National Industrial Goods and Technology Expo- Glocal Khabar
Kathmandu, February 19, 2018: Cottage and Small Industries Development Committee is set to organize the twenty-ninth edition of National Industrial Goods and Technology Expo from March 23, 2018 at Bhrikutimandap, Kathmandu.
The motto of the five-day event is ‘Let’s use home-made products, move ahead towards prosperity.’ The committee has shared that handicrafts, wool and bamboo products, goods made from handmade papers, different types of pickles and Palpali Dhaka would be put on display in the expo.
Answer:
Explanation:
The types of mutations include:
Missense mutation
This type of mutation is a change in one DNA base pair that results in the substitution of one amino acid for another in the protein made by a gene.
Nonsense mutation
A nonsense mutation is also a change in one DNA base pair. Instead of substituting one amino acid for another, however, the altered DNA sequence prematurely signals the cell to stop building a protein. This type of mutation results in a shortened protein that may function improperly or not at all.
Insertion
An insertion changes the number of DNA bases in a gene by adding a piece of DNA. As a result, the protein made by the gene may not function properly.
Deletion
A deletion changes the number of DNA bases by removing a piece of DNA. Small deletions may remove one or a few base pairs within a gene, while larger deletions can remove an entire gene or several neighboring genes. The deleted DNA may alter the function of the resulting protein(s).
Duplication
A duplication consists of a piece of DNA that is abnormally copied one or more times. This type of mutation may alter the function of the resulting protein.
Frameshift mutation
This type of mutation occurs when the addition or loss of DNA bases changes a gene's reading frame. A reading frame consists of groups of 3 bases that each code for one amino acid. A frameshift mutation shifts the grouping of these bases and changes the code for amino acids. The resulting protein is usually nonfunctional. Insertions, deletions, and duplications can all be frameshift mutations.
Repeat expansion
Nucleotide repeats are short DNA sequences that are repeated a number of times in a row. For example, a trinucleotide repeat is made up of 3-base-pair sequences, and a tetranucleotide repeat is made up of 4-base-pair sequences. A repeat expansion is a mutation that increases the number of times that the short DNA sequence is repeated. This type of mutation can cause the resulting protein to function improperly.
Answer:
skateboard b
Explanation:
p=mv
skateboard a
p=(60kg)(1.5m/s)=90kg*m/s
skateboard b
p=(50kg)(2m/s)=100kg*m/s
Answer:
<em>The mass of mercury = 0.136 kg</em>
Explanation:
Density: This is defined as the ratio of mass of a body and the volume of that body. The S.I unit of density is kg/m³. It can be represented mathematically as
D = m/v
m = D× v .......................... Equation 1
Where D = density of the mercury, m = mass of the mercury, v = volume of the mercury.
<em>Given: D = 13600 kg/m², v = 10 cm³ = (10×1/1000000) = 0.00001 m³</em>
<em>Substituting these values into equation 1,</em>
<em>m = 13600×0.00001</em>
<em>m = 0.136 kg.</em>
<em>Therefore the mass of mercury = 0.136 kg</em>
Force can be expressed as the time-rate change of momentum
Mathematically, Force = Change in momentum/change in time
Change in momentum = m(10.1-18.9) = -0.2024
Force = -2024/5.4 = -375N(approx)
The significance of the '-' sign is that the direction of force is the opposite that of the direction of our velocities since we assumed them to be positive.
Also this is the force on the ball, the force on the window will be equal and opposite.
