Hi,
The word mutation come from word mutate, that means to change. In Biology, a mutations means a change in the DNA sequence of an organism. Since DNA sequence encodes for proteins, when a mutation occurs in part of DNA (gene) it causes a different than usual protein which had to be expressed.
For example:
- There was a gene whose sequence was: AATGGGGCCC
- A single base mutation made the sequence as: TATGGGGCCC
Now how these mutations affect an organism in which they took place?
The answer is, mutations can be beneficial, harmful and even neutral.
A mutations is beneficial when the sequence changes in such a way that the new protein gives beneficial characteristics to the organism. For instance, a mutation occurs in the DNA of bacteria which enhances its resistance against antibiotics, so the bacteria can live longer. This is a beneficial mutation for bacteria. Sometimes, the mutations can be lethal and very hamrful. For instance, when a mutation occurs in the coding region of a gene for certain trait of organism like skin type, skin color. If mutation happens in coding region of skin type, in such a way that new protein formed is not correct, it can heavily harm. Like a mutation changes the skin color of people living in hot areas from from dark to pale color. The pale color is prone to more damage than dark color, therefore, these skins are easily burnt and can causes skin cancer and other skins problems to people. Similarly, some mutations can be neutral and they cause neither benefit, nor harm, no effect on organism. These are called silent mutations because the DNA sequence is changed in such a way that new protein is same as old protein. For example there is a gene having part CCG, after mutation it changes to CCA. Both will code for the same protein Glycine and will have no effect on overall phenotype of organism.
Hope it help!
in a "neutral atom", the number of protons must be equal to the number of electrons, otherwise it would not be neutral, so yes it would still be 82
The atmospheric subduction process is not a process that has been proposed to explain the formation of precipitation.
Answer:
D Anaerobic respiration
Explanation:
The product of anaerobic respiration is the formation of either lactic acid (lactate) or ethyl alcohol as a waste product.
- Anaerobic respiration is a process that occurs in the absence of oxygen gas.
- When oxygen is lacking in cells, glcolytic process follows the anaerobic path way.
- This process produces very little energy for the body.
- During a period of intense exercise, anaerobic respiration usually occurs.
1.<span>The </span>El Nino<span> phenomenon, which occurs every three to five years, is </span>caused<span> by warmer water in the eastern Pacific Ocean
2.</span>La Nina<span> is characterized by unusually cold ocean temperatures in the Equatorial Pacific
3. Basically El Nino is when the climate in one area is warm, whereas La Nina is when the climate in one area is cold
4.El Nino would warm up Florida's temperature in the winter. Since its already a bit warm in the winter it would be kind of like summer, in a way.
5. The climate would be warm, as I said, but it would be cold if it where La Nina
6. El Nino would cause lots of droughts most likely and mess up food production. itcould also dry up some of the water too depending where you are at. Also in some cases hot weather can cause lots of pollen and some people are allergic to pollen and it just wouldn't be good at all.
There really isn't a full explanation to how it can be stopped because you can't control the weather. But what we could do is reduce the amount of gas and other chemicals we let into the air like factories for example.
I hope this helped! this took a while to make lol</span>
