because it's too far away. you can however see some large structures like the great wall of China from space

<em><u>Explanation:</u></em>

It's the same thing as saying, why can't I see a atom with my bare eye???

The trees and cities are just WAY too small and far away for us to see if we were in outer space.

Adenylate cyclases (ACs) are the membrane-bound glycoproteins that convert ATP to cAMP and pyrophosphate.
sasho [114]

Adenylate cyclases (ACs) are the membrane-bound glycoproteins that convert ATP to cAMP and pyrophosphate.

When activated by G-protein Gs, adenylate cyclases (ACs), which are membrane-bound glycoproteins, catalyze the synthesis of cAMP from ATP.

Different AC isoforms are widely expressed in various tissues that participate in regulatory systems in response to particular stimuli.

Humans have 9 different AC isoforms, with AC5 and AC6 thought to be particularly important for cardiac activities.

Nitric oxide has an impact on the activity of AC6, hence the protein's nitrosylation may control how it works. However, little is known about the structural variables that affect nitrosylation in ACs and how they relate to G's.

We predict the cysteines that are prone to nitrosylation using this 3D model, and we use virtual ligand screening to find potential new AC6 ligands.

According to our model, the AC-Gs interface's Cys174 in G's and Cys1004 in AC6 (subunit C2) are two potential residues that could experience reversible nitrosylation.

How is The environment on Mars different from that of Earth’s?
Pavlova-9 [17]

Answer:

  • Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth's. The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide.
  • The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth's is rich in nitrogen and oxygen.
  • Because of the differences in atmospheric densities and distances from the sun, the temperature within the atmosphere are also wildly different. Earth generally ranges from 14 degrees Celsius to 70.0 degrees, whereas Mars ranges from -146 degrees C to -140 degrees C.
  • Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.
  • Earth and Mars’ both have terrains that varies considerably from place to place.

Can amoeba have offspring with different genes and traits
stepan [7]

Here is your answer

No

______________________________

REASON:

Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.

Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.

However in some case due to genetic drift or mutation, slight variations can be found in progeny.

But this is very exceptional.
