Biology
1 answer:
earnstyle [38]3 years ago
7 0

Answer: The blanks can be correctly filled up with prophase I and metaphase II.

Explanation:

In females, finite number of oocytes are present since birth. The process of oogenesis initiate in embryonic stage only. However, oogonia divide and mature to form primary oocytes. These primary oocytes start meiotic division but arrest in prophase I stage before birth.

After a girl attains puberty, one primary oocyte resumes its division each month during a menstrual cycle. The primary oocyte divides to form secondary oocyte and polar body.

Polar bodies degenerate after completing meiosis II. However, secondary oocyte halts its division again at metaphase II until fertilization takes place. Once fertilization takes place it completes its meiosis II and results into mature ovum and polar body.

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture
masya89 [10]

The question is incomplete, the complete question is:

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture? A) The temperature will increase. B) The temperature will decrease. C) The temperature will remain unchanged. D) The temperature would fluctuate up and down.

Answer:

The temperature will increase

Explanation:

Temperature is defined as the average kinetic energy of the molecules of a body. Increasing the kinetic energy of the molecules will also increase the temperature of the molecules.

Similarly, kinetic energy is proportional to temperature. Hence an increase in the kinetic energy of molecules also leads to increase in the temperature of the system.

A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structu
hammer [34]

Answer:

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  

Explanation:

The structure found on the outside of the onion cell is the cell wall, which is specific to plants. The structure found on the outside of the skin cell is the cell membrane, which is found on all cells.

Structure X is not living, and structure Y is living.  - this is false, both animal and plant cells are living.

Structure X can be found in some human cells, and structure Y can be found in some plant cells.  - this is false, the opposite is true.

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.  - this is true structure X is the plant cell wall, and structure Y is the cell membrane

Structure X is semipermeable, and structure Y is selectively permeable. Semi-permeable and selectively permeable are essentially the same thing - it means the barrier allows some substances to pass through but not others.
