Answer:
A. Salivation at the sound of a bell
Explanation:
It is correct on PLATO
Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
Answer:
Articular articular cartilage is very important part of the long bone structure. It is present between the bones at the joints and help in reducing the friction between the joints. the epiphytes is data present at the end of the long bones are usually have a covering of the articular cartilage and it has a very thin layer of cartilage that helps in reducing the friction .
It also act as a shock absorber between the two bones and helps in the transmission of force from one phone to another and divide the force across the skeletal system. It also transmit the force on the bones with low fictional coefficient. The articular cartilage are very susceptible and prone to the injury and it lacks blood vessels and nerves. Articular cartilage is made up of hyaline cartilage and is made up of densely packed extracellular matrix which certain type of specialised cells known as chondrocytes. It is also made up of water , collagen , proteoglycans and glycoproteins .
The professional that most likely will be called in to help seismologist.
<h3><u>
Explanation:</u></h3>
When an underwater earthquake has just been recorded in the middle of the Pacific Ocean, the seismologists will be called to determine if the effects of this earthquake and whether or not it will cause tsunamis off the coast of Hawaii.
Seismology is the study of earthquakes, the escalation of waves and the effects they might have. A seismologist is a scientist who is concerned with these studies. They make use of seismographs and other relevant tools to gather essential data which helps in reading the planetary movements and understanding them better. The study does not always predict an earthquake but it helps in predicting the possibility of tsunamis. Seismology enabled the development of tsunami warning systems.
Answer:
B
Explanation:
I believe it is meiosis because there are two parts in which it helps to increase genetic variety. In prophase 1, the genes cross over, which increases the variety. Also, the chromosomes are assigned randomly in Metaphase 1.
Hope this helps:)
