__________ amino acids are those amino acids that do not need to be obtained from the diet because the body is capable of synthesizing (producing) them.
Substances or mixtures of substances known as buffers, act in living things to resist changes in ______. multiple choice question.
Answer:
pH
Explanation:
Substances can act as a buffer to resist changes in pH when something more acidic or basic is added
Substances or mixtures of substances known as buffers, act in living things to resist changes in pH.
What are the uses of pH?pH is an important quantity that reflects the chemical conditions of a solution. The pH can control the availability of nutrients, biological functions, microbial activity, and the behavior of chemicals.
If the pH of their body or their environment fluctuates too much the organism can die. This is particularly true for human beings. For example, blood is normally slightly basic, with a pH range of 7.35 to 7.45.
Different organs function at their optimal level of pH. For example, the enzyme pepsin requires low pH to act and break down food, while the enzymes in intestine require high pH or alkaline environment to function.

Must every member of a particular species be able to reproduce in order for the species to survive.
It is not necessary for every members of a particular species to must reproduce in order for the species to survive.
For a given species to survive, not every individual needs to be able to reproduce. because as long as some of the individuals are reproducing the species number will be maintained enough so that it could survive.
Take homo sapiens (Humans) as an example. Many males and females worldwide are sterile and unable to procreate, yet the human species is still thriving.
Also, if we take ants and bees as an example it has a particular cast called reproductive caste which is able to reproduce and all other individuals have their certain assigned duties and still the queen only produce such huge amounts of eggs that they are still surviving.

how will different additives affect hydrogen bonds between different water molecules (soap, sugar, oil)? CER question
Soap is a surfactant, or a compound that lowers the surface tension of a liquid. Soap, in particular, decreases the surface tension of water by weakening the hydrogen bonds that make water such a special substance.
The three sugars interacted with water molecules in different ways. Mannose, the least sweet of the sugars, formed longer and weaker hydrogen bonds with water than glucose or fructose. Fructose, the sweetest of the sugars, formed the shortest and strongest hydrogen bonds with water.
Oil molecules, however, are non-polar, and they can't form hydrogen bonds. If you put oil and water in a container, the water molecules will bunch up together and the oil molecules will bunch up together, forming two distinct layers.
What is the bond called between the two different types of atoms of water?Opposites attract, so this lopsided charge difference allows bonds to form between the hydrogen and oxygen atoms of adjacent H2O molecules. Each H2O can bind to a maximum of four neighbors through these so-called hydrogen bonds.

Which nitrogenous waste removed by the kidney is produced by the breakdown of nucleic acids?
Answer:
Nitrogenous waste removed by the kidney is produced by the breakdown of nucleic acids is uric acid.
Explanation:
Purine nucleotides are broken down metabolically into uric acid, which is a typical part of urine. Increased levels of uric acid into the blood may cause arthritis and are linked to other illnesses including those of diabetes and the development of kidney stones made of ammonium acid urate. Nitrogenous wastes like Urea as well as uric acid are indeed the primary nitrogenous waste products. Whereas uric acid is produced by the breakdown of nucleotides, urea is produced by the breakdown of amino acids. The metabolism of amino acids produces urea, which is the body's primary nitrogen-containing- containing waste product. Purine metabolism generates uric acid as a byproduct. Because of the absence of uricase, a crucial enzyme that transforms uric acid into water-soluble compound active ingredients, high levels of blood uric acid have the potential to remain in humans as well as relatively high primates.

The scientist whose work provided the foundation for later understandings of genetics was Gregor Mendel.
Gregor Mendel is known to be the father of genetics because of the study he made of seven traits of a pea plant in order to study the passing on of traits. The two laws formulated by Gregor Mendel referred to as the 'law of segregation and 'the law of independent assortment' served to lay the foundation of modern genetics.
Gregor Mendel was able to predict the transmission of alleles or genes from parents to offspring even before the genes were discovered. The concept of dominant and recessive traits was also brought up by Gregor Mendel. Hence, due to such revolutionary findings, Gregor Mendel is known to be the scientist who laid the foundations of genetics.

List and describe different ways a population can become reproductively isolated from other populations of the same species. (3)
When populations grow to be re-productively isolated, they are able to evolve into separate species. Reproductive isolation can expand in a number of ways, which include behavioral isolation, geographic isolation, and temporal isolation. Specification is the formation of a brand new species.
Factors including geography, conduct, and time can separate populations and cause reproductive isolation. In geographic isolation, the populace is separated via way of means of a bodily barrier, including mountains, rivers, and oceans. In conduct isolation, behavioral styles set variations among species in phrases in their interbreeding strategies including courtship rituals and reproductive strategies. On the opposite hand, time acts as an setting apart mechanism if species reproduce offspring at exceptional times.
