The correct answers are as follows:
1. C.
Cells have the capacity to divide and reproduce other cells, this feature makes it possible for them to reproduce and given birth to offspring. Cells can divide through two major ways, these are mitosis and meiosis. Cell division by mitosis give rise to two identical cells while cell division by meiosis give rise to four daughter cells.
2. B.
Vacuoles in cells have functions that are corresponding to that of human lungs. The human lungs are the ones responsible for conducting oxygen from the air into the body through the nose and mouth, thus allowing the oxygen to enter the blood, they also move out carbon dioxide, which is a waste product from the blood into the external environment. Vacuoles in cells perform similar functions by gathering and storing waste products, which are eventually released to the external environment. Vacuoles also function in maintaining the right pH in the cell.
Answer: The color would be light red
Explanation:
Apple juice is derived from apples which are rich in vitamin C. Chemically, vitamin C is an acid called ascorbic acid and apple juice also contain acids like folic acid and Pantothenic acid.
Hence, it is to be considered as acidic in nature.
So that, pH of apple juice is found to be in the range of 2.9 - 3.5.
Hence, the Colour of pH will be Light Red
Llamamos pigmentos respiratorios a un grupo de proteínas que tienen la propiedad de combinarse de forma reversible con oxígeno molecular. Por esa razón, pueden transportar oxígeno, captándolo en un lugar y liberándolo en otro.
metals (left side of periodic table) become positive ions so calcium would be the answer
Answer:
The best explanation if we observe an epithelial cell with chromosomes are visible and two cell nuclei is that the cell has just gone through telophase but not cytokinesis (option b).
Explanation:
A somatic cell, when found in mitosis, exhibits the chromosomes distributed in both poles and the outline of two nuclei in the telophase phase, just before cytokinesis.
In mitotic telophase:
- Chromatids, which are chromosomes, are found in the cell poles.
- It initiates the formation of the nucleus membrane.
- The chromosomes begin to turn into chromatin.
- Disappearance of the mitotic spindle, duplication of organelles and cytoplasmic invagination.
The division and differentiation of the nuclei in telophase is called karyokinesis. Later, cytokinesis occurs, where the daughter cells are separated.
The other options are not correct because:
<em> a and d. In the other phases described, </em><em><u>S and G1,</u></em><em> no chromosome distribution is observed at the poles.</em>
<em> c. A somatic cell does not experience </em><em><u>meiosis</u></em><em>.</em>
