Compare and contrast an active solar heating system with a radiator system.
Answers
Answer:
A system that uses the sun's energy without requiring mechanical devices (pumps or fans) to distribute the collected heat are called solar system while radiator system uses fuel to heat the water. in active solar heating system, the SUN's energy used to heat water.
The comparison of an active solar heating system with a radiator system gives; Solar systems use the sun's energy to heat water without the need for mechanical equipment to disperse the heat, where radiator systems require fuel to heat the water.
What is an active solar heating system?Active solar heating systems employ solar energy to heat a fluid (liquid or air), which is then transferred to the interior area or stored for later use.
In conclusion, an active solar heating system and a radiator system are all subs of heat energy

Say that you look at the nuclei of 100 skin cells taken from the same person. About how many of these skin cells would you expect to be in interphase
Answers
Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

muscle strains are most often located:

under the surface of the muscle.
in the middle section of the muscle.
where the muscle meets the tendon.
Answers
Answer:
where the muscle meets the tendon.
Explanation:
I put the answer above and I got it wrong so this is the correct answer!!
:)
Muscle strains are most often located where the muscle meets the tendon. Therefore, the correct option is D.
Stretching or tearing of muscle fibers can occur when a muscle stretches or contracts suddenly or excessively. This often occurs at the musculotendinous junction, where the muscle attaches to the tendon. The area where the tendon meets the muscle is particularly prone to strain, because of the significant stress and tension that occurs there during muscle contractions and movements. Depending on the degree of muscle fiber damage, the intensity of a strain can range from mild to severe.
Therefore, the correct option is D.

The Chaparral practice - QuizletWhat would happen to the DNA molecule if the pairing was non-complementary, in other words, the two purines (adenine and guanine) paired with one another and likewise the two pyrimidines (thymine and cytosine) paired with each other.
Answers
If the base-pairing in DNA becomes non-complementary such that purine bases can pair with one another and pyrimidine bases can pair with one another, the 1:1 ratio of purine to pyrimidine bases in DNA will no longer hold.
Due to the complementary base-pairing rule, the ratio of purine to pyrimidine bases in DNAs is usually 1:1. This is because Adenine always pairs with Thymine while Guanine always pairs with Cytosine.
Once this base-pairing rule is removed and becomes purine-purine and pyrimidine-pyrimidine pairings, then it becomes unnecessary for the ratio of purine to pyrimidine bases to be 1:1.

An individual with androgen insensitivity syndrome will:
A. Not be feminized at puberty
B. Prefer a female sexual partner
C. Not function sexually as an adult
D. Have female external genitalia
Answers
Answer:
D I think. i am not completely sure.
An individual with androgen insensitivity syndrome will have female external genitalia, which is option D, as androgen insensitivity syndrome (AIS) is a genetic condition in which an individual's cells are unable to respond to androgens.
What is androgen insensitivity syndrome?Androgen insensitivity syndrome (AIS) is a genetic disorder in which an individual's body is unable to respond properly to male sex hormones, called androgens. The condition is caused by mutations in the gene that codes for the androgen receptor, which is a protein that binds to androgens and enables them to activate certain genes. In individuals with AIS, the androgen receptor either doesn't work at all or doesn't work properly, which leads to a range of physical changes that can vary in severity depending on the degree of androgen insensitivity.
Hence, An individual with androgen insensitivity syndrome will have female external genitalia, which is option D.
