I would say teh cytoplasm and nucleus.
It illustrates the cycling of matter, just like in a natural ecosystem.
Option D.
<h3><u>Explanation:</u></h3>
The natural stable ecosystem is defined as the ecosystem which has the members doing their part of job and each and every member contribute to the stability of the ecosystem by completing food chains.
Here in this bottle ecosystem the boy put the stones, rocks, water which gives proper nutrition to the growing plants and animals which are also introduced by the boy. The plants produce oxygen and consume carbon dioxide whereas the animals consume oxygen and produce carbon dioxide. Thus the cycle is maintained and stability is achieved.
Answer:
Explanation:
1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.
2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.
3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.
Wave of option A has the highest frequency.
Option A.
<h3><u>Explanation:</u></h3>
Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.
In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
