Answer:
Dish soap "cuts through grease" because it actually breaks down those greasy molecules. Now, the molecules that make the membranes around cells and the nucleus (which holds DNA) are lipids. So when dish soap is added, the cell membrane and the nuclei are broken apart, releasing the DNA.

Wind dispersion of reproductive cells allowed in seedplants to colonize
land away from water supplies. If water is needed to
passively transport gametes to each other and protect them from desiccation
plants were limited to densely inhabited space near water sources.
Bryophytes & ferns (seedless) are dependent on moist environments
for reproduction but the first seed plants developed an alternate
delivery system allowing independence from water- assisted reproduction.
Conifers produce pollen that can survive by carrying water and
nutrients along. Wind can now carry these male gametophytes to female
gametophytes under the scales of a cone. Fertilization produced a
diploid seed. The seed is protected and can survive dry conditions for a
period of time before growing. Pollen and seeds transferred a conifer’s
water dependence for their reproduction to wind dependence. </span>
Answer:
The state of gathering together.
Explanation:
Concentration is a noun and it refer to the act of gatthering closely or the state of gathering together or condition of collecting things or substances together.
In biochemistry it can mean the measure of the ratio of mass to volume in a solute and ratio of mass to volume of a solvent in a solution.
Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.
Answer:
λ = 37 nm
Radiation is in the ultra violet region.
Explanation:
Given data:
Energy of photon = 5.44 × 10 ⁻¹⁸ J
Wavelength of photon = ?
Solution:
E = h.c / λ
λ = h. c/ E
λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²
λ = 3.7 × 10⁻⁸ m
m to nm conversion.
λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m
λ = 37 nm
Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.
