Answer:
The correct answer is "a well-developed notochord".
Explanation:
The missing options for this question are:
A) paired fins
B) jaws
C) a well-developed notochord
D) a rasping tongue
The correct answer is option C) "a well-developed notochord".
Lampreys and hagfishes are two species of jawless fish that are uncommon to see, but they have more than 30 different species for each one of them. Both lampreys and hagfishes have a well-developed notochord, during their larvae and adult forms. The notochord provides support to their body as it has the function of a cartilaginous skeleton.
It shows how individuals within a family are related to each other. We can also indicate which individuals have a particular trait or genetic condition. If we take a pedigree, which we usually try to include at least three generations, we might be able to determine how a particular trait is inherited.
By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant, recessive, autosomal, or sex-linked.
An animal is considered to have a good pedigree when all its known ancestors are of the same type. 60 percent of dogs and ten percent of cats have pedigrees. 2. countable noun. Someone's pedigree is their background or their ancestors.
In medical genetics and other medical fields, a proband, proposito (male proband), or proposita (female proband) is a particular subject (person or animal) being studied or reported on. On pedigrees, the proband is noted with a square (male) or circle (female) shaded accordingly.
Pedigrees are drawn using standard symbols and formatting. Males are represented by squares and females by circles. Individuals who are deceased have a slash through the symbol representing them. Symbols for individuals affected by a particular disorder are shaded.
Scientists have devised another approach, called pedigree analysis, to study the inheritance of genes in humans. ... Once phenotypic data is collected from several generations and the pedigree is drawn, careful analysis will allow you to determine whether the trait is dominant or recessive.
Pedigree analysis is done in the study of human genetics because control crosses cannot be possible in human being and age of human is more. Pedigree analysis can be used to trace the inheritance of a specific trait abnormality or disease.

Answer:
Cell membrane present, ribosome present, lysosomes present, nuclear membrane present: Animals
Cell wall present, ribosomes present, nuclear membrane absent: Prokaryotic
Cell wall present, ribosome present, nucleus present, large vacuole present: Plants
Reproduces inside a cell, Nucleus absent, RNA present : Virus
Explanation:
Animals are multicellular organisms which do not possess cell wall. Hence option 1 represent animals.
Prokaryotes have cell wall but lack nuclear membrane. Hence, option 2 represents prokaryotes.
Plant cells have a cell wall, a nuclear membrane as well as a large nucleus. Hence option 3 is plants.
Population distribution pattern do US residents most closely resemble is clumped dispersion.
<h3>Which population distribution pattern do US residents most closely resemble? </h3>
Clumped dispersion is the population distribution pattern present in the US residents. Clumped dispersion is the most common pattern that occurs due to an uneven distribution of resources in the environment. That region where more resources are present, the population density is higher and vice versa.
So we can conclude that population distribution pattern do US residents most closely resemble is clumped dispersion.
