genetic drift simulation:
When you look at your chart, what did you notice about the fluctuations? What would you expect to see over time? were you ever close to losing an allele?
Answer:
yes
Explanation:
The consequences of genetic drift are numerous. It leads to random changes in allele frequencies. Drift causes fixation of alleles through the loss of alleles or genotypes. Drift can lead to the fixation or loss of entire genotypes in clonal (asexual) organisms

A protein which has many sulfhydryl (-sh) groups may exhibit, _______ a type of bonding providing tertiary structure?
A protein which has many sulfhydryl (-sh) groups may exhibit disulfide bridges tertiary structure.
What are disulfide bonds?A disulfide bond is a covalent bond between two atoms of two (cysteine side chains). Large polypeptide chains (more than 200 amino acids) fold and form domains.
Some proteins have disulfide bridges, which are inter-chain interconnections or between parts of a chain, formed by the oxidation of cysteine radicals. Intracellular proteins generally lack disulfide bonds, while extracellular proteins often do.

The cumulative work of many scientists can often be summarized as theories or laws. how is a theory different from a law
Answer:
A law is something in science that can be proved through experimenting. When the experiment is done properly, the same outcome will be achieved every time. A law does not attempt to explain why something is the way it is, it only states it.
A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.
How does the frequency of a wave relate to the energy of the wave?
Answer:
the higher the frequency and the higher amplitude, the more energy there is.
Explanation:
waves carry energy uh The higher the frequency, the shorter the wavelength. The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases.

What does oxygen poor blood deliver to the
lungs?
A. carbon dioxide
B. glucose
C. water
D. ATP
Answer:
A.carbon dioxide
Explanation:
oxygen poor blood means the blood is rich with Carbon dioxide
The oxygen poor blood delivers to the lungs carbon dioxide out of the body organs and cells. Thus, the correct option is A.
What is oxygen poor blood?The heart is divided into two separate pumping systems, which include the right side and the left side. The right side of the heart receives oxygen-poor blood that is deoxygenated blood from the veins and pumps it to the lungs, where the blood picks up oxygen gas from the alveoli and gets rid of carbon dioxide gas.
Deoxygenated blood has less oxygen or it is oxygen-poor and contains is carbon dioxide rich. The right heart pumps this deoxygenated blood to the lungs where it picks up additional oxygen gas.
As the blood travels through body, oxygen gas is used up, and the blood becomes oxygen poor or carbon dioxide rich. Oxygen-poor blood returns from the body to the heart by the superior vena cava and the inferior vena cava, the two main veins which bring blood back to the heart.
Therefore, the correct option is A.
