where protons are.
