Answer:
Using the number of amino acid differences, it would appear that the two birds are more closely related (had a common ancestor very recently), while the two fungi would have to trace their common ancestry much farther back in time (much more distantly related).
Answer:
As the type of investigation is not discussed, lets answer the question generally.
Explanation:
One of the properties of water is that water in the form of ice is less dense as compared to water liquid water. This property of water lets fishes survive in conditions when the temperature is freezing.
The hydrogen bonds in water make the water turn into a vast, honeycomb structure when the temperature is below 4 degrees Celsius. This causes the ice to float on water and the fishes can stay alive in the liquid water underneath the ice.
Answer:
c. One half as much.
Explanation:
The amount of genetic information contained in a normal human sperm cell (23 chromosomes) is one-half as much the information contained in a normal human body cell (46 chromosomes). Sperm cells are produced during meiosis, a specialized division process that <u>reduces the number of chromosomes in half</u>, generating haploid daughter cells.
Answer:
The correct answer is d Lysosomes contain enzymes to breakdown damaged cellular material.
Explanation:
Lysosomes are called digestive organelle that contain many hydrolytic enzymes such as acid hydrolase ,peptidase, nuclease etc which aids in the digestion of various cellular components such as carbohydrates,protein,nucleic acid.
Lysosome perform the same function by the formation of auto phagolysosome which contain the those cellular molecules and organelles those are targeted for degradation.
The answer is
B. Denaturing proteins
C. Altering quaternary structures
D. Destroying cell membranes
Protein have a complex structure from primary to quaternary structure. Change in pH or temperature will cause denaturation of protein which make it unfolded and change the secondary, tertiary, or quaternary structure and cause the enzyme of bacteria become useless. It could also damage the protein in membrane and destroy them, causing lysis. It should not affect the sugar though
