The use of restriction enzymes and electrophoresis to generate a map of the DNA molecule is known as RESTRICTION MAPPING. This technique is used to map an unknown fragment of DNA.

Restriction enzymes are enzymes that cut a DNA fragment at specific nucleotides sites, thereby generally smaller fragments of DNA.

Restriction mapping is a strategy used to map unknown fragments of DNA by digesting them into smaller fragments and then identifying the specific sites of the DNA breakpoints.

Restriction mapping can then be used to create a diagram of fragments of DNA marked with specific sites where they are cut by specific restriction enzymes.

Which of the following is an example of an adaptation that allows similar species to live in the same environment?

Andrei [34K]

Answer:

B. Both mussels and barnacles live in the tidal ecosystems.

Explanation:

Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.

Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.

As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.

__________ death rates and __________ infant mortality rates are due in large part to technological advances, improved sanitatio

Elis [28]

<h2>Both are Lower</h2>

Explanation:

Death rate is also known as Mortality rate.

Death rate is the ratio of total deaths to total population in a specific area or community over a specific time period.
Death rate = number of deaths/1000 of the population/year.
The death of young children under the age of 1 is known as Infant mortality rate.

The infant mortality rate (IMR) meausres the death toll which is the number of deaths of children under one year of age /1000 live births.

Luden [163]

Answer:

2.) Laws of Genetics

Explanation:

George Mendel has discovered the fundamental laws of Genetics or inheritance by working on his pea plant, Mendel founds that Genes come in pairs and they are inherited as specific units each one is different from parents.

Inheritance Genetics is when something is passed down from one generation to the next generation.

Mendel law of genetics are three types:

The Law of Segregation.
The Law of Independent Assortment.
The Law of Dominance.

Is DNA a like a single blueprint for the building of a house or like a book of blueprints

Travka [436]

I think it would be more like a book of blue prints because you have so much in your DNA like a book but one blue print just shows you one structure. <span />
