A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells
In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place
hope it helps you :)
Instead in our hands... something else happens rills or groove shaped lines are formed in our fingers.. it is an adaptation for our body to provide for some friction in water...
Answer:
Meiosis I, a reductional division of two haploid cells produces offspring cells that are not genetically identical with the event of recombination. Haploid girl cells have half the original/parent cell chromosomes.
Explanation:
meiosis II, an equational or mitotic division, divides the haploid cells created in meiosis I to produce four identical daughter cells that ultimately form the male/female gametes (egg/sperm).
Here chromatids split in contrast to meiosis I when homologous chromosomes apart.
Answer:
the answer is C
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use
To test for side effects and rare effects (the bigger the sample size, the more likely that wired things may occur)
Answer:
Explanation:
Oil sand is an unconventional source of oil. It requires specialized technology and great expertise to win oil from associated waste materials.
The reason why some companies bother about such oil source is explained below;
- Prevailing cost of oil in the world market makes it profitable to extract these oil from sands. A high cost of oil crude oil is a good cause to produce oil form oil sands.
- Development of new technology can catalyze interest in profitable exploration from unconventional sources.
- Economic policies can also favor the production of this source of oil.
- Demand for oil in the market can jack up production levels that can also be met by oil from oil sand.
