Answer:
A skeletal muscle called Ligaments connects two bones together by the joint. Those muscles moves the bones
Answer:
Laws of stratigraphy help scientists determine the relative ages of rocks. This law states that deeper rock layers are older than layers closer to the surface. An unconformity is a gap in rock layers. They occur where older rock layers eroded completely before new rock layers were deposited.
Explanation:
The study of rock strata is called stratigraphy. The laws of stratigraphy can help scientists understand Earth’s past. The laws of stratigraphy are usually credited to a geologist from Denmark named Nicolas Steno. He lived in the 1600s.

A subsurface rock layer that is composed of clay and bedrock and is an impermeable barrier to water flow would be described as a(n) <u>aquifer(option b)</u>.
An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt).
The study of water flow in aquifers and the characterization of aquifers is called hydrogeology. Aquifers occur from near-surface to deeper than 9,000 metres (30,000 ft).
There are three different types of aquifers: confined, unconfined, and perched. Recharge zones are typically at higher altitudes but can occur wherever water enters an aquifer, such as from rain, snowmelt, river and reservoir leakage, or from irrigation.

Answer;
-Over 4000
Mathematically, the biomass in the ocean contributes over 4000 times more grams of NPP per year per gram than an equivalent gram of plant biomass in a terrestrial ecosystem.
Explanation;
-Living biomass forms a tiny fraction of Total Ocean carbon but has a very significant influence on the ocean carbon cycle. Every gram of biomass of the primary producers in the ocean contributes more to NPP per year than plant biomass of terrestrial ecosystems.
-In marine ecosystems, phytoplankton is the main source of primary production. The nutrient availability cycles make it important to distinguish between new and regenerated primary production ; the former identifies the annually renewed nitrogen, while the second measures the rapid cycling of nitrogen through ammonia availability.
Because they have selective mutation and each time an organism/animal reproduces they get half of their parents chromosomes. therefore each and every single organism/animal will be unique
