Daltons, a unit of molecular weight, are used to measure protein size. The mass of a hydrogen atom, which is 1.66 x 10-24 grammes, is considered to be one Dalton. Since the majority of proteins have masses in the thousands of Dalton range, the term kilodalton (kDa) is frequently used to refer to the molecular weight of proteins.
- Daltons (Da) or kilodaltons, which are units of molecular weight, are typically used to measure proteins (kDa). By comparing the sizes of standard molecular weight markers of known size that were run in parallel with the unknown samples during gel electrophoresis, one can estimate the sizes of DNA, RNA, or protein molecules that were separated on gels.
- Different techniques have been used to assess the electrophoretic mobilities of DNA polymer fragments in an agarose gel and then convert those measurements to lengths using the reciprocal method. The length estimations can be greatly distorted by the measurement technique.

Answer: False
A waterway refers to a water body that can be used for the transportation by human population. These includes rives, oceans, lakes, estuary and canals. A waterway should be wide and deep enough to allow the movement of water transportation vehicles like boats and ships. Water transportation is responsible for contaminating the water of waterways. As, the water transportation vehicles releases residues of fuel in the water, which deteriorate the quality of water and makes it unfit for survival of aquatic animal and plant species.
Hence, excess to waterways should be reduced in order to prevent water pollution. Reducing access to waterways will lead to decrease in human impact on waterways.
Therefore, the statement reducing access to waterways will lead to an increase in human impact on waterways is false.
Answer:
The system has two solutions:
(1, -1) and (0, 0)
Explanation:
We have the system of equations:
x + y = 0
x = x^2 + 2*x*y
To solve this, the first step is to isolate one of the variables in one of the equations, I will isolate x on the first one.
x = -y
Now we can replace this on the other equation, to get:
x = x^2 + 2*x*y
(-y) = (-y)^2 + 2*(-y)*y
Now we can solve this equation for y.
-y = y^2 - 2*y^2
-y = -y^2
y^2 - y = 0
We can solve this using the Bhaskara's formula:
The solutions are then:
Then the two possible solutions are:
y = (1 + 1)/2 = 1
and
y = (1 - 1)/2 = 0
Suppose that we take the first one, y = 1.
Then the solution for x is given by "x = -y"
Then:
x = -1
This means that one solution of the system is (-1, 1)
If we take the other solution for y, y = 0
The value of x will be:
x = -y = -0 = 0
Then another solution of the system is (0, 0)
