Answer:
The mRNA leaves the nucleus and travels to the ribosome where proteins are synthesized
Explanation:
During transcription, a messenger RNA (mRNA) molecule is synthesized from a specific DNA region which is referred to as a gene. Subsequently, the mRNA leaves the cell nucleus through the nuclear pores of the nuclear membrane and travels to the ribosome, where this sequence serves as template to synthesize a protein, in a process known as translation. Within the ribosomes, triplets of consecutive RNA nucleotides called codons bind to complementary RNA nucleotides (called anticodons) of the transfer ribonucleic acids (tRNAs). Each tRNA attaches a specific amino acid that corresponds to its anticodon sequence, which is then added to the nascent polypeptide chain.
Explanation:
Porosity depends on the size, shape, and mixture of grains and particles that compose soil and rock. For instance, small particles such as clays can compact more closely together, reducing the amount of porosity. However, larger particles such as sand and gravel will have more spaces available between them.
1) Its an educated guess
2) the definition of the word "hypothesis is "testable".
3)a testable proposition explaining the occurrence of a phenomenon or phenomona, often asserted as a conjecture to guide further investigation.
Answer:
Yes. Due to the magma in the mantle, the tectonic plates in the upper crust of the earth move because of a process called *convection. The heat from the magma causes the tectonic plates to move at a very very slow rate
*An example of this is when you're cooking food in a pan. The food is getting hotter because the heat rising from the stove heats the pan.
In simpler terms: Stove ~~ Pan --> hot food
*There is no direct contact between the stove and the pan which is a defining feature of convection.
Ans: A change in the number of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.
