Briefly explain how DNA profiling is used to identify individuals.

Answers

Answer 1
A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.

Ava has been reading about the interactions among the components of the Earth. This group of components work together to make a system.

The group of components of the Earth work together to make an environment we live in.

What are the different components of the Earth?

The interactions between Earth's five systems—the geosphere, biosphere, cryosphere, hydrosphere, and atmosphere—create the environment we are accustomed to.

The Earth's interior and surface, which are both formed of rocks, make up the first system, the geosphere. The second system is made up of the little area of the planet that may sustain life; this area is known as the biosphere. The third system contains the hydrosphere, or regions of Earth that are completely covered with water. The fourth system is the atmosphere, a gaseous envelope that maintains the planet's temperature while also supplying carbon dioxide for photosynthesis and oxygen for breathing. The cryosphere, which is composed of enormous amounts of ice in the poles and elsewhere, is the fifth system. The maintenance of the Earth as we know it depends on the interaction of all five of these vast and intricate systems.

The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on approximately 8300 lane miles of Maine’s state roads. They usually plan on an average of about 30 treatable events in a winter. This includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative effects on plant life and aquatic ecosystems. What are the environmental effects of salting that must be mitigated? Select ALL that apply.A) Salt kills roadside plants. B) Salt builds up in roadside soil , changing its pH, preventing the growth of plants. C) Salt corrodes metals like automobile brake linings, frames, and bumpers, and can cause cosmetic corrosion.

The types of salt used for road salting include:

rock salt,

salt brine,

winter sand,

a mix of sand and salt.

The impact of road salting on the environment include the following:

Decrease in reproduction and growth of plants: This is because increase salinity are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Negative effect on aquatic ecosystems: This affects mostly the freshwater ecosystems as high levels of salt are very toxic to the aquatic organisms.

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

Hebrews 11:7

Answers

Answer:

Faith, according to the Bible, is not blind. More than half of the verses in the book of Hebrews are dedicated to explaining reasons and evidence to accept the new covenant in Jesus Christ. Nor is faith gullible, or senseless. Instead, godly faith is exemplified by trust. That trust is based on what we know of God, relying on Him for the things we do not know. In particular, godly faith looks forward, from an eternal perspective, and produces obedience, even in the face of hardship. God takes what we cannot see, or cannot understand, and uses it to make good on His word. Since faith relies on what we've seen of God, and trusts Him for the future, it becomes the "assurance of things hoped for, the conviction of things not seen" (Hebrews 11:1–3).
