Answer:

This question appears incomplete

Explanation:

This question appears incomplete, however Molybdenum-99 (⁹⁹Mo) is produced by bombarding Molybdenum-98 (⁹⁸Mo) with fast moving neutrons (¹₀n) as shown below

⁹⁸₄₂Mo + ¹₀n ⇒ ⁹⁹₄₂Mo + ⁰₀γ

This reaction is a nuclear caption reaction (which occurs in a nuclear reactor) for the production of Molybdenum-99 (⁹⁹Mo) which serves as a "precursor" for the production of medically viable/ Clinical Grade Technutium-99m (⁹⁹Tc) through Ion-exchange technique.

What is the relationship between DNA and mutation

Scrat [10]

Answer:

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation

A step-up transformer is connected to a generator that is delivering 141 V and 110 A. The ratio of the turns on the secondary to

hammer [34]

Answer:

31302 Volts and 55/111 Amps (≈0.5)

Explanation:

Secondary voltage / 141 = 1110 / 5

Secondary voltage = (1110*141) / 5

Secondary voltage = 31302

Amperage = 110/ (31302/141) = 55/111

Suppose that the moment of inertia of a skater with arms out and one leg extended is 3.0 kg⋅m2 and for arms and legs in is 0.90

babymother [125]

Answer:

Her angular speed (in rev/s) when her arms and one leg open outward is $1.56\frac{rev}{s}$

Explanation:

Initial moment of inertia when arms and legs in is $I_i=0.90 kg.m^{2}$

Final moment of inertia when her arms and on leg open outward, $I_f=3.0 kg.m^{2}$

Initial angular speed $w_i=5.2\frac{rev}{s}$

Let the final angular speed be $w_f$

Since external torque on her is zero so we can apply conservation of angular momentum

$\therefore L_f=L_i$

=> $I_fw_f=I_iw_i$

=> $w_f=\frac{I_iw_i}{I_f}=\frac{0.9\times5.2 }{3.0}\frac{rev}{s}=1.56\frac{rev}{s}$

Thus her angular speed (in rev/s) when her arms and one leg open outward is $1.56\frac{rev}{s}$

A Rac variant, in which the residue at position 61 was replaced with an alanine (Rac61A), was synthesized. Wild-type Rac and Rac

ludmilkaskok [199]

Answer:

Ammonia, $(NH_{3})$

Explanation:

If a Rac variant, in which the residue at position 61 was replaced with an alanine (Rac-61A), was synthesized. Also, Wild-type Rac and Rac-61A were incubated separately with VopC.

In order to obtain data to support that VopC modifies Rac at residue 61, the samples should be analyzed for the presence of Ammonia ( $NH_{3}[\tex]) compound.In chemistry, the Vanadyl Phthalocyanine (VopC) comprises of a catalytic domain that activates host cells GTPase Rac irreversibly, through the deamide side chain of the residue existing at position 61.Also, we know that a deamidation reaction gives off Ammonia, [tex](NH_{3})$ and as such when ammonia is present in the sample containing Wild-type Rac but not in Rac-61A, this simply proves or provide the data to support that VopC modifies Rac at residue 61.

<em>Additionally, deamidation can be defined as the chemical conversion (hydrolysis) of an amide functional group such as glutamine, asparagine, in a polypeptide to another functional group such as glutamic acid or isoaspartic acid respectively by treating it with a strong acid (deamidate, transamidase). </em>
