How did prostitutes prevent pregnancy in the old west?
bazaltina [42]

Hello, that is a very good question!


Back then there was no such thing as 'birth-control', hence they never actually prevented pregnancies, of course there were services that provided 'different' penetration but that could also result in pregnancies.


The popular method of not giving birth [prevent pregnancy] was to kill the baby while still carrying [termination], in other words have a miscarriage.

There many various methods during that time (herbs, beating, old cloth hanger).


Hope this helped,

If you measure the rate of respiration of plant root hair cells, would you expect it to be the same as, more than, or less than
DaniilM [7]

Answer:

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.<em>Plant respiration occurs 24 hours per day</em>, but <em>night respiration is more evident since the photosynthesis process ceases.</em> During the night, it is very important that the <em>temperature is cooler than during the day</em> because plants can experience stress. Imagine a runner in a marathon.

roots respire too!

One of the functions of the substrate is <em>to serve as a site for air exchange between the root zone and atmosphere</em>. In other words, <em>roots breathe oxygen like we do</em>. Different plants have different oxygen requirements for their root systems.

For example,

<em><u>the root system of a poinsettia requires a lot of oxygen, so it is best to use a substrate with high air porosity, while hostas can live well in a substrate with a high water holding capacity. </u></em>

Which molecule from glycolysis or the citric acid pathway serves as the building block for lipid synthesis?
Mariana [72]

Answer: Acetyl-CoA

Explanation:

Acetyl-CoA can be obtained from the pyruvate, the end product of aerobic glycolysis. Also, Acetyl-CoA is the one of the starting materials of citric acid cycle.

For lipid synthesis, biotin carries activated CO2 that is incorporated into acetyl-CoA to form Malonyl-CoA, which is then elongated to yield various lipids of different length.

Thus, Acetyl-CoA is the building block of lipid synthesis
