Explanation:
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.

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.

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.

Why is apoptosis important to cells.
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.

Answer:
Increased Production of Photosynthesis
Explanation:
Carbon dioxide make plants more productive because photosynthesis relies on using the sun's energy to synthesise sugar out of carbon dioxide and water so a Carbon interaction with any plant species would alternate in photosynthesis. Plants and ecosystems use the sugar both as an energy source and as the basic building block for growth.
the words ""antigen"" and ""virus"" are interchangeable.

False
Explanation:
A virus (which is a pathogen) has a lot of antigens on its surface, so they can't be used interchangeably.

How are thorns and spines related to drought resistance?
Answer:
To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.
The main structural distinction between the left atrium and the right atrium is that the left atrium has the _____, and the right atrium does not.
a. auricle
b. pectinate muscles
c. cardiac muscles
d. chordae tendinae
Given our understanding of cardiac anatomy, we can confirm that the main structural distinction is that the right atrium has the pectinate muscles, while the left one does not.
Firstly, we must address that there is a wording issue with the question. In reality, it is the right atrium that contains the pectinate muscles. The remaining options either correspond to both atrium, or neither.
The auricle is another word for ear. This is a cavity present on both the right and left atrium which allows them to extend their blood carrying capacity in situations of need. This option cannot be correct for the question since both atria possess one.
As for options b and c, cardiac muscle is present in the entirety of the heart. Cardiac muscle is the muscular cells that make up every wall and cavity of the heart and allow it to complete its unique function. Chordae tendinae, are fibers present in the ventriculus that attach the walls to the tricuspid valve, these are not present in either of the atria.
Therefore, we can confirm that though the wording is off, the intended correct answer is pectinate muscles, given that the right atrium is characterized by their presence, whilst the left atrium contains few, if any, of these muscles.
