Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.

skin
Explanation:
this is one of them. it has a sense of touch skin is a organ
Calvin cycle i’m pretty sure
Answer:
<em>Organisms that are eaten by the mayfly will increase.</em>
<em>Organisms that eat mayfly will decrease at first.</em>
<em>Organisms that eat mayfly would consume more of other organisms in their diet</em>
Explanation:
her get killed or they will migrate from the stream that is polluted. The population of the organisms on which the mayfly larva fed would increase as it will have a lesser number of predators now.
On the other hand, the organisms which fed on the mayfly would decrease at first as they will have a lesser amount of food available. They might find another source of food in order to survive.
Answer:
As a new covalent connection develops between the two glucose molecules, one loses a <em>H group,</em> the other loses an<em> OH group</em>, and a <u>water molecule is freed</u>.
<h2>
Why does glucose form a polymer despite being a stable molecule?</h2>
The formation of glucose polymers (glycogen, starch, cellulose) requires the input of energy from uridine triphosphate (UTP). Any tiny molecules must be converted into bigger molecules, which is compatible with the second rule of thermodynamics. Building proteins from amino acids, nucleic acids from nucleotides, fatty acids and cholesterol from acetyl groups, and so on are examples. Energy is released when bigger molecules are broken down into smaller ones, which is compatible with the second rule of thermodynamics. Thus, glucose may be converted to CO2 and H2O, resulting in the production of ATP. While glucose is a tiny molecule and hence relatively "stable," it can exist at a potential energy level and may be used to build up (needs energy) or broken down (<em>produces</em> energy). All of these biochemical processes require the use of enzymes; otherwise, the activation energy of most reactions would require extremely long periods of time for random energy inputs to push the reactions in either direction, despite the fact that energy considerations favor spontaneous breakdown over synthesis.
