One of the events that could give credence to the panspermia hypothesis would be the presence of carbon-based molecules on meteors that strike the earth's surface.

<h3>Evidence of extraterrestrial lives</h3>

All biomolecules of life are carbon-based.  Examples of these molecules include carbohydrates, proteins, ribonucleic acids, etc.

In order for life to exist in a place, carbon must be abundant.

Thus, the presence of carbon-based molecules on meteors from another planet that hit the surface of the earth may be evidence that life exists on another planet.

This can be used as evidence that life on earth came from extraterrestrial sources.

Match each step of the scientific method with its description.

1- C ( this is an assumption; a hypothesis is always based on an assumption.

2- F ( this states to share the results with other classmates).

3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.

4- A (this is something you could observe during the experiment, therefore it is an observation).

5- E (this sentence is a conclusion).

6- B (This is an actual question)

What is the primary function of the juxtaglomerular complex?
Vsevolod [243]

Answer:

Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the  juxtaglomerular cells is to secrete renin in response to:

Stimulation of the beta-1 adrenergic receptor

Decrease in renal perfusion pressure (detected directly by the granular cells)

Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate

Explanation:

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.

*Fill in the blank*
Gekata [30.6K]

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released  as  ELECTRONS  move through the first electron transfer chain. This energy pumps HYDROGEN IONS  into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

  1. Luminous energy is trapped by chlorophyll in Photosystem II.
  2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
  3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
  4. <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
  5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
  6. <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
  7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
  8. The released energy is used to produce ATP molecules.
  9. Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
