Answer:
largest of the three, positive charge, inside nucleus
Explanation:
One way a farmer could increase the amount of available nitrogen in his fields without adding synthetic fertilizer would be to grow a legume crop to support the development of root nodules.
Answer:
1. A plant of genotype
is testcrossed to
If the two loci are 10 m.u. apart, what proportion of progeny will be A B/a b?
45 percent of the progeny will be A B/a b
2. The A locus and the D locus are so tightly linked that no recombination is ever observed between them. If A d/A d is crossed to a D/a D, and the F1 is intercrossed, what phenotypes will be seen in the F2 and in what proportions?
P A d/A d × a D/a D
F1 A d/a D
F2 1 A d/A d
2 A d/a D
1 a D/a D
3. The R and S loci are 35 m.u. apart. If a plant of genotype
is selfed, what progeny phenotypes will be seen and in what proportions?
4. The cross E/E · F/F × e/e · f/f is made, and the F1 is then backcrossed to the recessive parent. The progeny genotypes are inferred from the phenotypes. The progeny genotypes, written as the gametic contributions of the heterozygous parent, are in the following proportions:
Explain these results.
The two genes are 33.3 map units (m.u.) apart.
5. A strain of Neurospora with the genotype H · I is crossed with a strain with the genotype h · i. Half the progeny are H · I, and half are h · i. Explain how this is possible.
Because only parental types were recovered, the two genes must be quite close to each other, making recombination quite rare.
Explanation:
The individual bacteria would appear larger under the magnification of 40X. Thus, the correct option is A.
<h3>What is Magnification?</h3>
Magnification may be defined as the power of a microscope to deliver an image of an entity at a scale larger and sometimes smaller than its genuine size.
Bacillus subtilis is a distinct germ, that is rod-shaped in structure and is Gram-positive. Under the 40X microscope, it looks as rough, opaque, fuzzy white, or narrowly yellow with irregular edges.
The size of the entity or any object under the microscope of 40X magnification is 5mm, while the of the entity or any object under the microscope of 10X magnification is 1-2mm.
Therefore, it is well described above.
