Describe the intermolecular interaction of the surface carboxylate groups of a micelle and the surrounding water.
Answer:
Hydrophilic portions are outside and hydrophobic regions are inside
Explanation:
A micelle is an assembly of amphiphilic molecules formed in a liquid solution, generally an aqueous solution. Micelles are formed due to the packing (aggregation-like) behavior in which single-tail lipids are organized in a bilayer. A typical micelle in aqueous solution forms a spheric assembly where carboxylate ions are organized in a mode that hydrophilic head regions enter in contact with the surrounding water, while hydrophobic (lipophilic) portions are disposed inside the micelle.

We can find four principal layers composing the digestive tube walls. From the lumen to the exterior: Mucosa, Submucosa, Muscle, and Serosa Layers.
-----------------------------
There are four principal layers composing the digestive tube walls.
From the lumen to the exterior of the tube, we can find,
Mucosa Layer
Composed of lining epithelium, a propria lamina of connective tissue, and a smooth muscle layer.
The epithelium works as a barrier that separates the lumen from the organ.
Propria lamina has glands, vessels that get the absorbed substances, and immune system elements.
The smooth muscle delimitates the mucose from the submucosa layer. It produces movements that are independent of the rest of the organ's movements.
Submucosa Layer
Dense connective tissue is placed under the mucosa.
It has bigger vessels that ramification to the mucose, muscle layer, and serosa layer.
In certain areas, this layer also has glands.
Muscle Layer
Composed of two or three concentric smooth muscle layers that differ in their orientation.
The contraction of these layers mixes and propels the content of the lumen of the digestive tube.
Serosa layer
Connective tissue membrane covered by simple plane epithelium.
High caliber vessels are placed in this layer and limphatic vessels.
There are regions of the digestive tube where there is no serosa layer. Instead, there is a connective tissue named the adventitious layer.

Describe how scent and taste work in conjunction. Are the tastes of below mention foods that were tested heightened by the sense of smell, or only some of the foods?
a. Salt
b. Sugar
c. Lemon Juice
d. Coffe grounds
Answer:
Scent and Taste work in conjunction because when your brain smells food, it pulls up a picture or memory of that food in your head, and you remember what it tasted like and if you enjoyed it.
Only some of the food. Salt does not really have a smell, so it does not do anything, but all the others do and are heightened
Explanation:
Take cotton candy for example. When you smell cotton candy, you smell SUGAR and lots of it. You know that sugar tastes good and as such you now want to eat the cotton candy.
For this example, we will use lemonade. Lemonade is commonly a drink that most love on a hot summer day at the beach. When you smell the lemonade, it reminds your brain of how good it tasted and pulls up the memory at the back of your mind, making you feel happy and relaxed. It then ends up tasting better
(This is my first answer, it won't be perfect)
Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.
What is Conjuction?Since salt doesn't truly have a fragrance, it has no effect; nevertheless, all the others do and their intensity is increased.
You can definitely smell a lot of sugar when you smell cotton candy. You want to eat the cotton candy because you are aware that sugar tastes delicious.
On a hot summer day at the beach, most people enjoy drinking lemonade.
Therefore, Smell and taste go hand in hand because when you smell food, your brain conjures up an image or recollection of that food in your head, allowing you to recall how it tasted and if you liked it.

Which of the following is responsible for the conversion of covalently closed circular DNA to supercoiled DNA of the plasmid of: a) endonuclease b) DNA gynase c) topa isomerase d) exonuclease
Answer:
DNA gyrase
Explanation:
DNA gyrase is a bacterial enzyme that plays an important role in catalyzing the negative supercoiling of circular chromosomal DNA. This enzyme belongs to a class of enzymes called topoisomerases which play a major role in transitioning of DNA structure. DNA gyrase conversion of covalently closed circular DNA to supercoiled DNA is ATP-dependent.
The importance of DNA gyrase cannot be overemphasized, because for DNA synthesis to occur, the DNA must have a single-stranded template, hence, DNA gyrase play an important role in unwinding the double-stranded DNA for replication. It has the ability to introduce negative supercoils and relax positive supercoils prior to replication.

The removal of sections of RNA, called introns, occur at which regulation step in eukaryotic cells? (1 point)
o mRNA life span
O post-translation
O RNA processing
ochromatin remodeling
Answer:
post-translation
Explanation:
When a eukaryotic gene is transcribed in the nucleus, the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. Instead, it's an "immature" molecule called a pre-mRNA.
The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.
Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons. This process is called splicing.
In the process of alternative splicing, different portions of an mRNA can be selected for use as exons. This allows either of two (or more) mRNA molecules to be made from one pre-mRNA.
Answer:
RNA processing
Explanation:
RNA processing. Splicing, capping, and addition of a poly-A tail to an RNA molecule can be regulated, and so can exit from the nucleus. Different mRNAs may be made from the same pre-mRNA by alternative splicing.

Recent research has found that on one island of the Galapagos two finch species interbred. This interbreeding may have resulted in a hybrid species that ultimately led to the extinction of one of the species Darwin discovered. They call this speciation in reverse, or despeciation. Based on what you know about speciation, why are these terms appropriate?
Answer:
Speciation is defined as an evolutionary process in which one population evolves into a distinct species.
Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.
In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.
Answer:
Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.
Answer:
D
Explanation:
The correct option would be therapeutic cloning.
First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.
Artificial clonings are of different types, namely:
Reproductive cloningGene cloningTherapeutic cloningReproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.

If one half of a DNA molecule has 8 thymine bases, what else is also true about the DNA molecule? ( point)
There will be 16 total bases.
There will be 32 total bases.
There will be 8 adenine bases.
There will be 8 cytosine bases.
Answer:
There will be 8 adenine bases.
Explanation:
There are total of 4 nitrogenous bases present in a DNA that includes Adenine, Guanine, Thymine, and Cytosine. These nitrogenous bases form complementary base pair in which, adenine form two hydrogen bonds with thymine and cytosine form three hydrogen bond with guanine.
So, if there are 8 thymine bases in a DNA (irrespective of half or full) then there will be 8 adenine bases, forming two hydrogen bond with each other.
Hence, the correct answer is "There will be 8 adenine bases."
