What are cell organelles?An organelle is a type of subcellular structure that, much like an organ in the body, is responsible for performing one or more specialized tasks within the context of the cell. The nucleus, which are responsible for storing genetic information, the mitochondria, which are responsible for producing chemical energy, and the ribosomes, which are responsible for assembling proteins, are some of the more essential organelles found in cells.
The nucleolus, the nucleus, the ribosome, the vesicle, the rough endoplasmic reticulum, the Golgi apparatus, the cytoskeleton, the smooth endoplasmic reticulum, the mitochondria, the vacuole, the cytosol, the lysosome, and the centriole are the major organelles and structures found within the cytoplasm.

A virus inserts its DNA into the DNA of another organism. C. High-energy waves like UV light or radiation physically damage the DNA. D. A repair DNA polymerase fixes a damaged DNA strand.
Answers
Answer: Option C.
High-energy waves like UV light or radiation physically damage the DNA
Explanation:
Mutation is the change or alteration that occur in the DNA sequence or nucleotides sequence of an organism which is caused by mistakes when the organism is copied or environmental factors such as UV light.
Ultraviolet light cause mutations by activating the SOS repair systemof which is a part of i a new DNA polymerase that has no power to edit e but has the ability to move past the thymine dimer and synthesize DNA, This lead to cells able to replicate but with a high frequency of mutations.

A person in a dark room looking through a window can clearly see a person outside in the day light . But a person outside cannot see the person inside
Answers
Explanation:
The explanation for this is that the space outside is illuminated with light from the sun. The person inside has either a lesser or no illumination at all. The dark inside room appears dark, and darkens the surface of the window facing inside, making it act like the silvered surface of a mirror. When the outside observer looks at the window, the window acts as a mirror, reflecting the light from the sun onto the eyes of the outside observer. For the inside observer, some of the illumination from outside finds its way inside, since the outside window surface is well lit, carrying with it the sensation of vision onto the eyes of the inside observer.

Answers
Answer:
Explanation:
Human activities had led to diversity of species in ecosystem. Some of the species of animal have been lost and displace due to human activity such as deforestation, construction, company establishment.
Clearing of land for agriculture use has also contributed to diversity that occur in the habitat of an animal.
Diversity of an habitat leads to an unstable ecosystem, as animals can no longer thrive and live in their environment, some species of animals are lost including important species in the environment in the process and others struggles to survive.
Reduction of human activities in animals natural habitat can help restore diversity.
Do you know the Transcription factor name for lapF and naphthalene dioxygenase?
Answers
Answer:
The LapF gene encodes one of the largest proteins from Pseudomonas putida, it is required for the bacterial colonization on the solid surfaces; while naphthalene dioxygenase is an enzyme required for the process of aerobic degradation of naphthalene.
Explanation:
LapF is a gene of Pseudomonas putida that is critical during the process of plant root colonization. Mutations in this gene have shown to reduce the ability to colonize plant tissues. On the other hand, the naphthalene dioxygenase gene is also encoded by the genome of Pseudomonas strains. The naphthalene dioxygenase protein catalyzes the hydroxylation of different substrates, however, this enzyme is widely known for acting during the degradation of naphthalene, an organic chemical compound that is toxic in humans.
Smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf. Three offspring resulted: one big-footed and blue and two small-footed and blue.Which statement about the inheritance of color in smurfs is most likely to be correct?
Answers
Answer:
See the answer below
Explanation:
The most correct statement would be that the blue color is dominant over the white color.
According to Mendelian law, when there are two different versions of the same gene/trait in which one is dominant and the other is recessive, the dominant version will be expressed while the recessive version only stays in the background.
In this case, the alternate versions of the same trait in the smurf are the white and blue colors. When they are mixed together in the offspring, the blue color is expressed and the white color stays in the background. It means the blue color is dominant over the white color.

Which of the following statements associated with cellulose is false? A) It's a linear polymer of glucose. B) The glycosidic linkage is β(1 → 4). C) Hydrolysis is accomplished enzymatically by cellulase. D) Most animals can easily digest this compound.
Answers
Answer:
Most animals can easily digest this compound
Explanation:
Cellulose is a linear polymer of glucose comprising of beta 1,4-glycosidic linkage of glucose molecules; this is where it differs from starch. Cellulose is a polysaccharide made of glucose monomers just like starch. The enzymatic hydrolysis of cellulose is achieved by the enzyme cellulase.
Not all animals can digest cellulose. As a mater of fact, no vertebrate can digest cellulose directly. Many herbivorous animals possess symbiotic bacteria in their gastrointestinal tract which enables the digestion of cellulose. These bacteria possess the requisite enzymes for the digestion of cellulose.

2. How might a mutation that causes a single letter change in the DNA sequence affect
your protein structure and function?
Answers
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.
ex. sickle cell disease - a single letter swap in the gene that encodes the hemoglobin molecule results in deformed red blood cells

After getting the slide and microscope ready, Stella is eager to see the microscopic pond water specimen! She crouches around her microscope and aligns her eye with the microscope’s eyepiece. But she's only able to see a bright white light. At this point, no specimens or cells are visible on Stella's pond water slide. After taking a moment to collect her thoughts, Stella realizes she can't see any lifeforms because a.the microscope is not yet in focus b.the microscope is not plugged in c.there are no specimens on the slide d.she hasn't fastened the slide to the stage
Answers
Answer:
she hasn't fastened the slide to the stage
Explanation:
In Microscopy even if the slide is not yet in focus,she will be able to see part of the slide which may appear as transparent image.Therefore this is a wrong answer.
If the microscope is not plugged it light can not come up.
If there are no specimen on the slide,the slide will still as transparent image at the focus.
No doubt Stella forgot to fasten the slide to the stage.,therefore the specimen on the slide was not in focus of the objective lens,rather she was focusing on the stage only,hence the visible white light.
Students make these mistakes in microscopy,they sometimes place the slide on the stage,but forget to fasten the stage clip,thus the slide is not in focus of the incident light,which gives no reflection to the viewer's eyes.
