Describe how the integumentary system responds to differences in sunlight

Biology
1 answer:
Mama L [17]3 years ago
5 0

The integumentary system (skin) reacts different on different sun intensity (different length exposure to sun).

For example, moderate exposure to the sunlight contributes to the production of melanin and vitamin D by the body. On the other hand, high exposure to sunlight can have negative health effects such as sunburn, which is an inflammatory response to DNA damage caused by UV radiation.

Answer:

Signal transduction pathways

Explanation:

Plant hormones act by directly affecting the activities of signal transduction pathways.

Signal transduction pathways are involved in the transfer of signals from outside of the cell to the inside of the cell for the regulation of various cellular activities. For this, the extracellular signalling molecules bind to the receptors that are located on the cell membrane. After their binding due to some change in the receptor molecule, a signal is triggered in to the cell and thus information from outside of the cell is transferred to the inside of the cell through these transduction pathways.

Plant hormones affect these pathways and as a result membranes, enzymes, and genes are also influenced by the plant hormones.

Which process allows organisms to use nitrogen based molecules
Maurinko [17]
Fixation
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria

Compare what ways are planets and<br> dwarf planets similar.
Cerrena [4.2K]
So the similarity of the planets and the dwarf planets are they are both mostly round because they have sufficient gravity to flatten their own surfaces into a sphere. The differences are that planets are big enough to clear the whole region of space where they orbit the sun whereas dwarf planets do not.

In normal skeletal muscle tissue, binding of acetylcholine to its receptors at the neuromuscular junction results in:
BARSIC [14]
<span>Answer: Opening of Na+ and K+ Explanation: Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential. Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>
