All of the following are ways in which DNA technology plays a role in medicine except identifying mutations. Producing insulin and growth hormone. Tracking how a condition is passed between generations. Examining paternity.
DNA technology plays a role in medicine except identifying mutations when EXAMINING paternity. It involves the determination of the biological father.
DNA technologies refer to the genetic engineering techniques used in medicine and biotechnology for diverse purposes.
For example, DNA recombinant technologies can be used to produce insulin, which is a hormone required for the treatment of individuals suffering from diabetes.
DNA paternity tests are genetic tests whose objective is to determine nucleotide (DNA) polymorphisms and thus indicate whether a man is another individual's biological father.

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 is something your community can try to reduce the environmental impact of
salting? Select ALL that apply.
A)
Buy more snow plows and use less salt.
B)
Ban all salt based solutions in the state.
C)
Provide incentives to consumers who install snow tires for increased
traction.
D)
Provide tax incentives to municipalities who will install solar panels that
heat water in pipes embedded in the road.
Wet the pavement before applying brine solutions to help the salt adhere
to the road, cutting back on how much they use.

what conditions prompt hemoglobin to release oxygen? select the three answers that are correct.
The conditions that prompt hemoglobin to release oxygen are:
Decrease in pH (high acidity)ExerciseUnloading of oxygen from haemoglobinHaemoglobin is the blood protein that is used to carry oxygen in our body and gives blood its red colour. The ability of this protein to carry oxygen depends on some factor. These factors include:
Decreased pH: Upon the production of carbondioxide in the tissue cells, carbonic acid is produced which leads to decrease in pH of the blood. Exercise: During exercise, the temperature of muscle increases secondary to its utilisation. This will cause the release of unloading of oxygen from haemoglobin.Therefore, conditions that prompt hemoglobin to release oxygen are decrease in pH (high acidity) and exercise.

O
B. 40 grasshoppers/20 square meters
O C. 1 grasshopper/1 square meter
O D. 50 grasshoppers/30 square meters
35 grasshoppers/10 square meters has the highest population density.
The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density. In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.

Answer:
It acts as a catalyst to break down harmful bacteria.
Explanation:
The bacterial cell was is made up of murein also called peptidoglycan. The active site of the enzyme lysozyme binds with the molecule of peptidoglycan attacking and breaking it. It degenerates the bacterial cell wall eventually killing the bacteria.Lysozyme mostly, works on the gram-positive bacteria as the peptidoglycan layer is present on the outer side of the cell wall unlike gram-negative where it is present in the inner side of the cell wall. Thus, acting and functioning as a catalyst that breaks down walls of bacteria, enhances innate immunity, and protects from infection.For more information:

Onion root cell 3 is the closest to the completion of the cell cycle. Mitosis is
the type of cell division which involves the production of two identical
daughter cells.
Telophase is regarded as the final stage of mitosis before cytokinesis takes
place. In this phase, the chromosomes decondense and the spindle breaks
down.
There is also formation of two new nuclei of the daughter cells which are
separated by the newly formed nuclear membrane which is evident in the
onion root cell 3 thus making it the most appropriate choice.
