Answer;

-Sensation

Sensation is the activation of receptors in the various sense organs

Explanation;

-Sensation is the activation of sensory receptor cells at the level of the stimulus. Perception is the central processing of sensory stimuli into a meaningful pattern. Perception is dependent on sensation, but not all sensations are perceived.

-Receptors are the cells or structures that detect sensations. A receptor cell is changed directly by a stimulus. A transmembrane protein receptor is a protein in the cell membrane that mediates a physiological change in a neuron, most often through the opening of ion channels or changes in the cell signaling processes.

How have rising ocean temperatures affected coral communities?

Answer:

Explanation:Scientists predict that climate change will have many effects on freshwater and marine environments. These effects, along with nutrient pollution, might cause harmful algal blooms to occur more often, in more waterbodies and to be more intense. Algal blooms endanger human health, the environment and economies across the United States.

Climate Impacts That Might Affect Algal Blooms:

Warming water temperature

Toxic blue-green algae thrive in warm, slow-moving water.

Harmful algae usually bloom during the warm summer season or when water temperatures are warmer than usual. Warmer water due to climate change might favor harmful algae in a number of ways:

Toxic blue-green algae prefer warmer water.

Warmer temperatures prevent water from mixing, allowing algae to grow thicker and faster.

Warmer water is easier for small organisms to move through and allows algae to float to the surface faster.

Algal blooms absorb sunlight, making water even warmer and promoting more blooms.

Changes in salinity

Climate change might lead to more droughts, which make freshwater saltier. This can cause marine algae to invade freshwater ecosystems. In the southwestern and south central United States, toxic marine algae have been killing fish in freshwater lakes since 2000.

Higher carbon dioxide levels

Algae need carbon dioxide to survive. Higher levels of carbon dioxide in the air and water can lead to rapid growth of algae, especially toxic blue-green algae that can float to the surface of the water.

Changes in rainfall

Extreme storms followed by periods of drought can lead to more algal blooms like this one seen in Iowa in 2011.

Climate change might affect rainfall patterns, leading to alternating periods of drought and intense storms. This can cause more nutrient runoff into waterbodies, feeding more algal blooms.

Sea level rise

Scientists predict that sea level could rise up to one meter by the year 2100. This would create more shallow and stable coastal water, conditions that are perfect for the growth of algae.

Coastal upwelling

Coastal upwelling is the process by which winds push surface water offshore and deep water moves towards the coast, bringing nutrients from the ocean floor to the surface. Climate change is expected to alter the timing and intensity of coastal upwelling. Along the west coast of the United States, excess nutrients delivered by upwelling might lead to more algal blooms.

In Type I diabetes, the Beta cells of the pancreas produce little to no insulin. What effect does this have on an organism's abi

Sunny_sXe [5.5K]

With type 1 diabetes, beta cells produce little or no insulin. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. This buildup of glucose in the blood is called hyperglycemia. The body is unable to use the glucose for energy

What is the life cycle of a parasite in stages ?<br> Please help me thank you

tresset_1 [31]

Answer:

Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Explanation: The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism, trophically transmitted parasitism, vector-transmitted parasitism, parasitoidism, and micropredation.
