Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
True!!
Eukaryotic DNA never leaves the nucleus; instead, it's transcribed into RNA molecules, which may then travel out of the nucleus.
Answer:
Explanation:
Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.
While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).
practice with people (parents, friends, siblings) and ask them to ask questions during it so you can learn how to keep focus and memorization, or practice in front of stuffed animals. read it out loud on recording, then practice saying it with the recording without the words in front of you. you'll do great! :)
<u>In the process of translation, the statement stands correct and applies are as follows:</u>
- The ribosome has two sub-units that work together.
- Amino acids are joined by peptide bonds.
- Each tRNA brings in exactly one amino acid that corresponds to the anti-codon.
- The order of the amino acids is determined by the mRNA which is transcribed from DNA.
Answer: Options A, B, C, and E
<u>Explanation:</u>
In the process of translation, ribosomes are the structural unit where the translation is being performed and it has the two sub-units which enact together the translational process.
Any two amino acids are bonded together by peptide bond and tRNA brings one amino acid at a time which corresponds to the anti codon. The order of amino acids is determined by mRNA transcribed from the DNA, and not from the ribosome. Thereby, all given options are correct except the option D.
