How do amounts of green pigment,chlorophyll, different from summer to fall

Biology

Okay, so we know that leaves get their green color from a green pigment called chlorophyll. During the summer, leaves are very green and then during the fall leaves tend to be brown, orange, and yellow. This is because the amount of chlorophyll is a lot less in the fall. The chlorophyll is breaking down during this time of the year, which gives the leaves a brownish color.

In summer, the amount of green pigment and chlorophyll are much more, in fall, the amount of chlorophyll and green pigment is less. That's the reason the leaves turn colors.

Identify the substances that can readily pass through the inner mitochondrial membrane.
KIM [24]

Answer:

A,C E

Explanation:

The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated  folded inwards  to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.

The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix

These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy  for phosphorylation of ADP by  P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.

O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation  and ETC will nor occur.

CO2 must pass through because its accumulation will increase the acidity of the inner  mitochondria

C.Glucose

The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.

As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.

Is it possible for an individual with X-linked agammaglobulinemia to develop rheumatoid arthritis?
trasher [3.6K]

Explanation:

so X-linked agammaglobulinemia (XLA) is a rare genetic disorder discovered in 1952 that affects the body's ability to fight infection. As the form of agammaglobulinemia that is X-linked, it is much more common in males.

So in rheumatoid arthritis Typically, stiffness begins in the joints of the hands. It usually comes on slowly, although it can come on suddenly and affect multiple joints over the course of one or two days... I hope this helped you answer your question :)
