Answer:
C the humming bird will not live as long as the others
Explanation:
It won't be able to gain sufficient resources/ necter like the others hence it will most likely have poor body condition and will not live as long.
One hummingbird is born with a short, stout beak as a result of a genetic mutation, the humming bird will not live as long as the others.
What is mutation ?Mutations are defined as the change in the nucleotide sequence of genetic material due to different process such as substitution, deletion or insertion of the nucleotides leading to changed or faulty protein.
The type of mutations leads to the early and delayed termination of the transcription of a gene, mutation of a single nucleotide leads to termination of transcription otherwise called as nonsense mutation.
If a mutation shows no effect on the protein, known as the silent mutation.
It won't be able to gain sufficient resources/ necter like the others hence it will most likely have poor body condition and will not live as long.

Based on this data, what can be concluded about the impact
seasonal changes have on these organisms around the Barents Sea?
A. The availability of solar energy limits photosynthetic productivity in winter months
B. Seasonal Changes have no impact on these organisms
C. During winter months the Diatom and zooplankton population completely die off due
to the lack of sunlight.
D. Due to the availability of solar energy, Diatom mass peaks in July.
Answer:
D. Due to the availability of solar energy, Diatom mass peaks in July.
Explanation:
Diatom are the photosynthetic algae which prepare food for themselves from the solar radiation just like plants. These diatoms produce more biomass or vegetation in the summer season mainly in July because availability of more sunlight in the Barents sea region while on the other hand, less biomass in the winter season due to low temperature and solar radiation which also effects the population of zooplankton organisms. So we can conclude that seasonal changes have a great impact on the organisms living around the Barents Sea.

The gravitational force between two objects will be very small, unless...
Group of answer choices
the objects are very far apart
the objects have very large masses
the objects are in the solid state of matter
the objects are spinning
Answer:
the objects have very large masses or an object in circular orbit. This has motion but its always being to pulled to earth by gravity.
Greater gravitational forces will be used to attract heavier things, since the gravitational force is directly proportional to the mass of both interacting objects. Two objects are attracted to one another by gravity as their respective masses increase. Thus, option B is correct.
What is the role of large masses in gravitation force?The gravitational pull between two objects changes inversely with their squared distance and directly with their large masses.
As a result, the gravitational force between the two items would decrease to one-fourth of its initial strength when the large masses of both objects are halved without affecting their distance.
Therefore, The objects are either in a circular orbit or have extremely large masses. Although something is moving, gravity is always bringing it dangerously close to the ground.

Explanation:
I answered a similar question like this yesterday,
Hope it helps!!
The organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as turtles, which is Testudines, which is present in Option A.
What is DNA sharing among ancestors?Organisms that are closely related evolutionarily tend to have more similar DNA sequences than those that are more distantly related because they share a more recent common ancestor and have had less time to accumulate genetic differences. Turtles belong to the class Reptilia, which includes other reptiles like lizards, snakes, crocodiles, and birds. Within the reptile class, turtles are classified under the order Testudines, and other members of this order include tortoises and terrapins that share common characteristics with turtles.
Hence, the organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as the turtles present in Option A.

Explanation:
The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.
A new protein factor named PF2 was recently isolated from mammalian cell nuclei. Among other protein domains, PF2 exhibits an RPD3-interacting domain (RPD3 contains the catalytic activity of the HDAC B complex) and a TFS-interacting domain (TFS is a DNA binding protein). PF2 does not have a DNA binding domain, however. Predict a likely function of PF2 and justify it. The importance of both domains should be explained.
Answer:
The likely functions of PF2 includes binding of several protein factors and DNA structure formation
Explanation:
PF2 contains RPD3 and TFS domains
The likely functions of PF2 includes binding and DNA structure formation
For the RPD3 domain that contains the catalytic activity of the HDAC B complex its function is to interact with other protein factors by binding with them and carrying out the process of the signaling cascade.
while the TFS - interacting domain have likely functions like ; DNA replication, DNA repair and storage. It also has the function involving the DNA structure

Answer:
This ice layer insulates the water below it, allowing it to stay liquid, which allows the life within it to survive. If ice sank, the liquid water on top would also freeze and sink, until all the liquid water became frozen. Water is less dense as a solid, than as a liquid, which is why ice floats.

What is Cell theory?Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.
Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.

You isolate an organism from a water sample and test it with a catalase test and grow it in thioglycollate medium. The results showed bubbling after the addition of hydrogen peroxide and a band of growth at the top of the thioglycollate tube. What is the most likely oxygen classification of your organism
Answer: The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM.
Explanation: Most medically important bacteria can be grown artificially in the laboratory provided the atmospheric conditions and temperature are correct and the culture medium used contains the required nutrients.
The thioglycollate medium is used to differentiate oxygen requirements in an isolated organisms. While catalase test is used to differentiate catalase producing from non-catalase producing organisms.
Differences in the effect of oxygen on bacterial growth provide a further way of classifying bacteria:
● OBLIGATE AEROBES, which require free oxygen to grow,
● obligate anaerobes, which are unable to grow in free oxygen,
● facultative anaerobes, which can grow in conditions in which oxygen is present or absent,
● microaerophiles which grow best in conditions of reduced oxygen concentration.
The most likely oxygen classification is OBLIGATE AEROBIC ORGANISM because from the result of the test carried out on the isolated organisms,
--> The organism is catalase positive as it was able to breakdown hydrogen peroxide to oxygen and water( bubbling after the addition of hydrogen peroxide confirmed it as positive). Catalase is an enzyme produced by all aerobic organisms.
--> while in the thioglycollate medium the organism grew at the top of the test tube in order to absorb maximal amount of oxygen.

Answer:
The mRNA strand for TATACGA is UTUTGCT.
Explanation:
The DNA bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Each of these bases pairs with a complimentary one. Adenine pairs with thymine, and cytosine pairs with guanine.
During transcription, the DNA is transcribed into an mRNA strand. The mRNA has the same complementary bases of the DNA strand, with the difference that instead of having adenine base the complementary base of thymine, it has uracil (U). When we interpret the DNA strand TATACGA, the mRNA will be adenine (A) paired with the DNA's thymine (T), uracil (U) paired with the DNA's adenine (A). Then the same sequence repeats itself. After that, guanine (G) pairs with DNA's cytosine (C), cytosine (C)pairs with the DNA's guanine (G), and lastly, thymine (T) with the DNA's adenine (A).
Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position. If branch migration causes heteroduplex formation across this position, what is the expected outcome
Answer:
Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d
Explanation:
The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.
