Ans.

DNA acts as genetic material in all living organisms that store and transmit genetic information from one to next generation. DNA sequence carries instructions for the expression of genes to make proteins, responsible for different phenotypic characters of individuals.

The DNA, first synthesizes mRNA molecule that carry information for the protein synthesis, in the form of codons and code for a specific polypeptide chain or protein.

The sequence present in DNA determines the amino acid sequence in protein encoded by the DNA. Change in DNA sequence affects gene expression as it leads to change in mRNA sequence, and thus, change in sequence of amino acid of the resulting protein.

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a
Agata [3.3K]

Answer:

2,855 is the size of the colony of mosquitoes after 4 ​days.

Explanation:

The law of uninhibited growth is given as:

A=A_o\times e^{k\times t}

A_o= Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

1300=1000\times e^{k\times 1 day}

k = 0.2623 day^{-1}

Population size of mosquitoes after 4 days

A_o=1000, k= 0.2623 day^{-1}

A =? , t = 4 days

A=1000\times e^{ 0.2623 day^{-1}\times 4 days}

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 ​days.

Anestetic [448]
The measurements taken by Jay are least likely to contain random errors.

When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.

bogdanovich [222]
Flight; fight
The sympathetic is used to speed things up, stopping things like digestion in order to supply more blood to the heart and lungs, while the parasympathetic does the opposite; digesting food and working on internal things while the heart rate and breathing rate slow.
