Answer:
All are methods to separate mixtures
Explanation:
A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
Hence, all the methods listed are used to separate mixtures.

I am 100% sure that the correct Answer is:
Convection current
Please do have a great rest of your day!
The cycle that powers the ocean currents, weather, and tectonic plates it called convection current. The correct option is d.
What is convection current?Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.
Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.
Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.
Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.
Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.
Thus, the correct option is d.

In a certain plant, yellow leaves are dominant (Y) and red leaves are recessive yA plant with genotype Yy and a plant with YY are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint. Draw a Punnett square to help you determine the answer) OA. 0 OB. 3 Oc. 1 OD. 2
Answer:
Its 1 I just took the test and answered 0 and got it wrong
Explanation:
If two plants with yellow leaves with YY and Yy genotypes are crossed then all the offspring will have yellow leaves. Thus, the correct option is A.
What is a Monohybrid cross?A monohybrid cross is the hybrid of the two individuals with homozygous genotypes or heterozygous genotypes which result in the formation of opposite phenotype for a certain genetic trait. The cross between the two monohybrid traits such as flower color or plant height is called a Monohybrid Cross.
When two plants, one with homozygous yellow leaves (YY) and one with heterozygous yellow leaves (Yy) are crossed, then the offspring will have yellow leaves and none of the offspring will have red colored leaves as this is a recessive trait and it requires to be present in homozygous condition to show its effect.
Therefore, the correct option is A.

What was known before Franklin and Wilkins conducted their studies of DNA? Select three options.
DNA is found in the nucleus of a cell.
The human genetic code is made of 50,000 genes.
Organisms store and transmit genetic information.
DNA has a double-helix structure.
Cells contain protein molecules.
The correct answer will be-
1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.
Explanation:
The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.
Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.
Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.
DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.
Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.
Thus, 1. DNA is found in the nucleus of a cell
2. Organisms store and transmit genetic information
3. Cells contain protein molecules.
