The circulatory and skeletal systems work together in the following way: skeletal system produces cells in the bone marrow while the circulatory system transports cells where they need to go (option A).
<h3>What is skeletal and circulatory system?</h3>
Skeletal system is the system that works as a support structure for your body. It gives the body its shape, allows movement, makes blood cells, provides protection for organs and stores minerals.
Circulatory system, on the other hand, are parts of an animal body comprising the heart, veins, capillaries and arteries. It circulates blood and lymph through the body.
According to the above description of both systems, the skeletal system produces blood cells in the bone marrow while the circulatory system transports these cells.

Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.
Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light
Answer:
PROMOTER is a DNA sequence where RNA polymerase binds and begins the process of transcription. ENHANCER is a D N A sequence that binds regulatory proteins that interact with promoter-bound proteins to activate transcription.
Explanation:
