Prokaryotic Cells = do not have a nucleus; generally smaller and simpler that Eukaryotic cells.
-Smaller
-does NOT have a Nucleus
-translates to ‘no Nucleus’ OR ‘no true Nucleus’
-simpler
-they don't have all of their genetic material bound in a nucleus, which is why they are simpler forms of life.
-Prokaryotic cells do have genetic information but it is just stored differently
Ex: Bacteria and Single-Celled organisms
Eukaryotic Cells = Contains a Nucleus and are usually larger and more complex than a Prokaryotic cell
-Bigger
-DOES have a Nucleus
-More Complex
-Specialized to do certain things
Ex: All the Cells in a Human’s body. Skin cells, Red Blood cells
Answer and Explanation:
The interphase is the previous step before mitosis occurs. The interphase is conformed of the G1, S, and G2 stages.
- During the G1 stage, it occurs a high intense biochemical activity. The cell duplicates its size, and the organelles and other molecules and cytoplasmatic structures duplicate too. Some structures, such as microtubules and actin filaments, are synthesized from zero. The endoplasmic reticulum increases in size and produces a membrane for the Golgi apparatus and vacuoles, lysosomes, and vesicles. During this stage, the pair of centrioles separate, and each centriole duplicates. Mitochondria and chloroplasts also replicate.
The stages S and G2 follow the G1. Once the whole interphase is completed, mitosis occurs.
- During the S stage occurs the DNI replication process. At this point, it also occurs the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
- G2 stage is the final one before the cellular division. Here it begins the slow process of DNI condensation. Duplication of centrioles completes. Structures such as spindle fibers are assembled.
Answer:
Ectotherms warm their bodies by absorbing heat from the surrounding environment, whereas Endotherms produce heat by their metabolic activities. • Ectotherms have large variations in normal body temperatures while endotherms maintain their body temperature in a fairly constant value
Explanation:
Answer:
Lots of bacteria are present as the microflora of a baby's gut which helps it to extract the nutrition from mother's milk and also helps the baby to maintain a low number of pathogenic bacteria in its gut.
Some bacteria present in the baby gut release enzymes like glycoside hydrolase which helps baby to digest carbohydrate present in the mother's milk.
Bacteria like Bifidobacterium, Streptococcus, Staphylococcus are already present in breast milk which helps in making gut microflora of baby and this gut microflora helps in extracting nutrients from mother's milk.
