The answer is that the criteria of classification change whith the improved understanding of organisms around us
larisa86 [58]3 years ago
4 0

Answer:

Classification for organisms is constantly changing because our technology is getting better. Classification used to be based on how similarly organisms appeared (morphological data). However, with better technology, we are able to look at the DNA of different species and are finding that the organisms we once thought to be closely related are not. Additionally, organisms we once thought to be distantly related may have very similar DNA.

Our classification now is based off of evolutionary history or phylogeny. Since evolution is so closely linked with genetics, our classification usually changes with new discoveries in DNA.

Traits controlled by organellar dna do not show mendelian inheritance because
Lapatulllka [165]

Answer:

In mendelian inheritance, the alleles for a gene show normal dominant-recessive relationship. Chromosomes also show crossover due to which new random combination of traits is possible in the offspring. This crossover takes place between homologous chromosomes during meiosis I.

Organellar DNA like the ones present in mitochondria and chloroplast do not follow mendelian inheritance because unlike nuclear chromosomes they do not have cross over events. There is no orderly segregation of alleles during meiosis. Traits controlled by them are usually inherited as it is and usually it is from the maternal parent because paternal gamete like sperm does not contain mitochondria.

A school nurse is assessing children in the third grade for pediculosis capitis. what assessments should be made?
GarryVolchara [31]
Pediculosis capitis, also known as hair lice, is one of the most common of ectoparasitic infections. This is highly contagious, especially in schools, day care centers, or areas wherein children are in close contact with infected children. In this case, the nurse should examine the heads of the children for small lice or nits on the hair shafts.

Why don't hybrids reproduce
nordsb [41]
An animal category is a gathering of creatures that can breed together that can deliver fruitful prosperity. 

Ligers, Mules, They aren't species, they are a mix of 2 animal groups subsequently the name is half and half, they can't recreate in light of the fact that, the two distinct species have two unique quantities of chromosomes. Species can duplicate inside of their own species, since every person inside of the species has the same number of chromosomes.

The crossover's can't imitate in light of the fact that sex cells would never be prepared as their chromosomes would not be right. The half breeds would never  happen in nature, they were made by man, I don't know how they fulfilled this, yet, at any rate, thats why the mixtures can't replicate.
