When talking about evolution, a good example is bacterial resistance to antibiotics.
We start with a bacteria colony, and in contact with antibiotics, most of them die.
Some of them in the colony do not die and took that antibiotic to create a mutation of its DNA to be resistance to that.
They evolved survive that antibiotic.
<u>Answer:</u>
<em>The steps in making packaging and exporting a protein from a cell are listed below in the following points:</em>
- <em>Protein is made from the Ribosomes.</em>
- <em>These proteins are gathered in the endoplasmic reticulum. </em>
- <em>From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.</em>
- <em>The Golgi bodies modify the protein to suitable forms that can be absorbed.</em>
- <em>Finally it is transported to all part of cells in our body.</em>
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground.
Hey there,
When lifting, the paramedic should spread his or her legs <span>shoulder-width</span> apart?
This reason could be understandable and common sense. You do not want to open someones legs like the size of your full arm, because you could break there legs, this is why it is necessary why to do this.
