In 1998, paleoanthropologist Rick Potts published an article in The Yearbook of Physical Anthropology, a peer-reviewed journal. The article was titled “Environmental Hypotheses of Hominin Evolution.” In his paper, Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species. Which would most likely be found in his paper? a review of modern human anatomical structure
evidence of changing environmental conditions, with references
the reasons competing hypotheses are wrong
his opinion of what will happen to the survival of the human race

Answers

Answer 1

Answer: All of the options could reasonably be a part of the paper, and all of them would make the paper better. But one of the options is actually absolutely necessary: evidence of changing environmental conditions, with references- this is the correct answer.

This is because his argumentation is based on the assumption of "great variations in environmental conditions over time "- so he has to proove that there were those variations.

Answer 2

Answer:

The most appropriate answer would be "evidence of changing environmental conditions, with references".

As Mr. Potts claimed that great variations in environmental conditions over time were responsible for the adaptability of humans and the success of our species in his paper, he must have mentioned evidence of changing environmental conditions with references.

In addition, he must have shown the effects of changing environmental conditions on the adaptations made by human species due to those changes.

In a certain mutant strain of bacteria, the enzyme leucyl-tRNA synthetase mistakenly attaches isoleucine to leucyl-tRNA 10% of the time instead of attaching leucine. These bacteria will synthesize:

Answers

Answer:

The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

Explanation:

The missing options of this question are:

A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.

B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.

C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.

D. no proteins, because the inappropriately activated tRNAs will block translation

The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".

In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.

Explanation:

Rhizoids are the _____ of bryophytes.

Answers

The answer is root hairs.

Rhizoids derive from epidermal cells of bryophytes. They are hair-like structures similar to roots of vascular plants. But, they are unicellular structures, unlike roots, which are multicellular. Not only they look alike, but they have similar functions as roots. The functions of rhizoids are the absorption of water and minerals from the soil and a support of the bryophytes.

Scientists notice structural similarities between fossils of a land animal and an aquatic organism. They know the similarities are not a result of the two organisms having to adapt to similar environments. What can they attribute the structural similarities to?convergent evolution
common ancestry
transitional evolution
similar mating habits

Answers

The correct answer is common ancestry. Common ancestry is the explanation for species from completely different environments having similar features. For example: there is fossil evidence that whales are actually evolved from wolf-like animals due to fossil evidence of a transitional evolutionary stage (this is the fossil that can help provide evidence of this common ancestry) that shows a common ancestor between land mammals and whales.

When homologous structures are found in different groups, an ancestry relationship can be stablished between them. Otion B. Scientists can attribute the structural similarities to common ancestry.

Ancestry between groups

Fossils provide good information about the existing relationship between different groups,

ancient and modern

aquatic and terrestrial

The existing homologousstructures between these organisms might be relatively similar, suggesting a common origin.

These structures can show changes in the number of pieces composing them, their arrangement pattern, or their sizes and development degree. These differences reflect the changes that the groups suffered through evolution.

The pattern in which the composing pieces are arranged is useful to study the lineage evolution.

By looking at the structures' composition and arrangement, scientists can interpret how evolutive processes occurred.

Scientists can attribute the structural similarities to common ancestry.
