Answer:
Cancer disease occurs when the abnormalities occurs during cell division of stem cells. Stem cells are those cells which are produced in the body and used by the body when the cells are older or get damaged. When the division of these stem cells are uncontrollable, cancer occurs which spread to the surrounding cells. When a large group of cancer cells grow in size, it turns into tumor.
A) TAGGATCTTCCA
b)GCAACGTCTTGA
c)ATGCCTAGCAGT
Answer - B
Fish and reptiles both are ectothermic but fish have gills and reptiles have lungs. Ectothermic organisms do not have an internal mechanism of regulating their body temperature and are dependent on their atmosphere for temperature regulation. Fish, reptiles and invertebrates are examples of ectothermic organisms.
1. The Cell Wall.
Plants have a cell wall in order to maintain rigidity and stability. Animal cells do not have a cell wall because they have a different structure, which makes them more flexible and able to move around easier.
2. Chloroplasts
Since plants cannot move, they get their energy from the sun. This energy is made inside of the chloroplasts. Animal cells don't have chloroplasts because their energy comes from other organisms.
3. Central Vacuole
The central vacuole provides structure and holds materials and wastes, and also decomposes those wastes. Animal cells don't have a central vacuole because they have lysosomes and normal vacuoles that do the same function.
1) Both involve electron transport chains.
<span>2) Chemiomosis allows ATP synthase to produce ATP. </span>
<span>3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.) </span>
<span>4) Both utilize ATP for energy at some points. </span>
<span>5) Both provide power for cellular activities. </span>
<span>5 Differences </span>
<span>1)Cellular respiration depends on oxygen as a substrate. </span>
<span>2)Photosythesis utilizes 2 electron transport chains (not just 1). </span>
<span>3)In Photo. , energy is provided by photons and not catabolic processes as in cell. resp. </span>
<span>4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2) </span>
<span>5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).</span>
