<u><em>-What are the differences between the plant and animal cells?
</em></u>
Plant cells:
- Cell wall present
-Nucleus usually lies near periphery due to vacuole.
- Centrosome is usually absent from higher plant cells, except lower motile cells.
- Plastids are present, except fungi.
Animal cell:
- Cell wall absent.
- Nucleus present near centre.
- Usually centrosome is present that helps in formation of spindle fibres.
- Plastids are absent.
<u><em>-Describe the structure of an ATP module.
</em></u>
ATP plays an important role in releasing and storing energy in cells. It is an ideal source of energy because ATP easily releases and stores energy by breaking and re-forming the bonds between its phosphate groups. The ATP module is composed of three components. These phosphates are the key to the activity of ATP.
its asking for you to check the box if the item is preset in the cell hint: eukaryotic cells have a nucleus so you would say yes in the box. but since prokaryotic cells don't have a nucleus say no in the box
A haploid cell during meiosis means that a cell has half the number of chromosomes as the daughter cell however, when gametic fertilization happens the parent cell will then be re-established. Meiosis is another type or way of cell division wherein one homologous chromosome is segregated into another and new gamete. There are actually two successive nuclear division that is bound to happen in each haploid cell, that is Meiosis I and Meiosis II. Meiosis was then known as reduction or cell division.
The graph which best represents this phenomenon is graph C.
The result of disruptive selection is the selection of the most extreme phenotypes/genoypes, and the decrease of the middle terms.
