Cryogens and dry ice are cryogenic substances that cause skin related problems if not handled carefully. These are extremely dangerous to touch and cause boiling of skin. The skin is severely damages if touched with naked hands.
Care should be taken while handling cryogens Use of specific gloves and personal protective equipments to cover yourself.
Answer: FALSE
Answer:
<h3>Heyy mate!</h3>
Explanation:
- (i) The gravitational force between two objects is directly proportional to the product of masses of the two objects. So, if the mass of one of the objects is doubled, then the force also gets doubled (it becomes 2 times).
- If the mass of one of the objects is doubled, then the force of gravity between them is doubled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
- The distance between the objects is doubled and tripled
- Force thus becomes one-fourth of its initial force. Force thus becomes one-ninth of its initial force.
- Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. ... If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Answer: D. 100%
Explanation:
One parent is with is a true breeding blue flowering plants this means the two alleles of the genotype are homozygous dominant alleles (BB).
The other parent is a true breeding with flowering plant, this means the two alleles of the genotype are homozygous recessive alleles (BB).
When both parents are crossed, the possible genotype outcome is
B B * b b
Bb Bb Bb Bb
Therefore since the blue flowering plant allele (B) is dominant to the white flowering plant allele (b) the probability of an offspring outcome to be a blue flowering plant is 4/4 which is 100%.44
Answer is 100%

Answer:
snowflake is a single ice crystal that has achieved a sufficient size, and may have amalgamated with others, then falls through the Earth's atmosphere as snow.Each flake nucleates around a dust particle in supersaturated air masses by attracting supercooled cloud water droplets, which freeze and accrete in crystal form. Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants.
The main constituent shapes for ice crystals, from which combinations may occur, are needle, column, plate, and rime. Snow appears white in color despite being made of clear ice. This is due to diffuse reflection of the whole spectrum of light by the small crystal facets of the snowflakes
