Answer:
New Moon
Explanation:
This is when the moon is between the sun and the earth. The side of the moon that faces the earth is in darkness hence cannot be viewed with the aided eye from the earth and the sun and moon rise and set together. During the daytime the glare of the sun makes it harder for us to see the new moon. A slight halo is visible around the moon because some light from the sun which is behind the moon goes around the. When the new moon just crosses the elliptic orbit blocking the sun rays from reaching earth and causing a shadow over the earth, this is when a solar eclipse occurs. You realize that the moon’s orbit is inclined relative to the ecliptic orbit hence solar eclipse does not occur with every new moon.
Explanation:
cAMP binds to protein kinase A and activates it, allowing PKA to phosphorylate downstream factors to produce a cellular response. cAMP signaling is turned off by enzymes called phosphodiesterases, which break the ring of cAMP and turn it into adenosine monophosphate (AMP).
Answer:
✔
Explanation:
genus (pl. genera)
in the modern classification system, a subdivision of a family; includes one or more species of organisms
<span>A. endoskeleton
</span>Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.
Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
The amount of carbondioxide in the atmosphere would greatly increase if there were fewer plants.
(Plants) is the answer.
