Which of the following organs does a dog not have? spleen appendix gallbladder large intestine.

Answers

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.

Answers

Answer:

the third one

Explanation:

The definition for natural selection is "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution. Compare with survival of the fittest (see survival)."

The third question shows us natural selection. Because the population of black mice went up and the tan mice went down. this is an example of natural selection because the black mice have adapted to their environment and reproduced while the tan mice have not.

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?

Answers

Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.

Mutation

This 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.

The antiparallel nature of the DNA double helix is responsible for the opposing direction of replication.

DNA replication

The 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.

Alice Paul learned how to use this aggressive approach in England and brought it to the United States. For a while, she held a leadership position with the National American Woman Suffrage Association. She helped organize the March on Washington held on March 2, 1913, the day before President Wilson's inauguration. The parade was led by a human rights lawyer riding a white horse, and behind her women marched in costumes reflecting the nations that had already given women the vote. Multiple floats, bands, brigades, and costumed women paraded on through Washington, D.C. However, during the parade of protest, some men attacked the women and behaved poorly, and the police did nothing to stop it. The actions of the men led to an inquiry, which brought women's suffrage significant public awareness. However, some women did not agree with Paul's methods. Paul ultimately formed a separate group, which became known as the National Woman's Party. This group of women held marches and hunger strikes. They were also the first organization to organize a picket of the White House in January 1917. While their choice to picket during World War I angered some, their methods did make an impact and paved the way for women's suffrage to become law.Both peaceful and aggressive approaches contributed to the ratification of the 19th Amendment on August 18, 1920. On November 2, women across the nation voted, which marked the beginning of the ongoing struggle to reform the rights of women in the United States.Read the sentence from the text:On November 2, women across the nation voted, which marked the beginning of the ongoing struggle to reform the rights of women in the United States.Which point does this piece of evidence support?Alice Paul learned how to use this aggressive approach in England and brought it to the United States.Multiple floats, bands, brigades, and costumed women paraded on through Washington, D.C.Peaceful and aggressive approaches contributed to the ratification of the 19th Amendment on August 18, 1920.Paul ultimately formed a separate group, which became known as the National Woman's Party. true or false? most calico cats are females due to genetics? 24.
