Emulsifiers are Multiple Choice molecules with two nonpolar ends that can be used to disperse lipids into polar liquids such as water. molecules with a polar end and a nonpolar end that can be used to disperse lipids into polar liquids such as water. molecules with two polar ends that can be used to disperse lipids into polar liquids such as water. proteins that transport nonpolar substances in the bloodstream. proteins that transport polar substances in the bloodstream.
Answer:
molecules with a polar end and a nonpolar end that can be used to disperse lipids into polar liquids such as water.
Explanation:
The process of emulsification is very important in science. An emulsifier is a substance that is used to disperse hydrophobic substances in a polar substance such as water.
An emulsifier has a hydrophillic head and a hydrophobic tail. The hydrophillic head dissolves in a polar substance such as water while the hydrophobic tail dissolves in the lipid thereby dispersing the lipid in water.
Amylose is a form of starch made up of α glucose monomers that are bound by 1– 4 linkages.
Describe how the molecule would be affected if the subcomponents were joined by 1–6 linkages instead.
Explain how this might affect the function of the resulting molecule.
Answer: Carbohydrates usually function as energy storage or structural materials, and are composed of monosaccharides (simple sugars). All monosaccharides have three carbon atoms with a carbonyl group attached to one of the carbons, and hydroxyl groups attached to the remaining two. Monosaccharides are the primary fuel for metabolic processes, so we need the monosaccharides in carbohydrates to fuel our metabolic processes, making it an important part of our diet. If the subcomponents were joined by 1-6 linkages instead of 1-4 linkages, it wouldn't be called amylose, it would change to glycogen, making it less soluble.
If the subcomponents of amylose were joined by 1-6 linkages instead of 1-4 linkages, the resulting molecule would have a branched structure instead of a linear one.
Amylose is a type of polysaccharide that is found in starch. It is made up of alpha glucose monomers that are joined together by alpha-1,4 glycosidic bonds.
If subcomponents were joined by 1-6 linkage if will result into a branched molecule named as Glycogen.
-The branched structure would make it easier for enzymes to break down the molecule, which could affect how quickly it is digested and how it is used for energy.
Therefore, the change in the linkage would result in a different structure and function of the molecule (glycogen) making it less soluble .

how does a single cell give rise to all the different types of cell, tissue, and organs in human body
Answer:
Over the course of hours, days, or months, the organism turns from a single cell called the zygote (the product of sperm meeting egg) into a huge, organized collection of cells, tissues, and organs. As an embryo develops, its cells divide, grow, and migrate in specific patterns to make a more and more elaborate body.

If a cell has 10 chromosomes when it begins mitosis, how many will it have immediately afterword?
Answer:
Explanation:
Therefore, there will be two daughter cells at the end of mitosis. Each will have 10 chromosomes, if the parent cell has 10. The chromsomes will not have sister chromatids because after mitosis, the duplicated pairs have separated into the two daughter cells. The cells will each be diploid, just as the parent cell was.

A. strands I'd DNA wrapped around proteins.
B. The alleles that cause certain traits.
C. Any organism that cause contains DNA
D. A form of virus that infects cells.
Answer:
A. strands I'd DNA wrapped around proteins.
Explanation:
DNA is securely packed within the nucleus by chromosomes, which are thread-like structures. Histone proteins offer structural support for DNA by coiling it around them. During cell division, chromosomes assist in the replication and distribution of DNA. Each chromosome has a centromere, which separates the p (short) and q (long) arms. The centromere is found at the constriction point of the chromosome, which may or may not be the center.

You will create a molecular clock model for an arthropod gene. Follow these guidelines to make your model:
Your timeline will span from 90 million years ago to the present. The common ancestor in your model is an arthropod that lived 90 million years ago. The gene that you’ll track codes for a protein in the species’ venom.
The DNA sequence you’ll track contains 10 nitrogen bases. You can choose the order of the bases and where the mutations occur.
This gene mutates at a rate of approximately 0.76 base pairs every 17.1 million years. To build your model, calculate the estimated time period it takes for 1 base pair to mutate.
The first time period will only show the common ancestor. At the beginning of the second time period, three lineages will diverge from the common ancestor, each with a different mutation in their gene sequences.
The first and third descendant species will survive for the rest of the timeline. The second descendant species was extinct 50 million years ago.
Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning by constructing a mathematical equation.
Answer:
The mutations occur at a rate of 0.56 base changes every 1 billion years. If this rate stays consistent, the mutation rate can be used to determine when different lineages of a particular species split
Answer:
It takes about 17.1 Million years for a base pair to mutate at a rate of 0.76 base pairs. To get the time it takes for one full mutation to occur, you must divide 17.1 to 0.76 and multiply it by 1. So, (17.1/0.76)×1=22.5. It would take about 22.5 million years for one full base pair mutation to occur. Having this being said, the first descendant with one base pair mutation would change after 22.5 million years from the common ancestor. For the second descendant, it would take 45 million years as 22.5 time 2 is 45. 5 million years later, the second descendant will become extinct while the first descendant survives. The third descendant will take about 22.5×3= 67.5 million years. Now, the first and third descendants will survive while the second descendant is extinct.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?
The correct answer is A. Geological processes.
Explanation
Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.

What type of organisms make up the majority of life on the surface of the pelagic zone?
chemosynthetic bacteria and invertebrates
seaweed and fish
mollusks and seaweed
plankton and algae
The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.
What are the zones of water?
The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.
Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.

Complete a dichotomous key for the 10 leaves on the common leaves sheet
A dichotomous key might be considered a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.
When you have an organism -or part of it-, and you need to identify it taxonomically, you use a dichotomous key. The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.
It is simple to read a dichotomous key. The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism. The key describes specific morphological traits of organisms that are useful for differentiation.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies. You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
Let us analyze simple example using a group of 5 organisms. Let us assume that you do not know their names, and you need to know what is the individual in the red circle (You will find it in the attached files).
Dichotomous key
Statement 1a ----------- The organism is a vertebrate ----------- Frog
Statement 1b------------ The organism is invertebrate ----------- Go to 2
Statement 2a ---------- The organism has a multisegmented
and elongated body, with too many ----- centipede
legs.
Statement 2b ---------- The organism has a relatively short body
and with fewer legs ------------------------------ Go to 3
Statement 3a ----------- The organism has 8 legs ----------------------- Spider
Statement 3b ----------- The organism has 6 legs ----------------------- Ant
As you can see, this a very simple example, but ilustrates how the key provides enough information for you to reah the correct option.

A main strand of a DNA molecule in a protein coding region is transcribed along the following nucleotide sequence: 5' TACATTAAGCCG 3' . Assuming there is no stop codon in this DNA fragment, how many codons does this sequence contain
Answer:
4 codons
Explanation:
In a DNA sequence, codons are in a set of 3 base pairs.
So, we can calculate the number of codons in the sequence by dividing the total number of base pairs by 3.
There are 12 base pairs in the sequence. Divide this by 3:
12/3
= 4
So, there are 4 codons in this sequence.
difference between diabetes mellitus and diuresis?? please help
Explanation:
If you have been in EMS long enough, you may well have encountered a patient with diabetes insipidus. Like many, you may have assumed that it is a variant of the common disease diabetes mellitus. Actually, diabetes mellitus and diabetes insipidus are totally unrelated other than the name. The term diabetes is derived from Latin (originally Greek) and means “to go through or siphon,” referring to a large amount of urine produced by the kidneys. The term melitus, in Latin, means “sweet.”
