The secondary structure of a polypeptide is produced by bonds between amino
acids.
Describe how.
The order in which the amino-acids are placed within the polypeptide determines the tertiary structure and therefore the function of the given protein. Amino acids have different functional groups like methyl(CH3), phenyl(C6H5). Those functional groups can interact with molecules like glucose determining reactions, the proteins that catalyze reactions are called enzymes. Other functional groups of amino acids can be the sulfate groups. For example, insulin has 2 polypeptide chains(Chain A has 21 amino acids, and chain B, 30). Between the two polypeptide chains, 2 disulfide bonds form altering its shape.
The secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.
A hydrogen bond is an intramolecular attraction between a hydrogen atom in one molecule and an electronegative atom (e.g., oxygen) of another molecule.The most common types of secondary structures in proteins are alpha helices and beta sheets.In alpha helices, the carbonyl group of one amino acid is bonded to the amino group of another amino acid spaced four residues apart in the polypeptide chain.In beta-sheets, different regions of the polypeptide line up next to each other, thereby these protein regions interact by hydrogen bonds.In conclusion, the secondary structure of a protein is generated by hydrogen bonds between atoms of the polypeptide backbone.

While studying bacterial cells, scientists measure the lengths of the cells in one colony. The chart shows their data. The scientists notice that one measurement stands out. How should the scientists best deal with this measurement? accept it as true and use 85 micrometers in the data when they find the average length accept it as true but say that it is the only cell that has ever been that long consider that there was an error during measuring and collect further data consider that it is possible but very unlikely for these bacterial cells to be so long
Answer:
C

Describe the stage of the cell cycle that takes place before mitosis.
The _____ stage occurs before mitosis. In this stage extra sub-______ structures are produced.
The interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.
What do you mean by Cell cycle?The Cell cycle may be defined as the process a cell goes through each time it divides.
Interphase is the initial stage of any cell cycle which is the interval between the end of one mitotic or meiotic division and the beginning of another. It is the longest phase of the cell cycle as compared to the mitotic phase.
Therefore, the interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.

How are biodiversity and the cycling of matter
related to maintaining ecosystem services
Answer: biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Biodiversity and the cycling of matter are related to maintaining ecosystem services because they ensure the functioning and stability of ecosystems, which provide important benefits such as air and water purification, pollination, and climate regulation.
What is biodiversity?Biodiversity refers to the variety of life in an ecosystem, including the variety of species, genetic diversity within species, and the diversity of ecosystems and landscapes.
Biodiversity is essential for the functioning and stability of ecosystems and provides important ecosystem services such as pollination, soil formation and fertility, climate regulation, and disease control. Biodiversity also helps to maintain resilience in the face of environmental change and provides food, fiber, fuel, and medicinal resources for humans. The loss of biodiversity due to human activities is a major environmental concern, and conservation efforts aim to protect and preserve biodiversity for the benefit of current and future generations.

Why do cultural universals exist?
Cultural universals exist because all cultures have basic needs and they all develop common features to ensure their needs are met.
What do you mean by cultural universals?A cultural universal is an element, pattern, trait, or institution that is common to all known human cultures worldwide. Taken together, the whole body of cultural universals is known as the human condition.
There are 10 basic elements of every culture: geography, language, family, FCTS (food, clothing, transport, shelter), economics, education, politics, technology, VBR (values, beliefs, rituals), and cultural expression.
Examples of elements that may be considered cultural universals are gender roles, the incest taboo, religious and healing ritual, mythology, marriage, language, art, dance, music, cooking, games, jokes, sports, birth and death.

why do chicken eggs grow larger compared to other eggs?
Answer:
Chicken eggs grow larger compared to other eggs due to their relative body sizes.
Explanation:
Egg laying and the size of an egg is relative to the size of the organism. So an ostrich lays a really large egg because it is a larger animal and can handle that size. Whereas a bluebird lays a small egg because it is a small bird.

Explanation:
Which explanation correctly describes why it is important for a cell's surface-area-to-volume ratio to not be too small? Radio button Not checked 1 of 4
Answer:
Hello. You did not put the options, but we can say that the execution of mitosis is what makes it important that the proportion between the colume and the cell surface area is not small.
Explanation:
The ratio between the surface area of a cell and the volume is very large and this is essential for mitosis to occur and for all cells in the same tissue to have the same content and the same drum.
If a cell increases ten times its surface area, it will increase its volume a thousand times. This shows that the cell volume has a much larger proportion than the surface. This makes the cell have a fast metabolic rate and needs to absorb many nutrients, in addition to making a strong exchange of gases with the external environment. This absorption of nutrients so intense, is essential for the cell to enter mitosis and generate two equal cells. This is because during the growth phase the cell will increase in volume until the growth limit of its surface area, once this limit is reached, the cell will have to undergo mitosis and will have enough nutrients for the entire process.
