The answer would be A. 500g because the candle would not lose mass despite being melted. Melting the candle is only a physical change and not a chemical change resulting in no change in the mass.
<h2>Messenger RNA
</h2>
Explanation:
Messenger RNA results from the breakage and recombining of DNA strands that is known as transcription
- Transcription always starts at a specific site called promoter
- Promoter are specific sites on DNA where RNA Polymerase binds and initiates transcription
- Synthesis of RNA occurs in 5'-3' direction and continuous
- Only a strand of DNA act as template, template is also known as antisense strand or non coding strand
- The complementary strand is the sense strand or the coding strand
- Only a small segment of DNA is transcribed at a time generally called gene
The most vocal reptile ARE THE CROCODILES.
Crocodiles use different types of calls, smells and water behavior to communicate with one another. Scientists have discovered that some species of crocodiles can pass across up to twenty messages using sound alone. The sounds made can be used to signify threat, distress or it can be used to attract others for courtship purpose. Crocodiles also communicate through smells and through water behaviors.
Answer:
b. Mitochondrial respiration
Explanation:
Mitochondrial respiration of plants involves the participation of two major electron transport routes:
1. Cytochrome c oxidase route: cyanide sensitive and coupled to three energy conservation sites.
2. Cyanide-insensitive alternative route: involves alternative oxidase (AOX), branches off the cytochrome oxidase route into the ubiquinone pool, with no energy conservation thereafter as AOX is able to directly oxidize ubiquinol and reduce oxygen to water.
Regardless of the route followed, mitochondrial breathing is a long and complex process. However, it is through this breath that at a given moment electrons are passed to oxygen through a carrier channel in the inner mitochondrial membrane. This happens when cytochromes to and some molecules that have a heme group (with an iron atom) and are linked to a transmembrane protein that connects the matrix to the mitochondrial intermembrane space and have two copper atoms that allow the transport of electrons to the final acceptor, oxygen (O2).
The PAX-6 gene is a gene that translates to the PAX-6 protein that serves as a transcription factor needed to activate certain genes that functions in the development of the eyes. While PAX-6 gene may look like it produces different functions for different species (such as formation of the compound eye in insects vs. formation of a single lens eye in vertebrates), it does not. It does in fact only regulate the genes required for the formation of the eyes. Absence or mutation of the PAX-6 gene will cause aniridia or absence of the iris, opaque lens and cornea, and a dysfunctional retina. Also, the function of the PAX-6 protein is conserved throughout evolution of species.
