I think the correct answer from the choices listed above is the second option. Lysosomes can be compared to the recycling and garbage centers of a city. This can be justified since they <span>digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.</span>
<u>Answer:</u>
<em>Six centromeres are observed in a prophase cell from an insect, there are </em><u><em>20 pairs of chromosomes present</em></u><em>. </em>
<u>Explanation:</u>
<em>Centromeres is defined as the part of the DNA</em> which are held responsible for the directional changing of chromosomes.
And these chromosome gets divided into <em>2 daughter cells while undergoing the process of mitosis and meiosis. </em>
<em>Chromosome is basically defined as a thin structure</em> as of a threadlike which is made out of nuclei acid and protein which is <em>located at the nucleus of various living cells</em>
An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the
basis of limited evidence as a starting point for further
investigation.
And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general
theory
.The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.
Cells are made up smaller units called organelles that undertake various critical roles in the activities of the cell. Some of these organelles include, mitochondria whose major function is formation and production of energy in the form of ATP, Ribosome is an organelle involved in the protein synthesis, lysosome is involved in the destruction of old and worn out tissues and organelles, Golgi apparatus or complex helps in transportation, modification and packaging of secretions such as proteins and lipids. Therefore, alcoholism affects the activity of lysosomes in the liver since they are tasked in the digestion of proteins using hydrolytic enzymes.
