how is carbon transferred from the biosphere to the hydrosphere?
Answer:
Animal and plant respiration place carbon into the atmosphere. When you exhale, you are placing carbon dioxide into the atmosphere. Plants use carbon dioxide from the atmosphere to make the building blocks of food during photosynthesis. Carbon is found in the hydrosphere dissolved in ocean water and lakes.

the three steps that are required for dna replication are
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
The three steps that are required for DNA replication are initiation, elongation and termination.
What is DNA replication ?The process in which DNA of a cell under go duplication to produce two copies during S-phase of cell cycle called as DNA replication.
It involves 3 steps such as initiation step where the origin of replication of DNA molecule undergo unwinding into two DNA strands.
An incomplete unzipping by forming replication fork is created is catalyzed by the helicase enzyme.
Secondly in elongation step the DNA polymerase enzymes make the complementary sequence against each parent template strand.
It is an unidirectional, one strand which is synthesized in a continuous manner called leading strand, the strand which is synthesized in a discontinuous manner called lagging strand with Okazaki fragments.
Termination occurs in the last step, when the parent molecule has been completely replicated.

the words ""antigen"" and ""virus"" are interchangeable.
Answer:
False
Explanation:
A virus (which is a pathogen) has a lot of antigens on its surface, so they can't be used interchangeably.
Blood vessel diameter fluctuates between being constricted and being dilated. This is the primary contributor to blood pressure. In order for blood vessels (arterioles) to maintain a steady pressure, there must be a prolonged presence of what ion in the smooth muscle cell's cytosol
In order for blood vessels to maintain a steady pressure, there must be a prolonged presence of CALCIUM ions in the smooth muscle cell's cytosol. This ion initiates smooth muscle contraction.
Arterioles are blood vessels that have muscular walls consisting of one or two layers of smooth muscle cells.
Calcium (Ca2+) ions start the contraction of the smooth muscle cells by binding to calmodulin protein and thereby activating myosin.
In consequence, Ca2+ ions act as a secondary messenger that activates calmodulin, stimulating the phosphorylation of the myosin light chain and thus triggering muscle contraction.

On the map, take a close look at the boundary along southern California and Mexico’s Baja California Peninsula. The arrows on the map show the direction and speed of the plates along this boundary in millimeters per year. Based on the speed and direction of the arrows, identify the type of plate boundary at this location. Which landforms or events are likely to occur there as a result? (Hint: It may be helpful to model the motion of the plates using your hands or pieces of paper.)
Explanation:
Thus, at convertgent boundries, continental crust is created and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundry
The area around the convergent boundries, continental crust is created then the oceanic crusts were destroyed.
What are land forms?The term land form is used to describe the physical features that describe the geography of any particular area.
Looking at the map, in the area around the convergent boundries, continental crust is created then the oceanic crusts were destroyed.

There are over 1300 imperilled species in the United States. 33.4% has been caused by introduced species or more so invasive species
The invasive or introduced species in the United States has seen an economic impact since the damage can be seen in both animals and plants. Now with an invasive species brought about, the naturally occurring species are left fighting for a spot in the habitat and lose in most cases. So economically, the United States has to spend money to get rid of the invasive species
Some of the invasive species have been known to live all year long, and so during the winter seasons, they act as food sources to birds and other animals.
