A geneticist wants to determine what mutation in a DNA molecule changed the structure of a specific protein. What would the scientist need to know before planning the investigation?
The normal sequence of bases that code for the protein
Whether the mutation was a substitution, insertion, or deletion
The total number of bases in the DNA molecule
How many thymine bases are in the DNA molecule
A mutation is any change in the sequence of DNA because of any reason such as deletion, insertion, etc. To determine the mutation in a DNA molecule changed the structure of a specific protein scientists should know the normal sequence of bases that code for the protein.
What is mutation?A mutation is a random change in the DNA sequence either due to insertion, deletion, or substitution.
By mutating a gene's code for making a protein, a variant can leads to a protein's improper functioning or to not being produced at all.
Scientists must mandatorily determine the normal base sequence of the protein code before investigating the mutation in the DNA sequence for a particular protein.
Thus, the correct option is A.

As we exercise, our body produces heat through the process of cellular respiration. Although our body temperature does increase, the temperature change is slow and we are able to maintain a homeostatic temperature. Which property of water explains why our body temperature is slow to change
Answer: Ability to moderate temperature
Explanation: the water is able to moderate temperature to maintain homeostasis. It tries to cool down when it is extremely hot and heat up while we are cold. If water didn’t have this property then we would not be able to live in places like New York or Massachusetts due to the extreme temperatures

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct
Hope this helps!

Stitch classification according to ASTM
The chain stitch. Hand stitch. Double backstitch stitch. Multiple chain stitch. Cover stitch. Single Thread Double Topstitch Stitch.Explanation:
how does competition limit the amount of individuals in populations?
Explanation:
Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

Which of the following is a potential benefit of a disturbance to a
community?
O a decrease in availability of resources
o the community may be unable to recover
O some species depend on disturbances
O links between the native species break
Answer:
I'm pretty sure it is 'some species depend on disterbences'
The potential benefit of a disturbance to a community is that some species depend on disturbances.
Importance of disturbance in a communityCommunity disturbance can be defined as a force, which may be biological or non biological, that results in mortality of organisms or loss of biomass.
Different types of disturbance that can affect a community include:
fires, storms, diseases, volcanic eruptions, earthquakes, contaminant spills, and land clearing.Some species depends on community disturbance because the cleared habitat caused by the disturbance leads to species movement into the newly cleared area, that is, secondary succession.
