3. Use the Venn diagram to show the similarities and differences of the five and six kingdoms |
|
Answer» Answer: Five KINGDOM CLASSIFICATION Very early on, scientists began grouping the living organisms under different categories. Some biologists CLASSIFIED organisms into plants and animals. Ernst Haeckel, Robert Whittaker, and Carl Woese are some biologists who attempted a broader system of classification. Amongst these, the Five Kingdom Classification proposed by Robert Whittaker stood out and is widely used. Whitaker proposed that organisms should be BROADLY divided into kingdoms, based on certain characters like the structure of the cell, mode of nutrition, the source of nutrition, interrelationship, body organization, and reproduction. According to this system, there are five MAIN kingdoms. They are: Kingdom Monera Kingdom Protista Kingdom Fungi Kingdom Animalia Kingdom Plantae Kingdoms are divided into subgroups at various levels. The following flowchart shows the hierarchy of classification. Kingdom → Phylum → Class → Order → Family → Genus → Species Five Kingdom Classification (Source: Wikipedia) Explanation: |

Can someone please answer these? The answers are short. I'll mark brainliest if everything makes sense1. The ability to roll your tongue is an autosomal dominant trait. John can’t roll his tongue. Maria can roll her tongue. They have a child who is a non-roller. (.5 pt) What is the genotype ratio for the possible offspring in the TT : Tt : tt form? (.5) What is the phenotype ratio in Roller:non-roller format? (.5) What is John’s genotype? (.5) What is Maria’s genotype? |
Answer» (1) Answertand in front of a mirror, open your mouth slightly and try to bring the sides of your tongue up towards each other to make a U-shape. If you can do it you are a tongue-roller, along with between 65 and 81% of people, more of them women than men. and in front of a mirror, open your mouth slightly and try to bring the sides of your tongue up towards each other to make a U-shape. If you can do it you are a tongue-roller, along with between 65 and 81% of people, more of them women than men.If you tried this before, the chances are it was in a biology lesson on genetics at school. I remember SITTING on my high stool at the lab bench trying in vain to roll my tongue, while my friends seemed to be able to do it effortlessly. The reason we couldn’t all do it, we were told, is because it is a simple genetic trait. You had EITHER inherited the right variant of the tongue-rolling gene or you hadn’t. And if you hadn’t, you would never be able to do it (2) AnswerTt X tt = Tt, Tt, tt, and tt. The genotypic ratio for this cross is 1:1 and the phenotypic ratio is 1:1, where Tt is heterozygous dominant and tt is heterozygous recessive. This type of cross is a test cross. Additional Information: The test cross takes place between dominant and recessive alleles. (3) AnswerHumans have a diploid number of 46 (46 CHROMOSOMES). Our chromosomes come in pairs called homologous pairs. Each chromosome has similar genes in similar places, though the variety of each gene may be different. The variety of gene is known as an allele. We get one chromosome in the pair from each parent, so we INHERIT 23 chromosomes from each parent. (4) AnswerJohn's genotype is IBi and his phenotype is type B blood. (5) AnswerFrom the XEXe genotype, we can deduce that Maria is heterozygous for this gene, given that she has two different alleles (E and e). From the XEXe genotype, we can deduce that Maria is heterozygous for this gene, given that she has two different alleles (E and e).The allele e does not express itself in Maria because it is recessive (it is in miniscule). It is expressed only in case of homozygosity for this allele. Maria will express the E allele by the principle of the dominance of the alleles. hope this helps fullby nivaskumar |
