Fatty acids are the simplest lipids but they may be a part of or a source of many complex lipids.
What is fatty acid?The building blocks of fat in our bodies and the food we eat are called fatty acids. The body converts lipids into fatty acids during digestion so that they can be taken into the circulation. A molecule known as a triglyceride is created when three fatty acid molecules are linked together.Carboxylic acids joined to alkyl chains are fatty acids. In mammalian systems, the typical fatty acids are unbranched and may contain one or more double bonds. They are cis double bonds. Fatty acids with branched chains and those with aliphatic ring structures are well known.The number of carbon atoms and carbon-carbon double bonds in the chain are used to designate fatty acids.A unique class of fatty acids are called essential fatty acids. They are referred to as such since humans cannot make them on our own and must obtain them from diet. Linoleic acid and alpha-linolenic acid (ALA), which are found in plant oils, are examples of important fatty acids.Learn more about fatty acid here:

The term _____refers to the process of destroying or removing all viable microorganisms including even the hardiest structures, such as endospores.
The term sterilization refers to the process of destroying or removing all viable microorganisms including even the hardiest structures, such as endospores.
Sterilization can be achieved through physical methods such as heat, radiation, filtration, chemical methods which use liquid and gaseous sterilizing agents or by combination of both.
Heat Method is the most common method of sterilization in which heat is used to kill the microbes. Wet Heat or Steam Sterilization is carried out in autoclaves which use steam heated to 121–134 °C under pressure, whereas, dry heat sterilization exposes the specimen containing microbes to high temperatures either by flaming, incineration or a hot air oven.
Filtration deploys use of filters with a pore size that is too minute for the microbes to pass through.
Radiation sterilization involves exposing the contaminated specimen to radiation like UV, X-rays or gamma rays for sterilization.
The commonly used gases in chemical methods of sterilization include a mixture of ethylene oxide and carbon-dioxide.

If 0.43% Fe has molar mass=100 g.
Then, 56 g Fe has molar mass=100×56÷0.43 =13023.26=13Kg mol −1 .
Cytochromes are electron-transporting protein pigments concerned with cell respiration that contain an iron-containing molecule called heme, true to that of hemoglobin. When the iron of heme accepts an electron , it changes from the oxidized ferric (Fe III) state to the, reduced ferrous (Fe II) state. oxidation of cytochromes to molecular oxygen and their subsequent reduction by oxidizable substances in the cell is the main way in which atmospheric oxygen enters into the metabolism of the cell.

Ecologist mark is trying to identify the type of pollution that caused excessive algae growth on a river and killed fishes and plants. which type of pollution caused this situation?
Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae.
Factors influencing Nutrient pollution and their effects:
Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water. Severe algal growth blocks light that is needed for plants, such as seagrasses, to grow. When the algae and seagrass die, they decay. In the process of decay, the oxygen in the water is used up and this leads to low levels of dissolved oxygen in the water. This, in turn, can kill fish, crabs, oysters, and other aquatic animals.Nutrients come from a variety of different sources. They can occur naturally as a result of weathering of rocks and soil in the watershed and they can also come from the ocean due to mixing of water currents. Scientists are most interested in the nutrients that are related to people living in the coastal zone because human-related inputs are much greater than natural inputs. Because there are increasingly more people living in coastal areas, there are more nutrients entering our coastal waters from wastewater treatment facilities, runoff from land in urban areas during rains, and from farming.All of these factors can lead to increased nutrient pollution.To learn more about nutrient pollution: https://brainly.com/question/23857736

During which phase of meiosis do the homologous chromosomes separate and head towards opposite poles of the cell?
During anaphase, homologous chromosomes separate and head towards opposite poles of the cell.
A cell prepares for cell division by replicating its chromosomes, segregating them, and creating two identical nuclei during the mitotic phase. After the metaphase procedure, the mitotic stage known as anaphase occurs during which the freshly replicated chromosomes are transferred to the opposing poles of the cell and the replicated chromosomes are split. Sister chromatids split from one another and are drawn to the opposite ends of the cell during anaphase. The sister chromatids are able to separate because the protein "glue" holding them together is degraded. Each chromosome now exists on its own. Each pair's chromosomes are drawn to the cell's opposite ends.learn more about anaphase here:

It is important to maintain the ph of blood and tissue fluids within normal limits because the structure and function of macromolecules are pH sensitive, and even little variations from normal pH can cause metabolic processes to shut down.
Tissue fluid is found in the spaces around cells. It comes from substances that leak out of blood capillaries (the smallest type of blood vessel). It helps bring oxygen and nutrients to cells and to remove waste products from them.
The two forms of connective tissue in this subcategory are blood and lymph. Both are fluid rather than solid, and neither has the network of extracellular protein fibers that other types of connective tissue have.

Genetic drift is a random process that can produce significant population changes quickly.Allele frequencies in a population are a reflection of genetic variety. Allele frequencies that fluctuate over time may be a sign of genetic drift or a population that has undergone new mutations.The population is evolving if the frequencies of alleles or genotypes differ from the value predicted by the Hardy-Weinberg equation. The allelic frequency is stable from generation to generation in populations that are in the Hardy-Weinberg equilibrium, and the distribution of alleles may be calculated.DISCLAIMER

Meiosis is the process by which cells are produced from a cell that was originally diploid. True or false?.
True; meiosis is the process by which cells are produced from a cell that was originally diploid.
What is meiosis?
The production of offspring by sexual reproduction includes the fusion of two gametes, each with a complete haploid set of chromosomes. Gametes are formed from specialised diploid cells. This specialised kind of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. This kind of division is called meiosis. Meiosis ensures the production of haploid phase in the life cycle of sexually reproducing organisms whereas fertilisation restores the diploid phase. Meiosis occurs during gametogenesis in plants and animals. This leads to the formation of haploid gametes.The key features of meiosis are as follows:
Meiosis involves two sequential cycles of nuclear and cell division called meiosis I and meiosis II but only a single cycle of DNA replication.Meiosis I is initiated after the parental chromosomes have replicated to produce identical sister chromatids at the S phase. Meiosis involves pairing of homologous chromosomes and recombination between them.
