Answer:
restriction enzymes are enzymatic proteins which cleave DNA at specific sites. these proteins are contained inside the bacteria to cleave the foreign DNA particles from Bacteriophages. these enzymes can be isolated from the bacteria and can be used in vitro for DNA manipulation.
Explanation:
restriction enzymes cut DNA creating smaller segments.
Also name restriction endonucleases
examples:
HIND3, BAMH1, ECOR1, etc
In humans, if a non-disjunction event led to an individual with a genotype of XXY, they would be male because they have a Y chromosome.
<h3>What are X and Y chromosomes?</h3>
The X chromosome and Y chromosome are homo-logous chromosomes that determine the se_x in mammals.
The presence of the Y chromosome is indicative of the males, whereas two X chromosomes are females in normal conditions.
Non-disjuntion refers to the faulty separation of homo-logous chromosomes during meiosis.

Answer:
Each and Every species in ecosystem are interlinked their behaviour,mode of getting their food and the uses of natural resouces is known as functional diversity
Explanation:
Biodiversity explains the intensity of an ecosystem in terms of species,food resources and genetically varied species. The levels of biodiversity are several, and each level denotes how different the species genetically and phenotypically,their behaviour, and their mode of food resources in a particular region. The main components of biodiversity are Species diversity,Genetic diversity,Ecosystem diversity and Functional diversity.
Generally species rich ecosystem have high functional diversity because there many species with different behaviours and different mode of food consumption Functional diversity is one of the components of biodiversity it comprises the characters of microbes widespread in an ecosystem.Functional diversity is highly important because of it stability and and nutrient availability to the species. It can be measured by its richness and evenness.
1. Richness: It refers to the dwelling of number of species in a specific niche
2. Evenness: It refers to the organisms in a particular nich how they are evenly distributed
Knowledge about a particular ecosystem reveals its richness and evenness and it provides an individual to know about the diversity of functional characters in an ecosystem
