Answers
Answer:

Explanation:
Plants use nitrates as a supply of nitrogen, which is needed to make proteins for healthy growth. Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces.
Blue-white screening is a technique for the identification of___. It relies on the ability of____to cleave lactose. Blue-white tests take advantage of a molecule called____which is similar to lactose in that it is cleaved by B-galactosidase. When cleaved, the____(same as previous) turns . If uncleaved,meaning a non- function B-gal gene, the X-gal remains____. Therefore, a____bacterial colony means the B-galactosidase gene is not-functional, and therefore there____a recombinant gene inserted into the vector.
You’ve inserted a gene for pesticide resistance into your vector. To see if it was successful, you decide to conduct a blue-white screening test. But, uh-oh you are out of X-gal! You do notice some green Slime-gal sitting on the shelf and recall that this molecule works similarly to X-gal, but instead of turning blue when cleaved, it turns green when cleaved. You carry out the test, and find that all of your colonies are green! Was your insertion of the pesticide gene successful?
Answers
Answer:
Explanation:
Blue-white screening is a method for distinguishing proof of (recombinant bacteria). It depends on the capacity of ( B-galactosidase) to separate lactose. Blue-white tests exploit the molecule called (x-gel)_ which is like lactose in that it is severed by B-galactosidase. When separated, the (5-bromo-4-chloro-indoxyl) (same as past) turns _(_blue). In the event that uncleaved, which implies a non-function B-gal gene, the X-gal remains (white)_. Subsequently, a __(white) bacterial province implies the B-galactosidase gene isn't practical, and in this way there ___lacz__ a recombinant gene embedded into the vector.

Answer:d. liquid to solid
Explanation: Igneous rocks form when hot, liquid magma from inside the Earth cools and becomes solid. When this happens below ground, the rocks are called intrusive. When magma comes to the surface as lava and cools above ground, the rocks are called extrusive.

What is some evidence that makes plate tectonics is such a firmly believed idea?
Answers
Answer:
There are many shreds of evidence that support the theory of plate tectonics and make it such a firmly believed idea. These pieces of evidence include fossils, glaciers, earthquakes and volcanic activity, the shape of continents, the magnetism of rocks on the seafloor, the mid-ocean ridge system, and others.
Fossils give an idea of the location of the plants and animals that once existed. Earthquakes and volcanic activity also help in determining the cause of the boundaries and rifts formed. The shape of the continents seems to be fit with one other that gives the idea that these were together and moved away from each other.

On the planet Fugus, there is a species of flowers, Dontdrinkmycola, that has two special loci: Bach01 and Bach02. At Bach01, there are two alleles in the population: A (dominant) and a (recessive). Similarly, at locus Bach02, there are two alleles in the population: B (dominant) and b (recessive).
Individuals with the A_ genotype at Bach01 have mauve colored petals, and individuals with the aa genotype have teal colored petals. Likewise, individuals with the B_ genotype at Bach02 have mauve colored petals, and individuals with the bb genotype have teal colored petals.
In a cross between two doubly heterozygous Dontdrinkmycola flowers, the following number of offspring are produced: 280 offspring with mauve colored petals, and 220 teal-colored petals. The most likely form of epistasis here is:
a. Duplicate dominant epistasis.

Answer:
Explanation:
Refraction, on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.
A classic example of this would be the straw in a glass of water.
Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.
In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals

Answers
Answer:
Despite the hours of sunlight a city receives, the latitude of the city plays a larger role due to the fact that with a higher latitude, the higher the solar angle allowing a city to be much warmer.
Explanation:
A city that receives 10 hours more light each day has colder average temperatures because of the higher latitude of the city, the higher the solar angle allowing a city to be much warmer.
What do you mean by latitude?Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator.
These lines are known as parallels.
Thus, the higher latitude of the city, the higher the solar angle allowing a city to be much warmer due to which a city receives 10 hours more light each day.

Explanation:

All cells require a nitrogen source to grow. The preferred nitrogen source for E. coli is an ammonium salt (e.g. NH4Cl ). The NH 4 is assimilated into cellular metabolism by glutamine synthetase (GS), which catalyzes the synthesis of glutamine from glutamate, NH 4, and ATP. Glutamine then serves as a precursor to many compounds such as histidine, tryptophan, and nucleotides. These compounds control the activity of GS by feedback inhibition. Therefore, GS responds to changes in the nitrogen balance within cells. Identify the correct feedback inhibition mechanism that controls GS and its advantage for E. coli grown in a medium with a high histidine concentration. Assume that glucose and NH, are not limiting.
A. GS is controlled by concerted feedback inhibition. Histidine alone does not alleci GS. Therefore. E. coli growth will be unaffected.
B. GS is controlled by sequential feedback inhibition. Complete inhibition of GS by histidine will impair NH+ assimilation and impair E. coli growth.
C. GS is controlled by cumulative feedback inhibition. Therefore, histidine will inhibit GS partially. The remaining GS activity can support NH+, assimilation and E. coli growth.
D. GS is controlled by enzyme multiplicity. Only histidine-responsive GS will be shut down. The other GS isoforms will remain active to support E. coli growth.
Answers
Answer:
C.
Explanation:
The glutamine Synthetase of E. coli can collectively and totally be hindered and inhibited by various and numerous nitrogen-containing compounds like histidine, tryptophan, glycine, alanine, etc at optimum concentrations. But, individually at higher concentrations, these inhibitors can only inhibit the catalytic enzyme action partially. In this way, GS is constrained by total feedback restraint. Consequently, histidine will repress GS halfway. The excess GS movement can uphold NH+, absorption, and E. coli growth development.
