<span>To determine if a measurement is authentic, you can check whether the measurement makes sense in the context of whatever is being measured. If a measurement is physically impossible, then it is not authentic. If a measurement is inconsistent or far off from multiple repeated measurements of the same kind, then it is not likely to be authentic, so you could test the authenticity by repeating the measurements.</span>
Answer:
The correct answer is ''aids in the passive movement of water out of the tubule''
Explanation:
The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
