Given the DNA sequence 3'TACCGAGGCATT 5' what is the complementary strand sequence?
Answer:
′UACCAAGGUAG5
Explanation:
DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) residues polymerized by "dehydration" synthesis in linear chains with specific sequences. Each strand has polarity which runs from 5′ to 3′.
In DNA, A pirs with T and G pairs with C.
Fo through the original 5′ to 3′ sequence pairing each A with T ad each C wth G.
While RNA is a single strand molecule. This Strand also consists polynucleotide composed A, C, G and U (uridine).
For a complementary strand replace A with U (because RNA does not consist T), T with A, C with G, and G with C.
Hence,
Given strand: 5′ATGGTTCCATC3′
Complementary RNA strand: 3′UACCAAGGUAG5′
Keep in mind that the complementary strand will read from left to right in the 3 to 5 direction.
Carrie is conducting an experiment on a solution. The solution’s initial pH is 10. Then, as Carrie gradually adds Compound X into the solution, the pH decreases to 5. Which is the most likely identity of Compound X? *
Answer:
Compound X must be an acid
Explanation:
Acids have a lower pH than alkaline solutions. When you add an acid to a solution, the pH drops, as has happened here. If the pH did not change, we would assume compound X was neutral. If the pH increased, we would assume compound X was even more alkaline than pH 10.

Answer:
Today, the basis for how we classify galaxies is still rooted in morphology, or how the galaxies appear. Astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular.
Explanation:
Barred Spiral Galaxy
Barred spiral galaxies share the same features and functions as regular spiral galaxies, but they also have a bar of bright stars that lie along the center of the bulge, and extend into the disk. The bright bulge has very little activity here and contains mostly older, red stars. The bar and arms have lots of activity.including star formation.
While the classification for barred spirals is the same as it is for regular spiral galaxies, the bar must be considered as well. Short bars correlate to tighter galaxies and will be included in the designation SBa. SBb have longer bars and SBc are the longest. Most astronomers now agree that the Milky Way is a barred spiral galaxy.
Elliptical Galaxy
Elliptical galaxies can be recognized by their elongated spherical shape and their lack of nucleus or bulge at the center. Although there is no nucleus, the galaxy is still brighter in the center and becomes less bright toward the outer edges of the galaxy. Stars, gases and other materials are spread throughout the elliptical galaxy. An elliptical galaxy can be nearly round or long and cigar shaped.
It is believed that a great deal of the mass in an elliptical galaxy is due to the presence of a central black hole. These galaxies have very little activity and contain mostly old stars of low mass, because there aren’t the gasses and dust needed to form new stars.
Irregular Galaxy
Irregular galaxies are composed of gasses, dust, stars, nebulous formations, neutron stars, black holes and other elements common to all galaxies. Irregular galaxies are named so because they have no definite shape, but like all galaxies, they are in constant motion, moving outward and away from the center of our universe. Irregular galaxies are divided into two classifications: Im and IO.
Im galaxies occur most often among irregular galaxies and may show a trace of the spiral galaxy arms. IO galaxies are completely random and can be called chaotic in nature. The Magellanic clouds that border our own Milky Way Galaxy are examples of Im galaxies. Approximately 20% of our galaxies are classified as irregular

13. Galapagos finches are birds that live on islands
off the coast of South America. The finches on the
various islands are very different from each other.
As a result of the different food resources on the
islands, which of the following structures of the
Galapagos finches experienced the greatest
change through natural selection?
(5 Points)
Head size
Eye shape
Feather color
Beak shape
Galapagos finches experienced the greatest change through natural selection in the beak shape. The correct option is D.
What is natural selection?Natural selection is the variation in individual survival and procreation brought on by phenotypic variances.
The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.
Short beaks of Darwin's finches proved to be an adaptation that rendered them better adapted to grub-eating and poking holes in the ground.
However, Darwin's theory of natural selection was strengthened by Galapagos finches.
Until they all split off to become separate species, Darwin's Finches' advantageous characteristics were chosen for over many generations. These birds possessed distinct beaks, although being almost identical to mainland finches in all other respects.
Thus, the correct option is D.

1) Briefly describe the process of DNA replication.
a) Start with the molecular machinery and be sure to describe what DNA polymerase does. Use the terms ‘free nucleotides’, ‘helicase’, ‘polymerase’, ‘complementary’.
b) describe the result; how many strands were made? Describe their composition. Use the terms ‘parental DNA’ and ‘new DNA’.
Answer:
The biological process that involves produces two exact copies of DNA from a DNA molecule is called DNA replication.
In this process, the enzyme helicase unzips the DNA double helix by breaking the hydrogen bonds that bind bases together in the structure. Unzipping the hydrogen creates a replication fork. Every strand of the DNA acts as a template but oppositely oriented known as the leading strand in 3’ to 5’ direction and the lagging strand in the 5’ to 3’ direction.
One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the leading strand. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the lagging strand. As a result of their different orientations, the two strands are replicated differently.
Primer acts as an initiating site for DNA synthesis and DNA polymerase enzyme adds new complementary nucleotide base by attached and moving on the leading strand in the direction of 5' to 3' which is reversed to the strand.
After the binding and synthesis of all the bases, the enzyme called exonuclease removes the primer from the strand. One new and an old chain of two DNA molecules are synthesized by DNA replication due to the one new and one parent molecule in DNA it is known as semi-conservative.

isolation occurs when two species occupy different habitats within the same geographical range.
Question:
_____ isolation occurs when two species occupy different habitats within the same geographical range.
Answer:
Habitat
Explanation:
Habitat isolation occurs when individuals in two populations are separated geographically. For example by a river or a mountain range. These organisms are much less likely to interact with each other and attempt to reproduce.
Habitat isolation is a barrier to gene flow (mixing of genes in two populations) and is a mechanism of speciation.

Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
What is mitosis?Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
The chromosomes are separated by a structure called the mitotic spindle. A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones.
These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation. Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
Therefore, Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.

Why are ion channels necessary to transport ions into or out of a cell?
Answer:
Ions carry electric charges and are not soluble in the lipid bilayer of the cell membrane.
Explanation:
I found it on google lol
Ions are too large molecules to diffuse through the cell membrane hence require some proteins to facilitate their transport. Ions channels helps in transporting the ions through the cell membrane and the flow of current through the membrane.
What are ion channels?
Ion channels are the type of transport proteins which are present in the cell membrane that facilitates the movement of ions through the membrane. Cell membrane is selectively permeable in nature and thus does not allow many molecules to transport through it.
Ion channels facilitates the passive movement of ions across the cell membrane and are essential for cell survival. Ion-channels helps in elucidating the structure-function mechanisms of the proteins present in the membrane. Ion channels help in creating ion gradient and moving charge through the membrane.
