Answer: Weak.

Explanation:

The complete question is:

Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?

Well, here we have beta decay.

Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)

Then the correct option is the second one, weak.

<h2>T4 protein and T4 DNA</h2>

Explanation:

A bacteriophage is an infection that attacks bacteria. At the point when the tail strands identify an objective host the bacteriophage to the cell, injected its DNA, and utilizations the microscopic organisms' apparatus to reproduce.
T4 is a sort of bacteriophage that infects of E. coli.
The bacteriophage T4 capsid is a prolonged icosahedron, 120 nm long and 86 nm wide, and is worked with three essential proteins such as gp23*, which shapes the hexagonal capsid cross section, gp24*, which structures pentamers at eleven of the twelve vertices.
gp20, which frames the extraordinary dodecameric entry vertex through which DNA.
T4 DNA Ligase is ligation catalyst which utilized the parts of DNA by the catalyzing between compared 5'phosphate and 3' hydroxyl ends and phosphodiester bonds in the double stranded DNA utilizing ATP as a coenzyme.

allochka39001 [22]

Answer:

The correct answer is - c) Pathology.

Explanation:

Mycology is the branch of biology in which students study fungi and their characteristics including their biochemistry, taxonomy, and genetics.

Agronomy is the other branch of biology that deals with agriculture and its practices and work to improve the crops.

Phycology is the study of algae and their characteristics including their biochemistry, taxonomy, and genetics.

The disease and its causes are studied under the pathology branch o biology therefore, red rust would be studying in this discipline.
