B. sexual selection, which alters allele frequencies in the gene pool.
Secretion is similar to Reabsorption because in both substances cross endothelial cells lining the glomerulus and epithelial cells of Bowman's capsule.
Secretion is the movement of the molecules which are selective from the blood and then added to the filtrate in the tubule lumen by an active process. The secretion process enhances excretion by removal of the solutes from the peritubular capillaries.
Reabsorption is a process of movement of the substances in filtrate from lumen of proximal tubule back to the blood which flows through the peritubular capillaries and the cells of the proximal tubule transport the solutes out of the lumen and then water follows through the process of osmosis.
Answer:
1. Chlorophyll absorbs light
2. Water split to start electron transport chain
3. ATP produced
4. ATP used to build glucose form carbon dioxide
Explanation:
Photosynthesis is the process whereby green plants synthesize their food (glucose) in the presence of sunlight. This photosynthetic process occurs in two major stages viz: light dependent and light independent phases.
In the light dependent phase, the following occurs sequentially:
- Chlorophyll absorbs light energy from sun
- The energy is used to split water molecule in a process called PHOTOLYSIS OF WATER in order to start electron transport chain.
- The electron transport chain yields ATP and NADPH, which will be used in the next phase.
In the light independent phase, also called, CALVIN CYCLE, ATP is used to power the formation of glucose from carbon dioxide
Answer:
The cork cambium is a natural insulator that protects woody plants from an hostile environment.
Explanation:
The cork Cambium is a tissue that belongs to the epidermis, it is responsible for the secundary growth in the plant and replaces the epidermis in roots and stems. The cork cambium also protects the plant from overhydration, it is waterproof and has really selective ways to let the water into the plant (apoplastic and symplastic pathway).
There is some special plants in the coast of the tropical area called mangrooves, these plants has really specialized cork cambium that controls not only the water levels but also the salt levels into the plant.
The cork cambium is really important because protects and regulates the plant and its environment.
My best guess would be B. Hope this helps! ^_^
