Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).

Answer:

Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:

The only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.

A forest area is being used for a new housing development. Most of the trees have been removed to make room for the
new houses. Predict the impact that this will have on the birds in the area.
The bird populations will stay the same because humans love birds.
The bird populations will decrease because humans see them as pests.
© The bird populations will increase because humans do not interfere with wild animals.
The bird populations will decrease due to competition for resources such as food and nesting sites.

1) Organisms reproduce either sexually or asexually. Asexual
reproduction is the reproductive process in which offspring have only

B) B&C
C) C&D
D) A,B, & C

What is the danger posed by introduced species? *
O Non-native species might have no natural predators in their new environment
Non-native species can occupy space and crowd out indigenous species
Non-native species might prey on native species threatening extinction
All of these are dangers posed by introduced species

The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? *

Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?

What two factors play a role in the type of snow flake created?

3. What things does your body do automatically to cool down or warm up?

How is Gypsy’s story related to psychology?

Brainliest Which of the following best explains how most plants grow? *


Plants store the excess oxygen they produce, resulting in them gaining mass

Plants store the excess glucose they produce, resulting in them gaining mass

Plants store the excess carbon dioxide they produce, resulting in them gaining mass

Plants store the excess water they produce, resulting in them gaining mass

There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
