Explanation:
what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

Enzymes are (a)__________ which speed up the biochemical (b)____________ in living organisms. The enzymes themselves are not changed in these reactions, that is they are biological (c)________. Enzymes are (d)_________- each one controls only one type of reaction. They are (e)_________by high temperatures and by extremes of ph.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
Explanation:
Maybe this will help?
Enzymes are proteins that speed up the biochemical reactions in living organisms, and they are biological catalysts. Enzymes are substance-specific, each one controls only one type of reaction. They are denatured by high temperatures and by extremes of ph.
What are enzymes?Enzymes are biocatalysts made up of proteins, that increase the speed of the reaction.
Enzymes do not involve in the reaction and in the end of the reaction they separate from the reaction their substance is specific they are specific to reactions whose speed is increased by these enzymes.
In high temperatures and pH their structure changes as they are protein and with extreme where they also get the nature

10. Explain how both a population of moose and wolves in the same area could each affect the
size and distribution of the plant population in a community:
Answer:
Since moose are herbivores, they could cause a plant population to decrease in size.
Since wolves are carnivores and hunt moose, there would be less moose feasting on plants, so the plant population would be allowed time to grow back larger.
Depending on how many wolves there are to moose, the plant population will tend to vary.
For example: If the moose population is greater than the wolf population, there will be a smaller population of plants. On the other hand, if the wolf population is greater than the moose population, there will be a greater population of plants.
Hope this makes sense :)

what is the species that is most distinct through the largest number of genetic differences or the most different morphologically, compared to other species of interest, called?
An outgroup is a distantly related group of animals used to determine the evolutionary relationships of the ingroup.
What are outgroup species?An outgroup, which differs from sociological outgroups, is a group of organisms that are more distantly connected and that is used as a reference group when assessing the evolutionary relationships of the ingroup, the group of organisms that are the subject of the study.
Looking at a closely related species that is known to be phylogenetically distinct from the group of species we are researching is known as the "outgroup comparison" strategy. It is likely that the character state in that outgroup was ancestral to the group under study.

Amino acids form peptide bonds through dehydration. Explain the role of water in this process by describing the chemical reaction.
Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Explanation:
Peptide bonds are- Any reaction that combines two monomers in a reaction that generates H2O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.

how many almonds does it take to make a gallon of almond milk
Depending on the recipe and consumer preference, one gallon of almond milk may require more or less almonds.
As a general estimate, one cup of almonds (about 140–160 grams) will yield one gallon (3.8 liters) of almond milk. Remember that this is only a rough estimate and the exact amount of almonds used may vary depending on the desired thickness and intensity of flavor.
Additionally, recipes for some commercial almond milk brands may call for different ratios or other ingredients. If you are producing almond milk at home, you can modify the quantity of almonds as per the flavor and consistency you choose.

nadph and atp are two molecules produced during the light-capturing reactions of photosynthesis. what are these molecules used for later in photosynthesis in the calvin cycle?
Given the characteristics of the Calvin cycle, we can conclude that NADPH and ATP will be used to reduce carbon dioxide to sugar.
The Calvin cycle is known as a light-independent reaction, meaning it can occur during the dark phase of photosynthesis. It is often called the carbon reduction cycle, given that it does just that. In this cycle, carbon is reduced into a sugar known as G3P. In order to do this, it requires NADPH and ATP.
As with most reactions at a cellular level, it requires ATP. This molecule is that of Adenosine triphosphate and is often known as the "molecular currency" given how common it is as a requirement for reactions to take place. ATP is the source of energy for the Calvin cycle.
Meanwhile, NADPH is also required for the Calvin cycle. The main function of the Calvin cycle is to reduce carbon dioxide through a series of steps in order to produce G3P. In order to reduce CO2, hydrogen atoms are necessary. NADPH acts as a carrier of these hydrogen atoms, offering the ions needed for the reduction to take place.
