Answer:
Photon radiation
A high-energy photon beam is by far the most common form of radiation used for cancer treatment. It is the same type of radiation that is used in x-ray machines, and comes from a radioactive source such as cobalt, cesium, or a machine called a linear accelerator (linac, for short).
The speed of radioactive particles is also an important factor in medical use. Beta particles travel very fast. This, combined with their small size, gives them significant penetrating power. In cancer treatment, for example, beams of beta particles can be created outside the patient's body and directed at tumors.

Answer:
llbb
Explanation:
<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
Answer:
Explanation:
Transportation in plants is an interesting process. It includes the transport of all the nutrients and water to all parts of the plant for its survival. In case of plants, the biggest concern is the transport of water and it terminates at the limiting factor depending on its growth. To overcome this problem, a tree uses several processes like Translocation, Storing, Absorption and Utilization of water
Definition of Transportation in plants
Transportation is the process of transporting water, minerals and food to all parts of the plant body.
Transport in plants occurs at three levels:
The uptake and release of water and solute by individual cells.
Short distance transport of substances from one cell to another.
Long distance transport of sap within xylem and phloem.Direction of transport is an important aspect in plants. In case of rooted plants, transport in xylem of both minerals and water is unidirectional from roots to stems. In this, mineral and organic nutrients undergo multidirectional transport. It includes the organic compounds that are formed during photosynthesis are exported to all parts of the plants along with storage organs. Plant growth regulators, hormones and chemical stimuli are also transported in unidirectional or polarized manner, in very small amounts, from where they are formed to other parts
