Which of the following is an example of an emergent property?

Answers

The emergentproperty is that cell is the basic unit of life, one or more cells combine to form organism. The correct option is A.

What is emergent property?

An emergentproperty is a distinctive feature that an entity acquires after becoming a part of a larger system.

Emergent properties aid in the adaptation of living organisms to their surroundings and enhance their likelihood of survival.

Carrying capacities for all species in an ecosystem's biologicalcommunity are an emergent phenomenon of the ecosystem in its entirety because each species' food supply is a result of what happens in other parts of the ecosystem.

In the given scenario, cells being the basic fundamental structural unit of life, is forming a complete organism. This property of cell is indicating the emergent property.

Thus, the correct option is A.

AP biology questions are very hard. What book should my student be using as a reference?

Answers

Answer:

honestly, it is all up to your preference if you are the tutor or the teacher. It depends on if the student wants to go really in-depth with their work and memorize all the small details, or to know the basics

Explanation:

Final answer:

There are several books that can serve as helpful references for AP biology, including 'Campbell Biology', 'Barron's AP Biology', and 'Cracking the AP Biology Exam'.

Explanation:

When it comes to preparing for AP biology, there are several books that can serve as helpful references. One highly recommended book is 'Campbell Biology' by Jane B. Reece, which is widely used in high school AP biology courses. Another popular book is 'Barron's AP Biology' by Deborah T. Goldberg, which provides comprehensive coverage of the AP biology curriculum. Finally, 'Cracking the AP Biology Exam' by The Princeton Review offers strategies, practice exams, and detailed explanations to help students succeed on the AP biology exam.

In the 1950s, when Watson and Crick were working on their model of DNA, which concepts were well accepted by the scientific community?

Answers

Wilkins and FranklinName: Maurice Wilkins and Rosalind Franklin
Date: 1951
Description: 
- Wilkins was working with a technique called X-ray diffraction: a technique that involved aiming X rays at the DNA molecule
- Franklin took the now famous Photo 51 and collected data eventually used by Watson and Crick
- Photo 51 indicated that DNA was a double helix, or twisted ladder shape, formed by two strands of nucleotides twisted around each other
- The specific structure of the DNA double helix was determined later by Watson and Crick when they used Franklin's data and other mathematical data

Final answer:

In the 1950s, several key concepts related to DNA were well understood in the scientific community, such as the polymer structure of DNA, base pairing rules, and the helical structure of the molecule itself. The established methods like X-ray crystallography also contributed to their research.

Explanation:

In the 1950s, when Francis Crick and James Watson were working on their model of DNA, the scientific community had a well-established understanding of several key concepts. For example, it was well accepted that DNA is a polymer of nucleotides, each containing deoxyribose sugar, phosphate group, and one of four nitrogenous bases, A, T, C, and G; and that purines always pair with pyrimidines.

X-ray crystallography was an accepted method for investigating molecular structure. Chargaff's rules, which state that of the four types of nucleotides present in a DNA molecule, two were always present in equal amounts, were also widely accepted. Finally, it was known that the DNA molecule has a helical structure, thanks to the work of Rosalind Franklin.
