Answer:
A
Explanation:
Near the nucleus, Centrioles are primarily used to assist in the division of cells
Usually to study genetics mendel used pea plants because of the easy traits associated
B. ventricles
The chordae tendinae, also referred to as heart strings, are tendons that connect the atrioventricular (tricuspid) valves to the muscular wall of the heart. These chords are made predominantly of collagen, while the remaining part is elastin. They play the vital role of maintaining the structure of the valves they connect to. Due to the high pressure generated within the heart, it is entirely possible for the atrioventricular valves to turn inside out. The chordae tendinae prevent this from happening and keep the valves functioning properly.
Answer: Option 4.
The fresh water is hypotonic and the salt solution is Hypertonic.
Explanation:
Hypotonic solution is a solution that have little dissolved solutes i.e low osmotic pressure compare to other solution. When a cell is put in hypotonic solution, it take in water and the cell swell up and it does not burst due to it's cell wall thereby becoming turgid or hard.
Hypertonic solution is the solution where the concentration of solute is higher outside the cell than inside the cell. Example is saline water.when a cell is placed in Hypertonic solution it will shrinks because it losses water.
Answer:
RNA
Explanation:
Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.
The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).
The mRNA is then used as a template for amino acids synthesis during translation.
