<h2>When too walk your dog you are using energy from the sunlight to power this activity</h2>

Explanation:

The ultimate source of energy in the ecosystem is the sun. When we take our dog for a walk, we are utilizing energy stored in our body that we obtained food. We must have obtained that from either plants or animals. The animal in turn must have obtained its food from plant. Plants are the organisms in the food chain who can convert the energy from the sun into the chemical energy. So, we can say that when we walk our dog we use energy from the sunlight to power this activity.

How do the main sequence stages of these two sizes of stars differ?
xxTIMURxx [149]
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^ 

Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years 

Massive hot supergiants will live for just a few million years. 

A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!

The model below shows the structure of a portion of a plasma membrane in an animal cell. The model shows the structure of a port
Romashka-Z-Leto [24]

Answer:

The amphipathic property of the phospholipids that constitute the membrane

Explanation:

It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.

The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.

The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.

This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.

Last week you were wondering what Jessica and Tom's babies might look like with respect to their eyebrows and earlobes (both Tom
mash [69]

Answer:

25%

Explanation:

The possible genotypes and phenotypes are:

  • EE or Ee: thick eyebrows
  • ee: thin eyebrows
  • FF or Ff: free earlobes
  • ff: attached earlobes

Tom and Jessica have thick eyebrows and free earlobes. Tom's mother has attached earlobes, so Tom must have inherited an <em>f</em> allele from her, and because he has free earlobes he must be heterozygous<em> Ff. </em>We assume Jessica is homozygous for free earlobes <em>FF</em>.

Tom's mother and Jessica's father have thin eyebrows, so they are both <em>ee</em> and therefore both Tom and Jessica must be heterozygous <em>Ee</em>.

From the above information, Tom has the genotype EeFf and Jessica is EeFF. If you do a Punnett Square of this cross, you'll get that the probability of having a child with free earlobes and thin eyebrows (eeF_) is 25%.
