Biology
1 answer:
damaskus [11]3 years ago
8 0

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.

imagine that you could treat chloroplats with an indiicator dye that turns red in acidic conditions, yellow in neutral ocndition
zmey [24]

The amount of light between points 1 and 2 is adequate for photosynthesis to occur at a faster rate than cellular respiration. Acidic conditions typically imply that the solution has an excessive concentration of H+, which makes the solution acidic. By dividing the reaction into half-reactions, the balancing process begins.

This indicates that more CO2 is being consumed than is being produced, which makes the problem more straightforward.

The signal will become purple as a result, from yellow. After point 2, light levels are low enough that cellular respiration outpaces photosynthesis, which results in more CO2 being generated than being absorbed and raising the pH of the solution. The indication will become yellow as a result, from purple.

An indicator dye called bromothymol blue (BMB) changes color from blue to yellow when acid is present. The pH of the solution decreases when carbon dioxide is introduced because it produces carbonic acid. When the pH is greater than 7.6, green, between 6.7 and 7.6, and yellow, less than 6, BMB is blue.

<span>The heart contains four chambers: upper left atria, upper right atria, lower left ventricle and the lower right ventricle. Oftentimes, the right atria and right ventricle are together referred to as the "right heart" and the left atria and left ventricle are referred to as the "left heart", however there are still four separate chambers.</span>

3) which statement most succinctly sums up the general function of an enzyme?
klemol [59]

Answer:

3) The correct answer would be the third option.

Enzymes are biocatalysts which increases the rate of a biochemical reaction is decreasing the activation energy required by the reaction.

The substrate binds to the active site of the enzyme to form an enzyme-substrate complex. It is then converted to enzyme-product complex. Lastly, the product is released and the enzyme is ready for a new cycle of reaction.

4) The correct answer would be cohesion.

Cohesion or cohesive force refers to the attractive force by which like-molecules are stick together.

For example, water molecules are stick together to form droplets.
