Answer:
Explanation:
Membrane bound organelles and eukaryotic
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
Answer:
<u>Option -</u> An open circulatory system inside the adults.
Explanation:
- A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature <u>an open circulatory system</u>.
- Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.
Answer:
a. Trisomic
Explanation:
A trisomy is a genomic phenomenon whereby a particular chromosome is present in three copies. In this case, the trisomy involves the chromosome P, being this species a tetraploid with 5 pairs of homologous chromosomes (2n = 10). In humans, the trisomy for chromosome 21 is one of the most common types of aneuploidies that lead to the Down syndrome by producing alterations in gene expression patterns that are associated with changes in the phenotype
The right answer is C.
A genetic disease is called autosomal dominant transmission when
:
* The morbid allele ("sick" version, mutated of the gene in question) is on a non-sexual chromosome (neither X nor Y).
* The presence of a single morbid allele is sufficient for the disease to express itself.
The morbid allele is transmitted by either the father or the mother (or both, if they have the same inherited autosomal dominant genetic disease). Anyone with one of their affected parents is affected.
Jackson-Weiss syndrome is indeed an autosomal dominant disease characterized by a malformation of the feet, craniosynostosis of varying degrees, facial abnormalities, enlargement of the big toes and normal hands.
