On the first question, x in the graph does not represent the changes over time. It shows the time and year of the problem. The second question's answer is also false. The teta or angle of the question does not also represent the changes over time but the year it is being studied.
Answer:
hydrogen, oxygen, carbon and nitrogen
I did 4 instead :')
Explanation:
The structures are nephrons which gets blood through the [renal artery]. The nephrons also consist of the [afférent and efferent artérioles], the latter of which is much narrower causing a high pressure to exist in the [glomerulus] (blood vessels in that ball structure) so that ultrafiltration can occur and the ultrafiltrate is passed into the [Bowman’s capsule]. The Bowman’s capsule consists of podocytes which are cells that form a microscopic pore so that small molecules can pass through (ions and such). There is the [proximal convoluted tube] that makes the contents flow downwards (and allows water to exit so the water potential inside is low) and the [distal convoluted tube] that makes the contents go upwards (and allows water to re-enter which increases the water potential inside). These are both partially permeable and set up a concentration gradient for the reabsorption of water from the urine. These tubes lead into the [collecting duct] which further reabsorb the water.
All the structures of the kidney are in [ ].
Answer:
Observations at different distances show galaxies of different ages and therefore different stages of evolution. Observations of those different galaxies helps us to learn abt galaxy evolution because observations of distant objects reveal them as they were in the past.
