We can tell from their structure that fatty acids are a good source of energy because of their large number of carbon-hydrogen and carbon-carbon bonds that they contain. Most fatty acids have straight chain compounds with an even number of carbon.
Answer:
The correct answer is: Attachment.
Explanation:
- Pilus are thread like structures which are present on the surface of the bacterial cell.
- They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
- Pilus also mediate the process of conjugation in some bacterial cells.
- Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
- Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
- A defective pilus will affect all the above processes, resulting in death of the bacteria.
The first colorimeter is precise, but it is not accurate. It seems to have a zero error of -5.
We can conclude its precision because the readings are closely grouped, but its lack of accuracy is due to its variation from the actual value. Moreover, the variation is consistently of 5 points lower than the actual value, so its zero error may be -5.
The second colorimeter may be referred to as being accurate.
Answer:
As the blood pressure in each of the blood vessels is measured, it can be predicted to be lowest in the capillaries.
Explanation:
Options for this question are:
- <em>Artery.</em>
- <em>Arteriole.</em>
- <em>Capillaries.</em>
- <em>Venule.</em>
- <em>Vein.</em>
Once the blood leaves the heart, it is distributed in a network of arterial vessels -arteries and arterioles- that bridge the venules and veins through the capillaries. Blood pressure depends on the pumping strength of the heart and the force that blood produces on the vessel walls. There is a marked difference between arterial and venous pressure. Some conclusions can be drawn from this:
- <em>Blood pressure is higher the closer the vessel is to the heart.
</em>
- <em>The larger the vessel, the more blood is contained and the more blood pressure is recorded.
</em>
Based on this, it can be deduced that the blood vessels with the lowest pressure are the capillaries, with very thin walls and where gas and nutrients or metabolites enter and leave the vessel.
The question gives an answer, but does not explain why.
