positive feedback could be contractions(as painful as it may seem, its true) in child birth and the ripening of fruit.
negative feedback include the regulation of blood glucose levels and osmoregulation
The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.
<h3>Osmosis</h3>
Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.
The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.
On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.

Answer:
d. an immediate increase in the concentration of antibodies, followed by a slow decline.
Explanation:
The Primary Immune Response is mediated by antibodies, which are gamma globulin proteins formed by plasma cells (B lymphocytes). Plasmocyte is a differentiated B lymphocyte capable of actively secreting antibodies.
Antibodies are produced with the main function of neutralizing and eliminating an antigen that stimulated their production. This elimination process is done in various ways through complement fixation, opsionization, anaphylactic reaction (mast cell degranulation), substance neutralization, agglutination, etc.
To neutralize the antigen, the primary immune response promotes an immediate increase in antibody concentration. This is usually a quick process. This concentration usually begins to decline in a slow process, but it will vary depending on the antigen.
Answer:
Explanation:
Photosynthesis Vs. Respiration
1) Photosynthesis gets it's energy from sunlight, and uses the sunlight to change water and CO2 into energy. Cellular respiration gets it's energy from glucose molecules and oxygen.
2) Photosynthesis uses energy, CO2, and water to make energy and releases oxygen. Cellular respiration uses glucose molecules and oxygen to make energy, and releases CO2 and water.
3) Cellular respiration takes place in the mitochondria, and photosynthesis takes place in chloroplasts.
The highlighted vessels branch into arcuate arteries.
Arcuate arteries- The interlobar arteries bend over to produce imperfect arches at the point where the cortex and medulla meet. The arcuate artery is the name given to this portion of the blood supply as a result. The arcuate artery divides into several tiny radial arteries, which diverge at right angles and provide blood to the cortex.
Vessels- In the blood, vessels (canals) move waste away from organs and tissues and carry nutrients to those tissues. The vasculature's participation in oxygenating the organism serves as one of its main functions and important roles.
