Due to the antiparallel nature of the dna double helix, _________.
The antiparallel nature of the DNA double helix is responsible for the opposing direction of replication.
DNA replicationThe DNA is made up of two strands that are antiparallel to each other. One is in a 5' to 3' direction while the other is in a 3' to 5' direction.
The replication process can only proceed in 5' to 3' direction only.
Consequently, one strand at a replication fork is synthesized in the direction of the fork, while the other is synthesized in the opposite direction away from the fork.

Which of the following organs does a dog not have? spleen appendix gallbladder large intestine.
Answer:
Surprisingly, dog don't have an Appendix
Explanation:
Does this help?
The cecum, a part of the large intestine, is attached to the appendix, which is a small, finger-like pouch. Dogs, along with many other animals, do not have an appendix, although humans do.
In humans, the appendix is thought to have some minor immune system activities and may help with digestion. It is a vestigial organ, meaning that it has lost or reduced its original role over evolution, and its specific function is not fully understood. Dogs do not have an appendix because their digestive systems have different adaptations. Dogs have a digestive system that is relatively short and designed to break down animal proteins.
Therefore, the correct option is B.

Animalia has complex organ systems and Fungi do not.
Fungi are heterotrophic organisms with a chitinous cell wall. The fungal frame is fabricated from thread-like lengthy systems referred to as hyphae. Many hyphae collectively make an entangled shape referred to as mycelium.
Hence, fungi showcase the tissue stage of frame organization animals are heterotrophic organisms and do not use a cell wall around their cells. They showcase the organ machine stage of frame organization, this is to say, that they have got numerous organ structures of their frame to carry out distinct functions.

Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though the animals were genetically identical and shared the same mother, they showed variations in their phenotypes that were beyond the normal range in expression.
Based upon today’s knowledge of genetics, which explanation describes the most likely cause of the phenotypic variations?
Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.
MutationThis refers to a sudden change to the DNA sequence of living organisms.
When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.
For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.
In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.
