Answer: With a fingerprint a family can check their genetic makeup.
Explanation:
DNA fingerprinting is a chemical test that shows the genetic makeup of a person or other living things.
Answer:
excitable
Explanation:
All muscle types will respond to an electrical stimulus because all muscle cells are excitable.
Excitability is response of muscle to signal which delivered through the motor neuron.
Excitability is stretching of muscles.
The contraction and relaxation of muscle occur in following way:
Muscle contraction begins with signal. The contraction occur when nervous system send signals. The impulse which is called signal is travel through a motor neuron.
The whole process include following three steps:
1) Message is traveled from nervous to muscular system and trigger the chemical reaction.
2) This chemical reaction causes the muscle fibers to reorganize in such a way that shorter the length of them which is called contraction.
3) when this signal is no longer remain , reverse chemical process occur and muscles relax.
<span>The polymer that provides plants with their genetic traits is nucleic
acid. The answer is C. Nucleic acids are what made the DNA (deoxyribonucleic
acid). The DNA are composed of a nitrogenous base, phosphate and a sugar
(deoxyribose). The bases are adenosine, tyrosine, uracil and guanine. And they
are needed to be matched to carry the trait. The nitrogenous base is the traits that
contains the genetic material and are mostly composed of nucleic acids. </span>
Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
