alisha [4.7K]

Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.

Translocation can happen due to many reasons like:

A) Some of the changes that arise around the time of conception or production of sperm or egg.

B) The inheritance of altered chromosome from father or mother.

Translocations can be divided into two forms:

Reciprocal translocation
Robertsonian translocation.

In reciprocal translocations, fragments of two chromosomes break off from two different places, break and swap each other's segments. While in Robertsonian translocation one chromosome attached with other.

Answer:

A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

You have ligaments around your knees, ankles, elbows, shoulders, and all of your other joints.

Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. Ligaments are made out of connective tissue that has a lot of strong collagen fibers in it. They are found in different shapes and sizes in the body. Some look like pieces of string, others look like narrow or wide bands. There are arch-shaped ligaments, too.

What happens to a potassium atoms electrons when it becomes an ion?

Scrat [10]

The alkali metals in group l of the periodic table all have a single electron in the outermost shell. These metals form covalent bonds with for example the halogens, which have 7 electrons in their outer shell.
When the alkali metal halide, such as KCl is dissolved in water, it dissociates into ions. The K atom loses the single electron, and therefore has a positive charge. In turn, the chloride atom gains the electron and becomes the negatively charged chloride ion.
