Motor neurones are activated and the muscles of your arm contract, moving your hand away from the sharp object.
Answer:
Explanation:
One further distinction is that EFTs can only be used to transfer money between bank accounts in your name, whereas Interac e-Transfers can be used to send money to a third party—like the colleague who spotted you lunch money the day you forgot your wallet.
Answer:
<em>d. enhances the ability of spores to penetrate the layer of stagnant or unmoving air above the fruiting body.
</em>
Explanation:
Two things rely on the movement of the spores in the air to the great heights. Velocity is one, and mass would be another. Because if the spores are to grow in the air they need both mass and speed.
Spores produced by single ascus can not accomplish this by themselves. Thereby spores are emitted by asci groups.
Spores obtain the ability to penetrate the layer of stagnant or up-moving air above the fruiting body by being released by community of asci.
Answer:
Glucose is the substance produced during photosynthesis which provides food for plants and animals in a food web.
Explanation:
The main source of energy in a food chain or food web is made by the producers. These producers are mostly plants that make food by the process of photosynthesis. As a result of photosynthesis, glucose is made as the main product whereas oxygen is made as the by-product. Glucose made is used to drive energy for all the activities of the cell. This energy, released from glucose, is carried within an ecosystem from one organism to another.
It will take <u>120 minutes</u> for the concentration to become > 15000 cells/cm³
<u>Given data:</u>
Initial concentration ( density ) = 1000 cells / cm³
Target/final concentration = > 15,000 cells /cm³
<h3 /><h3>Calculating the concentration every 30 minutes </h3><h3 />
<em>note</em><em> : Given that each cell divides every 30 minutes </em>
- <u>After the first 30 minutes </u>
Concentration = 2000 cells / cm³
concentration = 4000 cells / cm³
concentration = 8000 cells / cm³
- <u>After 120 minutes </u>
concentration = 16000 cells / cm³
Therefore after 120 minutes the concentration of the cells will be greater than 15000 cells/cm³ ( i.e. 16000 cells/cm³ )
