Answer:

The right answer is B.

Eukaryotic cells are much larger than prokaryotic cells. Their volume is one thousand to ten thousand times greater. They contain a nucleus surrounded by a membrane and the DNA is divided into chromosomes that undergo mitosis during cell division. The cytoplasm contains numerous membrane-bound organelles such as mitochondria, chloroplasts, the Golgi apparatus, the endoplasmic reticulum. Each organelle performs a particular function.

When you hear the term mutation, you usually think of change. But how do mutations influence traits that may be inherited?
lana [24]

Hereditary mutation - may be passed to another generation, occurs in gametes, variation that may enhance survival.

Somatic mutation - not passed from generation to generations, occurs in body cells.

Both- changes in DNA.

<h3><u>Explanation:</u></h3>

Mutations are defined as sudden changes in DNA that takes place by changing a particular nucleotide or a portion of DNA, or even a whole chromosome which has potential to change characters of an organism. Mutation was first proposed by Hugo de Vries who is also known as the Father of Mutation Theory.

Mutations can occur in any cell of body. It may occur in somatic cells, or in germ mother cells. But the mutations that occur in germ mother cells are actually the mutations that are carried forward by the gametes into next generations. Mutation in somatic cells get obliterated as the organism dies. And the Mutation in gamete cells are those mutations which are capable to cause variations in progenies which can led to better survival of the progenies.

guajiro [1.7K]

Answer:

I believe the answer to this question is b observable physical evidence.

Explanation:

The reason for this is because scientists make predictions and use evidence to back up their hypothesis. If the evidence doesn't support their claim, they make up a new one, until they have gathered enough evidence to support their claim. This can be done through past knowledge, like failures and successes and lab experiments, so it is not only each of them, so the answer cannot be c or d. Out of the two options, a and b, I just thought about it and picked b as the reasonable answer. Please give me feedback on the answer, if it is right or not. Thanks! Hope I helped!

Complete the phylogenetic tree by matching each characteristic that arose during the evolution of animals to its correct positio
spayn [35]

Answer:

The correct characteristics are -<em><u> tissue, coelom, segmentation, endoskeleton, and backbone</u></em> from top to bottom boxes.

Explanation:

This phylogenetic tree showing the evolution and relatedness of the different organisms on their shared characteristics. In the given phylogenetic tree there are some characters are missing and we can predict or state them on the basis of evolution and studying the characteristics.

After the Porifera phylum tissue-level organization is found in the organism hence Tissue would be placed in the first box.

The coelom is found organisms above the Nematoda level, which further include a character segmentation in Annelida and Arthropoda. Another lineage from arising with the coelom organism that included endoskelton and backbone.

Thus, The correct characteristics are - tissue, coelom, segmentation, endoskeleton, and backbone from top to bottom boxes.
