Answer:

588 m^2

Explanation:

From the illustration, the surface area is given by the formula:

Surface area = 4πr2, where r is radius and π is a constant with a value of 3.

Then, if for a sphere, r = 7 m, the surface area becomes:

Surface area = 4 x 3 x 7 x 7 = 588 m^2

<em>The surface area of a sphere with a radius of 7 meters is therefore 588 </em>m^2<em />

Earth is special because it is an ocean planet. Water covers 70 percent of Earth's surface. Earth's atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe.There are multiple reasons for earth to be a special planet. Reasons are as follows

1.Earth is the only planet known where intelligent life exist.

2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.

3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.

4. Earth has Van Allen radiation belts which protects it from cosmic rays.

5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.

6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.

7. Tectonic plates of earth differentiates it from most other planets.

8. Earth has a solid crust unlike the gaseous planets.

9. Earth has been gifted with a medium sized star which release solar winds and protect us from the harmful radiation of outer space.

The secretion of a signal molecule by a cell into the local environment
Elodia [21]

Answer:

paracrine signaling.

Explanation:

Chemical signaling between cells is one of the most important ways that activities of tissues and  organs are coordinated. The nervous system is the other major coordinating system in animals,  but even here chemical signaling is used between adjacent neurons. The mechanisms involved are  described as either being paracrine, autocrine, intracrine, endocrine, neuroendocrine or  pheromones. Paracrine signals diffuse locally and act on neighboring cells.
