Why is it important to avoid planting the same crop in the same field year after year

1 answer:

6 0

Planting the same crop in the same place each year zaps nutrients from the earth and leaves soil weak and unable to support healthy plant growth. Because soil structure and quality is so poor, farmers are forced to use chemical fertilizers to encourage plant growth and fruit production.

s2008m [1.1K]

The options attached to the above question are given below:

A) The boys at first were very polite about my medals and asked me what I had done to get them.

B) I showed them the papers which were written in very beautiful language of full of fratellanza and abnegazione but which really said with the adjectives removed that I had been given the medals because I was an American.

C) after that their manner change a little toward me although I was their friend against Outsiders

D) I was afraid but I was never really one of them after they had read the citation because it had been different with them and they had done very different things to get their medals.

E) I had been wounded it was true but we all knew being wounded after all was really an accident.

ANSWER

The correct option is D.

In the statement given in option D, it can be seen that the speaker was formerly a soldier, who had fought in a war and had been awarded a medal to that effect. But despite knowing about this meritorious service that he had rendered to his country and the award he was given, he was not really accepted as an inner person by the group of people that was refereed to in the statement. They did not think much of him.

Haase D, Germing U, Schanz J, et al. New insights into the prognostic impact of the karyotype in MDS and correlation with subtyp

vivado [14]

We have produced a huge, novel data set that incorporates morphologic, clinical, cytogenetic, and follow-up information from 2124 patients with myelodysplastic conditions (MDSs) at 4 organizations in Austria and 4 in Germany. Cytogenetic examinations were effectively acted in 2072 (97.6%) patients, uncovering clonal anomalies in 1084 (52.3%) patients.

Numeric and underlying chromosomal irregularities were reported for every patient and partitioned further as indicated by the quantity of extra anomalies. Along these lines, 684 unique cytogenetic classes were distinguished. The effect of the karyotype on the normal flow of the illness was concentrated on in 1286 patients treated with steady consideration as it were.

Middle endurance was 53.4 months for patients with ordinary karyotypes (n = 612) and 8.7 months for those with complex inconsistencies (n = 166). A sum of 13 uncommon irregularities were related to great (+1/+1q, t(1q), t(7q), del(9q), del(12p), chromosome 15 inconsistencies, t(17q), monosomy 21, trisomy 21, and - X), middle (del(11q), chromosome 19 peculiarities), or poor (t(5q)) prognostic effect, separately.

The prognostic significance of extra anomalies differed significantly relying upon the chromosomes impacted. For all World Health Organization (WHO) and French-American-British (FAB) order framework subtypes, the karyotype gave extra prognostic data. Our examinations offer new experiences into the prognostic meaning of uncommon chromosomal irregularities and explicit karyotypic mixes in MDS.

The syntenic genes A and Z are linked. A cross between two parents, AAZZ and aazz, produces F1 progeny with the AaZz genotype. W

garik1379 [7]

Answer:

The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Explanation:

The genotype of F1 progeny is AaZz

The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"

Thus, total four allele pairs will be formed.

First allele pair would be - AZ

Second allele pair would be - Az

Third allele pair would be - aZ

Fourth allele pair would be - az

Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az

Answer:

Oxygen produced during light reaction of photosynthesis is partially consumed during cellular respiration by plants and unconsumed oxygen is released in atmosphere. Thus plants produce oxygen in presence of light.
