Explain why Calix's cells having more DNA than a normal cat meant point mutation was not the cause.

1 answer:

4 0

Point mutation. Point mutation, change within a gene in which one base pair in the DNA sequence is altered. Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations.

I) Predict which of the liquids would cause the largest decrease in mass of a potato stick

rjkz [21]

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.

Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

34kurt

Answer:

$0.136$ meter

Explanation:

The following equation will be used to solve this question -

$P_{atm} + \frac{1}{2} (rho)v^2 + (rho)gh = P_{inject} + \frac{1}{2}(rho)v_{inject}^2 + (rho)gh_{injec}$

$P_{atm} -P_{injec} = 1400\frac{N}{m^{2} }$

Velocity is zero.

Removing out the nullified terms from the above equation, we get -

$(rho)gh = P_{injec}\\1050 * 9.8 * h = 1400\\h = \frac{1400}{1050*9.8} \\h = 0.136$ meter

Hence, top of the liquid in the bottle must be at a height of $0.136$ meter.

Which process is part of the carbon cycle?

nexus9112 [7]

Answer:

respiration

Explanation:

The key processes in the carbon cycle are: carbon dioxide from the atmosphere is converted into plant material in the biosphere by photosynthesis. organisms in the biosphere obtain energy by respiration and so release carbon dioxide that was originally trapped by photosynthesis.
