In DNA, different alleles of a gene have a different sequence of nucleotides. Alleles may have a different sequence of nucleotides in RNA that result in a different sequence of amino acids in a protein. Therefore, proteins produced from different alleles of a gene may have different structures and functions and result in different characteristics.
What are nucleotide?Nucleotides are the building blocks of DNA and RNA. They are composed of a sugar, a phosphate group, and a nitrogenous base. There are four types of nitrogenous bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the base thymine is replaced by uracil (U). The sequence of nucleotides in DNA or RNA determines the sequence of amino acids in a protein. Proteins are made up of long chains of amino acids, and the sequence of these amino acids determines the protein's three-dimensional structure and function.
Alleles are different versions of a gene. They can result from mutations or changes in the DNA sequence. Different alleles of a gene can produce proteins with different structures and functions, which can result in different characteristics in an organism. For example, the gene that determines eye color has several different alleles, which can result in different eye colors in people.

Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.
What are bacteriophage?Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.
Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.
A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.
The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.
Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.
Therefore, the correct option is D.

Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. Because CO2 produces an acid in water, BTB can indirectly measure how much CO2 is present in a solution. When placed in solutions with neutral pH (little CO2), the solution appears green. In solutions with low pH (high CO2), the solution appears yellow.
A teacher performed a demonstration to investigate how photosynthesis and respiration cycle carbon and oxygen. She placed a few drops of BTB in a test tube containing distilled water. Because distilled water has a neutral pH, the solution appeared green. The teacher used a straw to blow into the solution, and the solution turned yellow. She then placed an aquatic plant into the test tube, covered it to keep it air tight, and placed it under a light for 24 hours.
What color would the solution in the test tube be after being in the light, and what would it be if it were then placed in the dark for 24 hours, and why?
A
Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.
B
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; green after being placed in the dark because the plant could not photosynthesize in the dark.
C
Green after being placed in the light because the plant would remove CO2 by photosynthesis; green after being placed in the dark because no CO2 would enter the tube since it is air tight.
D
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; yellow after being placed in the dark because no CO2 could leave the tube since it is air tight.
Answer:
A. Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.
Explanation:
According to this question, Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. The presence or absence of CO2 in a solution decreases or increases the pH of the solution respectively.
- BTB appears green in a neutral pH i.e. little CO2
- BTB turns yellow in a low pH i.e. high CO2
Plants, in the presence of light, will perform photosynthesis and use CO3 as a reactant while in the dark, will perform cellular respiration and release CO2 as a waste product. Hence, in this case where an aquatic plant was placed into a test tube and covered it to keep it air tight.
- When placed under light for 24 hours, the aquatic plant will undergo photosynthesis and remove CO2 from the solution to make the solution appear GREEN due to neutral pH.
- When placed in the dark for 24 hours, the aquatic plant will undergo cellular respiration and release CO2 into the solution making the solution appear YELLOW due to low pH.

what is the difference between cell structure and cell function?
Answer:
These cells have a membrane-bound nucleus that houses their DNA and contain extensive internal organelles (“little organs”) that perform specific functions. ... Differences occur in size, shape, and presence and number of various organelles and other structures. Each cell's structure correlates with its specific function.
Explanation:
Answer:
A cell can be defined as the smallest unit of life and an example include muscle cells. An aggregation of cells form tissues.
The major difference between a cell structure and cell function is in their functions and physical properties.
Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.

Sex Linked Inheritance
Why are women often carriers of X-linked traits but rarely affected by them?
Answer:
See the answer below
Explanation:
Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.
Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.
The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.
This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.
Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.
Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.
In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.
In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.
The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.
Therefore, women are often carriers but are rarely affected by them.

What is the probability of short beaks in the offspring of the cross show above
Answer:
8/16 or 1/2
Explanation:
This question is a dihybrid cross involving two genes, one coding for feather color and the other for beak length. The alleles for green feathers (G) and long beak (L) are dominant over the alleles for yellow feathers (g) and short beak (l).
According to this question, a male with genotype GGLl was crossed with a female with genotype Ggll. The following combination of gametes is produced by each parent:
GGLl - GL, Gl, GL, and Gl
Ggll - Gl, Gl, gl and gl
Using these gametes in a punnet square (see attached image), the following offsprings in the following proportions will be produced.
Green feathers, long beak (GGLl, GgLl) = 8/16 or 1/2
Green feathers, short beak (GGll, Ggll) = 8/16 or 1/2
Hence, the probability of short beaks (ll) in the offspring of the cross is 1/2.
