Answer:
Prokaryotic cells are single-celled organisms that lack membrane-bound organelles and eukaryotic cells contain membrane-bound organelles.
Prokaryotic cell lack nucleus and its genetic material is circular in form which is present in its cytoplasm while eukaryotic cell has a membrane-bound nucleus which contains linear DNA.
Prokaryotic cells might have been the first ones to evolve because prokaryotic cell is simple in organization while eukaryotic cell are more complex.
Eukaryotic cells contain some organelle like mitochondria and chloroplast which resembles the prokaryotic cell because both have linear DNA and 70s ribosome.
So it supports endosymbiotic theory which says that a large prokaryotic cell engulfs a small prokaryotic cell and both remained in symbiotic association with each other and evolved to form eukaryotic cells.

Which condition feeds a tropical storm as it develops into a hurricane? A. heat and moisture B. cool temperatures and rain C. high temperatures and freshwater D. wind and dry air
Hurricanes form over tropical waters (between 8 and 20 degrees latitude) in areas of high humidity, light winds, and warm sea surface temperatures [typically 26.5 degrees Celsius (80 Fahrenheit) or greater]. These conditions usually prevail in the summer and early fall months of the tropical North Atlantic and North Pacific Oceans, and for this reason, hurricane “season” in the northern hemisphere runs from June through November.
The first sign of hurricane genesis (development) is the appearance of a cluster of thunderstorms over the tropical oceans, called a tropical disturbance. Tropical disturbances generally form in one of three ways, all of which involve the convergence of surface winds. When winds come together (converge), the force of the collision forces air to rise, initiating thunderstorms.

The underwear in the image keeps you warm on cold nights because it A) keeps cold air out. B) is a poor insulator. C) is a good insulator. D) is a good conductor.
Prevents Conduction
Answer:
Option C, is a good insulator
Explanation:
See the attached image of the underwear
Solution
As it is clear in the image, the fabric of the underwear is poly fabric which acts as a good insulator.
Being an insulator, it can easily trap the heat of the body during winters and does not allow this heat to escape due to which it is successful in keeping a person warm during the winters.
If the material of the underwear would have been a conductor, it would have allowed heat of the body to escape.
Hence, option C is correct
What are thin and thick myofilaments made of?
Thin myofilaments are made up of the protein actin, meanwhile thick myofilaments are composed of the protein myosin. These two are key players in muscle contraction.
Explanation:In muscular biology, the terms thin and thick myofilaments reference the protein structures that enable muscle contraction. Thin myofilaments are primarily composed of the protein actin, along with two other proteins, tropomyosin and troponin. Thick myofilaments, conversely, are made of another protein called myosin. These myofilaments slide past each other to cause muscle contraction, a process known as the sliding filament theory.

The mutation will cause a translocation to occur.
The mutation will cause a change in the individual but it will not be inherited.
The mutation will be inherited by the offspring.
The mutation will not cause any change in the individual and it will not be inherited.
Hi,
If a point mutation occurs during which CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.
This is because, both AGA and CGA code for same amino acid called Arginine.
We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism

Which process occurs during asexual reproduction? A. Crossing-over between homologues B. Mutation C. Separation of homologous pairs of chromosomes D. Separation of sister chromatid
A. Crossing-over between homologues.
Explanation:In meiosis and mitosis, recombination happens between comparable particles of DNA (homologous groupings). In meiosis, non-sister homologous chromosomes pair with each other so recombination ordinarily occurs between non-sister homologs.
All living organism reproduces either through asexual reproduction or sexual reproduction or sometimes through both mode of reproduction. In both cases let it be sexual or asexual, the mode of cell division namely meiotic and mitotic cell division, the recombination between homologous chromosomes is a typical system utilized in reproduction.

Which abnormal skin growth results from a virus?
freckles
moles
warts
jaundice
Warts are the abnormal skin growths that result from a virus. While freckles, moles, and jaundice are also skin conditions, they are not typically caused by a virus. Instead, each has different causes such as sun exposure, genetics, and high levels of bilirubin respectively.
Explanation:The abnormal skin growth that results from a virus is a wart. Warts are rough, usually skin-colored growths that appear on the skin and mucous membranes. They are caused by the human papillomavirus (HPV). The virus infects the top layer of the skin and causes it to grow quickly, leading to a wart. While freckles, moles, and jaundice can also be familiar terms related to skin conditions, these are not typically caused by a virus.
For instance, freckles aren't caused by a virus but are small, brownish spots on the skin that can appear as a result of sun exposure and genetics. Moles, which are small skin marks caused by pigment-producing cells in the skin, are mostly harmless and aren't typically caused by a virus. Meanwhile, jaundice is a result of high levels of bilirubin in the body and causes a yellowing of the skin and eyes, but it is not related to a viral infection.

If the ductus deferens tubes are cut and tied (vasectomy), the semen will not contain select one:
a. fructose.
b. buffers.
c. mucus.
d. sperm.
e. all of these.
If the ductus deferens tubes are cut and tied, the semen will not contain sperms. This is known as vasectomy. This procedure is performed in males to control population. Thus, the correct option is D.
What is Vasectomy?
Vasectomy is the permanent male sterilization procedure. It is a surgical procedure which involves the cutting or sealing of the ductus deferens tubes which carries a man's sperm to permanently prevent pregnancy. It is usually carried out by giving a local anesthetic to the client, where the man is awake but could not feel the pain, and this procedure complete in about 15 minutes.
Once the tubes are cut, sperms cannot enter into the semen of man or out of the body. However, the testes do produce sperms, but the sperms die and absorbed by the body. A man who have undergone a vasectomy still produces the semen and is also able to ejaculate it. But, the semen contains everything except sperms.
Therefore, the correct option is D.
