8 0

Answer:

Explanation:

I would say no because hormones usually travel long distances via blood. This question makes it seem like it is short distance and does not talk about how the secreted entity travels. So my bet is no.

The Steady State Theory state that the density of the universe was remaining constant.

<h3>Steady State Theory:</h3>

In cosmology, a steady-state theory is a perspective that holds that the universe is constantly expanding while maintaining a constant average density. According to this theory, the matter is continuously created to form new stars and galaxies at the same rate that older ones fade away due to their expanding distance and accelerating recession. The average density and configuration of galaxies are the same as any location in a steady-state universe, which has no beginning or end in time.

British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle first proposed the hypothesis in 1948. Hoyle expanded on it in order to address issues that had come up in relation to the alternative big-bang theory. According to the hypothesis, in order to maintain a constant average density of matter across time, the new matter must constantly be created, primarily as hydrogen. With nearly five times as much dark matter, the amount needed is small and not immediately observable: one solar mass of baryons per cubic megaparsec every year, or one hydrogen atom per cubic meter every billion years.

Explain why the intracellular and extracellular surfaces of the phospholipid bilayer are polar.
yulyashka [42]

Answer:

A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails. ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water.

What do high and low air pressure systems mean in terms of density?
Arada [10]

<span>There are two physical differences between Low pressure systems and </span>High pressure systems.

First, is the circulation surrounding them.

Secondly, is the atmospheric motion that they cause.

Low pressure systems circulate counter-clockwise. High pressure systems circulate clockwise. These "motions" are the building blocks in our atmosphere. They give us our weather.

A Low’s counter-clockwise circulation forces air upward (ultimately resulting in condensation, cloud formation and ultimately precipitation). A High’s clockwise circulation causes a sinking motion in the atmosphere, resulting in fair/clearer and often sunnier skies.
