The answer is phylum Sarcodina and class Heliozoa.
<span>Actionophryx belongs to the group of Sarcodina. However, this is an older classification, and it is known that it belong to the groups of amoebas. It has a spherical body (helios, greek for sun) with axopodia (arms) so it is classified to the class sun-animalcules or Heliozoa. The body is surrounded by a glassy silica shell. It lives in freshwater, but some species are found in seas and oceans. </span>
Answer:
The autosomal trait are present on the autosomes and does not have any influence on the sex of the organism. Two main types of autosomal trait are autosomal dominant and autosomal recessive trait.
a. The trait discussed in the question must be the autosomal dominant trait. As the normal and affected children are produced by the affected parents cross. The appearance of the normal child determines that the trait is dominant.
b. Since both the parent are affected but the normal child has been produced from the cross. The parents must be heterozygotes for the trait, (Aa). Their cross will produce the progeny AA, Aa and Aa (affected) and aa (normal).
What specific traits go with each letter? Also which traits are dominant and which are recessive ?
Darwin used Multiple lines of evidence to support the theory of evolution by natural selection they are fossil evidence, biographical evidence and anatomical evidence.
Explanation:
The Multiple types of evidences supports the theory of evolution. The homologous structures provides the evidence for common ancestry and the analogous structures describes that similar selective pressures can produce similar adaptions.
Evolution by natural selection is one of the good method in theory of history of science and it is supported by evidence from wide variety of scientific disciplines.
The comparative sequence analysis method is used to examine the relationship between the DNA sequences of different species. This evolutionary relationships are used in the study of diseases like HIV.
