Answer:
The answer is D not sure
Explanation:
Like those of several other insect species, the stages of growth that the nymph cricket undergoes are referred to as "instars." Crickets usually go through eight to 10 instars before reaching adulthood, which takes about two to three months. Crickets start to develop wings at about 1 month of age.
A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. C. a mutation in the genetic code. D. an incomplete separation of chromosomes.
Answer:
C. a mutation in the genetic code.
Explanation:
A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.
From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.

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.

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.

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.

Essential Question: Compare and contrast the structure and function of the major organelles found in plant and animal cells.
Answer: Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

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.
